棉花尼龙育苗移栽是夺取棉花早熟、优质、高产的栽培措施之一。这项措施的成败和增产幅度的大小,很大程度取决于育苗阶段棉苗的素质。而且由于育苗移栽棉花播种的时间比直播的要提前一个月,风险较大,搞得不好会直接影响早苗全苗和壮苗早发。我们通过多年的实践,体会到要育好苗,必须紧紧抓住“四个一”。即选好一粒种,提高种子质量。种籽先粒选,然后用千分之二25％的多菌灵浸种。备好一堆土,提高钵土质量。床土经过冬耕冻垡、春耕晒垡后,加腐熟细碎过筛的猪羊灰杂肥与熟土,比例为3:7。每亩苗床加过磷酸钙100斤,充分捣细拌和。3月中旬打钵时每亩再加粪水100担。制好一个钵,提高播种质量。要求营养钵外表光滑,外紧内松,揿上去有弹性,摸上去有指纹,掰开来有毛缝眼。育好一床苗,提高棉苗素质。育好棉苗,我们的体会是要抓住四个主要矛盾。即“争早苗,水分是主要矛盾;保全苗,
Cotton nylon seedling transplant is to seize cotton precocity, high-quality, high-yielding cultivation measures. The success or failure of this measure and the size of the increase will depend greatly on the quality of cotton seedlings at the nursery stage. And because of transplanting cotton seedling planting time than the live broadcast one month in advance, the risk is greater, not doing well will have a direct impact on early seedling seedlings and seedlings early onset. Through years of practice, we have learned that to cultivate seedlings, we must firmly grasp the “four ones.” That is, choose a seed, improve seed quality. Seeds are first pelleted and then soaked with 25% of carbendazim. Prepare a pile of soil, improve soil quality. Bed soil after winter tritulent 垡, plowing spring drying, add rotten finely crushed pigs goat gray mixed with cooked soil, the ratio of 3: 7. Acres per acre plus calcium phosphate 100 pounds, full pound fine mix. In mid-March, when bowl was added, 100 mu of manure was added per acre. Make a good bowl, improve the quality of planting. Requires nutrition Bowl smooth appearance, tight outside the loose, 揿 up elastic, feels fingerprinted, breaking apart to have seams. Breeding a seedling, improve the quality of cotton seedlings. Breeding cotton seedlings, our experience is to grasp the four major contradictions. That "fight early seedlings, moisture is the main contradiction; Paul seedlings,
