Many people apply boron fertilizer to soybeans. What are the functions of boron fertilizer?

At present, many farmers pay more attention to the use of boron fertilizer and molybdenum fertilizer to grow soybeans. In fact, spraying boron fertilizer and molybdenum fertilizer not only on soybeans but also on other legume crops can have a good effect on increasing production and improving quality. However, many farmers are not good at using it. The farmer teacher will talk about this topic in detail below.

1. What are the benefits of boron fertilizer and molybdenum fertilizer to soybean growth?

Boron fertilizer and molybdenum fertilizer have a great impact on the growth and development of soybeans. Molybdenum fertilizer affects the nitrogenase activity of soybean rhizobia. If molybdenum is deficient, soybean root nodules will be stunted, showing a normal nitrogen deficiency, while boron will affect soybean flowering and fruiting. Boron aids in flowering, transport of photosynthetic products to fruits, reproductive growth, and pollination and fertilization.

2. What is the magic power of boron-molybdenum mixture?

Experimental data show that the combined application of boron and molybdenum fertilizers has a better effect on soybean plant height, stem diameter, branch number, pod number per plant and effective pod number than the blank control group. The number of soybean branches and the number of effective pods are related to the utilization of boron, and the utilization of boron is related to the flowering and pollination efficiency of boron fertilizer and the flow of photosynthetic products to seeds. Molybdenum fertilizer is an indispensable trace element for nitrogen fixation by rhizobia in leguminous crops. Spraying molybdenum fertilizer can increase the number of rhizobia, improve nitrogen fixation ability, increase the number of branches and pods, and effectively increase soybean yield. Boron is conducive to transporting photosynthetic products to seeds and strengthening seeds. Through boron and molybdenum fertilizer spraying tests, the yield increase effect of boron and molybdenum mixture is more obvious.

The results show that boron spraying and molybdenum spraying increase production by 8.9 to 13.0. Below this level, molybdenum spraying or boron spraying alone increases production. The effect of spraying boron and molybdenum fertilizers together is significantly better than spraying boron or molybdenum alone, indicating that boron and molybdenum can coordinately promote the growth of soybeans.

3. How to supplement boron and molybdenum?

Molybdenum is generally deficient in soybean growing areas such as Northeast China. In addition, many farmers do not pay attention to the application of molybdenum fertilizer when planting soybeans, which will take away some trace elements after the soybeans are harvested. Therefore, it is recommended to supplement the molybdenum source bank chelated with sugar alcohol, which can quickly achieve the effect of supplementing molybdenum element. Boron fertilizer can use cold water instant boron source bank, which has higher absorption efficiency. Adding the two together, the cost per mu is less than 2 yuan, which is a considerable increase in production. It is recommended to spray the boron source pool and molybdenum source pool 2-3 times during the seedling, flowering and pod-bearing stages. Generally, 20 ml of molybdenum source pool, 20 g of boron source pool, 30-40 kg of water, and 30-60 kg of water per mu. Molybdenum source bank, high-purity sugar alcohol chelated molybdenum fertilizer, can be quickly absorbed by plants. It is suitable for supplementing molybdenum elements in soybeans, peanuts and other beans, which helps to improve nitrogen fixation efficiency and increase bean yields. When spraying boron molybdenum fertilizer, it can be mixed with other drugs and fertilizers, and can also be used in conjunction with kendole natural brassinosteroid. Kendole can improve photosynthesis efficiency, help transport photosynthetic products into grains, reduce the impact of bad weather on soybean growth, and help increase yields.
