Cultivation technique for promoting early-sowing of sugarcane and continuously retaining water and temperature

Abstract

The invention relates to the technical field of plant cultivation, in particular to a cultivation technique for promoting early-sowing of sugarcane and continuously retaining water and temperature. The invention adopts the main technical measure of applying water retaining agent and plastic film mulching in the production process, the application effects of one earliness and two retention can be obviously realized through the water retaining agent and the plastic film mulching in the cultivation and production of sugarcane, the one earliness refers to early sowing, namely the sugarcane can be sowed anytime and cannot be affected by drought, and the bud rate of the sugarcane can reach more than 95 percent; the two retention refers to water retention and temperature retention, namely the soil temperature can be increased by 2-4 DEG C, the germination period of the sugarcane can be shortened to 42-46 days, the weight ratio of soil water content is maintained about 25 percent and is maintained for 40 days, and the sugarcane bud can smoothly sprout. The cultivation technique solves the problem that the sugarcane cannot sufficiently elongate due to drought in autumn and creates favorable conditions for realizing the high and stable yield of sugarcane production.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a cultivation technology capable of promoting early planting of sugarcane and continuous water retention and heat preservation. Background technique [0002] "Depending on the sky for food" has always been a true portrayal of traditional sugarcane production. In the face of changing climate and natural disasters, sugarcane farmers seem helpless and helpless. In order to obtain high-quality and high-yield commercial sugar, sugar enterprises also need raw material cane with sufficient growth period, because sugarcane with insufficient growth period not only has low yield, but also has low sugar content. The start-up period of sugar production is from November to April of the following year, so if there is a sufficient growth period for spring sugar cane planting, the best time to plant sugar cane in spring is early spring, but in early spring there is less rain, the soil ...

Problems solved by technology

The implementation of this technology makes there be a reasonable space between the holes, improves the ventilation and light transmission conditions in the field, and can increase the photosynthesis of sugarcane. However, the technology is complicated and requires much more cane buds than conventional planting.
