春大豆播种后,常因雨水过多造成发芽率不高、出苗不整齐甚至烂种的后果,成为生产上的一大障碍。育苗移栽则是消除这种障碍的好办法。 实践表明,春大豆育苗移栽具有多方面的好处。首先,由于育苗采用薄膜覆盖,减少了外界不良环境的影响,因而可以提早播种,缓解前后茬的季节矛盾,且能保证发芽率高,出苗整齐;其次,集中育苗便于苗期管理,有利于培育壮苗;三是能节约用种量百分之三十左右,增产百分之十五至二十,因而能大大提高劳动生产率和经济效益。其主要技术要求有以下四点:
Spring soybean sowing, often due to excessive rainfall caused by the germination rate is not high, the emergence of irregular or even rotten consequences, become a major obstacle in production. Seedling transplanting is a good way to eliminate this disorder. Practice shows that spring soybean seedling transplanting has many benefits. First of all, because of the thin film covered seedlings, reducing the adverse environmental impact of the outside world, which can be sown early to alleviate the seasonal contradictions before and after the crop, and to ensure high germination rate, emergence and tidy; Second, the centralized nursery is conducive to nursery management Strong seedlings; third is to save about 30 percent of the amount of seeds, an increase of 15 to 20 percent, which can greatly improve labor productivity and economic benefits. The main technical requirements have the following four points:
