Why the soybean root nodule is few and small?
There are nodules on the root of soybean, which can be used for symbiotic nitrogen fixation, which is an important source of nitrogen for legume crops. But in actual production, sometimes the root nodules of soybean are few and small, what is the cause of this? Expert: when you encounter particularly serious symptoms, you should first think that it may be caused by the lack of trace element molybdenum. Because molybdenum is an essential trace element for nitrogen fixation in root nodules of legume crops, the absolute content of general crops is 1/1000000, while the molybdenum requirement of soybean is dozens of times higher than that of other crops. The main function of molybdenum is to promote the shape of soybean nodules.

How to prevent low yield from planting soybeans?
How to prevent low yield from planting soybeans? Please give guidance in the current agricultural production, growing soybeans basically do not apply fertilizer (especially in summer soybean producing areas). The main reason is that most people think that soybeans can fix nitrogen, grow soybeans without fertilization, and leave a certain amount of nitrogen for subsequent crops. It is precisely because of this misunderstanding that leads to health.

Matching techniques for high yield of improved varieties and methods of soybean
1. Sowing at the right time, select the varieties with high potential to increase production in this area, and sow at the right time. Use herbicides before sowing, and then use herbicides according to grass conditions after sowing. Sowing time, spring soybeans from the end of April to the beginning of May, sowing depth of 5 cm, sowing must pay great attention to soil moisture. The main conditions for soybean seed germination are water, temperature and oxygen. ① moisture: seed germination is first of all water absorption, so water is an important factor in germination. The amount of water absorbed by seeds during germination is equivalent to 1.21 of the seed weight.

Make good use of base fertilizer when sowing peanuts and soybeans
Some farmers do not apply any fertilizer when sowing these crops, which is one of the important reasons that restrict the yield of peanuts and soybeans. Although legume crops can use the nitrogen fixation function of rhizobium to absorb nitrogen in the air to supplement nutrients, but the amount of nitrogen fixation is only 2 × 3-1 × 2, and phosphorus and potassium nutrients.

Fertilization Technology of Spring Peanut
Calcium can promote pod formation, reduce empty pods and increase the number of full fruits, and the application of calcareous fertilizer lime in acidic soil can also reduce soil acidity and is beneficial to nodule nitrogen fixation. Therefore, calcium fertilizer can improve the yield and quality of peanut. Peanut lacks calcium, the plant grows slowly, the root thin seedling is weak, the edge and leaf surface of the old leaf will appear.

Apply sufficient base fertilizer to mung bean
Although mung bean rhizobium has the ability of nitrogen fixation, the application of farm fertilizer and phosphorus and potassium fertilizer can obviously increase the yield. Before sowing, 2500 kg of farm manure, 20 kg of phosphate fertilizer and 1 kg of biological potash fertilizer were applied as base fertilizer per mu. If the field that is too late to apply base fertilizer, in the early stage of growth, that is, branching, the first flowering stage, the application of three-yuan compound fertilizer 7.5 thousand per mu.

What if something like this happens to your succulent plant? Tell me about it.
Going back to nodules and fixing nitrogen, the significance of the theory of convergence evolution is that many plants are poor because of their living environment, lack of enough nitrogen in the soil, and finally, the ability to cooperate with rhizobia has evolved unexpectedly. Plant nitrogen fixation is another kind of fake.

Main Technical points of fertilization for Peanut
How do peanuts perform when they are short of evidence? How to prevent and cure? The main results are as follows: (1) the characteristics of deficiency: when peanut is deficient in aluminum, the plant is short and the leaves are small and thin, showing yellowish green, which is the same as the typical symptoms of nitrogen deficiency. If the above symptoms occur when the nitrogen nutrition is sufficient, the problem of steel deficiency should be taken into account. (2) Prevention and control measures: potassium lead acid.
