Field crop three-dimensional film mulching method and film mulching tool adopting by field crop three-dimensional film mulching method

Abstract

The invention discloses a field crop three-dimensional film mulching method, wherein according to the film mulching method, the supporting and film mulching are carried out on overground parts of crops, and a three-dimension space is formed around the crops mulched with films. The film mulching method comprises the following steps that (1) a film mulching frame cover is used for realizing the three-dimension coverage on young seedlings: a, a framework, a plastic film and a frame cover are combined, and in addition, the film mulching frame cover is obtained; b, the field transportation and the field pre-arrangement of the film mulching frame cover are carried out; c, young seedling transplanting or seeding is carried out, and in addition, the film mulching frame cover covers on the young seedlings or seeds; and d, film breaking and ventilation are carried out; and (2) the film mulching frame cover is recovered and utilized: e, the film mulching frame cover is removed in the field; and f, the plastic film on the film mulching frame cover is dismounted, in addition, the framework and the frame cover are singly recovered and placed for later use, and the plastic films are recovered for realizing the waste material utilization. The invention changes the traditional film mulching technology. The method has the advantages that the structure is simple, the use is convenient, the cost is low, the work intensity is greatly reduced, the environment is favorably protected, white pollution is reduced, the heat insulation and moisture preservation effects are good, the disease and pest protection is favorably realized, in addition, the yield of crops is increased, and the quality is improved.

Description

Technical field: [0001] The invention relates to the technical field of film covering of crops, in particular to a three-dimensional film covering method for field crops and a film covering tool thereof. Background technique: [0002] Plastic film mulching technology or plastic film mulching cultivation is to cover the ground with a transparent plastic film, sow seeds under the film and protect the growth of crop seedlings; when the temperature warms up, the film is uncovered to allow the seedlings to grow under normal climatic conditions. Since the film-covered cultivation technology was introduced from Japan in 1979, it has been popularized and applied on a large scale in more than 40 kinds of crops including tobacco in more than 30 provinces and municipalities across the country. More than 10,000 mu. Especially in high and cold regions, the effect of film mulching crops on increasing yield and quality is more significant. After years of development and application resear...

AI Technical Summary

Problems solved by technology

It is easy to press the seedlings when mulching in the former way, causing the seedling stems to bend or even break, and then die, resulting in gaps in the plants

In the latter way, the mulch film is opened, and the heat preservation effect is not good, which is not conducive to the growth of crops.

Moreover, this method of mulching often covers a ridge or an area with mulch. Once a certain plant is infected with the disease in the early stage of growth, the epidemic situation is not easy to control.

In addition, when the plastic film is taken out, the plastic film pressed by the soil block is not easy to take out, resulting in a large number of plastic film fragments in the field, causing white pollution
