In recent years, with the support of the state's policy of revitalizing the soybean industry, a large number of new varieties of high-yield and high-quality soybeans have successively passed the examination and approval of the state and provinces, municipalities and autonomous regions, making outstanding contributions to the development of soybeans in China. Today I will introduce you to a new variety of ultra-high yield soybeans. This variety is Nannong 47.
Validation status
Nannong 47 is a new soybean variety selected and bred by the National Soybean Improvement Center of Nanjing Agricultural University after 10 years, which was approved by Jiangsu Province in 2019, approved by Henan Province in 2020, and introduced in Anhui and Shandong provinces for the record. It has become one of the most popular new varieties of high-quality soybeans among farmers in the Huanghuaihai East Area.

(1) Moderate maturity: Nannong 47 is planted in Henan, which is a limited pod pod variety, planted in the Huang-Huai-Hai region, with an average growth period of 107 to 109 days, and does not delay the sowing of stubble crops.
(2) Good toppling resistance: Nannong 47 plants are compact, the average plant height is 95 cm, the height of the bottom pod is 15 to 20 cm, the stem base is thick, the root system is developed, the grip is firm, and it is not easy to lodging.
(3) Good yield: Nannong 47 has good adaptability, strong disaster resistance, in Henan region test, the average yield of 492 jin per mu, production test, average mu yield of 432 jin, production of large-scale planting, average mu yield of 500 ~ 600 jin, 2020 production acceptance, the highest mu yield of 674.8 kg. Stable production is good, and the potential for increasing production is large.
(4) Good quality: Nannong 47 grains are medium to large, uniform in size, 100 grains weigh 19 to 20 grams, the grains are round and full, and the commerciality is good. The general protein content is 42 to 45%, and the crude fat content is 18.69%, which belongs to the high protein soybean quality and is particularly suitable for processing tofu.
Cultivation technique points
Nannong 47 is suitable for planting in Henan, Jiangsu, Anhui, Shandong and other provinces, the best sowing period is in mid-to-late June, taking 40 to 45 cm equal row spacing or 50 to 30 cm wide and narrow row planting. Before planting, 15 to 20 kg of 45% three-element compound fertilizer per mu, 12,000 to 15,000 plants per mu of seedlings, and 2 to 4 pieces of soybean at the compound leaf stage were sprayed with chemical herbicide. Do a good job in field weed control, control the first flowering of soybeans, and pay attention to the control of pests such as bean moths during the flowering stage and drum stage of soybeans.
