When will Yantai plant peanuts with skins?

Peanut planting in Yantai area is generally planted in 5 cm soil layer when the ground temperature is stable at 65438 05℃, that is, under the condition of plastic film cultivation, in early May, it is generally exposed in the middle and late May. At the same time, soil moisture should also be considered. If it is too dry, it is necessary to water the bottom before the cultivated land. It is also necessary to ensure that the base fertilizer is sufficient, and 5000~6000 kilograms of high-quality organic fertilizer, urea 17~20 kilograms, calcium superphosphate 80~ 100 kilograms and potassium sulfate 20~30 kilograms are applied per mu. All organic fertilizer, potassium fertilizer and 2/3 nitrogen and phosphorus fertilizer are combined in the appetite plough layer of cultivated land before winter or early spring, and the rest13 nitrogen and phosphorus fertilizer is wrapped in the ridge when ridging. The ridge spacing is 50cm, and the hole spacing is 13 ~ 17 cm, that is,120,000 ~150,000 holes/hectare, and 2 seeds are sown in each hole. Plastic film mulching: one border and two rows, small row spacing of 40cm, hole spacing of 13 ~ 17 cm, two grains per hole, namely120,000 ~150,000 holes/hectare.

On-site management:

Plastic film mulching cultivation

During the period from mulching with plastic film to emergence, if it is found that the plastic film is damaged or not tightly covered, it should be re-covered with plastic film in time and blocked tightly. When the seedlings break through the film and start to show their true leaves, scrape off the soil on the film and expose the cotyledons on the ground. If a hole is found, replant it immediately with seeds that promote germination. Before flowering, carry out 1 intertillage weeding in the border ditch. From flowering to pod setting, according to the growth potential of flowers, 500 times of Xianke topdressing essence can be sprayed on leaves instead of root topdressing, or 500 times of 0.2% ~ 0.3% potassium dihydrogen phosphate solution can be sprayed for 2 ~ 3 times, or Diguozhuangdiling can be sprayed to increase nutrient transport, promote fruit development and improve peanut yield. During this period, in case of drought, irrigation should be done in time.

Ridge cultivation

Clear the tree and squat down the seedlings: when the seedlings basically emerge. First pull up the weeds around the seedlings, and then pull up the soil to expose the cotyledons to the ground. Be careful not to hurt your roots. After clearing the trees, it will take about half a month to fill the soil and bury the nest.

Intertillage weeding: Intertillage weeding is divided into seedling stage, clumping stage and flowering stage for three times. Master the principle of "shallow, deep and shallow" and pay attention to prevent seedlings from being crushed by soil at seedling stage; Tillage at flowering stage to prevent damage to fruit needles.

Soil cultivation: half a month after flowering, the soil cultivation should not be too thick, and 3cm is appropriate.
