Problems solved by technology

[0003] The site conditions for the production of high-quality chestnuts are low mountain and hilly areas, and the quality of Jingdong chestnuts is the best. The soil parent materials in this area are mostly loose parent rocks such as gneiss and granite. Loose but high gravel content, good permeability but low soil fertility, especially low soil organic matter, resulting in low soil fertilizer supply capacity and poor water retention and fertility
For a long time, the management of soil, fertilizer and water in traditional chestnut production has been extensive. With the introduction of new varieties and the popularization and application of dense planting cultivation techniques in recent years, chestnut empty canopy has become the main problem that limits the yield of chestnuts. Therefore, it is urgent to solve scientific fertilization technology for high-yield and high-quality chestnuts. Problems, in production, it is more necessary to materialize chestnut scientific fertilization technology into a series of catering chestnut special fertilizers

Embodiment 1

[0016] Embodiment 1 A kind of preparation of the organic fertilizer that reduces chestnut emptying rate, comprises the following steps:

[0017] (1) Cow dung fermentation

[0018] Dry the fresh cow dung cleared from the cattle farm to a water content of 65% to 75%, inoculate enzyme bacteria according to 0.3% of the fresh weight of the mixed material, one layer of cow dung and one layer of bacterial powder, mix well and build a heap for fermentation. When the hyphae appear in the pile, start to turn the pile, control the temperature of the center of the pile to not exceed 65°C, turn over once every 2-3 days in summer, and the fermentation time is about 10 days. The organic matter content of the obtained decomposed cow dung is generally 30% to 37.5%, N+P 2 o 5 +K 2 The total amount of O is 3% to 4%;

[0019] (2) Preparation of vermicompost

[0020] Use decomposed cow dung to feed earthworms to produce vermicompost. The stacking location should be between the trees or in the...

Embodiment 2

[0024] Embodiment 2 A preparation of an organic fertilizer (base fertilizer) that reduces the chestnut emptying rate, comprising the following steps:

[0025] (1) Cow dung fermentation

[0026] Dry the fresh cow dung cleared from the cattle farm to a water content of 65% to 75%, inoculate enzyme bacteria according to 0.1% to 0.7% of the fresh weight of the mixed material, one layer of cow dung and one layer of bacteria powder, mix well and build a heap for fermentation , when the mycelium appears in the stack, start to turn the pile, and control the temperature of the center of the pile to not exceed 65°C. Generally, turn it once every 2-3 days in summer, and once every 4-10 days in spring and autumn. 45 days, in winter in the north, it needs to be covered with black plastic or corn stalks to keep warm. The organic matter content of the obtained decomposed cow dung is generally 30% to 37.5%, N+P 2 o 5 +K 2 The total amount of O is 3% to 4%;

Abstract

The invention discloses a preparation method of a series organic fertilizer for reducing the empty rate of Chinese chestnuts. Poultry excrement and wormcast are used as main materials, and a certain quantity of nitrogen, phosphorus, potassium, zinc and boron nutrients are coordinated with the main material to prepare the special fertilizer for Chinese chestnuts. The fertilizer is capable of obviously reducing the empty rate of Chinese chestnuts and the spider mite infection rate of chestnut trees and promoting the root development of chestnut trees. According to the nutrient demands of Chinese chestnuts in different growth periods, the catering type series special fertilizer for Chinese chestnuts is formed, the problem of unscientific fertilization of Chinese chestnuts is solved, and the problems that unscientifically treated poultry excrement is capable of polluting the environment and nutrient sources are wasted are synchronously solved. Compared with conventional fertilization, the application of the series special organic fertilizer for Chinese chestnuts enables the empty rate of Chinese chestnuts to be reduced by more than 60% and the yield of Chinese chestnuts to be increased by more than 30%, and can achieve the remarkable synergism.

Description

[0001] technical field [0002] The invention relates to an organic fertilizer for improving the yield and quality of dry fruits such as chestnuts and walnuts, in particular to a preparation method of the organic fertilizer for reducing the empty space rate of chestnuts. Background technique [0003] The site conditions for the production of high-quality chestnuts are low mountain and hilly areas, and the quality of Jingdong chestnuts is the best. The soil parent materials in this area are mostly loose parent rocks such as gneiss and granite. Loose but high gravel content, good permeability but low soil fertility, especially low soil organic matter, resulting in low soil fertilizer supply capacity and poor water retention and fertility. For a long time, the management of soil, fertilizer and water in traditional chestnut production has been extensive. With the introduction of new varieties and the popularization and application of dense planting cultivation techniques in rec...
