Description
Technical field
The present invention relates to a kind of preparation method, in particular to a kind of release and release control fertilizer preparation method for winter peach is related to controlling
Technical field of fertilizer manufacture processed.
Background technique
Winter peach, a kind for peach, peach are one of the main fruit major class in China, and much later is listed in summer and autumn maturation,
This kind is picked in severe winter and is listed, sweet clear and melodious and famous with the small meat tenderness of core, is curiosa in rare and precious peach, and feedback
The good merchantable brand of friends and guests good friend, winter peach, also known as Chinese winter peach, snow peach are given, is the pole late variety in peach class fruit, the sea of suitable growth
Range is pulled out between 1500-2300m, between 10 DEG C -18 DEG C of average annual temperature, the area of average annual rainfall 700-1300mm, especially
It is suitable for blooming January in purple soil, the gentle slope of yellow earth, hills and the preferable regional culture plantation of drainage condition, winter peach,
November is mature, and growth period is extremely long, and since geographical conditions are superior, day and night temperature is big, and illumination is sufficient, and winter peach nutrient accumulation is abundant,
Sugar content is high, crisp and sweet, the small meat tenderness of the big core of fruit, delicious uniqueness, and storage endurance, and great competitiveness, feature is: a big, crisp sweet tea,
Late-maturing, high yield, shelf-stable, it is high-quality: appearance blush, pulp clear and melodious time sweet, excellent taste, freestone, sugariness it is high: sugar content
15% reaches as high as 18%, and late-maturing: the first tenday period of a month in October to mid-November is mature, and the maturity period, high yield: plant trees this year hung next year very late
Fruit, every plant 5 kilograms to 10 kilograms, with regard to more than 3000 jin, however in the production of existing winter peach, release and release control fertilizer preparation is inaccurate for next year per mu yield
Really, cause fertilizer to be unable to reach maximum validation, be easy to cause the wasting of resources.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the existing defects, provides a kind of release and release control fertilizer preparation for winter peach
Method.
In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions:
