What fertilizer is most taboo for planting taro?What are the consequences of applying it?

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 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 farm 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 then 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.

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 requires loose soil and strong water and fertilizer retention capacity, and the application of rotted farmhouse fertilizer and active silicon-magnesium-calcium fertilizer as base fertilizer can meet this requirement. 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, and the root system of taro is deeply distributed

Because I am growing vegetables on the rooftop, the soil layer is shallow, so I first add humus to the soil, such as rotten vegetable leaves and kitchen waste, ferment and rot, add an appropriate amount of compound fertilizer after rotting, plant the taro, and wait for the taro to grow up, and then add self-foaming liquid fertilizer, potassium fertilizer solution, etc.

<> tuber growth period is the expansion period, which generally lasts for 45 days, and 80% of the yield is formed during this period, so the amount of fertilizer required at this time is very large, and it is necessary to apply 1 fertilizer and combine foliar fertilization. <> tuber growth period is the expansion period, which generally lasts for 45 days, and 80% of the yield is formed during this period, so the amount of fertilizer required at this time is very large, and it is necessary to apply 1 fertilizer and combine foliar fertilization.

Taro is generally planted in February and March, and the growth period is about 8 months, and the amount of fertilizer is large, but it cannot be blindly fertilized according to habits. According to practice and research, in order to plant taro well, the combination of organic fertilizer and inorganic fertilizer, and the application of potassium fertilizer are more conducive to improving yield. Taro likes a hot and humid environment, and is generally planted in the southern part of our country, and the more people plant it in the south.

Taro is generally not planted alone, it is interplanted with other crops, such as Tengzhou City, Shandong Province, China, which is an area with a large taro cultivation area.

The root of taro is a fleshy fibrous root, the penetration of the soil is weak, like loose and deep soil, generally choose the deep tillage layer, good structure, fertile soil, sufficient nutrients, good aeration, drought watering, waterlogging can drain the plot, neutral, slightly acidic soil is appropriate. I used to grow taro for a few years, using small taro as seeds, ditching and sowing, and planting fertilizer between seeds. Since it was the first year to plant taro, I didn't think too much about it, and the chemical fertilizer used was the fertilizer left over from planting wheat, which was a compound fertilizer containing chlorine.

In the vigorous growth period, the soil has become a ridge, and long-lasting fertilizers such as well-rotted livestock and poultry manure or cake fertilizer can be applied, and phosphorus and potassium fertilizers can be used to promote bulb expansion and starch accumulation. In the later stage of growth, fertilizer and water should be controlled, especially nitrogen fertilizer should not be too much, so as to prevent the growth of the aboveground part and the underground part from being uncoordinated, delaying maturity and reducing the yield.

First of all, it is necessary to pay attention to the top dressing for many times, the general seedling growth is slow, the fertilizer is not much, only a small amount of thin farmer's organic liquid fertilizer is needed to promote root growth. Later, with the gradual growth of vigorous growth, it is necessary to combine soil topdressing 3-4 times, the concentration and dosage are increased step by step, and the fertilizer water should be controlled in the later stage of growth, so as to avoid the vigorous growth of new leaves, the delay of maturity, and the yield and quality of bulbs are reduced.

Sufficient base fertilizer can meet the fertilizer demand of taro throughout the growth period. Before applying base fertilizer, we should first plow the soil, so that it is convenient for us to apply base fertilizer and for taro with weak root system at the seedling stage to take root.

Sufficient basal fertilizer can meet the fertilizer demand of taro throughout the growth period. Before applying basal fertilizer, the soil should be deeply cultivated. This makes it easier for us to apply basal fertilizer and also makes it easier for taro to take root, because taro has a weak root system at the seedling stage.

For the selection of base fertilizer, Lao Zhao suggested that socks should use farmhouse fertilizer, which has sufficient nutrients and contains many mineral elements. The fertilizer effect of farmhouse fertilizer lasts for a long time, and it is not easy to cause soil fertilizer deficiency. Farmyard manure loosens the soil and makes taro roots easier to grow.

