Multi-cropping cultivation method for non-heading Chinese cabbages and abelmoschus esculentus

Abstract

The invention discloses a multi-cropping cultivation method for non-heading Chinese cabbage and okra, which comprises the following steps: hybrid seed production of non-heading Chinese cabbage: adopting a small-plant seed collecting method for hybrid seed production of non-heading Chinese cabbage, performing plug seedling culture on parent seeds of non-heading Chinese cabbage in a seedling culture facility from late December to early January, performing open-field film mulching and field planting in early and middle March, and harvesting when seed pods are yellow and ripe at the end of May; after non-heading Chinese cabbage seeds are harvested, 3-4 m < 3 > of thoroughly decomposed farmyard manure, 25 kg of ternary compound fertilizer and 15 kg of potassium sulfate are applied per mu, base fertilizer is turned into a plough layer with the thickness of 20-30 cm, raking and leveling are carried out, multiple cropping of okra is carried out from the end of May to the beginning of June in the current year, the okra is directly sown in an open field, and harvesting is carried out in July to October. According to the method, the hybrid seeds of the non-heading Chinese cabbages and the abelmoschus esculentus which are short in planting period are selected for multiple cropping, farmland resources can be reasonably utilized, the planting income is increased, and the method has remarkable planting and popularization significance.

Description

technical field [0001] The invention belongs to the technical field of multiple crop cultivation, and in particular relates to a multiple crop cultivation method of non-heading Chinese cabbage and okra. Background technique [0002] Non-heading cabbage is the most abundant vegetable in minerals and vitamins. It is rich in vitamin C, which can promote skin cell metabolism, prevent skin roughness and pigmentation, and vitamin C also forms a "hyaluronic acid inhibitor" in the body. ", this substance has an anti-cancer effect, which can make cancer cells lose their vitality; it also contains a lot of crude fiber, regular consumption can reduce atherosclerosis and maintain blood vessel elasticity. There are many varieties of non-heading Chinese cabbage, and most of them are the first generation of hybrids. With the increase of the sown area, the amount of seeds used has also increased year by year, and the production area of ​​the first-generation hybrid seeds has also expanded....

Problems solved by technology

[0004] With people's urgent needs for health care and nutrition, the planting area of ​​okra is increasing year by year, but due to the increase in land prices and labor costs, the sowing date of okra is later than other crops, and pure cultivation will waste land and light and heat resources to a certain extent , the benefit is relatively low, which limits the expansion of the okra planting scale and the development of the industry
