Can peanuts be planted anywhere in Zhenjiang?

As long as it contains sand, it can be planted.

cultivation techniques

sow seeds

Sowing date. In spring, when the ground temperature of 5cm soil layer is stable at 65438 02℃, the pearl bean flower can be planted. From the end of April to the beginning of May, plastic film mulching cultivation can be slightly advanced by 7 ~ 10 days.

Planting density and mode.

Ridge planting: the ridge spacing is 50cm, 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.

Tiantuan management

Ridge cultivation

Clear trees and squat 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.

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.

Continuous cropping method

Land preparation and clearing. The soil preparation must be fine. In autumn, the soil preparation must be 30 cm deep, and the soil should be raked several times to ensure that the soil is loose, breathable, ridged and compacted in autumn. Through the action of low temperature in winter, fungi causing peanut stem rot and root rot in soil are killed, and the occurrence of diseases and pests is reduced.

Fertilization clearance. During peanut continuous cropping, the application amount of organic fertilizer should be increased, and 4,000 ~ 5,000 kg of high-quality farmyard manure should be applied in combination with autumn ploughing. When sowing, phosphorus and potassium fertilizer are mainly used, and diammonium phosphate 15 kg and potassium sulfate 8 kg are applied per mu. In early August, 2% potassium dihydrogen phosphate was used to spray fertilizer on leaves twice, and at the same time, peanut special microbial preparation containing nitrogen-fixing bacteria, phosphorus-solubilizing bacteria and potassium-solubilizing bacteria and appropriate amount of medium and trace elements were used to control diseases.

Variety clearance. Strengthen isolation, and it is strictly forbidden to introduce from the ward. Select disease-resistant and high-yield varieties and replace them in time. Choose sunny weather to dry the seeds for 2-3 days, and then peel the peanuts. First-class seeds with large and full seeds, bright peel color, high fruit fullness, good uniformity, clear net pattern, moderate size, beautiful appearance, germination potential and high germination rate are selected and combined with shelling.

Management level. After emergence, if there is a phenomenon of lack of seedlings and broken strips, it is necessary to accelerate germination and replant. After all the seedlings are planted, clear the trees and squat down the seedlings, and pull out the floating soil at the root of the seedlings by hand to expose two cotyledons. 15 days later, highland barley will return to the soil to fill the nest. Carry out intertillage weeding for three times in seedling stage, clumping stage and flowering stage, and the first intertillage should be shallow to prevent the stem from burying too much soil and affecting the development of lateral branches, as long as the soil is loosened to remove weeds; The second intertillage is in the stage of nodule formation, and this intertillage can be slightly deeper, generally about 6 cm; The third intertillage was in the flowering stage. This kind of intertillage should be taken extra care to avoid damaging the fruit needles. The depth of intertillage is about 5 cm. That is to say, to master the principle of "shallow, deep and shallow", it is appropriate to cultivate the soil 3 cm after flowering 15 days, not too thick. Strengthen pest control and prevent diseases as soon as possible.

Soil preparation and fertilization

After finishing soil preparation and harvesting the previous crop in autumn, clear the stubble, turn over, rake it flat, flatten it in autumn, and make a new ridge. Prepare the plot covered with plastic film for cultivation, and make the border with a bottom width of 75-80 cm, a side height of 5cm and a side width of 65-70 cm, and make ridges with a width of 20-25 cm and a height of 15cm between the borders, so as to borrow soil and sow.

Fertilize. Ridge cultivation in autumn, apply decomposed manure, kang cave soil, retting green manure, etc. 654.38+0.5 million ~ 30,000 kg/ha, furrow and ridge cultivation, sparse application and border tillage. Ridge farming can also save the use of agricultural fertilizers before planting in the same year. When sowing, apply diammonium phosphate 150 ~ 225 kg/ha and potassium sulfate 75 ~ 120 kg/ha as seed fertilizer. In acidic soil, lime and base fertilizer are applied together. For example, the pH value (pH value) is 6.0 ~ 6.5, lime is 450kg/ ha, pH value is 5.5 ~ 6.0, and lime is 675kg/ ha.
