水稻育秧棚内稻壳覆盖马铃薯栽培技术研究

Study on Cultivation Technologies of Potato Covered with Rice Husk in Seedling Raising Shed of Rice

为明确水稻育秧棚内稻壳代替稻草覆盖马铃薯栽培技术的可行性,试验设置4个处理(稻壳覆盖厚度为15、10 cm,稻草覆盖厚度为15、10 cm),测定和比较覆盖的马铃薯出苗率、绿薯率、商品薯率、产量等指标。结果表明:稻壳覆盖厚度为15 cm时,马铃薯出苗率为93.2%,绿薯率最低,商品薯率(88.26%)与产量(667 m^(2)产量1840.60 kg)均最高。建议在我国东北地区推广应用。

In order to clarify the feasibility of the cultivation technology of potato covered with rice husk instead of rice straw in the seedling raising shed of rice,four treatments were set up in the experiment,containing rice husk covering thickness of 15 cm,rice husk covering thickness of 10 cm,rice straw covering thickness of 15 cm and rice straw covering thickness of 10 cm.The seedling emergence rate,green potato rate,commercial potato rate,yield and other indicators of potato covered were measured and compared.The results showed that when the thickness of rice husk was 15 cm,the potato emergence rate was 93.2%,the green potato rate was the lowest,and the commercial potato rate(88.26%)and yield(1840.60 kg per 667 m^(2))were the highest.It was suggested that it be popularized and applied in northeast China.
