Method for accelerating shelling of cotton seedlings
A technology for seedlings and cotton, which is applied in the field of accelerating the shelling of cotton seedlings. It can solve the problems of affecting the growth and development of seedlings, the tearing of seedling leaves, and the low germination rate of cotton seedlings, so as to delay the time of dryness and death, promote dwarfing, and improve seedling emergence. rate effect

Embodiment 1
[0037] The present embodiment takes Zhongmian 24 as an example, Zhongmian 24 accelerates the shelling of cotton seedlings in the planting process, and a method for accelerating the shelling of cotton seedlings comprises the following steps:
[0038] a. Preparation of soaking solution
[0039] Glycerol and water are mixed evenly according to the ratio of glycerol by volume: water=0.8:100;
[0040] b. Seed soaking
[0041] Get 300 cotton 24 seeds without sulfuric acid delinting,
[0042] Soak 300 medium cotton 24 seeds in eg 100mL soaking solution, and then place the soaking solution with cotton seeds in an environment of 40° C. for 3 hours.
[0043] c. Planting cotton seeds
[0044] The soaked cotton seeds are planted in the cotton field, and then routinely managed in the field;
[0045] d. Prepare shelling solution
[0046] Glycerin, Tween 20 and water are mixed evenly according to the ratio of glycerol: Tween 20: water=1:0.1:100 according to the volume ratio; step d, in ...
Embodiment 1
[0051] Observing the cotton seedlings of Example 1 and Comparative Example 1 cotton seedlings, it was found that about 98% of the cotton seedlings with cotton husks in Example 1 had cotton husks coming off within 3 hours after the shelling liquid was sprayed, while the cotyledons of cotton seedlings were intact , growing normally. In Comparative Example 1, about 90% of the cotton seedlings with cotton husks fell off 3 days after the cotton seedlings were unearthed, and the cotyledon growth of some cotton seedlings was poor. It can be known that the present invention can effectively accelerate the shelling of cotton seedlings.
[0052] Observe embodiment 1 cotton seedling and comparative embodiment 1 cotton seedling, contrast both the emergence rate, emergence stage and the following length of cotton seedling cotyledon node, comparative result is as shown in table 1:
[0053] Table 1
[0054] Final emergence rate (%) Emergence period (d) (50% of the seedlings eme...
Embodiment 2
[0059] Repeat Example 1, with the following differences. The cotton seeds used in this example are the cotton seeds of Zhongmian 24 after delinting with sulfuric acid. The specific implementation steps are as follows:
[0060] a. Preparation of soaking solution
[0061] Glycerol and water are mixed evenly according to the volume ratio of glycerol: water=1:100;
[0062] b. Seed soaking
[0063] Get 300 cotton 24 seeds after sulfuric acid develvet,
[0064] Soak 300 cotton 24 seeds delinted with sulfuric acid in 100 mL soaking solution, and then place the soaking solution with cotton seeds in an environment of 40° C. for 4 hours.
[0065] c. Planting cotton seeds
[0066] The soaked cotton seeds are planted in the cotton field, and then routinely managed in the field;
[0067] d. Prepare shelling solution
[0068] Glycerol, Tween 20 and water are mixed evenly according to the ratio of glycerol: Tween 20: water=1.5:0.1:100 according to the volume ratio; step d, in preparing...
