Paddy-upland rotation and combined planting-breeding method of organic fruits and vegetables with Rana catesbeiana in multi-span greenhouse

Abstract

The invention discloses a paddy-upland rotation and combined planting-breeding method of organic fruits and vegetables with Rana catesbeiana in a multi-span greenhouse. The method of the invention comprises the steps of (1) designing a paddy-upland rotation and combined planting-breeding greenhouse, including a Rana catesbeiana breeding greenhouse and a planting greenhouse of organic fruits and vegetables; (2) determining the periods, to be specific, breeding Rana catesbeiana from tadpole breeding in spring March until winter sales is complete, and continuously planting two crops in the planting greenhouse of organic fruits and vegetables from February to December; (3) carrying out combined planting and breeding with paddy-upland rotation. The combined planting and breeding with paddy-upland rotation involves combination of planting and breeding and paddy-upland rotation; the precipitate of excrement from Rana catesbeiana in soil is an organic fertilizer for a next crop; organics discharged with water are fermented via a precipitating tank to serve as an organic fertilizer applied to irrigating water for fruit and vegetable cultivation; the ingenious combination of the Rana catesbeiana breeding technique and the planting technique of organic fruits and vegetables helps solve, at low cost, the problems of continuous cropping obstacle and salinization for vegetable production inprotective cultivation; sustainable development with greatly increased benefit is attained at the premise of ensuring production of organic vegetables.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting and breeding, and in particular relates to a method for combining organic fruits and vegetables in one-piece greenhouses with bullfrogs in paddy and dry rotation cropping and breeding. Background technique [0002] With the improvement of living standards, people pay more and more attention to the health of food, which greatly promotes the development of organic agriculture, especially organic vegetables are welcomed by more and more consumers. Planting tomato, cucumber, eggplant and other vine crops in conjoined greenhouses can make full use of the facility space and improve economic benefits. Therefore, planting organic fruits and vegetables in high-end facilities such as conjoined greenhouses (supporting sunshade nets, thermal insulation films and water curtain fans) is one of the best choices in modern facility agriculture. But the biggest problem of modern protected cultivation...

AI Technical Summary

Problems solved by technology

The problem is that the economic benefit of conjoined greenhouses caused by planting aquatic crops is low, labor costs are high, and soil fertility is reduced, so growers seldom adopt this measure

American bullfrogs are very popular in the market. Because during the breeding process, bullfrog excrement is discharged along with the water, polluting the local water environment, so many places have banned breeding, causing the market to be in short supply.
