A kind of hydroponic method of capsicum

Abstract

The invention discloses a chili hydroponic method which includes the following steps that 1, chili seeds are cleaned, sterilized and wrapped with wet gauze till white buds are exposed; 2, roots are downwards placed into small holes formed in a sponge block, and then the sponge block is placed into a seedling nutrient solution for seedling culture; 3, the sponge block after seedling culture is transferred into a circular hydroponic nutrient solution for culture. According to the chili hydroponic method, growth throughout the whole year can be achieved under the red light ranging from 650 nm to 670 nm, the blue light ranging from 440 nm to 460 nm and the compound light, meanwhile three-dimensional culture can be conducted, the yield in unit area is high, no plant disease and insect pest exist, and growth of plants can be adjusted under an artificial light source.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable cultivation, in particular to a hydroponic method for peppers. Background technique [0002] Capsicum (Capsicum annuum L.) belongs to the genus Capsicum of Solanaceae, which is an annual or limited perennial herbaceous plant. Yugan pepper is a high-quality local variety resource of pepper, and it is one of the important famous and special vegetable brands in Yugan County, Jiangxi Province. Yugan Because of its thin skin and tender meat, especially its fresh taste, spicy taste, moderate fragrance, and no stomach injury, pepper was once used as a "tribute to the court" and regarded as a treasure on the plate. It is welcomed by the masses and has extremely high economic value. Due to the limitation of natural conditions, it is difficult to supply the annual supply of both dried hot peppers and ordinary hot peppers on the market. For this reason, the market price of hot peppers soars sharp...

Problems solved by technology

However, in recent years, due to the continuous cropping of the land all year round, the serious aggravation of soil diseases and insect pests, and the increase of heavy metal pollution in the soil at the same time, the yield and quality of peppers have declined, especially for the remaining dried peppers.

[0003] In the prior art, the cultivation of plants mainly includes indoor cultivation technology, which has the advantages of not being restricted by seasons, plant growth period is long, and annual balanced production can be realized. At the same time, indoor cultivation has fewer pests and diseases, no pesticides, no Heavy metal residues; at the same time, the growth and quality of crops can be controlled by controlling the light source and nutrient solution; indoor cultivation technology can also be divided into three-dimensional cultivation technology, soilless cultivation technology, etc. The three-dimensional cultivation technology has the advantages of high yield per unit area. At the same time, this technology can adopt automatic control technology, and it also has the advantages of low labor intensity and can reduce labor. The soilless cultivation technology is a cultivation method that realizes annual continuous production of crops in the facility. Occupying arable land and saving land resources; and soilless cultivation is also divided into matrix cultivation and hydroponics, of which hydroponics can provide more stable and sufficient nutrients for the root system, and the technology is clean and hygienic in implementation, free from pests and diseases, and has a high degree of automation High, while the current capsicum mainly uses the matrix cultivation technology in the soilless cultivation technology, and the hydroponic method technology has not yet been reported.
