Problems solved by technology

[0004] During the cotton planting process, under soil cultivation conditions, the cotyledons of the germinated cotton seedlings are wrapped by the cotton seed shell, and the cotton seeds are protected by the shell very hard. In a dry environment, the cotton shell quickly loses water and becomes hard, unable to fall off , causing cotton seedling growth to be affected
The usual method is manual peeling. However, the newly unearthed cotton seedlings are very tender. The consequence of manual peeling is that the leaves of some seedlings are torn, which will also affect the growth and development of the seedlings. In addition, because the cotton seedlings are small and young Tender, manual peeling is time-consuming and labor-intensive
In addition, the cotton seed shell is hard, resulting in a low germination rate of cotton seedlings, and some seeds will not sprout after sowing

Embodiment 1

[0034] 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:

[0035] a. Preparation of soaking solution

[0036] Glycerol and water are mixed evenly according to the ratio of glycerol by volume: water=0.8:100;

[0037] b. Seed soaking

[0038] Get 300 cotton 24 seeds without sulfuric acid delinting,

[0039] 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.

[0040] c. Planting cotton seeds

[0041] The soaked cotton seeds are planted in the cotton field, and then routinely managed in the field;

[0042] d. Prepare shelling solution

[0043] 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

[0048] 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.

[0049] 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:

[0050] Table 1

[0051] Final emergence rate (%) Emergence period (d) (50% of the seedlings eme...

Embodiment 2

[0056] 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:

[0057] a. Preparation of soaking solution

[0058] Glycerol and water are mixed evenly according to the volume ratio of glycerol: water=1:100;

[0059] b. Seed soaking

[0060] Get 300 cotton 24 seeds after sulfuric acid develvet,

[0061] 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.

[0062] c. Planting cotton seeds

[0063] The soaked cotton seeds are planted in the cotton field, and then routinely managed in the field;

[0064] d. Prepare shelling solution

[0065] 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...

Abstract

The invention provides a method for accelerating shelling of cotton seedlings. The method comprises the following steps: a, preparing of a soaking solution; b, soaking of seeds; c, planting of cotton seeds; d, preparing of a shelling solution; e, shelling of the cotton seedlings. The method is characterized by soaking the cotton seeds in a glycerin water solution for a certain time before planting cotton, then planting the soaked cotton seeds, and spraying the cotton seedlings with cotton shells by using the glycerin water solution containing polysorbate 20 after bursting out of earth, thus removing the cotton shells within a shorter time. The method provided by the invention is simple, is easy to master and cannot damage cotton; meanwhile, the seedling emergence stage of the cotton seeds is shortened; dwarf of cotton plants is promoted to a certain degree; meanwhile, the seedling emergence rate of the cotton seeds is increased.

Description

Technical field: [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for accelerating shelling of cotton seedlings during cotton planting. Background technique: [0002] Crop chemical control cultivation engineering has become an important direction of crop cultivation research and has been vigorously developed. It is a new way for China's agriculture to reach a new level, and it is an important symbol of the development of modern agricultural science and technology. The vast number of scientific and technological workers in China have successively proposed chemical control cultivation projects for crops such as cotton, rapeseed, rice, wheat, and corn, and entered into practice. One of the more typical ones is the system chemical control technology proposed by the Crop Chemical Control Center of China Agricultural University to use DPC to regulate the life of cotton. [0003] As one of the important economic crops,...
