The emergence of peanuts from the emergence to the beginning of flowering seedling period, the length of the seedling period, generally takes about a month. Peanut seedling stage is the main stage of vegetative growth, and it is also a period of effective flower bud differentiation. The characteristics of fertility in this period are the slow growth of the above ground part, the rapid root extension, and the nutrients produced by the plant mainly for the development of roots and the formation of flower buds. In this period, due to the relatively small number of nutrients, too much fertilizer and water, it will cause stems and leaves to grow long, affecting the development of roots and the formation of flower buds. Therefore, the central task of the seedling management is to appropriately control the growth of the aboveground parts on the basis of guaranteeing Miaoquan Miao Qi, so as to make it strong and not prosperous, and to achieve strong seedlings, thick stems, numerous branches, dense sections, and well-developed root systems. The formation of a large number of flower buds lays a good foundation for flowering needles. Its main management technical measures are as follows:
First, check the seedlings make up the seedlings: After the seedlings are out, immediately check the seedlings to make up for deficiencies, and regenerate seedlings or transplant seedlings.
Second, Qing Ding Dingmiao: The output of peanut is mainly formed by the first and second pair of side branches. The first pair of lateral branches began to grow 3 to 5 days after the emergence of peanuts. After emergence, the soil surrounding the plants should be opened in time to expose the cotyledons and lateral buds of the leaves to the ground to promote lateral branch growth and flower bud differentiation. At the same time, it also removes phytoplankton and reduces locust infestation, which also reduces disease occurrence. The depth of clearing trees is based on exposing two cotyledons. Do not damage or knock off the cotyledon when clearing, so as not to affect the development of the first pair of lateral branches. Combine with clear trees for Dingmiao.
Third, weeding and weeding: After wheat harvest, we should carry out early cultivator eradication and sorghum grasshoppers in order to regulate the water, gas and heat conditions in the soil and promote root development and nodule formation. Put the soil in the ridge toward the ridge to control the lower needle of the early flower. Chemical weeding can be used to mix and match 40 kg of water and spray evenly. When spraying, it must be accurate and uniform to prevent re-spraying and missing spray so as to avoid crop damage.
Fourth, watering topdressing: interplanting peanuts after the harvest should be timely to raise the seedlings to raise seedlings, to promote early-onset strong seedlings, acres can be used to formulate peanut fertilizer 20 to 25 kg or urea 7.5 to 10 kg, 40 kg of superphosphate. It is better to apply the ditch. If you have a good sensation, you don't need to water it. If you don't have rain, you must water it in 5 days.
V. Disease prevention and pest management: Spray 50% carbendazim 1000 times later to control root rot and stalk rot in seedling stage. When the locust and thrips are seriously damaged, spraying 40% omethoate 1000 times or 10% imidacloprid 1000 to 1500 times liquid prevention. Earthworms, ground tigers, and golden worms can use phoxim and earthworm-killing baits to spread around peanuts in the evening for prevention and treatment.
