Xingnong No.2 soybean

Xingnong No. 2 soybean was successfully cultivated by Tian Suhua, a farmer agronomist, after 5 years. Shandong Shanxian Agricultural Technology Application Research Institute has tested and demonstrated in more than 1200 sites in 13 provinces and regions for 4 consecutive years, with a yield of 15 ha (1 mu), 400 kg in spring sowing and 300 kg in summer sowing. The strain has the advantages of neat growth, good lodging resistance, a large number of nodes in the main stem, good podding and high yield, high yield potential, high and stable yield. It was identified by experts on January 15, 2001. The characteristics are sub-limited podding, mid-early maturity, 130 days of spring sowing and 95-100 days of summer sowing. The root system is well developed and the growth potential is prosperous. The leaf shape distribution is reasonable, the middle and lower part is heart-shaped, the upper part is lanceolate. The leaf photosynthetic potential is strong, and determined by Shandong Agricultural University, the photosynthetic rate and other related indexes have obvious advantages over the control varieties. When the third true leaf unfolds, it begins to blossom and bear pods. The flower is white, the florescence is long, the flower quantity is 2 or 3 times more than the general variety, the podding ability is good, the high yield and stable yield is good, and the yield potential is great. The general plant height is 120cm to 160cm, self-capping, stout and hard stem, high resistance to lodging. Densely planted unbranched, sparsely planted 3-6 branches, clustered pods along the stalk, 4-6 per cluster, as many as 8, from the bottom to the top of the bean plant were densely covered with pods, 60-90 pods per plant, up to more than 300 pods. 3 pods accounted for more than 90%. The speed of grouting is fast, the maturity is consistent, and the dried pods are not naturally fried. The seeds are round, yellow, light brown navel and weigh 18-20 grams. It can be planted as far as Jiangxi Province and Inner Mongolia in the south, with strong resistance to stress and disaster, few diseases and insect pests, drought and waterlogging resistance and continuous cropping. The quality characteristics tested by Shandong Agricultural University showed that the protein content was 40.1%, the fat content was 18.6%, and the content of unsaturated fatty acids was high, and the contents of linoleic acid and linolenic acid accounted for 54.14% and 6.2% of the total fatty acids, respectively. It belongs to high nutrition and storage resistant soybean. The main points of cultivation have a wide range of adaptation and a wide sowing period, so it is suitable to be planted in medium and high fertilizer fields, and can be sown in spring and summer. In general, 12000 plants were planted in 15 hectares and 20, 000 plants in barren fields. The row spacing of spring sowing is 80 cm, that of summer sowing is about 60 cm, and the plant spacing is 5-8 cm. After wheat harvest, you can grab stubble and sow seeds.
