- 摘要:
- 为解决黑龙江省半湿润区玉米生产中秸秆还田率低、适合机收玉米品种少、籽粒机收率低等问题,在秸秆碎混还田全程机械化生产模式下对4个玉米品种进行了产量及其构成因子的研究,筛选适宜该模式生产的玉米品种。结果表明:4个参试品种中和育189产量较高,产量构成因子综合表现较好,更适宜在黑龙江省中南部半湿润区进行秸秆碎混还田模式生产。
- Abstract:
- In order to solve the problems of low straw returning rate in maize production in semi-humid area of Heilongjiang Province,fewer maize varieties suitable for machine harvesting and low grain machine yield.The yield and components of four maize varieties were studied under the whole mechanized production mode of straw shredding and returning to the field,and the maize varieties suitable for this mode were screened.The results showed that Heyu 189 had higher yield and better comprehensive performance of yield components.It was more suitable for straw shredding and returning mode in semi-humid area of South-Central Heilongjiang Province.
