不同种植方式对棉田土壤温度、棉花耗水和生长的影响
Effects of different planting patterns on soil temperature water use and growth of cotton
摘要
Abstract
This study was undertaken to examine the effects of flat planting, furrow sowing and film-mulching-bed planting on soil temperature, water use and growth of cotton. Results showed that film-mulching-bed planting increased soil temperature by increasing the daily maximum temperature in the early growth stages of cotton. After flowering, the effects were not obvious. At the same time film-bed and furrow sowing could conserve soil water and reduce soil evaporation . The amount of field water use under film-bed planting was significantly lower than that under furrow and flat sowing by 62.4% and 25.3% in the growth season of 2010, while by 26.1% and 10.3% in 2011. As a result, cotton net photosynthetic rate, biomass and final yield under film-mulching-bed planting were higher than that under furrow and flat planting. Compared with flat sowing, water use efficiency under film-bed and furrow planting was obviously improved by 62.4% and 25.3% for the season of 2010, while by 26.1 % and 10.3% in 2011. Though furrow planting was better in soil moisture conservation than flat planting, no significant difference was found on the cotton yield of the two practices.关键词
