Scientific fertilization is conducive to the growth of crops, what fertilizer is taro most afraid of

1. Fear of unrotted "raw manure". The by-products caused by this kind of alcohol will cause taro leaves to turn yellow, grow slowly, if the amount of livestock and poultry manure that is not sufficiently rotted is large, and even cause taro to grow and develop in this field, the economic benefits of planting taro, I don't say that everyone can guess, it is very bad.

2. Fear of fertilizers containing chlorine. In the soil where chlorine-containing fertilizer is continuously applied, the yield of taro will be lower year by year, the sweet and fragrant taste will be reduced, and the starch content seems to be reduced. Therefore, the fertilizer that taro is most afraid of, and the fertilizer containing chlorine is also a kind of fertilizer.

If you must apply fertilizers containing chlorine, you should control the amount used, preferably one year apart.

It should contain chlorine. The use of fertilizers of this element will cause the taro to taste very poor, and it will also lead to a serious decrease in yield.

Fertilizers containing chlorine are not rotted "raw manure, so when planting, be sure to avoid it."

There is no definite fertilizer that cannot be used for taro, but any fertilizer applied to it should be done in a way or not. In the first 15 days of planting, it is necessary to apply less fertilizer, or choose not to apply it directly, and make sure that the root system begins to germinate and grow before applying. Nitrogen fertilizer can be applied in the early stage, and phosphorus and potassium fertilizer can be appropriately supplemented in the later stage.

In addition, the amount of fertilizer should be controlled well to avoid fertilizer damage. If you want it to grow vigorously, you also need to pay attention to field management.

There are contraindications to taro fertilization, which fertilizers are not suitable for taro? Generally speaking, it is best to use less chlorine-based fertilizers, which will not affect the yield, and the appropriate dosage is fine, and the later use of high potassium will promote the transfer of photosynthetic products to the tuber.

At present, there is no fertilizer that cannot be used, but any fertilizer applied to taro should be paid attention to. At the beginning of planting, a small amount of fertilizer should be applied in about 15 days, and then applied after the roots begin to germinate and grow. Nitrogen fertilizer can be applied in the early stage, and phosphorus and potassium fertilizer can be appropriately supplemented in the later stage.

Taro is suitable for growing in soils with strong water and fertilizer retention ability, especially in soils rich in organic matter, which is more likely to obtain high quality and high yield. Generally, taro can be grown in shallow water or dry land. Taro has fleshy fibrous roots and poor soil permeability.

Therefore, when planting taro, we should first pay attention to the cultivation of soil fertility.

The planting of taro, from planting to harvesting, can generally be divided into 5 times of top dressing. The first time is called seedling fertilizer, and the second time is called fertilizer fertilizer. During the taro growing season, a third fertilizer is applied.

When the small taro is born next to the taro, a fourth fertilizer can be applied, and the last fertilizer strengthens the taro. This fertilizer plays an important role in increasing taro yield. If the fertilizer is reasonable and sufficient, the taro yield will be greatly increased.

Specific methods of taro fertilization:

1. Seedling fertilization, timely application of taro fertilizer after seedlings emergence, to achieve taro seedlings strong and developed root system. Before the 4-leaf stage, the new taro seedlings have weak fertilizer absorption and water absorption ability, and the amount of fertilizer required is small, but the amount of fertilizer required is fine. During the taro growing season, weeds are often accompanied.

At the same time, the drought tolerance is not strong. In addition to cultivating and weeding, it is easier to increase the ground temperature after loosening the soil, improve the ability of heat preservation and moisture retention, and is conducive to root growth. This time, the fertilization should be thin but not thick, and more per mu.

Some choose compound fertilizer, about 5 kg per mu, which can also play a better role in seedling raising. At the same time, foliar fertilizer + brassinolide was sprayed to promote the slowdown of seedling growth.

2. Tillering fertilizer, taro tillering period, fertilization, mostly organic fertilizer and phosphorus and potassium fertilizer, can be combined with a certain amount of nitrogen fertilizer, you can choose to apply organic and inorganic compound fertilizer, or choose to use fully decomposed farmhouse fertilizer, about 1000 kg per mu, or 100 kg of soybean cake per mu, the fertilizer used must be buried 10 cm deep, which is conducive to the absorption and utilization of fertilizer in the future. At the same time, spray potassium dihydrogen phosphate aqueous solution + Tianda 2116.

