Brief introduction of am89-9 soybean
AM89-9 soybean was made by sexual hybridization of flat stem soybean in 1989. After 10 years of cultivation, trial planting and strict purification and rejuvenation, it stands out in the soybean kingdom and becomes a pearl in the soybean kingdom. Since it was promoted in 1996, it has been loved by the common people and is known as the "king of soybean kings". Characteristics: the growth period is 115ml / 120d, and the weight of 100 seeds is 20ml / 100g (18,19g / 100 seeds). The plant is 100 cm high. The main stem mainly bears pods, and the main stem is generally 22 Mel 25 nodes, with an average node length of 4 Mel 6 cm. The pod-bearing position is low, the apical dominance is strong, with an average of 130 pods per plant, which is resistant to continuous cropping, strong stress resistance and good yield. Yield performance: the yield per mu of land with good fertilizer and water can reach 550 muri 600 jin. In 1996, Chen Tun Village, Dashi Township, Beining City, reached 598 jin. Scope of adaptation: Liaoning, Jilin and southern Heilongjiang. The zone with rich soil is the best. Main points of cultivation: 3ml / mu, 4kg. This variety is generally sown at the beginning of May in Liaoning area and should be sparsely planted with a distance of 10 Mel 13 cm. Like fertilizer and water, 20-30 thousand jin of farm manure per hectare is used as base fertilizer, and the N:P:K is 4:10:6. The growth period was shoveled in time, and the plant height was about 1 meter by spraying Daizhuangsu.

Instructions for the use of 4gd-2 soybean sun cutter
Heilongjiang Province is the main producing area of soybean in China, with more than 30% of the total planting area of soybean. for many years, artificial knives have been used to harvest soybeans, which not only has low daily efficiency and long harvest period, but also affects the timely operation of autumn ploughing and autumn soil preparation. Although the farm uses large-scale machinery for cutting and drying, the loss rate is still between 8-10%. Due to the delay in the harvest period, it is combined with the late maturity of soybean. The fried soybean clip is even more serious. With the reform of the farm and rural economic system, small four-wheeled tractors
