Efficient method for producing high-quality watermelons and muskmelons in gravel-mulched field

Abstract

The invention relates to an efficient method for producing high-quality watermelons and muskmelons in gravel-mulched field. The method comprises following steps: planing out a sandy layer on an old gravel-mulched field; digging planting holes in the soil layer; well mixing substrate and biological bacterial fertilizer; then sowing and transplanting melon seedlings. Experiments show that the method of the present invention can significantly improve the watermelon melon growth environment level of the old sandy land with reduced or lost production capacity, reduce the incidence of diseases. Field control effect on wilt of watermelon in gravel-mulched fields reaches 43.4-88.4%; fruit quality is increased; the sugar content in the center of fruits reaches 12%; output per unit area is raised; it can restore the production capacity of the old sandy lands which are more than 10 years old. The yield per mu is over 1600 kg, with the highest yield of 2492.6kg and increased by 13.7-82.1%.

Description

technical field [0001] The invention relates to a method for high-quality and high-efficiency production of watermelons and melons in sand-pressed land, and belongs to the technical field of sand-pressed cultivation of watermelons and melons. Background technique [0002] A field covered with a layer of 7-20cm gravel or pebbles with coarse sand on the surface of the wasteland is called a pressed sand field, and watermelon, muskmelon and seed melon are mainly planted on the pressed sand field. This special production mode was created and invented in the long-term production practice of adapting to drought, little rain and saline-alkaline barren land. It is an economical and effective dry farming agricultural production mode. Since Zhongwei City was established in 2004, it has developed rapidly. The main production area centered around the Xiangshan area has a total of about 1 million mu of sand-pressing land, and it has become the leading industry for local people to get rid ...

AI Technical Summary

Problems solved by technology

However, with many years of heavy cropping of pressed sand melons, aging sandy land, and improper water and fertilizer management, the problem of sand-pressed watermelon diseases began to appear in 2010. Diseases such as watermelon wilt, watermelon anthracnose, watermelon virus disease, and watermelon bacterial leaf spot There are different degrees of occurrence and harm in all regions, especially the soil-borne disease watermelon wilt, which is common in the entire pressing sand melon planting area, especially in the sand pressing land for more than 7 years, the mortality rate of watermelon is relatively high, the highest is more than 18%.
