摘要
在冬种马铃薯上进行稻草覆盖腐熟还田试验,结果表明:每667 m2覆盖稻草350 kg,在同等施肥等条件下,马铃薯增产180.1 kg,增产率8.43%;成品薯率提高4.59个百分点,大薯率提高7.9个百分点;每667 m2净收入增加345.79元。
Experiment of rice straw mulching and returning its decomposed residues to soil on winter potato was carried out. The results showed that, under equivalent fertilization conditions, BS0 kg/667 m2 （525 kg/hm2 ） straw mulching could increase tuber yield by 180.1 kg,/667 m2 （2701.5 kg/hm2 ） with 8.43% increasing rate, the percentage of commercial tubers by 4.59 percentage point, the percentage of big tubers by 7.9 percentage point, and net income by 345.79 yuart/per 667 m2 （ 5186.85 yuan/hm2 ）.
