Dedicated composite fertilizer, microfertilizer for medlar and its application method

Abstract

The invention discloses four specific composite fertilizers of matrimony vine and four liquid micro-fertilizers and mating fertilizing technique, which comprises the following steps: adopting aquacare, double super phosphate of lime and potassium sulfate as raw material; preparing four specific composite fertilizers of matrimony vine with different proportion of N, P and K; utilizing aquacare, KH2PO4, K2SO4, EDTA, CuSO4, ZnSO4, MnSO4, FeSO4, ammonium molybdate, methionine, sodium humic acid, borax, sodium selenite and rare earth nitrate as raw material to prepare the product.

Description

technical field [0001] The invention relates to four special compound fertilizers for wolfberry, four special micro-fertilizers for wolfberry and matching application methods thereof. technical background [0002] Lycium barbarum is a kind of perennial woody medicinal economic crop with special fertilizer tolerance. The annual growth period is long. From mid-April to early November, it experiences important processes such as flower bud differentiation, branch and leaf growth, flowering and fruiting, and root system growth. Each process consumes a lot of nutrients, and some physiological processes overlap, such as The growth of branches and leaves, the differentiation of flower buds, flowering, the growth of young fruits, and the ripening of fruits are staggered and continuous, which is completely different from the situation of other fruit trees with one flower and one fruit in a year. Therefore, they need more nutrients and need fertilizer for a long time. If the nutrient ...

Problems solved by technology

[0005] At present, there are many kinds of compound fertilizers and micro-fertilizers on the market, but they lack pertinence, especially the research on the nutrition, growth, growth phenomena and fertilization technology of Lycium barbarum, a crop with distinct regional characteristics and special growth and reproduction characteristics. There are not many, the fertilizer products developed are single, the nutrition is not comprehensive, and there is no supporting and systematic fertilization technology for guidance, which cannot meet the nutritional needs of wolfberry

The Chinese patent No. 200510065339.0, titled "Preparation of special fertilizer for wolfberry and its fertilization technology", discloses three special compound fertilizers for wolfberry, a micro-fertilizer and related application methods. This patented technology ignores the nutritional needs of wolfberry in the early stage , and this period is an important stage for the flowering and fruiting of old eye branches, spring seven-inch growth, flower bud differentiation, and flowering and fruiting. Neglecting the fertilizer supply at this stage will seriously affect the quality of summer fruit at the time of picking and the annual output of wolfberry.
