(一)早稻“坐棵”原因 ①红花草施用量多(超过1500公斤/亩),耕翻后又随即播秧,红花草没有腐烂,或正处在微生物分解状态.微生物活动旺盛,一需耗氧、二需从土壤中争夺养分(尤其是氮素),影响水稻根系的呼吸,使其中毒等。②红花草在分解时,土壤发泡,浮泥很
(1) Reasons why early rice “sits in the middle of the tree” (1) When the amount of safflower grass used is more than 1,500 kg / mu, sowing seedlings are transplanted immediately after cultivation and the safflower grass does not decay, or is in the state of microbial decomposition. Oxygen consumption, the two need to compete for nutrients from the soil (especially nitrogen), affecting rice root respiration, poisoning and so on. ② safflower grass decomposition, the soil foam, mud is very muddy
