近年来推广麦(油)后棉的营养钵苗,由于苗龄较长,棉苗的许多根系穿透钵体,扎到苗床土层,起钵时,很多较幼嫩根系断在苗床土层。这种苗移栽后“落难”严重,为此作钵下垫膜培育棉苗的试验。 (一) 本试验选择晚油菜茬移栽棉苗。苗床地前茬为蔬菜,未施基肥,4月上旬手工制钵。播种前钵下垫薄膜。4月15日播种,同时设不垫薄膜的作对照。苗床管理措施与常规育苗相同,只是在连续干 In recent years to promote the wheat (oil) cotton seedlings after the nutrition bowl, due to the longer seedling age, many cotton seedlings penetrate the bowl, tied to the soil layer, from the bowl, a lot of young roots broken in the soil bed . This seedlings transplanted “fall hard” serious, for this Bowl membrane cotton seedling cultivation test. (A) This experiment choose late rapeseed transplanting cotton seedlings. Pre-crop seedbed for vegetables, no base fertilizer, handmade bowls in early April. Before sowing bowls pad film. April 15 sowing, at the same time set no pad film as a control. Seedbed management practices and conventional nursery the same, but in a row dry
