近年来我们通过试验示范,成功地摸索出了一种简便易行、省工省力、成本低、效益高的稻田免耕种植马铃薯新技术。目前这种新技术正在浙西南山区迅速扩大推广。实践表明,马铃薯采用免耕种植全程覆盖稻草技术具有播种早、出苗齐、结薯早、效益好等优点。现将其主要栽培技术介绍如下。1.选用良种,适时播种稻田免耕全程覆盖稻草种植马铃薯有春播马铃薯和秋播马铃薯两种。春播以选用东农303、春薯5号和克新2号等品种为好。如选用脱毒种薯则增产效果更显著,可比普通种薯增产50%以上。秋播则宜选用金冠、蒙古5号和郑薯85-2等品种。若种薯休眠期
In recent years, through experiments and demonstrations, we successfully explored a new technology for no-tillage cultivation of rice in paddy fields that is easy to operate, labor-saving, labor-saving, low-cost and high-efficiency. At present, this new technology is being rapidly expanded and popularized in mountainous area of southwest Zhejiang. Practice shows that the whole tillage of potatoes with no-till planted straw has the advantages of early sowing, early emergence, early tuberization and good benefits. Now its main cultivation techniques are as follows. 1. Selection of elite, timely sowing paddy field no-till covering the entire straw planting There are two kinds of spring-sowed potato and autumn sowing potato. Spring sowing to choose Dongnong 303, Spring Potato No. 5 and Kexin 2 varieties as well. Such as the use of virus-free seed is more significant yield increase, than ordinary seed production increase of 50%. Autumn seeding should use the Golden Delicious, Mongolian No. 5 and Zheng Shu 85-2 and other varieties. If the kind of potato dormant period
