High-efficiency water and fertilizer management method for culturing of sugarcane

Abstract

The invention relates to a high-efficiency water and fertilizer management method for culturing of sugarcane. The high-efficiency water and fertilizer management method specifically comprises the following steps of ploughing sugarcane fields, raking the ploughed fields and leveling the raked fields by a conventional method, ditching the leveled fields into sugarcane planting ditches, and absorbing water by using a water retaining agent so as to obtain solid water; preparing a base fertilizer as needed, applying and spreading the base fertilizer to the sugarcane planting ditches, and then placing sugarcane seeds in the sugarcane planting ditches; and after the seeds are sowed, uniformly spreading the solid water to the sugarcane seeds, and then performing covering with crushed mud. Through the implementation of the high-efficiency water and fertilizer management method disclosed by the invention, the water retaining agent is used for preparing the solid water and has the functions of repeatedly absorbing water, retaining water and the like, when the water retaining agent is applied and placed on the periphery of the sugarcane seeds, miniature reservoirs are matched equivalently; when the sugarcane field is arid, moisture in the water retaining agent can be slowly released, so that moisture required for growth of the sugarcane is guaranteed, and when it rains, the water retaining agent can also absorb moisture, so that the water retaining agent can release moisture once again when the field is arid. The content of the moisture in the soil is kept about 25-40%, and is kept for about 40 days. At an early spring arid stage, the water retaining agent can guarantee sugarcane buds to smoothly sprout, and the problem that due to autumn drought, the sugarcane cannot sufficiently extend is also solved.

Description

technical field [0001] The invention belongs to the field of new plant cultivation technologies, and in particular relates to a highly efficient water and fertilizer management method during sugarcane cultivation. Background technique [0002] Sugarcane is usually grown on relatively dry slopes. Because of the drought, sugarcane farmers can only plant sugarcane in March-April after the spring rains, while sugar companies start to squeeze sugarcane in November every year. In this way, the growth of sugarcane is only 7 to 8 months, and the sugarcane with insufficient growth period not only has low yield, but also has low sugar content. In order to obtain high-quality and high-yield commercial sugar, sugar enterprises also need raw material cane with a sufficient growth period. Therefore, if sugarcane planted in spring has a sufficient growth period, sugar enterprises and sugarcane farmers can achieve double harvests. Therefore, sugarcane planting should be done early rather ...

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.
