A method of shading and controlling flowers of young pepper

Abstract

The invention relates to the technical field of agricultural cultivation, in particular to a shading and flower control method for young peppers. The method includes the step of conducting shading treatment on the young peppers. The shading treatment specifically includes the procedures that the shading degree of tree bodies during a recovery period is controlled within 60-75%, and the shading degree during a main flowering period is controlled to be equal to or smaller than 30%; the shading degree during a fruit expansion period is controlled to be equal to or smaller than 30%; the shading degree during a fruit slurry filling period is controlled within 60-75%; the shading degree during a fruit mature period is controlled within 60-75%. The shading and flower control method for the youngpeppers can reduce the flower amount of the young peppers during a non-production period; on the premise of not decreasing the growth amount of the peppers, the labor cost is reduced, the nutrient utilization efficiency of the peppers is improved, and scientific bases are provided for optimizing the flowering period regulation and the combined cultivation management mode during production of the peppers.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a method for shading and controlling flowers of young peppers. Background technique [0002] Pepper is a typical tropical spice, medicine and food crop. Its application fields in the food and medicine fields are constantly expanding, and the demand is also increasing. It is an important tropical economic crop in my country. Pepper light compensation point 100lx, light saturation range 2.5×10 4 ~5×10 4 lx is a shade-loving plant, and the light intensity in the main planting area of ​​Hainan Province from March to December is higher than 5×10 4 lx, so the pepper should be properly shaded. The growth and development process of pepper is divided into two stages: the juvenile stage (the period after the pepper cuttings are transplanted and planted and before the high-yield tree form is formed, about 2.5 to 3 years) and the production stage. The pepper flower buds a...

Problems solved by technology

[0006] More importantly, the traditional cultivation method of pepper currently adopted, because pepper is not shaded, pepper blooms normally in the non-production period and non-main flowering period, and picking flowers will increase labor costs, and not picking flowers will cause unnecessary loss of nutrients. At the same time, accelerate the aging speed of pepper and shorten its economic life
