Rotation of crops for planting can produce high-yield peanut oysters and fear of heavy pods. Heavy peanuts generally show small trees, yellow leaves, early leaves, many pests, and small and small fruits. Some peanut farms with a yield of 500 kilograms per mu are obtained on fertile land that has been planted for five or six years or have not been grown with legumes. It is difficult to achieve the expected yield even if the fertilizer is grown in the heavily planted ground. Practice has proved that crop rotation is one of the measures to effectively increase peanut production. Deep plowing can increase yield and quality. Peanuts are deep-rooted crops. Properly deepening the tillage layer can promote the development of root groups of peanuts and enhance their ability to absorb fertilizer and water, which will help improve the yield and quality of peanuts. Generally deep plowing 26 to 33 centimeters can produce 20% more than shallow plowing 10 to 13 centimeters. Summer sowing peanuts are interplanted and sown two after sowing. The former should conduct deep plowing and fertilization before the planting of the former crop, and at the same time strengthen the middle cultivator in the later stage of the previous crop to create loose and lax soil conditions for interplanting peanuts. The latter should promptly exterminate the crops after they are harvested, and pay close attention to fertilization, cultivating and sowing. The use of QF fertilizer as a basis for adequate application of basic fertilizer has resulted in early differentiation of peanut flower buds, long-term vegetative growth and reproductive growth, and a weak initial nitrogen-fixing ability of rhizobia. Fertilizers are difficult to apply when the fruit needles are plunged in the middle and later stages. Therefore, the application of basal fertilizer is very important, and the amount of basal fertilizer should account for 80% to 90% of the total amount of fertilizer. Some peanut farms only use basal fertilizer, and they can also obtain high yields without topdressing at a later stage. Basal fertilizer is mainly organic fertilizer. Organic fertilizer can meet the needs of peanuts for various mineral elements and improve soil. Per acre Shi 500 ~ 2000 kg of quality circle fertilizer, peanut production is 150 ~ 200 kg; per acre Shi 2500 ~ 3000 kg of quality circle fertilizer, peanut production is 250 ~ 300 kg. The poorer the fertility, the more obvious the effect of organic fertilizer, the new whole farmland must apply more organic fertilizer in order to ensure the high yield of the year. The application of phosphate fertilizer to peanuts requires more phosphorus than normal crops, and it also has high absorption and utilization of phosphate fertilizers. Practice has proved that after applying phosphate fertilizer to peanuts, it not only has an effect on the increase of peanuts planted in the same year, but also has obvious aftereffects. Applying 10 kg of calcium phosphate per acre results in a 18.2% increase in peanut production in the year, and a 30% increase in corn production in the second year. The effect of phosphate fertilizer can be maintained for more than 3 years. Phosphorus fertilizer has a significant effect on the growth of peanuts, but the size of its increase in yield and fertilization techniques are closely related. The less organic fertilizer, the higher the effect of phosphate fertilizer. When the amount of organic fertilizer is 2000 kg, the effect of phosphate fertilizer is not obvious. In addition, the phosphate fertilizer is easily fixed by the soil. Therefore, the phosphate fertilizer and the organic fertilizer are mixed and piled up for more than half a month, and then finely pulverized, and the concentrated furrow application at the time of sowing is more effective. In the thin application of phosphate fertilizer, adding 2.5 to 5 kg of nitrogen fertilizer per acre as a seed fertilizer can better exert the effect of increasing phosphorus production. However, attention should be paid to the application of seed fertilizers to isolate the fertilizers and seeds so as not to harm the seeds and affect their germination and emergence. Calcium Fertilizer Peanut application of calcium fertilizer can regulate the pH value of the soil, increase the nitrogen-fixing ability of Rhizobium, improve nitrogen nutrition, promote the development of pods, reduce empty fruit and rotten fruit. Calcium-deficient peanuts have significant effect on increasing yield after applying calcium fertilizer. Artificial inoculation of peanut fungus with rhizobia can make peanuts root nodule and multiple nodules as early as possible, and improve the nitrogen fixation ability of peanut plants. At present, Peanut Rhizobium, or Rhizobium, is widely used in production. It uses 25 grams per acre. When it is used, it should be mixed with appropriate amount of water to form a paste and mix the seeds. , Also avoid mixing or contacting with bactericides.
