preparation example Construction

[0038] The present invention also provides a preparation method of the blueberry cultivation substrate improver described in the above-mentioned technical scheme, comprising the following steps:

[0039] (1) mixing sulfur with the organic material according to the mass-to-volume ratio described in the above-mentioned technical scheme to obtain the fermentation raw material;

[0040] (2) inoculating the EM fermentation broth into the fermentation raw material to obtain a fermentation mixture, the moisture content of the fermentation mixture is 40% to 60%;

[0041] (3) performing aerobic fermentation on the fermentation mixture at a temperature of 25-35°C to obtain an aerobic fermented product;

[0042] (4) Anaerobically fermenting the aerobic fermented product under the condition of 25-35° C. to obtain a blueberry cultivation substrate improver.

[0043]The present invention mixes the sulfur and organic materials in the raw materials of the blueberry cultivation substrate impr...

Embodiment 1

[0056] In parts by weight, get 20 parts of cow dung, 20 parts of sheep manure, 40 parts of mushroom dregs, 10 parts of rice husk, 5 parts of sawdust and 5 parts of pine bark scraps and mix them to obtain organic materials. According to the quality of sulfur and the volume of organic materials than 0.5kg:1m 3 The ratio is mixed to obtain the first mixture. The mushroom dregs of shiitake mushrooms are from Fujian, mainly composed of sawdust and cottonseed hulls, and have a pH of 6.0. The rice husk, sawdust, and pine bark are first pulverized to a particle size of 5 mm and then mixed.

[0057] Take commercially available EM bacterial liquid, brown sugar and water in a ratio of 1:1:33 and mix to obtain EM fermentation liquid. The EM fermentation broth and the first mixture are sprayed on the surface of the first mixture according to the mass ratio of 1000:35, and 40 parts by weight of water are added to obtain a fermentation mixture with a water content of 40-60%.

Embodiment 2

[0063] In parts by weight, get 40 parts of cow dung, 40 parts of Flammulina velutipes slag, 15 parts of rice husk and 5 parts of sawdust and mix to obtain organic material, according to the quality of sulfur and organic material volume ratio 1kg:1m 3 The ratio is mixed to obtain the first mixture. The sawdust is pulverized to a particle size of 3mm before mixing.

[0064] Take commercially available EM bacterial liquid, brown sugar and water in a ratio of 0.8:0.8:35 and mix to obtain EM fermentation liquid. The EM fermentation broth and the first mixture are sprayed on the surface of the first mixture according to the mass ratio of 800:32, and 20 parts by weight of water are added to obtain a fermentation mixture with a water content of 40-60%.

[0065] Stack the fermentation mixture into a stack with a height of 1.0-1.5m, and carry out aerobic fermentation at 25-35°C. When the temperature of the fermentation mixture reaches 40-50°C, roll over the material and re-stack it int...

Abstract

The invention provides a blueberry cultivation medium modifier. Fermentation raw materials of the modifier include sulfur and organic materials such as farm manure, mushroom dregs and plant debris. The blueberry cultivation medium modifier is reasonable in raw material preparation, the pH (potential of hydrogen) value of the blueberry cultivation medium modifier prepared by fermentation ranges from 4.7 to 5.5, water-holding capacity is 200-250%, the content of organic matters is 45-65%, and volume weight is 2.0g / cm<3>. The blueberry cultivation medium modifier serving as a soil modifier can increase soil organic matters, improve soil structures, loosen soil, promote root system development and keep water and nutrients in the soil, and the modified soil can meet the requirements of blueberry growth and development. When the blueberry cultivation medium modifier serves as a blueberry cultivation soil modifier, cost is about 1500 Yuan per mu and greatly reduced.

Description

technical field [0001] The invention relates to the technical field of blueberry cultivation, in particular to a blueberry cultivation substrate improver and its preparation method and application. Background technique [0002] In recent years, with the improvement of people's living standards, the diversification requirements of the fruit market and people's understanding of natural fruits with key nutrients, blueberries, as a new, healthy and high-growing fruit, have developed rapidly in my country. Promoting blueberry as a new tree species to adjust the agricultural planting structure has a very broad prospect for development. [0003] However, blueberry has higher requirements on cultivation soil. Compared with other perennial fruit trees, blueberry has many and slender root systems without root hairs, and most of them are concentrated near the soil surface (5-20cm soil layer). Therefore, blueberries with good growth and yield have special requirements for soil condition...
