Jidou 11 (soybean)

Jidou 11 (Cang 8110-251) was selected by Cangzhou Academy of Agricultural and Forestry Sciences of Hebei Province in 1981 using B99 as female parent and Qihuang 1 as male parent.

The characteristics of this variety are erect growth, plant height 60~70cm, main stem 12-14 nodes, 3 effective branches and plant shape convergence. The internodes are short, the pods are dense, and the leaves are ovoid, medium size. White flowers, gray hairs, limited podding habits, effective pods per plant 3035, with an average of 2.2 seeds per pod. The seed coat is oval and yellow, the seed coat is shimmer, the navel is yellow, there is no purple and brown spot, the insect feeding rate is low, and the weight of 100 seeds is 1820g. The protein content is 41.7% and the fat content is 20.1%. The growth period is 85-90 days, which is an early-maturing summer sowing variety with moderate disease resistance, early tolerance and barren tolerance. Its outstanding characteristics are: early maturity, dwarf and lodging resistance, pod density, high yield and stability.

Participated in the new strain identification from 1987 to 1988, the average yield per mu in two years was 164.1kg, which was 11.6% higher than that of the control Jidou 6. In 1989, the yield comparison experiment showed that the yield per mu was 201.3kg, which was 18.7% higher than that of the control Jidou 6. Participated in the regional trial of summer soybean in Hebei Province from 1990 to 1991, the average yield of 148.3kg per mu was 14 points in two years, which increased by 17.8% over the control Jidou 6, ranking first among the 9 tested varieties. In 1991, we participated in the demonstration experiment of summer soybean production in Hebei Province. The average yield per mu of the five pilot projects was 1.8% lower than that of the control Jidou 6. In the same year, the yield of 164.5kg per mu of the large area demonstration field of Xinhe Farm in Hebei Province was 20.3% higher than that of the control Jidou 6. In 1992, the drought in Cangzhou area was serious, and the average yield per mu of summer sowing in Haixing County was 182.0kg.

Regional and technical Jidou 11 is suitable for summer sowing in south-central Hebei Province, northern Shandong Province, Tianjin, Beijing and other places. 1. Fine soil preparation to ensure sowing quality, in order to achieve one sowing of the whole seedling. two。 Timely early sowing, generally before June 25, in a special year sowing date postponed to the end of June, early July can still get a better harvest. 3. 15000 ~ 17000 strains of bacteria per mu of fertile soil and 17000 ~ 20000 strains of seedlings per mu of medium or low fertility soil can be planted in wide and narrow rows of 50 × 30cm or 40cm. 4. It is best to apply 1250~1500kg farm manure as base fertilizer before sowing, swindle 5kg compound fertilizer to make seed fertilizer during sowing, apply compound fertilizer 10~15kg per mu at early flowering stage, and spray micro-fertilizer at flowering to grain filling stage. 5. Flowering and pod filling period, such as serious drought should be timely irrigation, such as too much Rain Water, we must pay attention to timely drainage to prevent waterlogging damage. 6. Routine field management was carried out during the whole growth period.
