Vernalization time and planting density test of broad bean
In order to advance the picking period,extend the picking cycle of broad beans,and increase the planting efficiency of fresh broad beans,the vernalization treatment time and planting density experiments of broad beans were carried out.The results showed that vernalization of broad bean at 4℃for 20-30 days could significantly advance the picking period of broad bean,extend the picking cycle,significantly increase the number of pods per plant and 100 pod weight,and thus increase the yield of fresh pods.Vernalization treatment for 30 days could significantly increase the number of grains per pod and pod length,and reduce the node position of the first flower.Reducing the planting density could increase the number of pods and branches per plant,but did not have a significant effect on yield.Planting 1 500 plants(plant spacing 35 cm)at 667 m2 is the best choice,which can save the amount of seeds,reduce production costs and labor without reducing yield,and improve the quality of fresh broad beans.This test can provide technical support for the production of broad beans in Wenling City.
