[0004] Since the introduction of low-phenol cotton resources in my country in the 1970s, the research work on low-phenol cotton has been carried out successively. According to the research, low-phenol cotton has been developed as feed, food, medicine, etc., but there is no research on planting a low-phenol cotton, whose branches, leaves and stems are directly used as forage grass, and the existing technology is to use low-phenol cotton After the cotton is harvested, the cotton plants are crushed and used as feed, which is not only of poor quality, but also has poor palatability

Embodiment 1
[0037] A method for planting and mowing grass-type low-phenol cotton comprises the following steps:
[0038] S11. Straw returning to the field: After harvesting the previous crop, crush the straw to a length of ≤10cm, spread it evenly in the field, and plow the straw into the soil to a depth of ≥25cm;
[0039] S12, base fertilizer treatment: apply 1.5 tons of base fertilizer per mu, and the base fertilizer is composed of the following components in parts by weight: 100 parts of pastoral soil, 100 parts of decomposed cattle and sheep manure, 80 parts of cottonseed cake, 10 parts of nitrogen, phosphorus and potassium compound fertilizer, and 10 parts of tea residue , 1 part orange peel, 1 part cellulolytic enzyme;
[0040] The above components are mixed, stacked and decomposed, and then crushed to make granular fertilizer, plowed into the soil, and the plowing depth is 20-25cm;
[0041] S13. Soil preparation to create entropy: turn up the field before winter, and irrigate to cr...
Embodiment 2
[0050] A method for planting and mowing grass-type low-phenol cotton comprises the following steps:
[0051] Change the mowing period in Step S7 of Example 1 to the flowering and boll period to boll opening period, and harvest 5 times, and the remaining steps are the same as in Example 1.
Embodiment 3
[0053] A method for planting and mowing grass-type low-phenol cotton comprises the following steps:
[0054] Change the mowing period of Step S7 in Example 1 to the boll opening period, and harvest the aboveground cotton plants at one time, and the remaining steps are the same as in Example 1.

Abstract
The invention belongs to the technical field of cotton planting, and provides a forage type low-gossypol cotton planting and mowing method. According to the present invention, the results of the fieldexperiments in the cotton areas of the middle and south area of Hebei province determine that the optimal planting density is 8000 plants / mu, the mowing period is from the flowering and boll-formingstage to the boll opening stage, the mowing period is divided in five mowing, the mowing position is the top third leaf, more than 3000 kg of fresh low-gossypol cotton branches and leaves can be harvested per mu according to the planting method, and the branches, the leaves and the stems of the mowed low-gossypol cotton can be directly fed to cattle and sheep after being crushed; the invention further provides a supporting technical measure adopted in a forage type low-gossypol cotton planting process, wherein the supporting technical measure comprises: land preparation, base fertilizer treatment, variety selection, rogueing, special cultivation management and the like; and through the scientific and reasonable planting and mowing method, the problem of poor palatability in the applicationof the branches, the leaves and the stems of the low-gossypol cotton planted by using the prior art as the feed is solved, the utilization value of the low-gossypol cotton branch-leaf-stem is effectively improved, and the new cotton planting utilization mode mainly as the feed is created.
Description
technical field [0001] The invention belongs to the technical field of cotton planting, and relates to a method for planting and cutting grass-type low-phenol cotton. Background technique [0002] At present, cotton is an important economic crop and occupies an important position in the world and my country's national economy. For a long time, in addition to the effective use of cotton fiber, a large part of the nutrients such as protein in cotton plants and seeds have been abandoned. The reason for this is that ordinary cotton contains gossypol, a substance that is toxic to humans and other living things. [0003] Low-phenol cotton, also known as "non-toxic cotton", differs from ordinary cotton in that the content of free gossypol in its various tissues and organs is low. Free gossypol is a phenolic derivative that is toxic to humans, animals and other organisms. The content of this toxic substance in common cotton varieties is about 1%. Studies have shown that with the ...
