Sugarcane continuous water and fertilizer retaining cultivation management method

Abstract

The invention discloses a sugarcane continuous water and fertilizer retaining cultivation management method. The method comprises the steps of preparing the corresponding fertilizer at each growing period of the sugarcane; diluting the fertilizer into a liquid fertilizer and absorbing the liquid fertilizer with a super absorbent resin to make it solid and applying the fertilizer around the sugarcane seeds; adding water and fertilizer in the late stage, namely diluting the fertilizer into a liquid fertilizer and then spraying it to the sugarcane, and the super absorbent resin set around the sugarcane root absorbs the nutrient solution and solidifies the liquid fertilizer first, and then releases the liquid fertilizer slowly to have the liquid fertilizer absorbed by the sugarcane. In the invention, the super absorbent resin can absorb and retain water repeatedly, and the water 200-300 times of self weight can be preserved. The liquid fertilizer applied around the sugarcane seeds is equal to applying multiple mini reservoirs; the liquid fertilizer or water in the super absorbent resin can be slowly released for sugarcane absorption in drought, and the super absorbent resin can absorb water when it rains for releasing when it is drought next time.

Description

technical field [0001] The invention belongs to the field of new plant cultivation technologies, and in particular relates to a cultivation management method for continuous water and fertilizer conservation of sugarcane. 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 ...

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.
