During the symbiosis between peanut and wheat, due to the lack of sunlight in the lower layer of peanut, the height of the seedlings is fragile. After the wheat is harvested, it is necessary to carry out cultivating and removing stubble to protect the soil as soon as possible to regulate the water, gas and heat in the soil, increase soil permeability, and promote root development. , Nodule formation and robust seedling growth, is conducive to flowering needles. Herbicides reduce the consumption of water and nutrients in the soil and reduce pests and diseases. The cultivator must do a shallow hoe for grass, squat on the soil and be careful. Every time the cultivator soil surface should be loose and even, loosen the soil around the peanut plant and remove the weeds. If rain falls after the cultivator, it should be cultivated once after the weather turns fine. Generally cultivating 3-4 times. In combination with cultivator cultivation, a large number of fruit needles were incorporated into the soil.
Apply Miaofei early and apply fertilizer as appropriate. After the wheat is harvested, it is necessary to combine cultivating and hoeing, watering, and early harvesting of the seedlings, so as to play the role of flowering seedlings, and lay a foundation for the later growth and development of peanuts. According to the multi-point experiment, topdressing nitrogen fertilizer, phosphate fertilizer, and potash fertilizer can significantly increase production. Generally, the effect of phosphate fertilizer is the best, followed by nitrogen fertilizer, and the use of two or three elements is better. The amount of topdressing fertilizer is 15000-22500 kg/ha of sieving organic fertilizer, 75.0-112.5 kg/ha of urea, and 225-300 kg/ha of superphosphate. The top dressing time is appropriate before the beginning of the flowering period on June 25th. If the topdressing is too late, the effect of raising the seedlings will not be achieved and the peanuts will be easily grown.
The absorption of nutrients at the mid-term of peanut growth reaches a peak, and it should be considered as top-dressing for plant growth. For nitrogen-deficient land, 30-60 kg/ha of topdressing urea, 150-225 kg/ha for phosphate-poisoned land, and 1500 kg/ha for low-potassium soil. Due to excessive rainfall caused by peanut iron deficiency, yellow peanut seedlings, can be sprayed with 0.2% ferrous sulfate solution spraying, spraying once every 7 days, and even spray 3 times.
Drought prevention and drainage, control prosperous. Peanuts are drought-tolerant crops, but flowering and fruit-filling periods are critical periods of moisture and are very sensitive to moisture. With the culling of arable crops, the irrigation and drainage system should be promptly organized to prevent drought and rain. When there is no moisture in the soil after wheat, the water should be timely watered before the first flowering stage after topdressing, and it is advisable to use a small amount of water to pour or gully. If there is no rain for a long period of drought in July-August, irrigation should be done in time to ensure that the flower buds are normally fertile. The water accumulated in the rainy season.
The excessive rainfall or high-yield plots are prone to prolonged lodging. If the height of the high-yielding plot exceeds 40 cm and there is a tendency of prosperous growth, the foliar spray of 50 ml/kg of paclobutrazol should be timely controlled to prevent it from falling.
