Paddy-upland rotation method for managing protected watermelon continuous cropping obstacle

Abstract

The invention discloses a paddy-upland rotation general mode for managing protected watermelon continuous cropping obstacle. The paddy-upland rotation method includes the steps of implementing a continuous flooding processing for four months after protected greenhouse watermelon harvest in spring; flexibly planting aquatic vegetables such as ipomoea aquatic, watercress, water bamboo, arrowhead, water chestnut, lotus root and water caltrop according to local agricultural planting habits and local market demands; ending the growing of aquatic vegetables after winter coming; and draining off water, plowing the land and freezing the upturned soil so as to continuously plant watermelons in spring of the following year. With no impact on watermelon yield, the paddy-upland rotation method is capable of effectively preventing the fusarium wilt of the cropping water melon in the following year and dangers of soil salinization.

Description

technical field [0001] The invention relates to a facility cultivation mode, in particular to a paddy and dry rotation cultivation method for effectively preventing facility watermelon continuous cropping obstacles. Background technique [0002] Watermelon is an important horticultural crop in the world and one of the top ten fruits in the world. It occupies a very prominent position especially in summer fruits. Its cultivated area and total output are both in the forefront of fruits in the world. my country is the largest watermelon producer in the world, accounting for more than 45% of the world's area and total output. Since the 1990s, due to the adjustment of the agricultural industry structure and comparative economic benefits, the cultivation of watermelons in greenhouses and other protected areas across the country has increased significantly. With the industrialization and scale of watermelon production, the multiple cropping index of protected cultivation has incre...

AI Technical Summary

Problems solved by technology

The current relatively mature model is to plant a batch of watermelons and then plant rice continuously for 3 years, which can effectively prevent the occurrence of diseases such as Fusarium wilt, but requires watermelon producers to frequently disassemble and assemble facilities, resulting in waste of facility resources and increased labor costs.
