Effects of hemp bean rotation on crop agronomic traits and yield
In order to explore a suitable farmland rotation system for promotion in Heilongjiang Province,this experiment conducted continuous cropping and rotation treatments on hemp and soybean,the effects of different treatments on the agronomic traits,yield,and economic benefits of soybean and hemp were analyzed.The results showed that crop rotation increased the plant height,stem thickness,number of main stem nodes,effective nodes,number of effective pods per plant,plant weight,plant stem weight,plant pod weight,plant pod skin weight,plant grain number,plant grain weight,hundred grain weight of soybean,as well as the plant height,stem thickness,branching height,branching number,plant grain number,plant grain weight,and thousand grain weight of hemp,while reducing the bottom pod height and number of deflated pods per plant of soybean.Relevant analysis showed that,except for the height of bottom pods and the number of flattened pods per plant,soybean had a negative correlation with yield,while other agronomic traits were positively correlated with yield.The height and number of grains per plant of hemp were significantly positively correlated with yield(P<0.01).Crop rotation had increased the yield and output value of soybeans and hemp,with a net income of 1 877.95 and 2 636.40 yuan/hm2,respectively,compared to continuous cropping.
