Straw utilization method for improving yield of overwintering planted zucchini

Abstract

The invention discloses a novel straw utilization method for improving the yield of overwintering planted zucchini. The method specifically comprises the steps that zucchini planting rows are ditched and crop straw is buried in advance after greenhouse selection, variety selection and straw preparation and before field planting of the zucchini in October, mulching film laying and straw covering are conducted at the operation rows after field planting of the zucchini, and finally management after zucchini pulling is conducted. The novel straw utilization method has the advantages that the problems that the ground temperature is low, humidity is high, the concentration of carbon dioxide is low and soil hardening and salinization happen during overwintering plantation of the zucchini are effectively solved, the using amount of pesticide and fertilizer is reduced, the occurrence rate of diseases, insect pests and weeds is lowered, the yield is increased by 34.5%, and the zucchini appears on the market 10-12 days ahead of time; meanwhile, compared with a traditional straw bioreactor landfill technology, strain purchase and frequent holing are not needed in the method, the defect that the application cost is too high is overcome on the premise that the straw decay speed is not affected, and the yield-increasing effect is obvious.

Description

Technical field [0001] The invention relates to a new method for comprehensive utilization of straw on vegetables, in particular to a straw utilization method for improving the output of overwintering zucchini in a warm-winter greenhouse. Background technique [0002] In recent years, with the vigorous promotion of modern agriculture in my country, the area of ​​facility vegetables has expanded year by year, and has become a "three high" industry with high input, high output, and high efficiency. Planted indoors year after year, soil-borne diseases such as Fusarium wilt are serious, and a large amount of chemical fertilizers are used, resulting in soil compaction and salinization. 2. Due to the relatively closed environment of the shed, in order to maintain a suitable temperature for vegetables during planting in winter, the air is released later in the morning, and the time for airing is less throughout the day, and the concentration of carbon dioxide is low, which is no...

[0002] In recent years, with the vigorous promotion of modern agriculture in my country, the area of ​​protected vegetables has expanded year by year, and has become a "three high" industry with high input, high output, and high efficiency. Planted indoors year after year, soil-borne diseases such as Fusarium wilt are serious, and a large amount of chemical fertilizers are used, resulting in soil compaction and salinization

3. When planting in winter, the ground temperature in the greenhouse is low, and the root growth is poor, which is not conducive to the healthy growth of the plant
