Problems solved by technology

[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.

Embodiment 1

[0022] (1) Select the newly planted sugarcane field on the hillside, ditch horizontally along the contour line around the mountain, and close both ends, which is beneficial to the water and fertilizer conservation of the hillside sugarcane field. Use two plows and two harrows to prepare the land and plow to 35cm deep to achieve deep, loose and fine grain. , flat, ditch width of 90cm, ditch depth of 25cm, then apply slow and controlled release fertilizer, the amount per mu is 200kg, and use soil to cover fertilizer, then spread pesticides, and then adopt single ditch single row method of sowing;

[0023] (2) adopt width to be 150cm, the sugarcane weeding mulch film that thickness is 0.008mm carries out full film coverage to sugarcane field, coverage rate is 100%; Press the soil once at 5m, and the film should be close to the planting ditch, so as to maximize the temperature increase, water retention and weeding functions of the weeding film, and then take soil to compact and com...

Embodiment 2

[0026] (1) Select the newly planted sugarcane land, prepare the land with two plows and two harrows, plow to 40cm deep, loose, fine, and flat, when ditching, the furrow width is 120cm, and the furrow depth is 30cm, and then slow-release fertilizer is applied, per mu The dosage is 200kg, and the soil is covered with fertilizer, and then the insecticide is applied, and then the seeds are sown in a single ditch and two rows;

[0027] (2) adopt width to be 150cm, the sugarcane weeding mulch film that thickness is 0.008mm carries out full film coverage to sugarcane field, coverage rate is 100%; Press the soil once at 5m, and the film should be close to the planting ditch, so as to maximize the temperature increase, water retention and weeding functions of the weeding film, and then take soil to compact and compact the film on the planting ditch with crushed soil;

[0028] (3) Field management and harvesting of sugarcane.

[0029] The newly-planted sugar cane in this embodiment ado...

Embodiment 3

[0031] (1) Select the sugarcane field with perennial roots, and loosen the ridges of the planting furrows of the sugarcane fields with the perennial roots. The ridges and loose ridges should be separated from the cane heads by 5 cm, and the covering soil of the previous cane heads should be loosened, and then organic-inorganic compound fertilizers should be applied. The amount per mu is 150kg, and the soil is covered with fertilizer, and then the pesticide is applied;

[0032] (2) adopt width to be 150cm, the sugarcane weeding mulch film that thickness is 0.008mm carries out full film coverage to sugarcane field, coverage rate is 100%; Carry out a soil compaction at 5m, and the film should be close to the planting ditch, so as to maximize the temperature increase, water retention and weeding functions of the weeding film, and then take soil to compact and compact the film on the planting ditch with crushed soil;

[0033] (3) Field management and harvesting of sugarcane.

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.
