Autumn delayed overwintering on-field fresh-keeping cultivation method for greenhouse peppers

Abstract

The invention discloses an autumn delayed overwintering on-field fresh-keeping cultivation method for greenhouse peppers, which comprises the following steps: selecting fine seeds; planting; managing the cultivation; performing pest control; harvesting and the like. According to the autumn delayed overwintering on-field fresh-keeping cultivation method for the greenhouse peppers, a high-efficient anti-season special greenhouse peppers cultivation technique is used for delaying the supply period of the normally open field autumn batched peppers from the original second half of October to the days after December till the next April for selling in the market in succession; the technology implementation is simple; the operability is strong; the application is wide; the requirement for the peppers of the long winter and early spring slack season market is met; according to the technique, the special red pepper products are marketed in the slack season in a staggered peak form and have the advantages of on-field fresh keeping and marketing on the basis of selecting the time and period, so that the economic benefit is very obvious and stable; the plant diseases and insect pests are few during the production process; the quality of the acquired peppers is high.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a fresh-keeping cultivation method for hot peppers in a greenhouse after autumn delay and overwintering in the field. Background technique [0002] Pepper is an important vegetable and condiment. It has high nutritional value and contains a variety of vitamins and trace elements, such as vitamin C, B, carotene, calcium, iron, phosphorus, etc. Studies have shown that every kilogram of pepper contains vitamin C It is 1050 mg, which is 21 times that of eggplant, 5 times that of tomato, 4 times that of Chinese cabbage, and 3 times that of white radish. Capsicum has the functions of warming the middle, expelling cold, appetizing and eliminating food. Greenhouse hot peppers are overwintered after autumn and kept fresh in the field. It means that through facility protection measures, specific cultivation techniques and unique overwintering fresh-keeping management techniques in the field, ...

AI Technical Summary

Problems solved by technology

The early temperature is high and the light is too strong, which is not conducive to the growth of pepper seedlings and seedlings, especially the frequent rainfall from the seedling stage to the adult plant stage, and slight negligence in cultivation and management can easily induce the occurrence of viral diseases, resulting in a large reduction in production, or even a failure to harvest.

Secondly, the suitable temperature time for flowering and fruit expansion is short, and the fruit preservation period often encounters low temperature and low light seasons, which can easily lead to flower and fruit drop and disease epidemics

Therefore, if the management of any link in the cultivation process is not in place, it can lead to cultivation failure or low yield and poor profit.
