Water conservation method with sugarcane leaf and mulch film full cover

Abstract

The invention relates to a full-covering method for holding water for sugar cane leaf and ground film. A ground film with a width of 60cm and a thickness of 0.008 to 0.012cm is adopted to cover the planting rows of the sugar cane. 8 to10cm of the both sides of the ground film are respectively compacted by fine soil so as to ensure the transparent horizontal surface of the ground film to be more than 40cm. The sugar cane leaves after the sugar cane is harvested are adopted among the planting rows and are covered on the row middle after straightening. The sugar cane leaves are closely connected with the ground film with no empty land and simultaneously compact the sugar cane leaves. The invention solves the water holding problem for stubble sugar cane planting, realizes the full-covering between the sugar cane land via the ground film and the sugar cane leaves, and also realizes effective water holding on the sugar cane land; thereby greatly reducing the water vaporizing of the sugar cane land, maintaining the water of the soil and overcoming the water restraining factors in sugar cane planting.

Description

Technical field: [0001] The invention relates to the technical field of water conservation in sugarcane cultivation, in particular to a water conservation method for fully covering sugarcane leaves and plastic film. Background technique: [0002] Sugarcane is an important sugar crop in my country. The growth of sugarcane requires a lot of water, and the growth cycle is as long as 10-12 months. Because most of the sugarcane areas in my country are affected by the monsoon climate, there is little rain and drought in winter and spring, and the soil moisture content is low, which seriously affects the growth of sugarcane. Germination and emergence, the lowest result in insufficient effective stems of sugarcane, small growth, low and unstable yield. [0003] At present, the known sugarcane water retention technology mainly adopts plastic film covering, and the use of plastic film to cover sugarcane planting rows can achieve the water retention effect of sugarcane planting rows to ...

[0002] Sugarcane is an important sugar crop in my country. The growth of sugarcane requires a lot of water, and the growth cycle is as long as 10-12 months. Because most of the sugarcane areas in my country are affected by the monsoon climate, there is little rain and drought in winter and spring, and the soil moisture content is low, which seriously affects the growth of sugarcane. Germination and emergence, the lowest results in insufficient effective stems of sugarcane, small growth, low and unstable yield

[0003] At present, the known sugarcane water retention technology mainly adopts plastic film covering, and the use of plastic film to cover sugarcane planting rows can achieve the water retention effect of sugarcane planting rows to a certain extent. The soil is not covered, resulting in a large amount of water evaporation, poor water retention effect
