Embodiment

[0021] (1) Nurturing:

[0022] Seedbed preparation: per hm 2 0.05-0.1hm for Daejeon 2 Seedbed land plan, mix well with compost and garden soil 1:1, add (per m 3 ) ammonium sulfate 0.8kg, calcium superphosphate 2.5kg, calcium magnesium phosphate fertilizer 4kg, fully stirred as seedbed soil;

[0023] Sowing and seedling raising: put the seeds in the sun for 2-3 days before sowing, pre-soak them with clean water for 3-6 hours, then soak them with 10% trisodium phosphate for 20-30 minutes, wash them and place them at 25-30°C After 4-6 days, when most of the seeds are white, they can be sown. The sowing should be from late December to early January. If the seedlings are too long, you can use paclobutrazol at a concentration of 5-25mg / L when the leaves are 3-4. Spray the plants, when the seedlings grow to 3 leaves, spray the plants with 0.2% urea and 0.3% potassium dihydrogen phosphate solution, once every 5 days, spray 3 times in a row, grow on the seedbed for 70-90 days, and g...

Abstract

The chemistry regulation and control cultivate means of the hot pepper's high output and good quality is one of the cultivate means of the vegetable crop. Basing on the insufficiency of recent hot pepper cultivate means, dispose hot pepper at its critical growing period by using plant growth regulator such as fruitone, drop-defending element and casing coupling amine, as well as cultivate synthetically by using cultivate measures such as scientific, rational manure and proper planting density, including nursery sock growing, planting, chemical controlled treatment, fertilizer water quality management, branching and wiping bud processes. It makes the output of the hot pepper increase quickly, with the average increase production of 18percent to 30percent, the quality improves evidently, besides, the content of vitamin C and deoxidizing sugar are improved apparently, it is also suitable for different kinds of hot pepper.

Description

technical field [0001] The invention relates to a cultivation method for vegetable crops, in particular to a high-yield and high-quality cultivation method for peppers. Background technique [0002] At present, there are many ways to cultivate peppers, such as plastic greenhouse cultivation method, plastic film covering method, single chemical control method and so on. However, these methods have certain problems, such as plastic greenhouse cultivation investment, high cost, high labor, many diseases, serious soil salinization, etc.; although a single plastic film mulching cultivation method can increase the yield of early vegetables, it is prone to lodging and premature aging. In terms of chemical regulation methods, although there are many types and quantities of plant growth regulators, and the scope of application is also relatively wide, but looking at the achievements at home and abroad, most of the research focuses on the selection and selection of a single plant grow...
