In recent years, the benefits of grain production have declined, and the benefits of planting peanuts have been high and stable. The yield of local high-yield spring peanuts can be as high as 3,000 tons, while the low-yielding fields are only 3-4 jin. According to the practice of high-yield cultivation in recent years, if spring sowing peanuts achieves high yields, we must grasp the following key measures.
1. Select high quality varieties such as Luhua No. 11 and No. 14 for good varieties, disease resistance, concentrated results, moderate growth period, large fruit size, and strong adaptability.
2. Fertilizer soil, ridge planting and selection of high-splendid, fertile wetland fields, a week before sowing Mushi quality composting home miscellaneous fertilizer more than 20 + urea 15 kg + superphosphate 60 kg + potassium sulfate 15 kg (or Plant ash more than 120 kg). After plowing, plowing and smashing, the plant is ridged longitudinally along the ravine, with a ridge spacing of 40 cm and a ridge height of 10-15 cm.
3. Appropriate sowing of mulching spring peanuts can be planted in mid-April to facilitate early planting, early maturing, early harvesting, and early morning markets.
4.Scientific sowing First, seed sowing before seed processing, seed soaking, seed dressing with carbendazim and rhizobium inoculation or soaking with ammonium molybdate; Second, sowing density is one row of ridges, plant spacing is 20 centimeters, and sowing rate is 0.7-0.8 Million points, sowing 2-3 tablets per hole; Third, the depth of sowing watering depth is generally 5 cm, watering after pouring enough water; Fourth, chemical weeding can use 50% acetochlor EC 60-70 ml or 48% The addition of Russell equalization; Fifth, the plastic film can increase the production of peanuts by 20-50%, and can improve the quality. General use of 0.007 mm thick ultra-thin film, completely closed coverage; Six is ​​broken film laying seedlings generally in the top soil of peanuts, after sowing about 6-8 days, with a blade light draw "10" word, so that the seedlings successfully unearthed, broken After the film will be broken in time with soil seal. 5, Qingke seedlings can increase production 15-20%, when the first true leaves of 80% of the plants are unfolded, the soil covered by the base of the first pair of branches of the peanuts is opened with a small shovel to expose the cotyledon section and attention is paid to the time of clearing. Keep cotyledons intact.
6. Oriented Whole Plant Firstly, the seedlings will be planted in different directions in the seedling stage so as to be inclined to the ground surface; the second is to use a 30-35cm diameter circle (iron wire) to press the middle part of the peanuts in each hole at the flowering stage to make the 15cm range. The stems stick to the surface.
7, control the water to adjust the fertilizer in the 6-7 leaf period of 4-6 kilograms of urea urea, after flowering acres of 3-5 grams of urea; in full bloom with vitality, potassium dihydrogen phosphate, molybdenum, calcium, boron and other micro Fertilizers are used for extra-root dressing, concentration is about 0.1%, 50-60 kg of fertilizer liquid is used for mu, and three trenches inside and outside the field are matched to provide timely drought resistance, drainage, and drop.
8.Spray regulators are generally used in flowering period with paclobutrazol 200-300ppm or mu ZFong'an (peanut-specific) 40-50 ml, Vitritol 10 ml, and used in the early flowering and blooming flowering peanuts , Such as water spray, can increase chlorophyll, but also increase production.
9. The disease prevention and control of pests and rats is mainly leaf spot disease and fall disease. It can be controlled by carbendazim or mancozeb in the early flowering stage and full flowering stage; the main insect pests are enemy insecticides such as aphids and cockroaches and phoxim. Control; voles can be used 0.05% enemy poisonous sodium salt and other kill.
