吐鲁番光热气候资源丰富,但年内分布极不均匀,早春气温低而不稳,常造成春麦播期推迟,出苗缓慢,苗情较差。在小麦抽穗、开花、灌浆、乳熟的关键时期,又常遇干热风危害,易导致小麦花粉败育,授粉不良,穗粒数少,灌浆期短,光合产物转化不充分,千粒重轻,从而综合影响产量的提高。因此,如何保证小麦适时早熟,力争苗全苗壮,促进麦苗早发,使小麦生育期提前,减轻后期干热风危害,提高穗粒数,增加干粒重,是提高我市小麦单产的关键。地膜覆盖栽培技术作为一项农业增产

Turpan solar hot climate is rich in resources, but very uneven distribution during the year, early spring low temperature and instability, often resulting in delayed sowing of spring wheat, emergence is slow, poor seedling. In wheat heading, flowering, filling, milky key period, but also often dry hot wind damage, easy to lead to wheat pollen abortion, poor pollination, fewer grains per spike, short filling period, inadequate conversion of photosynthetic products, 1000 light weight, thus Combined impact of increased production. Therefore, it is the key to improve the yield of wheat in our city that how to ensure that wheat is timely and precocious, strive for seedling fullness, promote the early emergence of wheat seedling, advance the growth period of wheat, reduce the harm of late dry and hot wind, increase the number of grains and increase the dry weight of wheat.
