1995年,我县严塘镇邮亭村示范推广麦田压稻草27公顷,普遍获得了明显的增产效果。据对比调查,麦田压稻草的小麦667平方米产量为215.5公斤,比来压稻草的增产30.5公斤,增产16.5%。麦田压稻草的主要增产作用在于:一是保湿又防土壤板结,提高出苗率8%~12%;二是减少杂草56%~82%;三是提高土壤有机质含量,容重减轻,耕性变好;四是减少稻草中有效钾的流失。
In 1995, Yanting Village, Yantang County in our county demonstrated and promoted 27 hectares of wheat straw under pressure, and generally obtained obvious yield-increasing effect. According to a comparative survey, the output of straw wheat in a wheat field is 215.5 kg with 667 m 2 of wheat straw, an increase of 30.5 kg compared with that of rice straw, an increase of 16.5%. The main role of cropland straw in increasing yield is: First, moisture and prevent soil compaction, increased germination rate of 8% to 12%; the second is to reduce weed 56% to 82%; third is to improve soil organic matter content, bulk density, Good; Fourth, reduce the loss of available potassium in straw.
