摘要
终霜冻和春季低温冷害是造成新疆棉区大面积严重缺苗、毁种重播的主要原因之一。全疆大部棉区棉花在播种期间均发生过霜冻害 ,其中多发区分布在北疆沿天山一带棉区及和田、且末棉区。且棉花早播与终霜冻害和低温冷害成正比。
The latest frost and microthermal damage in spring are of the main reasons of serious lacking of seedling and resowing the same field in every cotton region in Xinjiang. The cottons had been frosted in the large part of cotton region in Xinjiang during seeding time. The ferquently occurring of frost injury-cotton region are distributed along Tianshan in north region and Hetian's、Qiemo's cotton region in Xinjiang. The early seedings are in direct proportion to the latest forst injury and microthermal damage in springs. Analysis the probability of cotton seedling for infectde with the frost and microthermal damage during different seeding time may determine the optimum cotton's seeding time in every region in Xinjiang.
