Description
Technical Field
The invention belongs to the technical field of cotton planting devices, and particularly relates to a mulching film recovery device suitable for cotton interlines during fertility.
Background
The important function of the plastic film mulching of the cotton is to improve the ground temperature and a series of changes brought by the ground temperature, and mainly improve the ground temperature of the seeds in the sprouting and seedling emergence period and the Miao Lei period, because the ground temperature is lower in the early period of sowing and growing (except for the southern cotton), the ground temperature is improved by covering the plastic film, the sprouting, seedling emergence period and the strong growth of the seeds in the seedling period are promoted, and early bud, early flowering and early fruiting are promoted, so that the flowering and fruiting periods of cotton plants are coordinated with the local high temperature, rich illumination and environmental dominant periods, namely the flowering and fruiting period is regulated in the optimal period of local climate, and the high quality, high yield and high efficiency of the cotton are realized, which is the important meaning of the plastic film mulching of the cotton.
Production practice proves that under the condition of cotton field production, the mulching film is covered at a stage from sowing to the lower temperature of the bud stage, the ground temperature can be increased, the growth and development of cotton plants are promoted, and after Cheng Lei flowers are grown, the ground temperature is increased along with the increase of the air temperature, even if the mulching film is not covered, the ground temperature is sufficient at the moment and the normal growth and development needs of cotton are met, after that, the heating effect of the mulching film is towards the end, the heating and early-promoting effect like the earlier stage is lost, and even negative effects can occur, such as shallow soil penetration of root systems of cotton plants, small water and fertilizer absorption range, low lodging resistance and the like are caused.
The agricultural mulching film is a high molecular hydrocarbon (polyvinyl chloride) prepared from polyethylene and an antioxidant (an ultraviolet resistant material), has the characteristics of large molecular weight, stable performance and the like, is difficult to photodecomposition and thermally degrade under natural conditions, is difficult to degrade in a biological mode such as bacteria and enzymes, can remain in soil for a long time, and a large amount of residual mulching film damages the soil structure, so that the soil permeability and the soil porosity are gradually reduced, further the migration of water fertilizer in the soil is influenced, the microbial activity of the soil and the formation of the normal structure of the soil are influenced, the soil fertility is reduced, and the living condition of plants is deteriorated; the residual mulching film has higher toughness and ductility, plant roots are difficult to penetrate, so that the root growth is difficult, the growth and development of crops are affected, and the crop yield is reduced. In addition, the mulch film residue also brings a series of other negative effects, such as harmful gas generated by burning the mulch film residue, and the seeding and mechanical quality reduction caused by influencing farmland mechanical farming operation.
