Tobacco three-dimensional transplanting method based on liquid mulching film

Abstract

The invention aims to provide a tobacco three-dimensional transplanting method based on a liquid mulching film. The method includes welding a transplanting cover with 2.8mm steel wires to form a cylindrical basic frame, wrapping a 20-mesh stainless steel gauze, and forming a poison bait groove in one supporting column; according to the conventional tobacco transplanting mode, ridging and nesting and transplanting tobacco seedlings, and smashing large clods before ridging, with the optimal row spacing of 1.20m, nest spacing of 0.60m, nest opening of 0.40m and nest depth of 0.2m; covering the transplanting cover, covering the edges with fine soil, and spraying the whole ridge with the liquid mulching film added with a herbicide; and putting poison baits into the poison bait groove every 5-10tobacco seedlings. The method has the advantages that the tobacco transplanting process can not be restricted by external conditions, and the tobacco transplanting can be carried out in an environment-friendly and efficient manner.

Description

technical field [0001] The invention belongs to the technical field of tobacco planting, and relates to a three-dimensional tobacco transplanting method based on liquid plastic film. Background technique [0002] Film mulching is an agricultural cultivation technique aimed at reducing the use of pesticides, inhibiting the growth of weeds, reducing soil water loss, stabilizing soil temperature, and promoting the rapid growth of crops. At present, low-density polyethylene plastic mulch is the most widely used, but the "white pollution" formed by plastic mulch residues will pollute the soil, water quality and other environments. And when recycling, the labor cost is higher. The three-dimensional mulching technology of tobacco fields adopts the support frame method to realize the three-dimensional coverage of the crop film, that is, the rounded table-shaped frame made of steel wire or plastic with a small diameter of the upper bottom and a large diameter of the lower bottom is ...

AI Technical Summary

Problems solved by technology

At present, it is rarely used in the tobacco cultivation process, mainly due to the following limiting factors: 1. The transplanting cover of the three-dimensional covering technology is used in conjunction with conventional plastic mulch, and it also needs to be wrapped with plastic mulch, which does not solve the problem of "white pollution". Practical problems

2. Although the plastic mulch that needs to be wrapped in the transplanting cover can be operated in staggered farming hours, the processing process is cumbersome, time-consuming and labor-intensive. Even if the factory-made finished product is used, it will increase the input cost of the tobacco farmers

3. In case of continuous high temperature weather after transplanting tobacco seedlings, the transplanting cover needs to be ruptured, and the effects of heat preservation, moisture conservation and insect prevention will be significantly reduced, and it cannot adapt to climate changes before the tobacco cluster period
