Abstract
In view of the problem that alfalfa flowering time did not meet insect activity,alfalfa flowering time was adjusted and controlled by cutting to improve the pollination efficiency and to study the effect on seed yield and constitution factors.The results showed that:(1) The flowering time was put off obviously by cutting,and the pollination efficiency was improved distinctly.The visiting flower frequency increased from 23 times/10m2·d(control) to 180 times/10m2·d,the pod set rate/per raceme was improved from 17.12±2.83 to 84.1±1.21 and number of seeds per pod was improved from 3.94±0.31 to 5.31±0.22.The mean of pod set rate/per raceme in entire flowering stage was improved from 43.77% to 59.43%.(2)The correlations between the seed yield and some agronomical traits was as follows: number of raceme/per branch number of pod/ per branch number of seed per pod pod set rate/per raceme number of branch number of flower/per raceme.There were true regression relationships between the seed yield and number of raceme/ per branch(X1) and pod set rate/per raceme(X2),by the multiple regression analysis: Y=-1.735+0.034 X1+0.036 X2(R=0.788).(3) Flowering time can be put off obviously by cutting at appropriate time and the seed yield can be improved.Appropriate cutting time is that the growing time was as long as in the condition of flowering time being put off.
