In-situ two-crop cultivation method for watermelons in land with sand injection

Abstract

The invention discloses an in-situ two-crop cultivation method for watermelons in land with sand injection. Firstly, a first crop of watermelons is planted in the land with sand injection, when the first crop of watermelons enters the later stage of watermelon expansion, a sand layer is dug at the outermost sides of watermelon pits in the direction of a drip irrigation belt, and grafted watermelonseedlings with 3-4 flower leaves are planted for planting of a second crop of watermelons; irrigation is conducted on the watermelon pits, and then a layer of fine sand with the thickness of 3-4 cm covers the watermelon pits; after the first crop of watermelons is ripe and harvested, the first crop of watermelon seedlings are dug up from the roots, the second crop of watermelon seedlings are notdamaged, the watermelon pits are arranged, and the drip irrigation belt and a mulching films laid during planting of the first crop of watermelons are reserved; and water and fertilizer are supplied in time through a drip irrigation water and fertilizer integrated system. According to the method, the in-situ two-crop planting method is adopted, the cost is saved, the yield is increased, the salesperiod is prolonged, the income is increased, the survival rate of second crop of watermelon seedlings is increased through the shading and protecting effects of the first crop of watermelon seedlings, the cost of manual hole digging, mulching films and drip irrigation belts is reduced in the second-crop planting process, the cost is reduced, meanwhile, residual film pollution is reduced, and theenvironment is protected.

Description

technical field [0001] The invention belongs to the technical field of melon and fruit cultivation, and in particular relates to a method for in-situ two-crop cultivation of watermelon in a sand-pressed field. Background technique [0002] Pressed sand land can solve the problem that it is not suitable for planting in arid areas with little rain or saline-alkali land. It can effectively maintain soil moisture and increase soil moisture. It is mainly used to grow watermelons, muskmelons, and seed melons. The quality of the planted melons is excellent. The main process of traditionally planting watermelons in sand-pressed land is: firstly dig out the sand layer covering the ground to form melon nests with a radius of 20cm, then plant germinated seeds or grafted seedlings in the soil, and then cover them with film. The planting process is cumbersome, and it is difficult to cultivate, fertilize, and rotate crops in sand-pressed land. The cost of planting one crop per year is hig...

AI Technical Summary

Problems solved by technology

The planting process is cumbersome, and it is difficult to cultivate, fertilize, and rotate crops in sand-pressed land. The cost of planting one crop per year is high, and the yield is low. At the same time, the traditional sand-pressed watermelons are mainly on the market from late June to late July. The market time of other main watermelon producing areas overlaps, resulting in low and unstable watermelon prices, low planting efficiency, and commercial planting cannot be realized
