A kind of capsicum overwintering seedling raising method

Abstract

The invention relates to the technical field of crop cultivation, in particular to a method for overwintering seedlings of peppers. The present invention comprises the following steps: (1) site selection and shed building; (2) seedbed excavation; (3) seedbed arrangement; (4) irrigation; (5) sowing; (6) covering with rice husk ash; (7) spraying water; (8) film covering and arching; (9) water management; (10) temperature management; (11) nutrient management; (12) pest control; (13) seedling collection. The overwintering seedling raising method of the present invention makes full use of the thermal stability and heat preservation of the soil layer and the high groundwater level moisturizing, no watering is required in the seedling raising process, and the appropriate humidity of the seedbed is maintained while reducing labor, reducing chilling damage and damage caused by excessive humidity. Diseases, at the same time, a variety of methods are used to prevent and control pests and diseases. In the process of pepper seedling cultivation, the rate of cold-damaged seedlings is only about 0.6%, and the incidence of diseases and insect pests is 0, which saves 38.3% of labor. The quality of the cultivated pepper seedlings is high. economic income.

Description

technical field

[0001] The invention relates to the technical field of crop cultivation, in particular to a method for overwintering seedlings of peppers. Background technique

[0002] Capsicum, an angiosperm of the genus Capsicum in the family Solanaceae, is an important vegetable crop and seasoning. The pepper cultivation area in the world is 3.7 million ha 2 , my country's cultivated area is 1.33 million hm 2 , accounting for 35% of the world's total pepper cultivation area.

[0003] Peppers are generally sown in spring, and the fruits are harvested in summer and autumn for food. With the application and promotion of protected cultivation techniques, the sowing time of peppers in professional vegetable bases is often more flexible. Farming methods such as early spring cultivation and autumn delayed cultivation are popular among farmers. In the plains of the middle and lower reaches of the Yangtze River, a considerable number of farmers advance the sowing period of pep...
