棉花薄膜育苗移栽是夺取棉花早熟、优质、高产的一项栽培措施。然而,这项措施的成败和增产幅度的大小,很大程度上取决于育苗阶段棉苗的素质。由于育苗移栽棉花比直播花要提前播一个月,风险较多、直接影响早苗、全苗、壮苗、早发。我们通过多年的实践体会到,在育苗全过程中,必须紧紧抓住四点:即选好种,提高种子质量,粒选后用0.2%的25%多菌灵浸种;备好土,提高床土质量,床土经过冬耕冻垡、春耕晒垡,腐熟细碎过筛的猪羊灰杂肥与熟土按3∶7比例,每亩苗床再加过磷酸钙100斤
Cotton film nursery transplanting is to seize the precocious cotton, high-quality, high-yielding cultivation measures. However, the success or failure of this measure and the size of its increase will depend to a large extent on the quality of cotton seedlings at the nursery stage. As the seedling transplanting cotton flowers than direct broadcast to be broadcast one month in advance, the risk of more direct impact on seedlings, seedlings, strong seedlings, early onset. Through years of practice, we have realized that in the whole process of nursery, we must firmly grasp the four points: that is, choose a good species, improve the quality of seeds, seed dressing with 0.2% 25% carbendazim; prepared soil, improve Bed soil quality, bed soil after winter tritulent 垡, plowing spring sunburn, rotten fine broken sift pigs and pigs mixed fertilizer and cooked soil according to the ratio of 3: 7, per acre seedbed plus superphosphate 100 kg
