Method for cultivating peppers in open field in spring

Abstract

The invention discloses a method for cultivating peppers in an open field in spring. The method comprises the first step of selecting breeds, wherein the breed which is early-maturing and early-and-medium-maturing or the breed which is medium-maturing, medium-late-maturing, large in number of fruits, big in fruits, disease-resistant and heat-resistant can be selected according to various requirements; the second step of sowing and cultivating seedlings, wherein the appropriate seedling time in Henan province ranges from the first ten-day period of January to the first ten-day period of February, and the seedling using quantity is about 75 grams every 667 square meters; the third step of preparing soil and fertilizing, wherein generally, 5000-7500 kilograms of high-quality thoroughly decomposed organic fertilizer, 50 kilograms of calcium superphosphate, 30 kilograms of urea are applied every 667 square meters, and 30 kilograms of potassium sulphate serve as base fertilizer; the fourth step of field planting, wherein the field planting should be carried out in fine days after the local latest frost period is finished, the plantation density is 2-line peppers each low bank, the line spacing is 50 centimeters, the hill spacing ranges from 33 centimeters to 45 centimeters, and two pepper seedlings are planted in each hole. According to the method for cultivating the peppers in the open field in spring, the pepper species which is high-temperature resistant, antiviral, strong in growth vigor, big in fruits, thick in fruit flesh and cold resistant is provided, the fruits are centralized, the yield can be increased, the grade of the peppers can be improved, diseases can be prevented, the peppers can appear on the market continuously, the phenomena of flower dropping, fruit dropping and leaf dropping of the peppers can be avoided, and local economic benefits are greatly improved.

Description

technical field [0001] The invention relates to a method for cultivating peppers, in particular to a method for cultivating peppers in the open field in spring. Background technique [0002] Capsicum, also known as hot pepper, sea pepper or pepper eggplant, is native to Central and South America. It has erect stems and alternate single leaves. It is an annual plant in artificial cultivation. It can be divided into cherry peppers, cone peppers, clustered peppers, long There are five types of peppers and bell peppers. When the main stem grows 8-10 leaves, the first flower will be born, and the requirements for temperature and humidity are wider than those of tomatoes and eggplants. [0003] (1) Features [0004] 1. The main root of pepper is underdeveloped and the amount of roots is small. Most of the root groups are distributed in the topsoil layer of 10-15 cm. The root system is neither drought-tolerant nor waterlogging-resistant. Root regeneration ability is weaker than t...

AI Technical Summary

Problems solved by technology

[0006] 3. High temperature and drought induce the occurrence and spread of viral diseases, and high temperature and rainy conditions often lead to the prevalence of viral diseases

[0007] 4. Pepper flower drop, fruit drop and leaf fall (commonly known as "three fall") are also prone to occur. This is an important problem in pepper production and has a great impact on yield

[0011] 3. Water content: The water requirement is not too high, but the root group is underdeveloped, and the soil is not kept moist frequently, so it is difficult to obtain high yields
