The kidney bean flower is small, and the flower is thin and the flower is difficult because the flower is not well differentiated. The main reasons why cowpea does not hatch are as follows: Acid Soldering Flux Paste,Soldering Paste Flux,Solder Flux Paste,Flux Soldering Paste NINGBO XIHAN TIN SOLDER CO.,LTD. , https://www.soldertop.com
What if the cowpea does not pod?
1. The temperature in the shed is too low, which directly affects the normal differentiation of the flower buds, or causes the incomplete development of the flower organs to appear infertile flowers, and the flowers cannot be fertilized and fall off.
2. The soil and air in the shed are too dry, the pollen is prematurely degraded, and the stigma is dry. This is also the reason why you can't sit still. It is recommended not to fertilize, but only water. Because the cowpeas at this time are not prosperous but not weak, the fertilizer is easy to cause prolongation, which will weaken the flower bud differentiation.
3, cowpea planting is too dense, the mutual shading between the lines is quite serious. It is recommended to do some leaf thinning treatment properly, and pay attention to reasonable close planting in the future planting. Under the condition of constant plant spacing of 40cm, two seedlings of each hole can be changed into two seedlings, or the plant spacing is 45cm. If the planting is too dense, the lack of light can cause the cowpea flower pod to be insufficiently nutritious and fall off during development.
In order to improve the situation of less cowpea flowers and difficult flowers, in addition to reasonable field operations, some agents containing molybdenum and boron may be sprayed.
