Where Huangzhong 37 is suitable for planting, briefly introduce it.

Huangzhong 37 conforms to the national soybean variety approval standard and is suitable for summer sowing and planting in Beijing, Tianjin, Jizhong, Lubei, Jianghuai hilly area and Huaibei area. Zhonghuang 37 is a soybean seed bred by Institute of Crop Science, Chinese Academy of Agricultural Sciences, with an average growth period of 1 10 days. Resistant to soybean mosaic virus SC3, SC8, SC 1 1, SC 13, moderately sensitive cyst nematode. The suitable sowing date of Zhonghuang 37 is in the middle and early June, and the suitable density is 1.3- 1.5 million plants/mu. Suitable soil is medium and high fertility land.

1. Where is Huangzhong 37 suitable for planting?

Soybean varieties 1 and Zhonghuang 37 are suitable for summer sowing and planting in Beijing, Tianjin, central Hebei, northern Shandong, Jianghuai hilly area and Huaibei area.

2. Zhonghuang37 is the Institute of Crop Science, Chinese Academy of Agricultural Sciences, so 95B020? Soybean seeds bred by precocious 18 passed the national soybean variety approval standard in 2006, and the approval number was 2006003.

Two. Introduction to Huang Zhong 37

1, growth period: the average growth period of huangzhong 37 is 1 10 days.

2. Plant characteristics: the plant height is 83.8 cm, the number of effective branches is 2. 1, the number of effective pods per plant is 37.0, the grain weight per plant is 20.3 g, the grain number per plant is 82.8, and the 100-grain weight is 27.3 g. Oval leaves, white flowers, gray hairs, limited pod-setting habits and plant type convergence. The seed coat is yellow, shiny, umbilical brown, and the grain is oval.

3. Resistance performance: resistant to soybean mosaic virus SC3, SC8, SC 1 1, SC 13 strains, intermediate race of cysticercus cellulosae 1. According to the resistance identification of National Soybean Improvement Center (Nanjing), in 2007, the prevalent strain of soybean mosaic virus SC3 was resistant (disease index 4%) and SC7 was moderately resistant (disease index 34%). In 2008, SC3 showed moderate resistance (disease index 28%) and SC7 showed moderate resistance (disease index 28%).

4. Quality performance: In 2007, the soybean and bean products quality supervision, inspection and testing center (Jiamusi) of the Ministry of Agriculture detected that crude protein (dry basis) was 44.44% and crude fat (dry basis) was 20.23%. In 2008, crude protein (dry basis) was 48.28% and crude fat (dry basis) was 20.28%.

5. Yield performance: In 2004, I participated in the regional test of summer soybean varieties in the north of Huanghuai, with an average yield of 206.7 kg per mu, which was 9.7% higher than that of early maturity 18 (extremely significant); In 2005, the average yield per mu was 2 18.7 kg, which was 3.0% higher than that of Jidu 12 (extremely significant). The average yield per mu in two-year regional trials was 2 12.7 kg. In 2005, the average yield per mu was 214.8kg, which was 3.8% higher than that of Jidu 12.

6. Planting points: The suitable sowing date is in the middle and early June, the suitable density is 0/.3-1.5 million plants per mu, and the suitable soil is medium and high fertility land. Pay attention to squatting seedlings at seedling stage, pay attention to drought prevention at early flowering stage and filling stage, and intertillage 2-3 times before closing the ridge.
