It mixes uniformly, and biogas slurry and the weight ratio of warm water are 1：2, the temperature of warm water is 35-45 degrees Celsius, and the cultivation equipped with cottonseed is held
Device moves to position on the sunny side and is placed, and all needs to be mixed to cultivating the cottonseed in container daily；
S7, after above-mentioned cottonseed grows seedling, be drawn off, and choose excellent soil as garden, to the cotton after breeding
Seed carries out culture transferring.
2. the breeding method of cold-resistant cotton according to claim 1, which is characterized in that the seedling soil on garden ground needs to keep in S7
Moistening, and build arched shed with hyaline membrane above it and kept the temperature, there are capping thin film or straw, anti-seedling when frost to endure cold.
3. the breeding method of cold-resistant cotton according to claim 1, which is characterized in that ionized water in S4 be calcium from
The mixture of son, carbon, phosphonium ion, potassium ion, water, and the weight ratio of calcium ion, phosphonium ion, potassium ion, sodium ion, water is
1：1：0.5：0.5：2.
4. a kind of cold-resistant conditioning agent according to claim 1, which is characterized in that the weight ratio of ingredient is：
4-7 parts of sea grass polysaccharide, 8-15 parts of salicylic acid, 3-7 parts of potassium dihydrogen phosphate, 3-7 parts of ascorbic acid, 3-7 parts of fulvic acid, beet
8-15 parts of alkali, 2-5 parts of spermidine, 2-5 parts of surfactant.
5. cold-resistant conditioning agent according to claim 4, which is characterized in that specifically the optimum weight percent of ingredient is：
5 parts of sea grass polysaccharide, 12 parts of salicylic acid, 5 parts of potassium dihydrogen phosphate, 5 parts of ascorbic acid, 5 parts of fulvic acid, 12 parts of glycine betaine, Asia
4 parts of spermine, 4 parts of surfactant.
6. the breeding method of cold-resistant cotton according to claim 1, which is characterized in that the addition nutrient solution in S4 is solid
Nitrogen bacterium, proline, potassium nitrate, potassium iodide mixture, and nitrogen-fixing bacteria, proline, potassium nitrate, potassium iodide weight ratio be 1：
0.5：0.5：1.
