Cotton-garlic double-cropping simplified cultivation method

Abstract

The invention discloses a cotton-garlic double-cropping simplified cultivation method. The method has the advantages that a traditional method which interplants spring cotton in a garlic field about one month before garlic harvesting or transplants spring cotton after garlic harvesting is changed into a method which directly sows short-season cotton after garlic harvesting, mechanical cotton sowing is achieved, and the mu manpower of cotton sowing is less than 1; the direct short-season cotton sowing does not need pruning cultivation, mu manpower is only about 2, manpower is saved, and high efficiency is achieved; only 20kg / mu of nitrogen-potassium compound fertilizer is applied once from the bud flourishing period to the initial flowering period, cost is saved, and chemical fertilizer pollution is reduced; manual harvesting is performed once when cotton boll opening reaches 30-50%, then a corn harvester is used to harvest the cotton bolls which do not open, and the garlic is harvestedmechanically; by the double-cropping simplified cultivation method, simplified and mechanical cotton sowing, management and harvesting can be achieved.

Description

technical field [0001] The invention relates to a light and simplified cultivation method for two crops of cotton and garlic a year, which belongs to the field of crop cultivation. Background technique [0002] The interplanting of garlic and cotton is a typical high-efficiency planting model, and the two crops complement each other and bring out the best in each other. The interplanting period of garlic and cotton is short, and the garlic has been harvested before budding of cotton, and the two crops can effectively use the resources of temperature and light. At the same time, the interplanting of garlic and cotton can realize "one film for two purposes, one fertilizer for two purposes, and one water for two purposes", saving costs and increasing efficiency, and increasing the ratio of output to input. The traditional cotton and garlic cultivation method is twice a year. Sow garlic from late September to early and mid-October, and transplant cotton between garlic rows in e...

Problems solved by technology

But this kind of cultivation method usually requires cotton seedlings to be transplanted in nutrient bowls. The garlic interplanted with cotton cannot be harvested mechanically, otherwise it will damage the cotton seedlings. It can only be harvested manually, which requires a lot of labor input and is labor-intensive and time-consuming.

In order to solve these problems, the improvement made by the predecessors is to change the traditional nutrient bowl (soil bowl) seedling cultivation and manual transplanting of cotton before garlic harvest to light and simple seedling cultivation (soil bowl seedling cultivation is changed to matrix seedling cultivation), and mechanical transplantation of garlic after harvest. Planting cotton can reduce the labor intensity of cotton seedling raising and transplanting to a certain extent, and garlic can also be harvested mechanically, but the operation process and cultivation links are not reduced, and there are still problems such as cumbersome cultivation management, large investment, and high cost.
