Peanut is one of the most widely used oil economic crops in the world. It has the characteristics of wide adaptability, drought tolerance, and resistance to symbiosis with rhizobia. Peanut production not only can effectively guarantee the safe supply of edible oil in China, but also is a country with strong international competitiveness. Pre-planting management Soil treatment: Before planting, the crop is deep-plowed with pears to a depth of 30-35 cm instead of a simple rotary tiller with a rotary tiller (only 15 cm in depth). Before planting land, apply 10 kg of soil conditioner and 25-50 kg of organic fertilizer from public organisms. Seed treatment: Peanut species are dried on the ground for 1-2 days (not on the concrete floor) before planting, which improves the quality of the germ. Before seeding, seed dressing with Kapok and Kangpu molybdenum increased seedling rate and tidy rate, laying the foundation for high yield. Fertilizer selection When composting with seed fertilizers, fertilizers should be formulated with medium-nitrogen, high-phosphorus and high-potassium formulas, such as Zhongde Peanut Special Fertilizer 13-15-12 (with boron, organic matter) and 16-12-14. 50-75 kilograms per acre; Eutec (12-11-18) compound fertilizer in European agriculture, with 35-50 kilograms per acre, can be seeded and planted in the same crop without burning seedlings; in order to prevent empty shells, use 200-mu per acre. 400 grams of boron. When selecting fertilizers, chlorine-based and sulfur-based fertilizers are selected according to soil conditions. Daily management Seeding requirements: When sowing, the requirement for large peanuts is 5 cm. The average daily ground temperature is stable above 14°C, and the small peanuts are stable above 12°C. The suitable sowing period for spring broadcast in the eastern part of Shandong is from April 25th to May 10th, in Luzhong, Lunan and Luxi areas from April 20th to May 5th. The relative soil moisture content at the time of sowing should be 70%-75%, that is, the soil in the cultivating layer can hold a group and the hand rake is loose. Insufficient sensation, timely cultivation and seeding, in order to protect the seedlings, Miao Zhuang. Seedling management: timely rupture of membranes, release of wind, seedlings and seedlings, after seedlings, 800 times of lion green and 500 times of Kelpke are used to increase the quality of seedlings and promote the growth of leaves and roots. Mid-term management: flowering and podging stage (inferior fruit stalking stage, early wheat harvesting stage), ridge raising, soil watering in combination with soil moisture, combined with control of cotton bollworm and leaf spot, spray Kombo 1500 times and lion blue 1000 times, improve the quality of pollination and fertilization, and increase the fruit setting rate. At this stage, attention should be paid to scientifically controlled cultivars. Stems should not exceed 35 cm. Pre-harvest Management: Full-fruited period should be sprayed 1,000 times in time or 500 times faster than the instant potassium, to reduce the grain phenomenon, increase production, according to soil moisture, timely watering and drainage. Harvest requirements: 3-4 leaves of the main stem remain, more than 70% of the underground fruit pods hardened, clear mesh, when the inner wall of the fruit shell was a green patch can be harvested. Drying immediately after harvest, the moisture content of pods was reduced to less than 8% within one week. When harvesting, it is necessary to pay attention to the recovery of residual film at the same time to achieve a net clean film and prevent the residual film from polluting the soil, environment and forage. It is hoped that the farmers who grow peanuts will use their own actual conditions to select suitable fertilizers, strengthen daily management, and obtain high yields when harvesting.
