Cultivation and Management methods of Jinyi 30 Soybean

Jinyi No. 30, a new high-yield soybean variety, was selected by the Institute of crop Genetics of our Provincial Academy of Agricultural Sciences after many years of crossbreeding. After the variety matured, the plant height can reach 85 ~ 102cm, the root system is developed, the rhizome is strong, the plant shape is compact, the grain is deep yellow and shiny, and the 100-grain weight is about 22.2 grams. It is a high-quality mid-and late-maturing soybean variety.

Zhang Haisheng (Associate Research fellow, Institute of crop Genetics, Shanxi Academy of Agricultural Sciences): drought resistance, disease resistance, oil yield and quality.

Commentary: the growth period of Jinyi 30 is about 135 days in spring sowing and 105 days in summer sowing, which is more suitable for summer sowing in the late ripening area of spring sowing soybean in the north and in the middle and north of Huangwei Sea. Take our province as an example, the spring sowing time for farmers' seed selection can be carried out during the period from late April to early May, and the summer sowing time is appropriate from June 1 to June 15.

Interview: talking about the main points of cultivation

Commentary: according to experts, Jinyi 30 is a high-fat variety. In addition to being used for oil processing, soybean meal can also be processed into concentrate feed, and its protein content can exceed 40%.

Interview; talk about output.

Commentary: expert hint: the cultivation points of Jinyi 30 mainly include: applying farm manure 2000 kg / mu and phosphorus nitrate 25-30 kg / mu before sowing, sowing mode: equal row spacing is the main sowing method, keeping seedlings per plant is better, sowing depth should be controlled at 3-5 cm, suitable density: 6000 plants / mu for spring sowing and 10000 plants / mu for summer sowing, chemical control time. When the plant grows to 6-8 compound leaves, paclobutrazol can be used for chemical control in time to ensure plant yield and improve soybean quality.
