Planting method for crop rotation of peanuts and watermelons

Abstract

The invention relates to the technical field of agriculture, and discloses a planting method for crop rotation of peanuts and watermelons in order to solve the problem that the quality of watermelons is affected due to continuous cropping of the watermelons at present, and the planting method comprises the following steps: selecting a land parcel with uniform soil fertilizer and high and dry terrain, deeply rotating soil to be below 30cm, building a greenhouse, and digging deep ditches outside the greenhouse. The previous-crop peanuts improve the soil microenvironment, have a positive effect on reduction of fusarium wilt in watermelon continuous cropping land, and shorten the multiple cropping age limit of watermelons; the crop rotation of peanuts and watermelons fully improves the utilization rate of greenhouse facilities, promotes the income increase of farmers, and provides a new greenhouse efficient crop rotation mode for the farmers; the problem of poor taste of grafted seedlings is solved, the watermelon quality is improved, and the market price is obviously superior to that of grafted watermelons; nitrogen in the atmosphere is converted into organic nitrogen by leguminous crops through root nodules, the organic nitrogen is fixed in plant bodies, the application amount of nitrogen fertilizer for later-crop watermelons is reduced, and soil hardening and salinization are prevented.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a method for planting peanuts and watermelons in rotation. Background technique [0002] As one of the main fruits in my country, watermelon occupies the first place in the world in terms of cultivation area and total output. However, in the watermelon planting, long-term continuous cropping of watermelon will cause soil acidification, salinization, unbalanced cropping, proliferation of diseases and insect pests, and watermelon self-poisoning and other continuous cropping obstacles, which seriously affect the quality of watermelon and the sustainable development of the industry. Scholars at home and abroad have conducted a large number of experiments on the mechanism and solution of the problem of continuous cropping of watermelon. The main obstacles to preventing watermelon continuous cropping in production are screening of disease-resistant varieties, grafting, etc., or sim...

However, a single control measure has many limitations. What’s more, it will have a negative impact on the soil or crops. It takes a long time to screen resistant varieties. Grafting cultivation has a certain impact on fruit quality. Chemical control is likely to cause soil environmental damage. Pollution, etc.
