依当地气温条件做好水稻计划栽培

寒地水稻的产量和品质受当地气温条件所左右。对佳木斯市近期二十年的气温实测资料做了统计分析,并计算出当地水稻主栽品种各生育阶段的活动积温,结合水稻生育界限温度等资料,绘制了水稻计划栽培图。以安全抽穗期为中心,确定了当地水稻栽培各主要生育阶段的界限时期、提出了适宜种植品种,以便充分利用当地热能资源,防御低温冷害,而实行计划栽培,为水稻生产安全成熟,提高品质和产量。

Practice Planned Rice Cultivation by Local Weather

The yield and quality of rice in cold area was determined by local air temperature.In this article,the planned cultivation of rice was pointed out through statistics analysis of air temperature in Jiamusi in the recent 20 years and calculating the active accumulated temperature of different rice growth stage among the local main crop varieties and boundary temperature of growth period.Considering the heading time of rice as the center,the key period in different growth stages of rice and suitable variety were confirmed,so it can make full use of local heat energy to precaution low temperature damage.Practicing planned rice cultivation could ensure the secure maturing and enhance the quality and yield of rice.
