移栽棉花,每亩施用菜饼80斤,尿素35斤,究竟怎样施用才能最有利于棉花壮苗早发,稳长多桃,早熟不早衰,保证棉花增产丰收?这里,我介绍一下我场移栽棉花不同施肥时间、方法、用量对产量的影响。过去几年,我们在棉花移栽时每亩将80斤菜饼一次施完,做为棉花一生所需底肥。这时雨水一般较少,水分不足,土温较低,施下的菜饼不易腐烂和分解,加上又不习惯早施追肥,移栽后的棉苗不能及时从土壤中吸取应有的养料,棉花“蹲苗”半月后,茎红叶黄株矮小,至此每亩才追施尿素12—15斤,恰恰违背了棉花各个生长发育阶段所需肥料的客观要求,致使棉苗迟发。到了梅雨天,土壤温度不断升高,雨量也随之增 Cotton transplanting, per mu acre applied 80 pounds of urea, 35 pounds of urea, how to apply the most conducive to cotton seedlings early onset, long and steady peach, precocious puberty, to ensure that cotton yield bumper? Here, I introduce my field Effects of different fertilizing time, methods and dosage of transplanting cotton on yield. In the past few years, we transplanted cotton in the transplanting of 80 pounds per mu when the pie once applied, as the base fertilizer needed for a lifetime of cotton. At this time the rain is generally less, lack of water, soil temperature is low, under the rotten vegetables and perishable decomposition, coupled with not accustomed to top dressing, transplanted cotton seedlings can not be timely from the soil to absorb due nourishment Cotton “squat seedlings” after a half months, stems and leaves yellow stubble, so far only topdressing 12-15 kg of urea per acre, just to break the cotton growth and development stage required fertilizer objective requirements, resulting in delayed cotton seedlings. By the rainy day, the temperature of the soil keeps rising, and the rainfall also increases
