But in general, in order to grow high-quality taro, it is necessary to solve the problem of rational fertilization of taro. Taro is a plant that likes liquid fertilizer very much, and only when it is rich in water will it increase production. In the whole process of taro planting, if scientific and reasonable fertilization is neglected, the yield and quality of taro will be affected. In the final analysis, what fertilizer is taro afraid of applying?
1 I am afraid that the "raw manure" organic fertilizer that has not been decomposed contains common fertilizers, such as farm manure, various crop straws, cake manure, livestock manure and so on. Especially if it is applied immediately, the incompletely decomposed livestock manure will lead to serious incompatibility of taro roots and adverse reactions such as seedling burning. Immature livestock manure in rural areas is also called "raw manure". When raw fertilizer is applied to soil, it will develop slowly under the pressure of temperature, and some chemicals that are not conducive to the growth and development of crop roots will be produced during fermentation.
This by-product of alcohol fermentation will cause taro leaves to turn yellow and grow slowly. If the amount of livestock manure is not completely decomposed, it will even lead to taro's failure to grow and develop in this field. I don't want to say that everyone can guess the economic benefits of growing taro, which is very bad.
Although water has a certain biodegradation effect on immature livestock manure, there are many pathogenic bacteria and diseased larvae in the manure, which is likely to cause unexpected diseases and pests in taro. During the whole dissolution process, ethylene gas produced by raw fertilizer will obviously inhibit the growth and development of roots. Therefore, taro is the most taboo to use "raw manure" that is not completely decomposed.
2 Fear of chlorine-containing fertilizers Our common chlorine-containing fertilizers generally include sodium chloride and chlorine-containing compound fertilizers. Taro likes potash fertilizer very much. Sodium chloride and ammonium sulfate, which are common in the market, have different prices because of different production processes. Sodium chloride has simple manufacturing process, belongs to alkaline fertilizer, and its price is relatively low. If sodium chloride is used in Cyperaceae crops, corn, wheat and other fields, the yield of food crops can be obviously improved.
If it is used on taro, it can be used in the first year when the soil is short of zinc, which shows how much it limits the yield. On the contrary, it can increase the yield to a certain extent, but the taste is slightly weak. If you use it continuously, you can find that the taro planted with potassium chloride is very different from the taro planted with ammonium sulfate in taste and yield.
Moreover, the yield of taro planted in the soil with continuous application of chlorine-containing fertilizers will decrease year by year, the taste of cotton will decrease, and the starch content seems to decrease. Therefore, the fertilizer that taro is most afraid of is also a kind of chlorine-containing fertilizer. If chlorine-containing fertilizers must be applied, the dosage should be controlled, preferably at intervals of one year.
