水稻旱育浅植技术,是一套严格而又规范的水稻栽培技术,要求在秧田期不建立水层,只保持秧地土壤湿润,秧地接近旱田条件下进行育秧,实行秧苗带土浅栽,合理密植。其优点有:土壤氧气充足,有利于萌芽种子进行旺盛的有氧呼吸,促进种子贮藏物质的转化,提高秧苗素质,旱秧移栽后无明显返青期,发根力强,分蘖发生快;旱秧细胞组织致密,植株挺韧,耐低温和干旱,抗逆性强;早育秧能提早播种,安全育秧,又能提早成熟,有利于抗低温增产。
Rice dry cultivation shallow planting technology is a set of strict and standardized rice cultivation techniques, requires no water layer in the seedling stage, only to keep the seedling soil moist, seedling planting conditions close to the dry field, the implementation of seedlings with shallow soil planted Reasonable and close planting. The advantages are: sufficient oxygen in soil, favorable for sprouting seed to carry out strong aerobic respiration, promoting the transformation of seed storage material, improving the quality of seedling, no obvious turning green after transplanting, strong rooting and tillering; drought Stem cells dense, very tough plant, low temperature and drought resistance, strong resistance; early seedling can sow early, safe seedling, but also early maturity, is conducive to low temperature increase yield.
