Cultivation method for solving continuous cropping obstacles in protected agriculture

Abstract

The invention discloses a cultivation method for solving continuous cropping obstacles in protected agriculture. The method includes the key steps of performing deep tillage, burying livestock manure and straws, irrigating, covering greenhouses, letting in fresh air, applying biological organic fertilizers and the like, in agricultural greenhouse idle reasons July to August each year. The cultivation method has the advantages that the comprehensive technique of integrating soil deep tillage, greenhouse high-temperature covering, straw returning, soil sterilization and soil secondary salinization reduction is achieved, soil EC values are decreased, fewer soil-borne diseases occur, more organic matters are provided for the soil, the damage of continuous cropping obstacles to crops is substantially solved accordingly, and safety production of the protected agriculture is achieved.

Description

technical field [0001] The invention relates to the cultivation technology of continuous cropping in farmland, in particular to a cultivation method for solving obstacles to continuous cropping in facility agriculture. Background technique [0002] Continuous cropping obstacle refers to the phenomenon that when the same crop or related crops are continuously cultivated in the same soil, even under normal cultivation and management conditions, the growth potential will become weak, and the yield and quality will decrease. The continuous cropping phenomenon is common all over the world, and it is widely distributed in Japan, China and India in Asia, and the most serious ones are cereals and vegetables. With the development of social economy and the improvement of people's living standards, as well as the relative reduction of arable area and the demand for a balanced supply of vegetables in the market, the cultivation area of ​​protected vegetables in my country has continued ...

Problems solved by technology

However, due to the emergence of business models such as industrialization, specialization, and large-scale production of facilities, distinctive professional production areas and farmers engaged in a specific vegetable production have emerged in various parts of our country, especially the main types of vegetables cultivated in facilities. Limited to a few fruits and vegetables with relatively high economic benefits, resulting in the phenomenon of continuous cropping in some areas is quite common, continuous cropping obstacles have seriously restricted the sustainable development of facility agricultural production

[0003] Existing techniques for prevention and control of continuous cropping obstacles: reasonable crop rotation, intercropping and fallow; soil sterilization and residue treatment; use of resistant varieties; biological control; scientific fertilization; Effects on crops
