A kind of planting and mowing method of forage-type low-phenol cotton

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 ...

Problems solved by technology

[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
