What are the high-yield tips for peanuts? In fact, planting peanuts for high yields is the expectation of every peanut grower and farmer. Everyone knows that there are always some places in the country that cause peanut yield decline due to weather. Today, the teacher will share some tips on high-yield peanuts!
When it comes to high yield, the teacher has to say that as long as the flower grows well, high yield is actually very simple, but it is not easy to want to grow well. After all, it is related to disease prevention and fertilization management, no matter which one. If you don't do well, it will lead to a reduction in peanut production. Are you saying that?
Today, the teacher takes a common phenomenon of peanuts. I believe that farmers who have planted peanuts know that when peanuts are ripe and harvested, they will always see a lot of peanuts appearing empty shells, and even some shells are relatively large. But out of stock, do you know why?
Let me tell you, in fact, in addition to the variety differences, the main reason is the soil calcium deficiency, boron, molybdenum, phosphorus and other essential nutrients, such as calcium deficiency, poor pod development, easy to form empty shell, boron deficiency, delayed flowering Wait, what should we do? Please look down!
First, increase the application of organic fertilizer
Organic fertilizers have low nutrient content, but they are comprehensive in nutrition and can fully supplement the nutrients needed for peanuts.
Second, add calcium, increase the application of phosphate fertilizer
When peanuts are deficient in phosphorus, the pods are poorly developed and are prone to empty shells; pods require calcium to enrich the nuts, improve plumpness, poor calcareous pod development, easy to form empty shells, and can supplement calcium phosphate to increase soil calcium and phosphorus content. .
Third, spraying boron fertilizer
Boron is an essential nutrient for the normal development of plant flower organs. The boron deficiency delays the flowering of peanuts, affecting the formation of pods and seed kernels, leading to the empty shell of peanuts. It can be used for 2 to 3 times of root dressing with 0.2%-0.3% borax solution at the initial flowering stage. .
Fourth, spray molybdenum fertilizer
Molybdenum fertilizer can promote the development of peanut root nodules, grow vigorous and full, fruit full and full, can spray 0.3% ~ 0.5% ammonium molybdate solution in the initial flowering stage or the lower needle pod stage.
Five, deep application of potassium fertilizer
Excessive potassium content will affect the absorption of calcium and increase the number of empty pods. Therefore, potassium fertilizer should be applied deep below the result layer. If the peanut seedlings are weak and the leaves are light, it is recommended to spray a high-potassium series of large-scale elemental water-soluble fertilizers, spraying once every 7 days or so, for 2 times, which can reduce the peanut shell rate and increase the seed setting rate.
