杂交水稻种植面积占我区单季晚稻和连作晚稻面积的90%以上。杂交稻种子颖壳松散、芽谷、瘪谷多,加上种子贮藏不当和近几年来粮食价格下跌,农民种粮食积极性下降。秧田管理措施不倒位,造成发芽率和成秧率低,影响了杂交水稻的播种质量和种植面积。因此,应采取相应技术措施,提高杂交水稻种子的发芽率和成秧率,以确保我区杂交水稻的播种质量,达到增产增效。
Hybrid rice acreage accounted for more than 90% of the area of single-season late rice and continuous cropping rice in our district. Loose hybrid rice seed glume, bud Valley, deflated Valley more, coupled with improper storage of seeds and food prices in recent years, the enthusiasm of farmers grow food declined. Seedling management measures do not upside down, resulting in low germination rate and seedling yield, affecting the sowing quality and planting area of hybrid rice. Therefore, we should take appropriate technical measures to improve the germination rate and seedling yield of hybrid rice seeds in order to ensure the sowing quality of hybrid rice in our region, to increase yield and increase efficiency.
