Embodiment 1

[0027] Example 1: The method of quickly returning straw to the field for fertilizer fertilizer

[0028] The present invention provides a method for quickly returning straw to the field for bacterial fertilizer. The main steps are:

[0029] Crush the wheat stalks to a length of 60 mesh ~ 10cm for use;

[0030] 1) The activated Trichoderma ( Trichoderma asperellum ) Strain T-A158 (activation step: use a 30mm diameter punch on the Trichoderma plate that has been cultured for 2 days to take a bacterial cake on the outer edge of the colony, inoculate it in the center of the PDA plate, and cultivate it at a constant temperature of 28°C Cultivate in the box until the green spores cover the whole plate) Dissolve in sterile distilled water to obtain the spore aqueous solution of Trichoderma aculeatus strain T-A158, the spore content is 0.58×10 10 ~1.071×10 10 Pcs / ml, keep in refrigerator at 4℃ for later use;

[0031] 2) Put into a 120L fermentation medium-containing strain fermentation tank, a...

[0040] Example 2 Analysis of Fertilizer Effect of Quick Straw Return to Field-Wheat Planting 2016.10-9-2017

[0041] The fertility analysis experiment of fast returning straw to the field was conducted in the experimental field of Zhoukou Normal University. Wheat was planted on the land where the straw was returned to the field, and was divided into an experimental group and a control group. The experimental group was the soil where the straw was quickly returned to the field in Example 1, and the control group was the traditional soil where the straw was returned to the field. Soil), the control group and the experimental group wheat planting time are 17 days after returning the straw to the field. After the wheat is planted for 5 months, observe the effect and take pictures. Compared with the control group, the wheat growth of the experimental group shows a significant difference, see image 3 .

Embodiment 3

[0042] Example 3 Analysis of Fertilizer Effect of Quick Return of Straws to Field-Kale Cultivation 2018.March 9-March 19, 2018

[0043] The fertilizer efficiency analysis experiment of the rapid return of straw to the field was carried out in Xiangyao Ecological Park, Zhoukou City. Kale was planted on the land where the straw was returned to the field, which was divided into an experimental group and a control group. The experimental group was the soil where the straw was quickly returned to the field in Example 1, and the control group was the traditional soil where the straw was returned to the field. Into the soil), both the control group and the experimental group kale were planted for 17 days after the straw returned to the field. After the kale was planted for 10 days, observe the effect and take pictures. Compared with the control group, the growth of the kale in the experimental group showed a significant difference, see Figure 4 .

Abstract

The invention relates to a rapid returning method for production of bacterial manure from straws. The method comprises the steps: inoculating a liquid strain fermentation tank containing a fermentation medium with a spore aqueous solution of trichoderma asperellum strain T-A158 to ferment for 7-10 days to obtain a trichoderma asperellum fermentation liquid; mixing ferrous sulfate, ammonium molybdate, and the trichoderma asperellum fermentation liquid to prepare a trichoderma asperellum straw decomposed solution; spraying the trichoderma asperellum straw decomposed solution containing spores 1is multiplied by 10<7> spores/mL on straws and humic acid; the dosage being 30-40L per mu, spraying water and evenly arranging a layer of straws on the top, the thickness being 7-12 cm, making the final moisture content be 40-46 percent; covering with a mulch and fermenting at room temperature for 7-20 days; then directly plowing the land for cultication. The rapid returning method provided by theinvention can effectively alleviate the occurrence of pests and diseases in a greenhouse, increase the soil fertility in the greenhouse, solve the problem of disadvantages of nowhere to place the straws and returning the straws to the field, reduce the use of the fertilizer, increase the yield of the crop, improve the quality of the crop, and improve the soil environment.

Description

Technical field [0001] The invention relates to a method for quickly returning straw to the field for bacterial fertilizer. Background technique [0002] my country is already the largest fertilizer producer in the world. Although the area of ​​arable land is less than 10% of the world's total, my country's chemical fertilizer application is close to 1 / 3 of the world's total. Excessive use of chemical fertilizers not only makes the soil nutrient single, and fertility declines rapidly, which seriously affects crop quality and pollution The loss of material damages the ecological environment, and the chemical residues endanger human health and cause great harm to agricultural production, human health and the natural environment. my country’s land has been cultivated year after year, the cultivated layer has gradually become thinner, the soil organic matter content has been decreasing year by year, and the soil has become increasingly compacted. Soil problems are the biggest proble...
