地膜玉米栽培技术是地面上覆盖一层塑料薄膜,充分利用太阳的辐射热,从而提高低温和减少土壤表层的热能散失,增加积温,能起到保墒和防早的作用,改善土壤理化性状,利于土壤微生物的活动,加速养份分解,提高土壤供肥和保肥能力,充分发挥肥效,促进玉值株健壮生长,抑制杂草生长,达到全苗壮苗早熟高产的一项新的栽培技术。1产量结构指标亩理论株数为5500-6000株,亩实收穗数5000-5500穗,穗
Plastic film corn cultivation technology is covered with a layer of plastic film on the ground, make full use of the sun’s radiant heat, thereby enhancing the low temperature and reduce soil surface heat loss, increase accumulation of temperature, can play a role in preserving soil moisture and early protection, improve soil physical and chemical properties, and benefit Soil microbial activity, accelerate the decomposition of nutrients, improve soil fertility and fertilizer capacity, give full play to fertilizer effect, promote the robust growth of jade plant value, inhibit the growth of weeds, seedlings and seedlings to achieve a new high-yielding cultivation techniques. 1 Yield Structure Indicators The theoretical number of acres of acres of 5500-6000 plants, acres of real ears spike 5000-5500 spike, spike
