Embodiment Construction

[0019] The present invention will be further described below in conjunction with embodiment.

[0020] This embodiment includes the following steps:

[0021] 1) In mid-July, after the previous crop of watermelon is cultivated, remove the plastic film, rake the ridge surface, and open a ditch along the ridge surface. The width of the ditch is 40 cm, and the ditch is 40 cm deep.

[0022] 2) Along the two sides of the ditching direction of the ridge surface, level the surface soil with a nail rake and sow the leguminous crop sweet potato, with a seeding rate of 8kg / 667m 2 , After sowing, use nail rakes to level the topsoil in rows, and irrigate in the ditch to moisten the ridge surface. The root system of sweet potato is developed, which can loosen the soil, change the permeability of the soil, and then achieve the effect of changing the physical and chemical properties of the soil. Utilize the growth inhibition and allelopathic effect of the sweet potato itself to inhibit t...

Abstract

The invention discloses a protected area watermelon continuous cropping no-tillage cultivation method. The method comprises the following steps: preparing soil and ditching in the middle ten days of July; seeding leguminous crop-Vicia spp; watering, and maintaining the humidity of soil; pressing all unbroken roots of the Vicia spp into ditches; covering ridge faces with surface soil; in the first ten days of February, plugging transplant in a hotbed and planting when each watermelon seedling has one leaf and one core; in the last ten days of March, uncovering a small row cover, entering greenhouse normal management, and stopping watermelon cultivation in the first ten days of July; The method simplifies watermelon continuous cropping cultivation procedures. Moreover, through the method that unbroken roots of the Vicia spp directly cover soil and a mulching film is used as green manure, the method improves soil fertility, balances the soil biology environment, and changes the soil physicochemical property, so that disease resistance of field watermelons is further improved, the sugar degree of watermelons is improved by 1-2%, the output is improved by more than 200-600% than that of traditional continuous cropping, and a new path is developed for watermelon continuous cropping.

Description

technical field [0001] The invention relates to a method for continuous cropping and no-tillage cultivation of plants in protected land, in particular to a method for continuous cropping and no-tillage cultivation of watermelons in protected land, and belongs to the technical field of plant cultivation. Background technique [0002] With the continuous increase of watermelon production in summer, the continuous cropping area of ​​watermelon is also increasing year by year. Due to the continuous cropping of watermelon, the natural balance of soil microorganisms and inorganic components will be destroyed, and soil pathogens will develop, leading to the spread of soil diseases, manifested as large areas of fusarium wilt Fusarium wilt usually causes 15-30% loss of watermelon yield, 50-85% of serious fields, or even no harvest, which seriously affects the yield and benefit of watermelon. Continuous cropping obstacles have become restrictions on watermelon yield , especially the ...
