Abstract
The invention relates to a formulated fertilizer for sweet potatoes, which is researched in accordance with the principle of balanced fertilization, the law of barrel, and the data from soil testing and assaying, aiming at the unscientific fertilization phenomenon that only nitrogenous fertilizer is always used in the production of sweet potatoes regardless of the nutrient supplying capability of soil and regular fertilizer requirement pattern of the sweet potato. The formulated fertilizer for the sweet potatoes is prepared by mixing 2.8-3.2 parts of urea, 2.8-3.2 parts of calcium superphosphate, 0.8-1.2 parts of calcium magnesium phosphate and 2.8-3.2 parts of muriate of potash according to proportion; and packaging after mixing. The formulated fertilizer has been popularized for a decade; based on the application of many peasants, the yield by applying one bag of the formulated special fertilizer for sweet potatoes is higher than that by applying 3-5 bags of urea per mu.
Description
Technical field
The present invention relates to the chemical fertilizer field of fertilization compositions based on earth measurement, be specifically related to special formulated fertilizer for sweet potatoes.
Background technology
At in Ipomoea batatas produces, occur no matter soil feeder capability and Ipomoea batatas regulation of fertilizer requirement, the phenomenon that do not apply fertilizers scientifically of long-term single nitrogen fertilizer application, we are according to the principle of balance fertilizing " wooden barrel law ", and the data according to surveying the soil chemical examination work out special formulated fertilizer for sweet potatoes.
Summary of the invention
The objective of the invention is to the principle according to balance fertilizing " wooden barrel law ", the preparation special formulated fertilizer for sweet potatoes is the new space of increasing peasant income joint money developing.
The present invention has adopted following technical scheme:
According to production requirement, select urea, calcium superphosphate, calcium magnesium phosphorus, four kinds of sources of manure of Repone K for use, carry out blending according to following ratio, be 2.8～3.2 parts in urea, 2.8～3.2 parts of calcium superphosphate, 0.8～1.2 part in calcium magnesium phosphorus, 2.8～3.2 parts in Repone K, bag distribution packaging after the blending is put on market.
Advantage of the present invention is:
1, high-quality calcium magnesium phosphorus powder, the general calcium of fusion particle, urea make its material surface form one deck calcium magnesium phosphorus powder film, have prevented that not only general calcium and urea from directly contacting the deliquescence phenomenon of appearance, after being manured into soil, also can reduce the utilization of phosphorus fixation and slow-release nitrogen.
2, the free acid in the calcium superphosphate can promote the dissolving of calcium magnesium phosphorus again.
3, in year surplus this prescription fertilizer has promoted ten, friend uses through vast farmers, uses one bag of special formulated fertilizer for sweet potatoes for every mu, the comparable output height of using 3～5 bags of urea.
Embodiment
According to production requirement, select urea, calcium superphosphate, calcium magnesium phosphorus, four kinds of sources of manure of Repone K for use, carry out blending according to following ratio, be 2.8～3.2 parts in urea, 2.8～3.2 parts of calcium superphosphate, 0.8～1.2 part in calcium magnesium phosphorus, 2.8～3.2 parts in Repone K, bag distribution packaging after the blending; This is filled a prescription in producing process for preparation, 300 jin in urea of each composite unit, 300 jin of calcium superphosphate, 100 jin in calcium magnesium phosphorus, 300 jin in Repone K, totally 1000 jin, after the stirrer blending, reaching nitrogen, phosphorus, potassium total nutrient is 38%, and three's ratio is 14: 6: 8 requirement, and concrete blending parameter is seen following table:
Claims (1)
