Abstract:
In order to study the effects of planting patterns on growth and yield of soybean, the field comparative experiment was conducted at Daxijiang Farm in Heilongjiang province in 2019 .Seven planting patterns were designed to analyze the leaf area index, agronomic traits and yield components of soybean.The results showed that the yield of the four rows with unequal-row spacing on ridge pattern was the highest as 3 414.65 kg?ha-1, followed was the wide ridge sowing and small ridge management pattern as 3 384.82 kg?ha-1. Compared with the three rows on ridge planting pattern used in the experimental farm, the yield were increased by 7.6% and 6.7% respectively. There were significant difference among planting patterns in soybean yield. The leaf area index of the four rows with equal row spacing was the highest as 2.87, which was significantly different from other planting patterns. The four rows with unequal-row spacing pattern had the highest plant height as 67.2 cm, and the podding height was also the highest as 16.85 cm. The three rows on ridge pattern had the thickest plant as 5.22 cm and the largest number of seeds per plant as 52.06, but the lowest 100-seed weight as 18.63 g of all planting patterns. The wide ridge sowing and small ridge management pattern had the largest number of harvested plants, reaching 35.7 plants?m-3. The conventional planting pattern had the highest 100-seed weight of 19.85 g, and other indicators were at medium levels. Correlation analyses indicated that soybean yield was highly significant correlated with stem diameter, pods per plant, seeds per plant and seed weight per plant, with correlation coefficients of 0.464,0.762,0.750 and 0.970, respectively. The four rows with unequal-row spacing pattern was an ideal high-yield pattern, with the highest yield, and the other indicators also perform well.
