Problems solved by technology

The method of solving watermelon continuous cropping obstacles by grafting has been widely used, but there is an affinity between rootstock and scion and affects melon quality; selection of disease-resistant varieties is the most economical and effective measure to solve continuous cropping obstacles, but the selection of disease-resistant varieties requires It takes a long time, and the resistance of the selected disease-resistant varieties generally decreases after 3-4 years of continuous planting

Embodiment Construction

[0018] A planting method for relieving continuous cropping obstacles of watermelon, comprising the following steps:

[0019] (1) Planting of watermelon seedlings:

[0020] Plant 420 watermelons per mu, and dig a trench with a depth of 20 cm at a distance of 60 cm from the watermelon plants, and apply 1200 kg of organic fertilizer per mu;

[0021] (2) Planting of peanuts:

[0022] 7 days after planting watermelon, open a 5cm deep small ditch around each watermelon, plant 2 peanuts around a watermelon, the peanut seedlings are 12cm away from the root of the watermelon, and the seeding rate of peanuts is 68kg / hm 2 ;

[0023] (3) When the peanut seedling grows to more than 20cm, cut off the ground part, and repeat the operation 3 times to control the growth of the peanut seedling.

[0024] Among them, the cut peanut branches and leaves, vermicompost and vermiculite are mixed and composted according to the mass ratio of 4:9:1, and are used as fertilizer for secondary use to fert...

Abstract

The invention discloses a planting method for relieving watermelon successive cropping obstacles. Through a planting method of intercropping peanuts and watermelons, secreta of peanut roots has the effect of facilitating growth of watermelon seedlings, and the components, playing the facilitation role, in the secreta of the peanut roots are water-soluble organic substances and include an allelopathic substance triacontanol which plays a role of facilitating growth of the watermelons; after being thoroughly decomposed and fermented, branches and leaves of peanut saplings can be used as fertilizer, on one hand, resource recycling is achieved, and the cost is reduced; on the other hand, substances obtained by thoroughly decomposing the branches and leaves of the peanut saplings have relatively high allelopathic promotion effects on the growth of the watermelons, the watermelons are effectively prevented from autotoxicity, the watermelon successive cropping obstacles are relieved, and therefore ecological and economic benefits are improved.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a planting method for alleviating obstacles to continuous cropping of watermelons. Background technique [0002] Continuous cropping of watermelon is forbidden, and autotoxicity is an important factor for continuous cropping obstacles in watermelon. The known autotoxic substances in watermelon are benzoic acid and cinnamic acid. At present, with the shortening of the crop rotation cycle, the incidence of Fusarium wilt tends to increase year by year, and the yield decreases year by year. Watermelons generally require at least 6 years of crop rotation. However, due to the limitations of my country's arable land area and the current land use system, watermelon production cannot implement a strict crop rotation system. The crop rotation period is getting shorter and shorter, and repeated cropping is inevitable. At present, to overcome the obstacles of watermelon c...