3.Planting taro fertilizer is generally about a month away from the last top dressing, and the time is generally in late May. At this time, the new taro bulb begins to swell and grow.

For a more sustainable fertilizer**, top dressing should still be done this time. This time, 40 kg of beneficial microbial fertilizer + 70 kg of soybean cake + 5 kg of compound fertilizer were used. After mixing these fertilizers, they are applied to the side of the plant and covered with 5 cm thick soil, which is beneficial for the head.

4.Sun taro fertilizer, generally about 30 days, in the growth process of the taro will also be divided into a lot of small taro. In order for these new little taro to grow better, the soil should be nourished, and the taro buds should be buried in the soil at the same time.

This time the fertilization method is a repeat of the previous fertilization method. At the same time, the amount of nitrogen, phosphorus and potassium compound fertilizer will be increased to 10 kg per mu. If watering is required, an appropriate amount of amino acid water-soluble fertilizer should be applied smoothly.

5. Strong taro fertilizer, when the taro grows to July, some of the old leaves will gradually turn yellow, and the starch accumulation of taro will increase, which is the replacement of new and old leaves, and will not affect the normal growth of taro. In the open space between the two taro trees, drill holes to apply fertilizer, then carry out a large area of soil tillage, about 10 cm, to prevent overgrowth of taro leaves, and then soil tillage again according to the situation. Arid taro prefers moist soil and keeps the soil moist from beginning to end.

There must be no shortage of water when encountering water, and water plays a vital role in the growth process of taro.

Taro has a great demand for fertilizer during the growth period, generally speaking, there is no fertilizer that can not be used, only need to pay attention to the use of chlorine-based fertilizer as little as possible, if the chlorine-based fertilizer is applied too much, it may affect the yield of taro. Generally, during the growth period of taro, it is best to use a combination of farm fertilizer and chemical fertilizer, so that the taro can become larger.

Taro is a crop that likes potassium and avoids chlorine, so it must not be applied with compound fertilizers containing chlorine. When using excessive chlorine fertilizer, there will be a phenomenon of burning roots and dead seedlings in serious cases, so the amount of taro planting is not good, and chlorine fertilizer should never be applied.

Unrotted "raw manure", organic fertilizer includes a wide range of fertilizers, farm fertilizer, various crop straw, cake fertilizer, livestock and poultry manure, etc. In particular, the livestock and poultry manure that is not fully decomposed, if it is directly applied, it will cause serious discomfort to the root system of taro, and there is a burning of seedlings, etc., unrotted livestock and poultry manure in the countryside, also known as "raw manure", when the soil is applied to the manure, these raw manure will be driven by temperature, will carry out slow fermentation, the fermentation process will produce heat, organic acids, and some substances that are not conducive to the growth of crop roots, the by-products of these fermentation, will cause taro leaves to yellow, slow growth.

Taro has a long growth period and requires a large amount of fertilizer, with the largest demand for potassium fertilizer, followed by nitrogen fertilizer and the least phosphorus. For every 1000 kg of bulbs produced, kilograms of pure nitrogen, kilograms of phosphorus pentoxide, and kilograms of potassium oxide are required. Taro requires loose soil, strong water and fertilizer retention ability, and the application of organic fertilizer made of rotten stalk and active silicon-magnesium-calcium fertilizer as base fertilizer can meet these requirements.

During the growth of the plant, it is necessary to top dressing 2-3 times, and the first topdressing can be topdressed, such as urea 10-15 per mu, to promote the rapid growth of stems and leaves, enhance photosynthesis, and provide sufficient nutrients for the growth of underground tubers.

