Technology for organically cultivating and harvesting net house vegetables green sword bean, sweet corn and broccoli successively in one year

Abstract

The invention relates to technology for organically cultivating and harvesting net house vegetable green sword bean, sweet corn and broccoli successively in one year. The technical scheme of the invention comprises the following steps: (1) land parcel selection; (2) construction technology for an organic vegetable net house; (3) selection of breeds and arrangement of crops for rotation; (4) fertilization technology; (5) control technology for pests and weeds; and (6) harvesting technology. The technology has the following advantages that: the research on the technology for organically cultivating and harvesting the green sword bean, the sweet corn and the broccoli successively in one year is carried out, dependable crops and high quality can be achieved, and the production standard for the organic vegetables is met; a microclimate principle of the pests is changed and disturbed on the ecological environment, so the occurrence and damage of the plant diseases and insect pests are reduced; excessive absorption for a certain element in the soil is reduced, so imbalance of soil nutrient is avoided; and the soil is also fully utilized so as to create higher yield.

Description

1. Technical field: [0001] The invention relates to an agricultural planting technology, in particular to an organic cultivation technology of green beans-sweet corn-broccoli in net sheds for three harvests and three harvests a year. 2. Background technology: [0002] Organic vegetables refer to organic vegetables that come from organic agricultural production systems, where the quality of the ecological environment meets the specified standards, and do not use any harmful chemically synthesized pesticides, fertilizers and other chemical substances in the production process, and are produced and processed in accordance with international organic agricultural production requirements and corresponding standards. Vegetable products intended for human consumption and certified by an independent organic certification body. [0003] my country established the China Green Food Development Center in 1992 and joined the International Organic Agriculture Movement Federation in 1993. O...

Problems solved by technology

In terms of research, in the past, there were more qualitative research and less quantitative research; there were more research on single technology and less research on comprehensive supporting technology, lacking systematic and quantitative research. At present, there are still few enterprises engaged in organic vegetable production and processing, and large leading There are fewer enterprises, and there are few varieties of organic vegetables that can be processed. It is necessary to conduct further in-depth research on them
