Abstract
The invention relates to a special fertilizer for milk vetch and an application method thereof. The special fertilizer for milk vetch is characterized in that nitrogen, phosphorus and potassium simple substance raw materials are compounded and pelleted in proportion, wherein the mass ratio of N to P2O5 to K2O is (0.9-1): (1.5-1.6): (0.7-0.8). The special fertilizer is innovative and has a reasonable formula. Raw materials are preferably selected by scientifically proportioning the formula of nitrogen, phosphorus and potassium, and the special fertilizer is developed. The special fertilizer is utilized on the basis of a seed fertilizer and is light and easy to realize, and the problem of blind fertilizer application in the period of duration of milk vetch is solved; and the agricultural production cost is lowered by applying the special fertilizer for milk vetch, the milk vetch fresh grass output is improved and increased, the economic benefit and ecological benefit can be effectively improved, and the special fertilizer has larger application and popularization values.
Description
Technical field
The invention belongs to agriculture field, be specifically related to a kind of Herba Astragali Melilotoidis (Herba Astragali Sinici) special fertilizer formula and application method thereof.
Background technology
Herba Astragali Melilotoidis (Herba Astragali Sinici) is the main green manure crop of China, at fertilizing soil, improve environment, improve agricultural output and quality, aspects such as minimizing chemical fertilizer input, carbon fixation and emission reduction are bringing into play important effect.The south maritime provinces, winter, the photo-thermal aboundresources reached 3,000,000 mu as Fujian Province's field area in annual available winter slack, and development winter kind Herba Astragali Melilotoidis (Herba Astragali Sinici) has a high potential.The bright careless output of current raising Herba Astragali Melilotoidis (Herba Astragali Sinici) has realistic meanings, and the bright careless amount of high yield can realize 1hm on the one hand
2Fertile 2 hm in field
2The target on ground, the area thereby foster and apply fertilizer in the increase rice field, on the other hand, along with the expansion of various places Herba Astragali Melilotoidis (Herba Astragali Sinici) popularizing area, Herba Astragali Melilotoidis (Herba Astragali Sinici) seed market value goes up very fast, uses high-yield culture technique and can suitably reduce application rate, thereby reduce agriculture production cost.But Dao Qu Herba Astragali Melilotoidis (Herba Astragali Sinici) bright grass production in Fujian is mainly based on the fertilizer of dressing seed, and how the later stage topdresses then comparatively blindly, how based on simple substance fertilizer such as urea, lacks the special-purpose fertilizer that produces at bright natural plant height.
Summary of the invention
In order to address the above problem, the invention provides special-purpose fertilizer of a kind of Herba Astragali Melilotoidis (Herba Astragali Sinici) and application method thereof, this fertilizer ratio science, nitrogen-high phosphorus in the employing-low potassium prescription, prepared fertilizer is fit to the growth of Herba Astragali Melilotoidis (Herba Astragali Sinici), has significant effect.
The present invention is achieved through the following technical solutions:
The special-purpose fertilizer of a kind of Herba Astragali Melilotoidis (Herba Astragali Sinici) passes through compound granulation, N:P in proportion with nitrogen phosphorus potassium simple substance raw material

Described special-purpose fertile raw material comprises: urea, diammonium phosphate, Repone K and ground dolomite, its mass fraction is: 7.9 parts～8.8 parts in urea, 32.4 parts～34.5 parts of diammonium phosphate, 11.7 parts～13.3 parts in Repone K, 43.4 parts～48 parts of ground dolomites.
The special-purpose fertile application method of Herba Astragali Melilotoidis (Herba Astragali Sinici) is to use in seedling stage, uses the special-purpose fertile 20-25kg of Herba Astragali Melilotoidis (Herba Astragali Sinici) for every mu, and the later stage does not refertilize.
Major advantage of the present invention is: one, be rich in new meaning, reasonable in design, and special-purpose fertile by enriching in seedling stage, solved blindly problem of Herba Astragali Melilotoidis (Herba Astragali Sinici) fertilising breeding time, and light simple and easy row; Two, special-purpose fertile by using Herba Astragali Melilotoidis (Herba Astragali Sinici), reduce agriculture production cost, and improved the bright careless output of increase Herba Astragali Melilotoidis (Herba Astragali Sinici), effectively increased economic benefit and ecological benefits, have bigger application and popularization value.