Taro has a long growth time, high yield, and a large amount of fertilizer, so in addition to the base fertilizer at the foot, it should also be applied to the top fertilizer in stages. If the soil is poor or the growth of the seedling stage is weak, it can be fertilized at the beginning of the seedling stage, and the surface fertilizer is mainly nitrogen fertilizer, and the amount of surface fertilizer should be less. In the flowering period and the early and middle stages of stem and leaf growth, top fertilizer 2 3 times, the amount of fertilizer is less before and more later, and gradually increases, nitrogen, phosphorus, potassium fertilizer should be used together.

In the late stage, top fertilizer should be controlled to avoid late ripening. Sufficient basal fertilizer can meet the fertilizer needs of taro throughout the growth period.

The soil should be deeply cultivated before applying basal fertilizer. This makes it easier for us to apply basal fertilizer and it is also easier for taro to take root, because taro has a weak root system at the seedling stage. The taro growing season is in January, when there is more rain and the soil is too wet, so the use of plant ash can dilute the excess water in the soil.

Top dressing in taro growth and taro expansion period, mainly phosphorus and potassium fertilizer, such as ammonium bicarbonate 30-45 and potassium dihydrogen phosphate 40-50 per mu, promote tuber expansion and growth, and apply less nitrogen fertilizer, otherwise the stem and leaf growth will quickly consume nutrients, which is not conducive to the growth of tubers.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

If there is too much topdressing, it may lead to overnutrition of taro, and if the bacterial fertilizer is too small, it may lead to stunted growth of taro, and at the same time, we should also choose a better fertilizer to better let the taro grow.

When starting to top dressing, it is necessary to combine weeding, according to the planting method of taro to take the same fertilization method, manure can be used in the early stage, and various fertilizers can be applied in the later stage.

You can use bulking fertilizer, but also pay attention to keep the soil moist, to irrigate in the morning and evening, but also to pay attention to the drainage of the soil, it is best to control the amount of watering in the 20 days before harvesting.

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."

Taro is an herbaceous plant. The flesh of taro is delicious, taro is sweet, and it is very popular with everyone, so do you know how to fertilize when planting taro? Let me introduce to you the characteristics and methods of taro fertilization.

Fertilization characteristics and methods of taro

1. Fertilizer characteristics

1. Hongxi taro requires loose soil, strong water and fertilizer retention ability of the soil, and the application of organic fertilizer compost, straw spirit, active calcium, silicon and magnesium fertilizer as base fertilizer can meet these requirements. Lead Chang.

2. Taro is a potassium-loving crop, and there are a large number of active potassium and phosphorus nutrients in LPK chemical fertilizer to meet the demand for potassium in taro.

3.The bulb swelling and starch accumulation, aroma, disease resistance and storage and transportation resistance of taro were mainly due to the use of LPK fertilizer and active calcium-silicon-magnesium fertilizer, which had ideal effects.

4. Rapid replenishment of nutrients and prolongation of functional leaf senescence can be foliar spraying of beauty green.

II. II. II, fertilization method

1. Basic fertilizer.

The first is the application of fertilizer, and the agricultural fertilizer used at the time is made from straw decomposition and applied according to the conventional customary dosage.

Secondly, apply 50 kg of active calcium-silicon-magnesium fertilizer per mu (can be mixed with farmhouse manure for compost, or mixed with composted farmhouse fertilizer).

2. Top dressing. <>

The amount and frequency of fertilization should be diagnosed according to the nutrients in the field, and the plots with sufficient bottom fertilizer and good fertility can be fertilized appropriately. It can be carried out at the same time as weeding, soil cultivation and watering. The second time is around the 4-leaf stage, and the second to fourth time is at the 7-14 leaf stage, with an interval of two weeks between the two applications.

The second top dressing: LPK fertilizer 4 kg mu + 5 to 10 kg of urea per mu, 200 times with water, or ditching and applied next to the roots. Clause.

3. 4 Top dressing: LPK 3 to 4 kg per mu + 1 to 3 kg of urea per mu, drenched with water 200 times, or ditched next to the roots.

3.Foliar sprays.

In the peak season (4-14 leaf stage), combined with field nutrition diagnosis, it is found that it is insufficient or combined with pest control foliar spraying of Meilu two to three times. Watering 400 to 800 times, the leaves on both sides should be moist and not dripping, and you need to supplement the spray after 8 hours to prevent rain.
