Description
Technical field
The present invention relates to broadacre agriculture production technical field, a kind of horse for potato culture is related generally to
Bell potato formula fertilizer special.
Background technology
Potato is one of most important industrial crops of China, and potato is classified as into grain again from the Ministry of Agriculture in 2015
Food crop.Therefore its economic worth and social value become more and more important.The plant scope of potato covers the big of China
Area territory, because its growth period is shorter, is particularly suitable for high and cold mountain area and highlands plantation, is China
One of most important crops in low developed area.The potato planting face of China is 21,550,000 hectares according to statistics,
Total output reaches 3.2 hundred million tons.Cultivated area accounts for the 18% of the world, accounts for Asia 70%, occupies first place in the world.But,
Because year after year in order to devote exclusive attention to output and economic interests, when potato is planted, the usage amount of chemical fertilizer increases in recent years,
100kg/ mus or so from before 10 years increases to current 200kg/ mus, even up to 250kg/ mus.Although
The yield of the increase potato when soil fertility is relatively low with dose is accordingly improved.But being excessively used
Not only yield can not reach maximization after fertilizer, can cause potato water content too high on the contrary, be difficult storage, hold
Easy evil mind is rotted, and food-safety problem is produced containing the inorganic salts either with or without metabolism in the cell of potato.
Easily trigger pest and disease damage in cultivation, then constantly spray insecticide, not only increase production cost, be also easy to
Cause residues of pesticides.Additionally, can be with ammonium nitrogen or nitre state after being excessively used nitrogenous fertilizer and can not being absorbed by potato
The form of nitrogen is evaporated to day and triggers haze in the air.
Therefore, applicant goes out one kind according to the nutritional physiology parameter designing of potato is suitable for potato health
The formula fertilizer special for growing, while high yield is ensured, improve fertilizer utilization rate, reduce ammonia nitrogen and
The discharge of phosphorus, improves the disease resistance of potato, reduces Pesticide use amount, improves the quality and mouthfeel of potato,
Recover the original local flavor of potato, while improving the storage property of potato.
