Under the circumstance of increasing agricultural product prices and daily wages, how to reduce production input, reduce labor intensity, rationally use resources, increase farmers' income, and mobilize farmers' enthusiasm for farming is an important factor in stabilizing grain and oil planting area. It is very important to study, reform and promote some farming methods. For everyone summary analysis of cultivation technology of spring peanut intercropping sweet potato, farmers brothers for reference.
First, the cultivation techniques of spring peanut interplanting sweet potato
Site preparation
According to the sowing season of peanuts, the whole garden will be ploughed and leveled, and 25 kg of shell dust or lime powder (soil disinfection, neutralization and acidity, calcium supplementation) and 25 kg of calcium magnesium phosphate fertilizer will be applied. According to (preferably north-south trend, it is beneficial to make full use of the sun) every 100 cm wide furrow, then apply about 1.5 kg of 5% chlorpyrifos granules in the sputum, then level the surface, the ditch depth is about 10-12 cm. In the sputum, two seeding ditches are pulled with a cone or a hoe, and the seeding ditch is about 40 cm apart and 2 to 3 cm deep.
2. Sowing
The peanut seeds of the mixed drug will be pre-screened, and 2 seeds will be planted according to the plexus (hole) from 13 to 14 cm; then the gully cover is used, and the ditch depth is 12-15 cm.
3. High soil
When the needles of peanuts begin to lay down, the clearing high soil should be carried out. According to the experiment, the yield of peanuts is directly proportional to the height of the soil. (Because the high-position needles can enter the soil early, the soil permeability is increased, and the root nodules are promoted. Form), knock the soil in the ditch on the shoulder, and adjust a part of the soil into the sputum to flatten it. The depth of the ditch after the high cultivating soil is 25 to 28 cm.
4. Interplanting sweet potato
(1) Sweet potato preparation: Interplanting is generally carried out 30 to 35 days before peanut harvesting; at this time, the potato seedlings are sufficient, and the strong potato seedlings are cut in the sunny afternoon in 2 to 3 days in advance, and each 100 seedlings are bundled into a erected and placed in a cool place. Hungry seedlings.
(2) Interplanting: Before planting, the potato seedlings are dipped in water or immersed in 500-600 times 70% methyl thiophanate solution for 5 minutes. When interplanting, gently pry the peanuts in the clams, and the two will cooperate with each other. One will carefully dig the holes in the clams with a scorpion cone, and the other will put the potato seedlings, and then the soil will be slightly compacted. The plant spacing is about 22 cm. The seedlings are planted with 3000 seedlings, and the potato seedlings are inserted obliquely. At this point, the peanuts have been needled and pods, and the intercropping should be careful and careful to avoid hurting the peanuts.
(3) Irrigation: At this time, the south is still in the rainy season, and the rainfall is sufficient. If the potato seedlings meet the sunny and hot days, they should be immediately flooded, so that the entire surface is wet and drained immediately after the wetness. Irrigation. After the seedlings are interplanted, the soil should be kept moist, which is beneficial to the survival of peanut pods and sweet potatoes.
5. Peanut harvesting
Since the sweet potato has been put into the sputum, you don't have to hurry to harvest the peanuts and insert the sweet potato as soon as possible. You can wait until the peanuts are fully mature and choose the sunny weather. If the soil is dry, the water should be filled once every 2 to 3 days before harvesting. Soaking is appropriate, so that peanuts are easy to harvest, reduce pods, and also reduce the damage of harvested peanuts to sweet potatoes. After harvesting, the peanuts should be spread in the ditch, so that the sweet potato can be used for the fertilizer.
6. Re-applying the edge fertilizer
After the peanut vines are dried, use the ditch without the sun-dried peanuts to plow the earth to press the dried peanuts, and apply 5% chlorpyrifos granules 1 kg or 5% diazinon granules 0.8 kg (killing underground pests). After the soil is cultivated into sweet potato. On the other side, after the opening, the type and quantity of fertilizer applied should be determined according to the soil fatness. Then the soil is ploughed, and finally the vines (that is, the potato vines stretched to the same side) to promote the sealing, prevent the breeding of the cockroaches, and generally manage well. After 10 to 15 days after fertilization, it was closed.
7. Other fields are the same as those of peanuts and sweet potatoes.
Second, the benefits of peanut intercropping sweet potato
Labor saving
Each acre can save the clearing, ploughing, hoeing and hoeing of the sweet potato before harvesting for about 3.5 working days, and can also eliminate the peanut weeding 2 times a day (due to the use of wide rows and narrow plants for weeding fast) At the same time, it can save about 1.5 working days before sweet potato application nodding fertilizer and before applying fertilizer; deducting peanuts and planting (compared with Pingyi) 0.5 working days, high soil for 1 working day, sweet potato cuttings More than 0.5 working days, saving about 4 working days per mu.
2. Provincial
The price difference of sweet potato seedlings per mu is about 60 yuan (so the intercropping, the supply of sweet potato seedlings is oversupplied), and the cost of saving the fertilizer is about 20 yuan. The total cost of the mu is 80 yuan.
3. Increase production
Peanut adopts this planting method, which can make full use of sunlight, good ventilation and light transmission in the field, improve soil permeability, promote the formation and growth of nodule, and coordinate the development of the group and individual. According to the test, the yield can be increased by 10%-20%. Sweet potato yield can increase yield by 20% to 30% compared with cuttings after peanut harvest.
4. Increase income
Peanut not only increases production, but also increases the fullness. If the sweet potato is used as a commercial potato, it can be harvested half a month earlier than the late potato (that is, the peanut is cut after harvest), and the price is higher.
5. Reduce labor intensity
This method not only saves labor, but more importantly, it can reduce 1 to 2 working days in the summer (double grab season). At the same time, it can be applied earlier or later in the process of re-applying the edge fertilizer, which can be flexibly controlled according to the summer workload. Labor intensity during the hot summer season.
Third, the key links
1. Peanut line spacing If the pitch of peanuts is more than 45 cm, the peanuts are too sloping. After high-cultivation, the fruit needles along the sides will extend into the bottom of the ditch along the edge of the coffin. If it is less than 35 cm, sweet potato intercropping will damage the fruit pods in the middle of the clam and affect the yield. At the same time, the peanuts are not easy to seal, and the ditch is easy to grow grass. Therefore, we should grasp the line spacing, about 40 cm is appropriate.
2. If the high-cultivation soil and time peanuts are not high-cultivation, it will not only affect the yield of peanuts, but also cause the sweet potato to form a potato seedling deep after the application of the fertilizer, which will affect the yield of sweet potato. If the high cultivating soil is too early, it will cover some leaves that have photosynthesis function; if it is too late, the soil transferred into the scorpion will easily cover the vines, which will increase the difficulty of soiling and damage the vines.
3. Interplanting time is mastered in the 30-35 days before peanut harvesting, too early interplanting, sweet potato easy to grow high and covered peanuts, affecting peanut growth, too late interplanting, sweet potato yielding and increasing efficiency, and damage to peanuts .
4. Ensure that the survival rate of interplanted sweet potato should be selected as strong seedlings, moderately hungry seedlings, and keeping the soil moist after plugging is the key.
