A sugarcane full-film mulching cultivation technique with both herbicidal and insect-proof effects

Abstract

The invention belongs to the technical field of plant cultivation, and discloses a sugarcane full film covering type cultivation technology with weeding and pest controlling effects. The sugarcane full film covering type cultivation technology comprises the following steps of (1) for new sugarcane planting land, preparing land, furrowing, applying fertilizer, spreading a pesticide and sowing, or for ratoon sugarcane land, breaking ridge, loosening soil , applying the fertilizer, and spreading the pesticide; (2) covering the sugarcane land by a sugarcane weeding ground film, with the coverage rate of 100%, i.e., covering the ground film along the direction vertical to a planting furrow by a ground film covering method, compacting soil on the covering film at intervals of 3-5m, tightly attaching the film to the planting furrow, fetching soil, and using crushed soil to press and compact the ground film on the planting furrow; (3) managing the field, and harvesting sugarcane by chopping. The sugarcane full film covering type cultivation technology has the advantages that the sugarcane weeding ground film vertical covering method is adopted, the film covering efficiency is high, the film covering is stable, and the weeding and pest controlling effects are good.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a sugarcane full-film mulching cultivation technology with the functions of weed control and insect control. Background technique [0002] As an important sugar crop, sugarcane has a large demand for water throughout the growth period. However, due to its low economic added value, sugarcane planting areas are mainly distributed in dry slopes with little rainfall and poor soil fertility. Poor conditions and lack of scientific management methods lead to severe weeds and insects in the field, which greatly affects the yield and sugar content of sugarcane. The traditional plastic film mulching cultivation technology can play a good role in protecting the moisture of sugarcane fields, but because only the cane furrows are covered with plastic film, there will still be a large amount of water loss between sugarcane rows, which will easily cause water loss in the l...

[0002] As an important sugar crop, sugarcane has a large demand for water throughout the growth period. However, due to its low economic added value, sugarcane planting areas are mainly distributed in dry slopes with little rainfall and poor soil fertility. Poor conditions and lack of scientific management methods lead to severe weeds and insects in the field, which greatly affects the yield and sugar content of sugarcane

The traditional plastic film mulching cultivation technique can play a good role in protecting the moisture of sugarcane fields, but because only the cane furrows are covered with plastic film, there will still be a large amount of water loss between the sugarcane rows, which will easily cause water loss in the later stage of sugarcane growth

The existing sugarcane full-film mulching cultivation technology (CN101480131A) requires water to be sprayed with herbicides before mulching, but the sugarcane field is generally far away from the water source, and it is difficult to get water, and it is easy to destroy the herbicides during field operations such as film mulching after spraying herbicides. layer, which affects the weed control effect in the later stage. At the same time, the efficiency of this method is low, which greatly affects the enthusiasm of farmers for planting sugarcane; When laying, it is necessary to consider the width of the planting ditch and the distance of the cane row according to the width of the film, which also reduces the artificial efficiency and use efficiency of the film to a certain extent.
