High-yield cultivation techniques of summer peanut

    First, according to local conditions, select excellent varieties

    According to the trials and demonstrations in recent years, the new varieties of peanuts recommended in Henan include Juhua No.1, Yuanza 9102 , Kainong 8598 , Yuhua 14 and Luhua 14 . These varieties have high yield, early maturity, good disease resistance and strong resistance, which is suitable for large-scale planting in our city.

    Second, apply enough base fertilizer, early application of top dressing

   Summer sowing peanuts require sufficient base fertilizer, which should be based on organic fertilizer and phosphate fertilizer. Wheat is harvested, combined cultivator stubble, acres of organic fertilizer 1000 kg to 1500 kg, 6 kg of pure nitrogen, phosphorus pentoxide 6 kg, 5 kg potassium, low fertility Lot nitrogen can be increased, high fertility Lot Nitrogen fertilizer can be appropriately reduced. It is too late to apply the fertilizer to the field. After emergence, the fertilizer should be applied early to promote the early growth of the seedlings. In the later stage, phosphorus and potassium fertilizers can be supplemented by root dressing to supplement the nutrient needs of peanuts.

    Third, grab the time to sow

    "Spring fights for the day, summer fights for time." Peanuts are mainly summer sowing, and the growth period is short, so we must strive to broadcast early, in order to fight for a longer growth period. Generally require about 10 June sowing appropriate. Dry land should be ploughed after the rain, and strive to achieve Qi Miao, whole seedlings, strong seedlings, and even seedlings.

    Fourth, reasonable close planting

    Summer sowing peanuts have a short growth period and short plants. To make full use of the soil and light energy and to exert the potential for increasing the production of the population, the density must be appropriately increased. The seeding rate is generally about 20% higher than that of spring sowing , the row spacing is 33 cm to 40 cm, the plant spacing is 15 cm to 17 cm, and the seed is 10,000 to 11,000 points per acre , with 2 seeds per hole .

    5. Timely application of herbicides

    Usually three days after sowing per acre with 72% EC 120 g Dole to 150 grams, or 25% oxadiazon EC 100 grams to 150 grams of water, 60 kg to 75 kg, wet the ground topsoil. It can also be used for prevention and control before the seedlings with high-efficiency grass cover, fine grass grass or stable killing before the peanuts 3~4 leaves. It should be noted that no matter what kind of application method is used, it is necessary to use the medicine safely, and to achieve one fine, two uniform, three accurate and four.

A fine: the quality of the cultivation of the field should be fine, so that the surface of the field is flat, the soil is fine, and the soil is covered with no dew.

Diyun: Dispensing should be uniform, spray and sprinkle the herbicide. Sanzhun: The area of ​​the applied field should be accurate, and the dosage should be called ( quantity ) .

Four look: look at the seedlings, see the grass, see the weather, see the soil, flexible control of the application period, the amount of application and application methods. Look at the seedlings, the seedlings are not rooted; do not look at the grass; choose the herbicide variety, the right medicine; see the weather, the temperature is lower, the application rate is in the upper limit of the dosage range; see the soil, the sticky soil is higher, the dry soil Apply after rain or after artificial soil.
