Embodiment 1

[0027] A cultivation method for degrading plastic film covering sugarcane, comprising the steps of:

[0028] Step (1), preparation before planting: including mulch preparation, seedling preparation and site preparation and ditching steps;

[0029] (1.1) Mulching film preparation: select a degradable mulching film with a degradation time of 120 days, and the degradable mulching film is required to have a width of 1.5m, a thickness ≥ 0.008mm, and a light transmittance ≥ 80%;

[0030] (1.2) Seedling preparation: choose sugarcane variety ROC22, with 2-3 buds per section of stem;

[0031] (1.3) Site preparation and ditching: In paddy fields, sugarcane planting plots require deep plowing and fine harrowing, and paddy fields excavate cross-shaped drainage ditches and planting ditches; dry land sugarcane planting plots require ditching along contour lines, and then close both ends to form planting ditch; The depth of the cross-shaped drainage ditch is 50cm, and the width is 48cm; the...

Abstract

The invention relates to a cultivation method of biodegradation mulching film covering sugarcane, and belongs to the technical field of crop ecological environmental protection cultivation. The method comprises the steps that when the sugarcane is planted in winter or spring, the sugarcane is covered with the biodegradation mulching film, wherein the width is 1-6 m, the thickness is greater than 0.008 mm, the transmittance is greater than 80%, and the biodegradation time is 120 days, 60 days and 45 days; before the film covering, a planting ditch is irrigated with water of 5-8 tons per acre, to ensure the smooth emergence of sugarcane; after irrigation, full film covering is adopted; after the film covering, the film is biodegraded after a specific time period without recycling the mulching film; the labor cost of recycling the mulching film is saved 120 yuan per acre. According to a plurality of experiments on the sugarcane variety, the method has the advantages that the yield of the cultivated sugarcane is not affected by using the method; the net income of sugarcane planting farmers can be increased; and the soil ecological environment is effectively protected.

Description

technical field [0001] The invention belongs to the technical field of ecological and environment-friendly cultivation of crops, and in particular relates to a cultivation method for covering sugarcane with degradable plastic film. Background technique [0002] sugar cane( Saccharum hybrids spp . ) is a typical high photosynthetic efficiency C 4 Crops are the main sugar crops in the world. To achieve high yield of sugarcane, the whole growth period needs a lot of water. The drought in sugarcane planting in my country is particularly prominent. The sugarcane planting area on dry slopes accounts for more than 85% of the total area, and 90% of the sugarcane areas in the sugarcane area have no irrigation conditions. How to make full use of limited water resources and improve photosynthetic efficiency, yield and sugar content of sugarcane has become a focus of attention and research by experts at home and abroad. [0003] Plastic film mulching sugarcane cultivation has been ...
