1. Selection of scientifically selected varieties Planting peanuts in light or sandy soil with a good ecological environment, flat terrain, loose soil structure, medium fertility, convenient drainage and irrigation, and a depth of 20 to 30 cm in the tillage layer; good ecological environment means that there is no field Or not directly contaminated by industrial "three wastes" and agricultural, urban life, medical waste, and away from highways and other environment to grow peanuts. The high-yield, disease-resistant, and adaptable white sand peanut varieties that are unique to Montenegro and do not contain aflatoxin are used; in the last two years, the new variety Huayu 20 has been introduced. Seed treatment is sun-dried for 3 to 4 hours 5 to 7 days before sowing, and the seeds are sorted after shelling, and the seeds and kernels with pests and diseases are removed. Use full, large-sized peanuts as seeds. The seeds can be sown with a 0.3% seed coating. Before sowing, germination tests should be conducted to determine the amount of seed to be used, or to germination.

2. Soil preparation Before planting, deep plowing should be performed on the soil. The depth should be 25-30 cm. Being too deep or too shallow is not conducive to the growth and development of peanuts. At the same time to achieve two ploughs, ploughing 耙 fine, to reach deep, thick, thin, flat. Basal fertilizer is mainly composed of fully decomposed organic fertilizers, supplemented by chemical fertilizers. Organic fertilizer is applied when ploughing deeply and 1500 kg per acre is applied to avoid burning seedlings. When the soil temperature is stable above 15°C, planting is generally appropriate on May 5-10. 1.8 ~ 20,000 seedlings per mu is appropriate. In line with the principle of suitable land for thin soil and thin land, a row spacing of 45 to 50 cm, plant spacing of 6.7 cm sowing single grains, and 13.3 cm sowing of double grains. The soil moisture at the time of sowing is preferably 70% of the maximum water holding capacity in the field. Each acre of peanut special compound fertilizer 15 kg. Applying in the seeding ditch for seed fertilizer, it is necessary to separate from the seeds to prevent burning seedlings, and to promote early growth and strong seedlings.

3. Control weeds 1 to 3 days after sowing, per acre with 72% isopropyl chloride (Dore) EC 100 to 60 to 65 kg of water spray, spray to the ground can be moist.

4. Field management Qingke seedlings is an important measure to increase production. Liberate the first pair of collaterals, which is appropriate when the plants are freshly littered. The clearing depth is based on the exposure of the two cotyledons to the ground. Clearing the seedlings while removing the seedlings. Moisture management should be conducted according to the characteristics of peanuts at each growth stage. Drought resistance should be paid attention to during the flowering stage, and moisture should be paid attention during the mature period. Top dressing, about 20 days after the peanuts began to flower, seize the ridges and a large number of fruit needles before entering the soil in combination with cultivator soil, spreading 10 kg of urea per acre, which is conducive to lowering the needle and increasing the number of knots per plant. In the late stage of growth, it is combined with pest control, with 0.3% potassium dihydrogen phosphate solution per acre, 0.1% borax liquid spraying foliar surface 1 or 2 times, or with foliar spraying of peanut high yield factors to promote plant growth and robustness. In the field where plants grow vigorously and there is a phenomenon of leggy, it can be sprayed with 1.5% paclobutrazol wettable powder 20-30 kg per kg of water for 25-30 days after initial flowering, which can significantly control the growth of the shoot and increase the stem. Stout, increase the weight of pods, increase production by about 20%.

5. Pest control 1 A reasonable rotation with sorghum and corn, and rotations for 3 to 4 years can effectively control pests and diseases. 2 Use the Jiaduo frequency-vibration insecticidal lamp and trap yellow plate to trap and kill Spodoptera exigua, Spodoptera litura, cotton bollworm, thrips, and ground tiger. Install 1 盏 frequency vibration insecticidal lamp every 60 mus; hang 30 40 40 yellow plates (25 centimeters and 40 centimeters) per acre. 3 Chemical prevention should be based on accurate prediction and prediction, and strictly follow the safety use standards for pesticides. 4 control of peanut leaf spot with 50% carbendazim can be wet powder 1000 times spray; control rust with 15% triadimefon (triadimefon) WP 800 times spray. The control of Spodoptera exigua, Spodoptera litura, cotton bollworm, thrips, etc. was sprayed with 5% chlorfluazuron (rubocatil) EC 2500 times; control 50% of aphid resistance Kang Wet 300 times or 40% dimethoate Emulsion 1000 ~ 1500 times spray; Prevention of red spider with 1.8% avermectin (Insect grams) EC 2500 times or 73% Keduite EC 3000 times spray; Prevention of tigers with 30% trichlorfon EC 10 Grams (first dissolved in a small amount of water) and chopped fresh vegetables or rice bran (5 kg) are mixed and sprinkled in the field before the emergence of adult insects.

6. Timely harvest peanuts 90 to 95 days after flowering for the appropriate period. When most of the shells are hardened, the texture is obvious, and the seeds are full, they can be harvested. Heishan County is generally harvested on September 25-30.

Black Waxy Corn Cut

Black glutinous maize is a special type of maize, whose kernel cuticle deposits melanin to varying degrees, giving it a dark and shiny appearance. The kernels are rich in water-soluble melanin and various essential trace elements, plant protein and various amino acids, with a significantly higher nutritional content than other cereal crops.

The origin of black glutinous maize: coloured glutinous maize is generally white, yellow, red, purple and black, with white, yellow and purple maize being the basic colours. The purple gene of a purple-white cross naturally becomes purple if it "beats" the white gene, and vice versa, so if the two make a tie, we see white and purple maize. Purple can turn into red and black maize, or as we often say, "red is purple and black is purple".
