Suinong 14 (soybean)
This variety is a new mid-maturing spring soybean variety bred by Suihua Institute of Agricultural Sciences, Heilongjiang Academy of Agricultural Sciences, using Hefeng 25 / Suinong 8 as material. The growth days of Suinong 14 were about 120 days, and the active accumulated temperature was about 2486 ℃. Sub-limited podding habits, high and high plants, few branches, dense pods on the main stem, purple flowers, long leaves, thick green leaves, gray hairs. The internodes are short, the pods are dense, and there are more than 3 or 4 grains. The seed is round, the seed coat is bright yellow, the navel is colorless, and the weight of 100 seeds is 21g to 22g.

New techniques for high yield of soybean with four changes and one increase
The traditional ploughing and sowing method of planting soybean, the row is narrow, too dense, coupled with many other reasons, the yield has always hovered around 100~150kg. After years of experimental research, we have explored a new way to increase soybean production by more than 40%, that is, "four changes and one increase" technology. In order to increase soybean yield, we should not only select new varieties with high quality and high yield, but also pay attention to crop rotation. According to the experiment, after continuous cropping for many years, soybean showed slow growth, short plant, yellow lower leaves, early defoliation, few pods and small seeds. The experiment also proved that continuous cropping (even
