磐安是浙江中部的山区县,水田多处在山垄狭谷,常受侧渗冷水影响,地温低、日照少、产量低,全县有冷浸型低产田1400公顷。为了加快中低产田的改良,1995～1996年,我县示范推广水稻垄畦栽培技术,结果表明,该技术既能增产增效,又简单易行,是一项行之有效的改良措施。现将该技术介绍如下;1.水稻垄畦栽培优点(1)增产明显垄畦栽培改传统的淹水栽培为湿润栽培,使之提高畦面温度,改善土壤水、肥、气、热状况,利于根系生长,并增加了边行效应,从而促进早蘖、多穗、大穗,提高了结实率和千粒重。经对比田验 Pan’an is a mountainous county in the middle of Zhejiang. Paddy fields are often found in the ridge-shaped ridge of ridges and valleys, often affected by the seepage of cold water. The ground temperature is low, sunshine is low, and the yield is low. The county has 1,400 hectares of cold-soaked low-yielding fields. In order to speed up the improvement of middle and low yield fields, from 1995 to 1996, our county demonstrated and popularized rice ridge cultivation techniques. The results show that this technique is both effective and simple, and is an effective improvement measure. The technology is introduced as follows: 1, the advantages of rice ridge cultivation (1) increased yield significantly ridge cultivation change traditional flooding cultivation for wet cultivation, so as to improve the surface temperature, improve soil water, fertilizer, gas and heat conditions, and help Root growth, and increased side effects, thereby promoting the early tillering, more spike, big spike, increased seed setting rate and 1000-grain weight.
