Embodiment 1
[0041] 0.05% of salinity-tolerant Trichoderma harzianum, 0.5% of Bacillus thuringiensis, 0.05% of Streptomyces loucherii, and 40.0% of compound amino acids are added into a mixer according to the components and mixed evenly to obtain a "first material".
[0042] The biochemical potassium humate 38%, ammonium metaphosphate 5.0%, amino acid zinc 1.5%, boric acid 1.2%, 4-aminobutyric acid 0.05%, chitosan 0.08% and the rest of the amino acids were mixed uniformly according to the components to obtain "No. two materials".
[0043] The "first material" is added to the "second material", fully stirred, and evenly mixed to obtain a multi-effect nutritional composition for cotton seedlings in saline-alkali land.
[0044] When the seedling water is dripped after the cotton seeds are sown, 1.0 kg of the composition is used per 667 square meters, and it is applied along with the dripping of the seedling water.
Embodiment 2
[0046] 0.08% of salinity-tolerant Trichoderma harzianum, 0.6% of Bacillus thuringiensis, 0.10% of Streptomyces loucherii, and 45.0% of compound amino acids are added to the mixer according to the components and mixed evenly to obtain the "first material".
[0047] 35% of biochemical potassium humate, 5.50% of ammonium metaphosphate, 2.0% of zinc amino acid, 1.5% of boric acid, 0.06% of 4-aminobutyric acid, 0.09% of chitosan and the rest of the amino acids were mixed uniformly according to the components to obtain "No. two materials".
[0048] The "first material" is added to the "second material", fully stirred, and evenly mixed to obtain a multi-effect nutritional composition for cotton seedlings in saline-alkali land.
[0049] Use 3.0 kg of the composition per 667 square meters of ground, spread evenly on the ground before sowing cotton, and sow cotton after sowing.
Embodiment 3
[0051] 0.10% of salinity-resistant Trichoderma harzianum, 0.7% of Bacillus thuringiensis, 0.15% of Streptomyces loucherii, and 50.0% of compound amino acids are added to the mixer according to the components and mixed evenly to obtain the "first material".
[0052] 30% of biochemical potassium humate, 6.0% of ammonium metaphosphate, 2.5% of zinc amino acid, 1.8% of boric acid, 0.07% of 4-aminobutyric acid, 0.10% of chitosan and the rest of the amino acids were mixed uniformly according to the components to obtain "No. two materials".
[0053] The "first material" is added to the "second material", fully stirred, and evenly mixed to obtain a multi-effect nutritional composition for cotton seedlings in saline-alkali land.
[0054] When the seedling water is dripped after the cotton seeds are sown, 1.5 kg of the composition is used per 667 square meters, and it is applied along with the dripping of the seedling water.
