Method for preventing and controlling excessive seedlings in chili floating seedling raising

Abstract

The invention belongs to the technical field of floating seedling raising, and discloses a method for preventing and controlling excessive seedlings in chili floating seedling raising. The method comprises the following steps: properly controlling a seedling raising process according to local transplanting time; adopting seedling-raising floating trays with proper specifications, wherein the number of holes of the seedling-raising floating trays with the same area is not too large, and the seedling-raising floating trays with 100-160 holes are adopted; performing ventilating, brightening, cooling and humidity control in a seedling raising shed; adjusting the water level of a nursery pond according to nursery seasons and air temperature, and adjusting concentration of a nursery pond nutrient solution according to different periods after seedling emergence; and adopting 15% paclobutrazol powder, 85.3% daminozide crystal pure and 50% chlormequat-chloride aqueous solution for seed soakingtreatment and foliage spraying prevention and control. According to the method, the plant height can be reduced, the stem diameter can be increased, the quality of chili seedlings can be improved, labor is saved, and industrialized and intensive seedling culture is facilitated. Meanwhile, a scientific basis is provided for improvement of a chili floating seedling raising technology, and the chiliindustry is better served.

Description

technical field [0001] The invention belongs to the technical field of floating seedling cultivation, and in particular relates to a method for preventing and controlling excessive seedlings in floating seedling cultivation of peppers. Background technique [0002] At present: Floating seedling raising technology is a relatively advanced seedling raising technology, which is widely used in the southwestern region of China. It was first applied in tobacco seedling raising, and then popularized and applied in solanaceous vegetable seedling raising, especially in pepper seedling raising. [0003] Floating seedling raising is a seedling raising method that uses white polystyrene floating trays and soilless floating seedling raising substrates, seeds are sown in the substrate in the floating tray holes, and float on the nutrient liquid surface of the nursery pool. In the floating seedling cultivation of pepper, it is easy to appear the phenomenon of excessive growth of seedlings,...
