What are the high-yield soybean seeds?

Soybean, commonly known as soybeans, is an annual herb of leguminous soybeans, which is native to China and is cultivated all over China. It is also one of the important food crops in China. It has been widely cultivated all over the world and has been cultivated for 5000 years. It is most commonly used to make all kinds of soybean products, extract soybean oil, brew soy sauce and extract protein. Let's take a look at the high-yield soybean seeds.

[characteristics] the main stem mainly bears pods, and the plant height is about 70 cm. Pointed leaves, purple flowers, gray hairs, pods brown. The seed is round, the seed coat is yellow, glossy, yellow navel, 100 grains weigh 17.1 grams. In the suitable area, the number of childbearing days is about 117 days, and the active accumulated temperature is about 2350 ℃. It was resistant to disease and lodging in the field, inoculated and identified resistant to gray spot, moderately resistant to mosaic virus strain 1 and susceptible strain 3.

[yield] participated in the regional trial of mid-early maturity group varieties of northern spring soybean from 2011 to 2012, the average yield per hectare was 2833.5 kg, 2.8% higher than that of the control varieties. In the production test in 2013, the average yield per hectare was 3010.5 kg, 11.1% higher than that of the control variety.

[cultivation] generally sowing in the first and middle of May, planting 25.0 ~ 350000 seedlings per hectare under ridge three cultivation and 35.0 ~ 400000 seedlings under close planting. In general, 150 kg of diammonium phosphate, 50 kg of potassium sulfate and 40 kg of urea were applied per hectare, and special foliar fertilizer for soybean was sprayed twice at flowering and podding stage.

[characteristics] the growth period of summer sowing is about 100 days, and that of spring sowing is 121 days. The plant height is 75-90 cm, the number of effective branches is 1-2, oval leaves, white flowers, gray hairs, mature pods are brown, pod-bearing habits are subfinite, round grains, yellow seed coat, yellow navel, 100-grain weight 18-22 grams. It was moderately resistant to soybean mosaic virus and gray spot, and moderately susceptible to soybean cyst nematode disease.

[yield] participated in the regional trial of summer soybean varieties in the north of Huang-Huai-Hai in 2004, the average yield per mu was 206.0 kg, 19.3% higher than that of the control precocious 18. In 2005, the average yield per mu was 204.3 kg, which was 5.6% higher than that of the control Jidou 12. The average yield per mu in the two-year regional trial was 205.1 kg. In the production test in 2005, the average yield per mu was 219.1 kg, 5.8% higher than that of the control Jidou 12.

[cultivation] 2000kg / mu of rotten organic fertilizer was applied before sowing, 4kg / mu of phosphorus and potassium fertilizer was applied as seed fertilizer, and 12000 ~ 16000 seedlings were protected per mu. Attention should be paid to drought prevention in branching stage, flowering and pod stage and seed filling stage.

[characteristics] limited podding habits, plant type convergence. The growth period was 106 days, which was 3 days later than that of Hedou 12. Plant height 79.6 cm, effective branches 2.3, main stem 16 nodes, round leaves, white flowers, brown hairs, deciduous leaves, undehiscent pods, 104 grains per plant, seeds oval, seed coat yellow, glossy, navel black, 100-grain weight 19.3 grams.

[yield] in the regional trials of summer soybean varieties in the province from 2012 to 2013, the average yield per mu in two years was 224.4 kg, which was 7.7% higher than that of the control Hedou 12, and the average yield per mu in the production test in 2014 was 244.3 kg, which was 8.4% higher than that of the control Hedou 12.

[cultivation] the suitable density is 13000-15000 plants per mu, and other management measures are the same as those in the general field, which are planted and utilized as summer soybean varieties in central Shandong, southern Shandong and southwestern Shandong.

[characteristics] the plant height is 90cm and 100cm, the plant type converges, the leaves are round, dark green, brown fluffy, white flowers, infinite pod habit. Seed coat yellow, glossy, black navel. 100 grains weigh 21g, containing 40.11% protein and 18.84% fat. The growth period of spring sowing is 128-133 days, and the plant has strong growth, many branches, dense pods, early filling and large seeds. Strong ability to resist drought and virus, resistant to red spiders.

[yield] participated in the national regional test from 1999 to 2000, the average yield per mu was 168.6 kg, 11.5% higher than that of the control Tiefeng 27. Participated in the national regional test in 2000, the average yield per mu was 169.7 kg, 1.9% higher than that of the control. In 2000, the average yield per mu was 193.2 kg, 2.4% higher than that of the control.

[cultivation] Spring sowing from late April to early May, the sowing rate per mu was 4: 6 kg, and the planting density was 8000-10000 plants per mu. Wheat stubble re-sowing, sowing in the first ten days of June to the middle of June, sowing rate per mu is about 7.5kg, leaving about 16000 seedlings per mu, we should pay attention to time and soil moisture sowing.
