AM89-9 Soybean Variety Introduction and Main Characteristics

Growing Techniques 0 views
AM89-9 soybean was developed in 1989 by sexual hybridization from flat-stem soybean. After 10 years of breeding, trial planting and strict purification and rejuvenation selection, it stood out in the soybean kingdom and became a pearl in the soybean kingdom. Since its promotion in 1996, it has consistently won people's affection and is called "the king of kings among soybeans". Characteristics: growth period 115-120 days, 100-seed weight 20-21 grams (100-seed weight of foundation seed 18-19 grams). Plant height 100 cm. Pods are mainly set on the main stem, which generally has 22-25 nodes, with an average internode length of 4-6 cm. Pod-setting position is low, apical dominance is strong, average pods per plant 130, tolerant of continuous and repeated cropping, strong stress resistance, good yielding ability. Yield performance: on plots with good fertilizer and water conditions, yield per mu can reach 550-600 jin. In 1996, in Chentun Village, Dashi Township, Beining City, it reached as high as 598 jin. Adaptation range: Liaoning, Jilin and southern Heilongjiang. Areas with fertile soil are best. Cultivation points: seeding rate 3-4 kg per mu. In Liaoning, this variety is generally sown in early May, and sparse planting is advisable, with a plant spacing of 10-13 cm. It likes fertilizer and water; apply 20,000-30,000 jin of farmyard manure per hectare as base fertilizer, with N:P:K at 4:10:6. During the growth period, hoe and ridge in time, and spray chlormequat to control plant height at about 1 m.
