摘要
马铃薯在稻田免耕稻草覆盖栽培冬种试验表明 ,免耕稻草覆盖 1 0cm比常耕栽培亩增产马铃薯 50 1 3 % ,免耕稻草覆盖 8cm增产 34 44% ,免耕稻草覆盖 6cm增产 2 4 93 % ,增产达极显著值。该方法免除了栽培翻耕和中耕除草环节 ,亩减少投工 8工天 ,省工省时。该方法能使马铃薯的生长发育具有前缓中快后稳健的特点 ,出苗整齐 ,成薯率高 ,现蕾开花期植株生长速度快 ,分枝多 ,叶面积大 ,块茎形成早数量多 ,块茎膨大速度快 ,每株块茎数量是常耕栽培的 1 6～ 2 2倍 ,单株块茎增重 32 8～ 1 2 5 6克。能有效达到稻草还田和增加薯苗还田的效果 ,有利于增加土壤有机质 ,提高土壤肥力 ,减少生态环境污染。
A trial on the cultivation of potato planted in non-tilling paddy field in winter showed that the output of the potato from non-tilling paddy with 10cm thick layer of rice stalk covering over it increased by 50 13%, increased by 34 44% as 10cm thick layer of rice stalk and increased by 24 93% as 6cm thick layer of rice stalk Thus, the incremental output yields notable result, comparing to that of the potato from the conventional tilling paddy field The cultivation method can reduce time on soil tilling and weeds removing, and decrease the input of 8 workday labors per mu, thus saving time and labor intensity It also promotes the growth of potato, results in the effect of retuning rice stalk and potato seedlings to paddy field, thus increases the organic substance and fertility of soil, decrease the pollution level of eco-environment
