1农艺要求(1)栽插时机。最好选择阴天土壤不干不湿时进行移栽,晴天温高时宜于午后移栽;不宜在大雨后移栽,避免形成柴根,应待雨过天晴,土壤水分适宜时再移栽;不宜移栽后灌水,移栽后灌水或在大雨后移栽,虽然成活率较高,但薯苗往往长时间长势不好,原因在于土壤呈水饱和状态,且土温偏低,这时土壤也变得比较密实,土壤中的氧气含量减少,妨碍根系发展,生长缓慢;久旱缺雨时,
1 agronomic requirements (1) planted timing. The best choice cloudy when the soil is not wet when transplanting, sunny high temperature should be transplanted in the afternoon; should not be transplanted after heavy rains, to avoid the formation of Chai Gen, should be sunny, when the soil moisture suitable transplanted ; Should not be transplanted after irrigation, transplanting irrigation or transplanting after heavy rains, although higher survival rate, but the potato seedlings tend to grow for a long time is not good, because the soil is saturated with water, and soil temperature is low, then The soil also becomes more dense, the oxygen content in the soil reduces, impedes the root system development, the growth is slow; When the drought and the rain,
