Peanut seedling stage is the stage of vegetative growth, and it is also a period of effective differentiation of effective flower buds. This stage of management aims to cultivate strong seedlings, promote roots early, promote early seedling growth, and promote flower bud differentiation. Make a good foundation for flowering the needle. The main management technical measures are as follows:
First, check the seedlings and make up the seedlings: After the seedlings are out, immediately fill the seedlings to fill the gap, carry out germination and replanting or transplanting seedlings.
Second, clearing the seedlings: the yield of peanuts is mainly formed by the pods on the first and second pairs of side branches. The first pair of side branches begin to grow 3 to 5 days after emergence of the peanuts. After emergence, the soil around the plants should be opened in time to expose the cotyledons and leaf buds to the ground, promoting lateral branch growth and flower bud differentiation. At the same time, the herbicide grass is also removed to reduce the damage of the mites, thereby reducing the occurrence of diseases. The depth of the clearing tree is based on the exposure of two cotyledons. Do not damage or knock off the cotyledons when clearing the tree, so as not to affect the development of the first pair of lateral branches. Combine clearing the tree to fix the seedlings.
Third, weeding and weeding: After the wheat harvest, it is necessary to carry out cultivating cockroaches and weeding in the early stage to regulate the water, gas and heat in the soil, and promote root development and nodule formation. The soil inside the ridge is placed between the ridges to control the lower needle of the early flower. Chemical weeding can be used with Putianle 33g or single and double weeding 29g to 40kg of water, evenly sprayed. Spraying must be accurate and uniform to prevent heavy spray and leakage, so as to avoid phytotoxicity in crops.
4. Watering and topdressing: After the intercropping of peanuts, the seedlings should be applied in time to promote the early growth of the seedlings, and the peanut formula fertilizer can be applied 20 to 25 kg or urea 7.5 to 10 kg, and superphosphate 40 kg. It is better to apply it by ditching. If you have a good feeling, you don't need to water it. If you don't have rain after 5 days of sputum, you should water it in time.
V. Anti-disease and pest control: 50% carbendazim 1000 times liquid is sprayed in time to prevent root rot and stem rot in seedling stage; when aphid and thrips are seriously harmful, 40% omethoate 1000 times liquid can be sprayed or 10% imidacloprid 1000 ~ 1500 times liquid control. Earthworms, tigers, and golden worms can be smouldering with phoxim and phytotoxicity in the evening.
