Continuous strong rainfall, lack of sunshine, low temperature, and high soil moisture have adverse effects on peanut growth and flowering, and peanut immunity is reduced, which may easily induce peanut disease. In particular, peanut rot of this year is more serious and may continue to worsen after rainfall. Attention should be paid to prevention and control. Spring sowing film peanuts have entered the middle and late stage of growth, leaf disease is about to enter the onset of the disease, we must pay attention to the prevention as soon as possible. From late June to early July, it is the peak of the second generation of cotton bollworms that harms spring peanuts. It must be treated early in the egg and before the third instar larvae. After the rain, the temperature rose, soil moisture was high, peanuts grew rapidly, water and fertilizer imbalances occurred, and yellow leaves appeared, resulting in decreased photosynthetic efficiency. The above-ground fertility plots are mainly caused by iron deficiency caused by iron deficiency, and some are iron deficiency and zinc deficiency due to lack of zinc. Generally, ferrous sulfate, zinc sulfate and other aqueous solutions can be sprayed and used for prevention and treatment. Soils with low organic matter content in the infertile and low-lying plots are mostly due to yellowing caused by nitrogen deficiency and can be sprayed with 0.5% to 1.0% urea aqueous solution. For sandy lands and clay lands where peanuts are planted, soil permeability is poor. Especially for lands that have just been watered and rained, the soil moisture is too high, seriously affecting the normal growth of peanut roots, and timely cultivating loose soil after rain. Promote root growth while controlling field weeds. After summer wheat sowing peanut is still in the stage of emergence, it is necessary to promptly break the compaction and clearing the seedlings. Rotary ploughing and sowing of plots after the rain fell on the plots, to scratch the cover and put the seedlings, after the emergence of the scorpion with the scorpion 2 to 3 times, can spread the temperature, promote root growth, control weed damage. Be careful not to bury the soil. No-till plots are planted on plots of land, and the wheat straw and wheat bran covered on the rows of peanuts shall be cleared in time to allow the seedlings to soak up the sun as soon as possible. The interplanting of peanuts in the wheat field is a positive stage of seedling growth. It is the main period of branching, flower bud differentiation and root elongation of peanuts. It is necessary to remove the wheat straw and wheat bran covered on the peanut tree in time so that the first pair of lateral branches can fully expose the sunlight to the ground. Irradiation, control the internode elongation of the main stem, promote the growth of the first pair of collaterals and the differentiation of the flower buds, so that the secondary branches grow faster and earlier, and at the same time, the underground pests such as earthworms can be reduced. Spring sowing peanuts in the open season is now at the flowering and needle stage, and it is the best time for the cultivator to cultivate soil after the rain. Flattening peanut plots can be combined with cultivator weeds and rakes with earthworms or rakes without plowshares. Peanut cultivating peanuts can be used to rake the soil, increase the ridge width and result range, shorten the distance from the fruit needle to the soil, and create a loose soil environment for the fruit needles and the development of the pods. It can make peanuts with early results and many results. The results are neat and concentrated. , increase fruit weight, increase production. Spring sowing film peanuts have entered the initial stage of scarring, after the rain easily lead to lodging. Controlling the growth of plants in the ground to prevent peanuts from lodging and promoting more nutrients to the pods can increase the number of fruit and fruit weight per plant, thereby increasing yield. When the plant height of peanut reaches a chemical control index of 35 cm or more, plant growth regulators such as paclobutrazol may be sprayed to prevent lodging.
