The spring peanut flower needle period is the period from the vegetative growth to the reproductive growth of peanuts. The following three points should be grasped in management.
First, cultivating the soil. Combining cultivating and cultivating peanuts to meet the needle soil, using the hoe to break the topsoil and stacking the fine soil to the roots of the peanuts is beneficial to the peanuts to form effective results. Through the cultivating and cultivating, the soil layer can be loose and well permeable, and it is also beneficial to the needles under the needle, and the fruit set rate per plant is improved, thereby increasing the yield of peanuts. At the same time of cultivating, the weeds mixed in the ridges and peanut seedlings should be completely removed from the roots to reduce the contradiction between weeds and peanuts, and promote the growth of peanut plants and lay a high-yield skeleton.
Second, watering and fertilizing. The flower needle is very sensitive to moisture before it enters the soil. If the soil moisture is poor, or the rain is not enough, it is necessary to irrigate and replenish water in time. The flowering period is a period of vegetative growth to reproductive growth, and it is also a period in which peanuts are more demanding and sensitive to fertilizers. In particular, sand land with poor water retention capacity should be topdressed in time. Combined with watering acres, 20 kg of nitrogen and potassium fertilizers were applied.
Third, disease prevention and treatment of insects. Common pests in production mainly include aphids, cotton bollworms, and red spiders. Aphids can be controlled by spray of imidacloprid, and the second and third generations of cotton bollworms are often transferred to peanut fields for damage. They can be sprayed with insecticides such as lambda-cyhalothrin. High temperature and dry weather can often cause the occurrence of red spiders. It can be controlled by special agents such as 哒螨çµ, or broom sputum. The time of administration should be 6-8 o'clock in the morning or 4-6 o'clock in the afternoon. Stem rot and root rot are common early diseases of peanuts. It is necessary to adhere to the principle of “prevention first†and usually manage carefully to improve the disease resistance of plants. 50% carbendazim WP 800 times solution, or 70% methyl thiophanate WP powder spray prevention, spray once every 7 days, has a better control effect.
