Cultivation method for waterlogging reduction and sugar increase of western sweet melons

Abstract

The invention discloses a cultivation method for waterlogging reduction and sugar increase of western sweet melons, that is, through the establishment of deep ditch high border short shed ventilationand active drainage and waterlogging reduction, combined with fan ventilation and moisture blowing+moisture absorption medium, and with the help of biochemical regulators to inhibit the growth, bad climate formation of wet damage on the early spring shed western sweet melons is reduced to control and reduce the accumulation of excess water in the melons and fruit to ensure that the western sweet melons in the multi-wet and waterlogged cultivation environment to achieve high quality and high yield. The process specifically includes: selecting waterlogging resistant varieties; establishing a deep ditch and high ridge and internal and external drainage system; building a short shed ventilating in two ends, making a high ridge on the melon row, covering the ridge with a membrane and installing a drip irrigation pipe belt under the membrane; closing the shed for drainage and waterlogging reduction on long and continuous rainy days; performing ventilation and dampness on sunny days; when the humidity is high after sitting of the melons, spraying bamboo charcoal and other materials in roots of the western sweet melons to absorb moisture; when the humidity difference inside and outside the shed is large, installing an exhaust fan in the shed to blow out the wet air (till the relative humidity in the shed falls below 70%).

Description

technical field [0001] The invention relates to a protected cultivation technique in agricultural protected gardening, in particular to a cultivation method for watermelon with increased precipitation. Background technique [0002] The technology of using greenhouses to produce melons has been widely used in a certain range, and its double-greenhouse multi-layer covering technology has solved the problem of low temperature stagnation in late winter and early spring in coastal areas. However, the Meiyu season along the coast of Jiangsu and Zhejiang is the critical period for the formation of melon production and fruit setting in early spring. Due to the high humidity in the field and air at this time, the melon plants absorb more water and fertilizer, and the multi-layer covering of greenhouses cannot block the impact of humidity on the growth of melons. Influence, under high humidity conditions, melons tend to form vigorous and long-distance running tendrils, frequent pests ...
