摘要
研究了不同育苗基质和播种密度对棉花出苗率和苗质的影响。结果表明:苗床采用蛭石与河沙复合基质,棉花出苗率较高且苗质较壮;最佳播种密度为8 cm×2 cm,苗床成苗数可达569.0个/m2,根冠比最高达0.210。
The medium composition for seedling culture of cotton were studied. Results showed that medium made of vermiculite and fiver sand was the best for cotton seedling cultivation. The best density was 8 cm × 2 cm, and seedling density was 569. 0 个/m^2, root-top ratio was 0. 210.
