Study on the Suitable Sowing Amount of Rape under No-tillage and Ploughing Cultivation
摘要
Abstract
Objective] To explore the suitable sowing amount of direct seeding under no-tillage and plowing cultivation in the field of hybrid rape.[Method] The split plot design experiment was carried out in different cultivation methods,varieties and sowing amount,and the correlation between plant characters and seeding quantity was calculated .[ Result ] Yield of ploughing direct seeding was higher than no-tillage direct see-ding,the average yield was 5.38%,which increased significantly.But ploughing direct seeding cultivation had equal seeding amount to no-tillage direct cultivation.Although the former showed a slight increase in production ,the increase in output value was not enough to make up for the labor cost of plowing.The yield difference was not significant between different cultivars.Combining with the existing researches,the seeding quantity of direct seeding rape was 3.8-4.5 kg/hm2 .With the increase of seeding quantity,effective branch height of rape enhanced,plant height slightly de-creased,the length of the main inflorescence became short ,the effective pod number per plant and effective branch number per plant decreased and 1000-grain weight reduced.[Conclusion] This research provides references for the further improvement of direct seeding technology of rape.关键词
