Embodiment 1
[0035] A kind of method of screening drought-tolerant soybean variety of embodiment 1, comprises the steps:
[0036] (1) Crush corn stalks and bones, then mix them according to the weight ratio of corn stalks, decomposed cow dung, rice husk, bone residue, slag and vermicompost 1:3.5:1.5:1.5:2.5:4.5, and then mix the mixture with multi-bacteria The spirit is mixed according to the ratio of 10L:0.8g, and fermented and decomposed to obtain an organic ecological cultivation substrate. The organic ecological cultivation matrix is used without deliberate pressing and compaction. The physical and chemical properties of the matrix are as follows: the bulk density is 0.77g / cm 3, the total porosity is 76%, the ventilation pores are 16%, the water-holding pores are 60%, the pH value is 6.6, the conductivity is 3.49m s / cm, and the cation exchange capacity is 64c mol / kg.
[0037] (2) Select soybean seeds of three varieties A, B, and C with full and uniform grains and no disease, and sow...
Embodiment 2
[0046] A kind of method of screening drought-tolerant soybean variety of embodiment 2, comprises the steps:
[0047] (1) Crush corn stalks and bones, then mix them according to the weight ratio of corn stalks, decomposed cow dung, rice husk, bone residue, slag and vermicompost 1:4.5:0.5:2.5:1.5:5.5, and then mix the mixture with multi-bacteria The spirit is mixed according to the ratio of 10L: 1.2g, and fermented and decomposed to obtain an organic ecological cultivation substrate. The organic ecological cultivation matrix is used without deliberate pressing and compaction. The physical and chemical properties of the matrix are as follows: the bulk density is 0.79g / cm 3 , the total porosity is 78%, the ventilation pores are 18%, the water-holding pores are 62%, the pH value is 6.4, the conductivity is 3.57m s / cm, and the cation exchange capacity is 61c mol / kg.
[0048] (2) Select soybean seeds of three varieties A, B, and C with full and uniform grains and no disease, and s...
Embodiment 3
[0057] A kind of method of screening drought-tolerant soybean variety of embodiment 3, comprises the steps:
[0058] (1) Crush the corn stalks and bones, then mix them according to the weight ratio of corn stalks, decomposed cow dung, rice husk, bone residue, slag and vermicompost 1:4:1:2:2:5, and then mix the mixture with multi-bacteria Ling is mixed according to the ratio of 10L: 1g, and fermented and decomposed to obtain an organic ecological cultivation substrate. The organic ecological cultivation matrix is used without deliberate pressing and compaction. The physical and chemical properties of the matrix are as follows: the bulk density is 0.71g / cm 3 , the total porosity is 77%, the ventilation pores are 14%, the water-holding pores are 61%, the pH value is 6.2, the conductivity is 3.44m s / cm, and the cation exchange capacity is 69c mol / kg.
[0059] (2) Select soybean seeds of three varieties A, B, and C with full and uniform grains and no disease, and sow one soybean...
