土壤水势下限对寒地水稻品质的影响
Effects of Lower Limit of Soil Water Potential on Grain Quality of Rice in Cold Region
摘要
Abstract
With Kenjiandao 5 and Kendao 12 as materials, the effects of intermittent water-controlling treatments at -8 to -10 kPa of soil water potential on rice grain quality in cold region from reviving to maturity were studied in a pot experiment in a chamber rainproof by examining soil water potential with a negative pressure soil moisture meter. The results of showed that head rice rate, amylose content, setback value of grains at different positions decreased, whereas protein content, prola-min content, glutelin content, globulin content, peak viscosity value and breakdown value of grains at different positions increased. Therefore, the rice taste value decreased.关键词
