- 摘要:
- 黎小豆具有生长期短、抗逆能力强等特点,能够弥补自然灾害所导致的粮食安全问题,同时也是维持我国粮食供求平衡的重要组成部分。为明确黎小豆生产关键技术,研究了不同播期、肥密和播深对黎小豆产量形成的影响。结果表明:6月5日播种的黎小豆,其结荚节数、有效荚数、株粒数、株粒重以及产量均优于5月16日和26日,为黎小豆在黑龙江第一积温带最适播期。以N、P、K纯量分别为27.75、70.95、58.65 kg·hm-2,密度为33.0万株·hm-2,组合的结荚节数、有效荚数、株粒数,株粒重、产量表现最优。随着播种深度的增加,黎小豆的出苗率和幼苗生长量呈降低趋势,而上胚轴长度则呈增加趋势。播种后6 ~10 d,2、4 cm处理的子叶干重最高,8、10 cm处理的茎干重始终高于其它处理。
- Abstract:
- Li adzuki bean has many characteristics,such as growth period is short,art ability, and it make up for the natural disasters caused by food safety issues,and maintain an important part of China’s grain supply and demand balance.For clearing Li adzuki bean production key technology,the different sowing date,fertilizer and sowing depth influence on Li adzuki bean yield formation were studied.The results showed that on June 5,sowing section of podding number,effective pod number,plant grain number,grain weight and yield were superior to the sowing,that for Li adzuki bean in the first optimum sowing date in Heilongjiang.N27.75 kg·hm-2、P2O570.95 kg·hm-2、K2O58.65 kg·hm-2was better than others on the number of podding section,effective pod number and grain number,plant grain weight.With high potassium processing yield the highest,Li adzuki bean for pleased potassium dense planting crops.With the increasing of depth,Li adzuki bean seedling emergence and seedling growth showed a decreased trend,while epicotyl length increased.After sowing for 6~10 d,2 and 4 cm treatment had the highest leaf dry weight,8 and 10 cm of stem dry weight were higher than others.