Taro is the most taboo heavy stubble, continuous cropping can reduce the yield by 20% 30%, it is best to plant on the stubble of sweet potato in the first crop, followed by peanut stubble, and the previous stubble is corn and other grasses stubble to reduce the yield by 30%. The edible organ of taro is an underground bulb, which can be topdressed with urea and compound fertilizer, etc., and can also be sprayed with photosynthetic nutrient film fertilizer, which can improve chlorophyll, photosynthesis and nutrients, and help plants absorb a large amount of light energy, light, light fertilizer, compatible with conventional fertilizers and nutrients for plant growth and development. During the growth of the plant, it is necessary to top dressing 2-3 times, and the first topdressing can be topdressed, such as urea 10-15 per mu, to promote the rapid growth of stems and leaves, enhance photosynthesis, and provide sufficient nutrients for the growth of underground tubers.

<> taro foliar fertilizer fertilization, it is recommended to use organic acid boron foliar fertilizer. It is recommended to use suspended carbohydrate soluble fertilizer on the ground, with balanced fertilizer in the early stage and high potassium fertilizer in the later stage for different periods. Combined with field nutrition diagnosis at the leaf stage, it is found that there is a deficiency disease, which can be sprayed in combination with pest control, which can make plant cell immune factors improve plant stress resistance, can make the virus DNA break and die, which is conducive to enhancing immune function, and the top dressing of taro growth and taro expansion period in the later stage is mainly phosphorus and potassium fertilizer, such as ammonium bicarbonate 30-45 per mu, potassium dihydrogen phosphate 40-50, etc., to promote the growth and expansion of tubers, and apply less nitrogen fertilizer, otherwise the stem and leaf growth will consume nutrients rapidly.

Taro has a long growth period, high yield, and a large amount of fertilizer, so it should be topdressed in batches in addition to applying sufficient base fertilizer. Seedling stage is generally not top dressing, if the soil is poor or the seedling growth is weak, you can chase 1 seedling fertilizer in the early stage of the seedling stage, top dressing is mainly nitrogen fertilizer, and the amount of top dressing should be less. Top dressing 2 3 times in the early and middle stages of the growth of the bulb and bulb, the amount of fertilizer is less before and then more, and gradually increases, and nitrogen, phosphorus and potassium fertilizers should be applied together.

In the later stage, top dressing should be controlled to avoid greedy green and late ripening.

1.If the livestock and poultry manure that is not fully decomposed, if it is applied directly, it will cause serious discomfort to the root system of taro, and there will be seedling burning. 2.

Fertilizers containing chlorine. If it is used on taro, when the soil lacks potassium, it will not show how much the yield can be reduced when applied in the first year, but it can increase the yield to a certain extent, but the taste is slightly worse.

1. Raise seedling fertilizer, after the taro is planted and the seedlings are planted, the fertilizer is applied in time to achieve the taro seedlings are strong and the root system is developed. Newly emerged taro, before the 4-leaf stage, the ability of the root system to absorb fertilizer and water is relatively weak, and the fertilizer is less, but the fertilizer required is fine, the taro growth period, often accompanied by weeds, at the same time, the ability to tolerate drought is not strong, in addition to cultivating and weeding, it is easier to increase the ground temperature after loosening the soil, improve the ability to keep warm and moisture, and is conducive to the growth of the root system. 2. Tillering fertilizer, taro tillering period, fertilization, mostly organic fertilizer and phosphorus and potassium fertilizer, can be matched with a certain amount of nitrogen fertilizer, You can choose to apply organic and inorganic compound fertilizer, or choose to use fully decomposed farmhouse fertilizer, about 1000 kg per mu, or 100 kg of soybean cake per mu, and use 100 kg of fertilizer, which should be buried 10 cm deep, which is conducive to the absorption and utilization of fertilizer in the future. At the same time, spraying potassium dihydrogen phosphate aqueous solution + Tianda 2116.

What fertilizer is good to apply to grow taro.

Taro requires a lot of potassium during the cultivation process. In general, LPK fertilizer can fully meet the potassium needs of taro, because taro contains a large amount of active potassium and phosphorus nutrients. When taro grows, the period of high fertility demand is mainly at the seedling stage, stem expansion stage and maturity stage.

When planting taro, it is best to apply urea, which can promote the rapid growth of taro stems and leaves, enhance photosynthesis, and provide sufficient nutrients for the growth of underground tubers.

Grow taro with fertilizer to increase yield.

