What fertilizers need to be applied cautiously during the growing period of taro?

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.

In the whole growth process, urea and compound fertilizer can be applied, and photosynthetic nutrient film fertilizer can also be sprayed, which can improve chlorophyll, photosynthesis and nutrients, and help plants absorb a lot of light energy, light, light fertilizer, compatible with conventional fertilizers, nutrients to supply plant growth and development. They will no longer blindly pursue the growth of taro seedlings in the early stage of taro growth, and do a good job of corresponding control work, so that taro can be managed in the later stage. Therefore, when these people apply base fertilizer to taro, they often pay attention to the combination of organic fertilizer and phosphorus and potassium fertilizer.

Spraying herbicides and mulching film: In order to inhibit the germination of weed seeds, the soil sealant "Hoene" can be used to spray the water. It can be sprayed in the early morning or when the soil surface is wet before the dew dries in the morning, so as to facilitate the conjunctiva of the drug and improve the control effect.

<> taro root is a fleshy root, easy to get hurt, so to plant taro in a deep and fertile, air permeability and drainage good soil, in the year before the deep ploughing, it is recommended to apply fermented farm fertilizer 1000 1500kg, 20 kg of superphosphate, 100 kg of plant ash per mu. Crops such as wheat and corn can be planted with chemical fertilizers, but taro with chemical fertilizers is not effective, easy to compact the soil, it is best to use organic fertilizer, not only fertile land, but also long-lasting fertilizer effect. After the land is selected, it is deeply turned and 2000 kg of organic fertilizer poultry manure is applied per mu, and 60 kg of compound potassium fertilizer can be mixed.

Then dig a trench 50 cm wide and 35 cm deep according to the row spacing of about 100 cm for later planting.

In the paddy field that has never planted taro! If water, fertilizer, and pests and diseases are well managed in the first year! Generally, each one reaches 3 catties to 6 catties!

The best single can weigh up to 7-9 pounds! It's easy to plant. Pre-Seedling Period:

Apply "basal fertilizer.""About 2500 kg of organic fertilizer per mu of land, or 6000 kg of soil miscellaneous fertilizer with high organic matter content, can also be applied to the farmhouse fertilizer, active silicon, magnesium and calcium fertilizer. Base fertilizer: apply farmhouse fertilizer that has been rotted by stalks, such as cow manure, sheep manure, pig manure, and use it after fermentation.

As for the dosage to be adjusted appropriately according to the fertility of the soil, it is recommended to have about two taels per plant.

First of all, we must pay attention to the amount of fertilizer when fertilizing, and the most important thing is to pay attention to the number of times in this process, and it is best not to fertilize often, which is likely to have a certain impact on the yield.

Apply plantar fertilizer. 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.

For the selection of base fertilizer, it is recommended to use farmhouse fertilizer for three reasons: First, farmhouse fertilizer has sufficient nutrients and contains more mineral elements. Second, the fertilizer effect of farmhouse fertilizer lasts for a long time, and it is not easy to cause soil fertilizer deficiency.

Third, farmhouse fertilizer has the effect of loosening the soil, which is more convenient for the growth of taro rhizomes.

1. Taro is very sensitive to temperature, if it is in a high temperature environment, it is likely to cause taro to grow slowly, so when we plant taro, try to control the temperature at about 22 degrees, 2. Before planting taro, we must treat the soil, as we all know, the fruit of taro is grown in the soil, and the requirements for the soil are very high, so when we plant taro, we must carry out a deep turn on the soil, and we are in the deep turn. Try to control the depth at more than 40 cm, because at this time of the soil, there may be some pests left, the deeper the depth of the deep turn, you can dig out the insects and diseases inside, and after the deep turnover, we also have to apply enough low fertilizer, it is best to use some fully rotted farm fertilizer, which can make the soil more fertile.

Taro needs a large amount of fertilizer, long growth period, first of all, apply foot fertilizer, 2000 kg of high-quality organic fertilizer per mu, 60 kg of 48% potassium sulfate compound fertilizer (16-16-16), according to the row spacing ditch application. Top dressing should be applied in stages, 2-3 times in the seedling stage, germination stage and bulb growth stage, and phosphorus and potassium fertilizer should be the main fertilizer.

Taro needs to be turned more than 40 cm deep before sowing, which is conducive to bulb expansion and increase yield, which is one of the important measures for cultivation. Before deep turning, 5000 kg of organic fertilizer, 35 kg of diammonium phosphate, 50 kg of three-element compound fertilizer, 100 kg of bone meal as base fertilizer, in mid-July, taro is prosperous for a long time, and an appropriate amount of ammonium bicarbonate, diammonium phosphate and other fertilizers should be applied.

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.

Taro likes more fertilizer, the growth period is long, should be topdressing many times, mainly fast-acting fertilizer, generally topdressing 4 5 times. The amount and frequency of top dressing should be based on the field nutrition diagnosis, and the plots with sufficient base fertilizer and good fertility can be combined with appropriate amount of weeding fertilizer, soil cultivation and watering at the same time.

It is necessary to pay attention to the growth cycle, understand the yield of taro, pay attention to the soil situation, so as to carry out reasonable fertilization. Be sure to choose the right fertilizer, pay attention to the conditions of top dressing, ensure the growth of taro, pay attention to the requirements of fertilization, and understand the specific yield.

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.

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.

To cultivate taro, it is best to use organic fertilizer, which can improve the soil structure, improve soil moisture, and promote the root development of taro, so as to provide a strong prerequisite for foliar photosynthesis. The so-called deep roots and leafy leaves can obtain high yields. As for bulking agents, if you eat them yourself, it's better not to use them, after all, hormones are also harmful.
