Peanut is one of the important economic crops in Huizhou City. The annual planting amount is close to 500,000 mu. In the rural areas, especially in remote mountain areas, almost every household grows peanuts. Due to the relatively backward cultivation level, the average yield of peanuts is still at a relatively low level. Therefore, on the occasion of peanut planting this spring, the author hopes that the majority of farmers will be able to do the following key technical aspects in the peanut production process, so as to obtain high yield of peanuts. Specific technical points are as follows:
First, rational farming fertilization, lay a good foundation for soil and fertilizer
The choice of land should be made of loose soil, convenient drainage and irrigation, and two years of crop rotation and winter plowing in the winter. High-yield peanuts require deep, living, loose soil structure and the soil structure of Panasonic.
After the deep-rotating crops in the field, the crops were harvested in winter and cultivated 20-23 cm deep and matured. Shallow ploughing in early spring, timely ploughing and squeezing after cultivating, making the ground smooth.
Applying basal fertilizer with one-time fertilization method, Mushi smelting home-cooked fertilizer 1000 kg, peanut-specific compound fertilizer 50 kg or compound fertilizer 75 kg, adding superphosphate 40-50 kg, potassium chloride 10 kg, borax 1 kg to plow Apply evenly under the entire layer.
Second, choose high-product species, give full play to the advantages of improved varieties
High-yielding fields should select medium-mature and large-sized fruit, with thick and orderly stems, vigorous growth, erect lodging resistance, and high yield per plant.
Third, wide lines narrow plant dense planting, cultivate robust seedlings
Planting methods using wide-row narrow-row planting, ie, 1.6 m per ditch, 0.30 m wide, 5 rows per plant, 2 seeds per seedling, row spacing of 0.25 m, spacing of 0.18 m. The sowing density is 1.9-2.3 million seeds per mu.
Fourth, the use of film cultivation, moisture preservation soil loose
The adoption of film-covered cultivation of spring peanuts can not only make the sowing time of peanuts 10-15 days earlier, but also achieve the purpose of heat preservation and moisturizing. The covered land can keep the soil loose during the whole growth period, which is extremely conducive to improving the robustness of peanuts. Rate and fill rate.
After the seeding is completed, before the film is covered, a thin film of water shall be poured and the cover film shall be applied. The film shall be pressed tightly with mud to make it sealed. The surface shall be pressed with a piece of mud in place to prevent the film from being blown by the wind and tearing. crack. When the peanut seedling grows green, it should be manually drilled to help grow seedlings.
V. Control of seedlings and prevention of diseases to ensure stable production and high yield
Peanut high-yield fields use one-time fertilization technology, soil basic fertility is high, and the peanut population is susceptible to premature growth in the early stage, and is prone to premature aging in the later period. Therefore, management measures should be taken to control the disease and ensure the stable production and high yield of peanuts. Mainly grasp the following measures:
40-50 days after the start of peanut control, that is, the early period of peanut scab, when the plant grows to 30 cm, it should be sprayed with 70-100 mg/L PP333 solution in time, and 50-75 l can be used per mu. Peanut plants can be dwarfed to prevent lodging. If the growth is still too strong after spraying, spray once again every 10 days or so to ensure that the plant height is 30-40 cm.
Pest control 15-20 days after the beginning of peanut flowering, according to the condition of leaf spot, spraying 25% carbendazim 500 times solution every 10-15 days, 2-3 times in total, pay attention to prevention and treatment of seedlings. Horses and aphids, flower needles, and scarlet period should pay attention to control of cotton bollworms.
Fertilizers outside the roots can be sprayed with 1% urea solution and 2%-3% of superphosphate 1-2 times after the stage of scarring.
Properly watered peanuts are relatively drought-tolerant crops, and the water requirement for each growth period varies greatly. For example, the water requirement from seeding to emergence is very small, followed by emergence to flowering, followed by flowering to the pod harvesting period. Moisture, and the supply of moisture should be reduced during the period from the end of the harvest to maturity. Drought was encountered at all stages of development, which had an impact on the yield. Drought was most affected during the crusting period.
