Problems solved by technology

However, after excessive use of chemical fertilizers, not only the yield cannot be maximized, but the water content of potatoes is too high, it is not easy to store, and it is easy to rot. Potato cells contain inorganic salts that have not been metabolized, causing food safety problems
It is easy to cause diseases and insect pests during the cultivation process, and then spray pesticides continuously, which not only increases production costs, but also easily causes pesticide residues
In addition, excessive use of nitrogen fertilizers that cannot be absorbed by potatoes will evaporate into the sky in the form of ammonium nitrogen or nitrate nitrogen, causing smog

Embodiment 1

[0042] Under the premise of not using the base fertilizer, apply a) the fertilizer for the first time when the potato seedlings grow to a height of about 10cm, and the amount of fertilizer applied is 40kg / mu; Carry out topdressing for the second time, and the amount of fertilizer applied is 35kg / mu; a total of 75kg / mu.

[0043] Specific topdressing method: You can use machinery to evenly spread the potato seedlings around the potato seedlings and cover them with soil. You can also dissolve the fertilizer in water according to the water addition of 50 to 100 times the mass ratio of the above a) fertilizer, and spray irrigation, drip irrigation or The micro-spraying equipment is directly sprayed in the potato field; it is also possible to directly dissolve a) fertilizer in clear water in the field, and then apply it to the potato field along the watering and irrigation flow. The experimental results of planting potatoes in the actual field show that the yield of potatoes per mu ...

Abstract

A special formula fertilizer for potato cultivation is disclosed. The fertilizer is composed of the following ingredients: KNO3 or KCl or K2SO4, Ca(H2PO4)2.H2O, CO(NH2)2 or (NH4)2SO4, or 5Ca(NO3)2.NH4NO3.10H2O, MgSO4.7H2O or MgSO4.H2O, and FeSO4.7H2O. In comparison with existing conventional fertilization methods (a composite fertilizer, urea, diammonium phosphate, calcium superphosphate and potassium dihydrogen phosphate), the special formula fertilizer for potatoes has the following advantages: the application method is simple and convenient; plants grow strongly; the fertilizer is resistant to diseases and pests; pesticide spraying frequency is reduced; cost of pesticides and labor cost are reduced; about 10% of yield per mu can be increased; quality and taste of potatoes are improved; the original flavor of potatoes is recovered; and storability of potatoes is raised. The invention has very wide application value and market prospect.

Description

technical field [0001] The invention relates to the technical field of field agricultural production, and mainly relates to a potato special formula fertilizer for potato cultivation. Background technique [0002] Potatoes are one of the most important economic crops in my country. Since 2015, the Ministry of Agriculture has classified potatoes as food crops. Therefore, its economic value and social value are increasingly important. The planting range of potatoes covers a large area of ​​my country. Due to its short growth period, it is especially suitable for planting in alpine mountainous areas and plateau areas. It is one of the most important crops in underdeveloped areas in my country. According to statistics, my country's potato planting area is 21.55 million hectares, with a total output of 320 million tons. The planting area accounts for 18% of the world and 70% of Asia, ranking first in the world. However, due to the pursuit of yield and economic benefits in rece...
