Daytime management technology of soybean
1. Seedling as early as possible. The peasant proverb says, "if the seedlings are an inch earlier, there will be a crop of dung on top." Interseedling is particularly important for mechanical strip sowing or big ploughing to plant peas. If the distribution of seedlings is uniform and reasonable, the phenomenon of seedling bullying can be prevented in time, which can reduce the consumption of soil nutrients and water, make the development of seedlings balanced and healthy, so as to increase the yield of soybean. The interseedling is generally carried out in the period of two opposite single leaves spreading and compound leaves appearing in the seedling stage of soybean. Diseased seedlings, weak seedlings, seedlings and miscellaneous seedlings should be removed between seedlings. 2. Ploughing and weeding. Generally required to achieve three shovels and three boring.