Generally speaking, June to July of each year is the stage of rapid expansion of taro. At this time, it is best to apply fast-acting nitrogen fertilizer when topdressing, so that the taro petiole growth is hypertrophied, and the taro yield and efficiency are improved.

Plant taro and smile feast, fertilize and bloom more.

In order for taro to bloom, the fertilization method is also important. It is best to apply nitrogen, phosphorus, potassium and organic fertilizer to the plants, and dilute the fertilizer with water before each fertilization to avoid damage to the fertilizer.

Fertilization time for planting taro.

When the taro sprouts and grows four leaves, it can be fertilized. After that, the fertilization time is in mid to late April, late May, and late June. Fertilization is also required when some of the coarse leaves of the plant are found to turn yellow in late July.

Fertilization method for planting taro.

The fertilizer applied to the taro is mainly fast-acting fertilizer, and the top dressing is generally 4-5 times. The amount and frequency of top dressing should be determined according to the fertility of the planting area. Plots with sufficient base fertilizer and good fertility can be combined with an appropriate amount of weeding fertilizer.

Soil watering can be carried out at the same time, focusing on the promotion of seedling fertilizer, taro fertilizer, sun taro fertilizer, and strong taro fertilizer.

During the formation of underground bulbs, the temperature is between 25 and 30. Taro has no strict requirements for light, good negative resistance, and high requirements for moisture. Lack of water can lead to poor taro bulb development.

Taro can grow both on water and on dry land. Taro grown in water can be planted in rice paddies and ditches, while taro grown in dry land needs to be planted in moist soil. There are many taro varieties on the market, and there will be many differences in the taro varieties grown in different regions.

From the ecological aspect of taro, taro can be divided into two types: water taro and dried taro. In terms of taro types, common taro types include red-headed taro, white-headed taro, nine-headed taro, and Lipu taro. When choosing, growers need to choose according to the local planting environment, and choose taro varieties with good resistance, strong adaptability, high market acceptance, and many seeds for planting.

Taro prefers chemical fertilizers when it comes to fertilization. According to soil fertility, 4000-5000 kg of organic fertilizer, 30 kg of potassium sulfate, and 30-40 kg of superphosphate are used per mu. The basal fertilizer is tilled with the soil and penetrates deep into the soil.

Germinated taro should be dried and germinated before sowing, so that taro can germinate as soon as possible after planting and reduce diseases. Taro seeds need to choose disease-free, injury-free, well-preserved top buds, taro with a taro size of about 50 grams as seed taro. 15-20 days before planting taro, dry the taro for about 2 days, then germinate, put the taro into the germination bed, keep the temperature at about 20, about two weeks taro buds grow to about 1cm can be planted.

Good seedling management: pay attention to the sowing density when sowing taro. According to the variety and soil conditions of taro, it is generally suitable to sow about 4500-6000 taro plants per mu.

It is advisable to cover the seed buds so that the tips of the seed buds are slightly exposed in the soil layer and then cover them with plastic film. Weeding should be done before and after emergence to keep the soil moist. After the seedlings break the soil, manually help break the membrane to prevent the sun from burning the seedlings.

Check whether there is a shortage of seedlings and replenish the seedlings in time. First of all, it is necessary to understand the growth habit of taro: taro likes a warm and humid environment, and the most suitable growth temperature is above 20.

During the formation of underground bulbs, the temperature is between 25 and 30. Taro has no strict requirements for light, good negative resistance, and high requirements for moisture. Lack of water can lead to poor taro bulb development.

Taro grown in water can be planted in rice paddies and ditches, while taro grown in dry land needs to be planted in moist soil. Good seedling management: pay attention to the sowing density when sowing taro. According to the variety and soil conditions of taro, it is generally suitable to sow 4500-6000 taro plants per mu.

When sowing, take care that the seed buds are facing upwards and cover with a thin layer of soil. It is advisable to cover the seed buds so that the tips of the seed buds are slightly exposed in the soil layer and then cover them with plastic film. Weeding should be done before and after emergence to keep the soil moist.

After the seedlings break the soil, manually help break the membrane to prevent the sun from burning the seedlings. Check whether there is a shortage of seedlings and replenish the seedlings in time.
