干旱风沙区旱地地膜覆盖栽培西瓜试验

EXPERIMENT ON PLANTING WATERMELON BY COVERING PLASTIC FILM IN DRY FARMLAND OF ARID, SANDY AND WINDY AREA

旱地西瓜覆膜有明显的增温、保墒、抑草及提高产量、增进品质的效果。覆膜种植比对照可提前成熟上市 2 8d ,田间保苗率提高 30 % ,单株结瓜个数增加 0 3个 ,在产量和单价分别高出 2 4 885kg/hm2 和 0 0 6元 /kg的情况下 ,净收入增加 4 4 2 0 5元 /hm2 。旱地地膜覆盖栽培西瓜种植技术值得在干旱风沙区推广。

The watermelon planted in dry farmland by covering film has a good effect to increase temperature, keep or preserve temperature and moisture in topsoil, kill grass, obtain high yield and quality, maturity is about 28 days ahead of schedule and become available in the market, the rate of young seedling keep in field increase about 30%, number of watermelon per plant increase 0.3 fruits, this means 1659 kg/667 m 2 yield, 0.06 yuan/kg (RMB) increased. net income is about 294.7 yuan (RMB) per 667m 2. It is worthy of generalizing in dry field at arid, sandy and windy area.
