Film-mulching cultivation has the functions of drought resistance, soil temperature improvement, and soil structure improvement. Therefore, the mulching of peanut mulching film can be planted not only 10 to 15 days in advance, but also early and strong growth of peanuts, light disease, less pods, high fruit filling rate, good quality, and can achieve early maturing and high yield. This technology is very popular among farmers and the area for promotion is also growing. However, in the practical application of farmer households, the phenomenon of ignoring the seedlings of Qing dynasty is generally prevalent, which has affected the further development of the potential for increased production of mulching peanuts. In this case, we must pay attention. First, the importance of mulching peanut seedlings 1. Qingke seedlings can liberate the first pair of collaterals early, to early early-onset, and further increase the purpose of the production of plastic film peanuts. Peanuts have half-retaining properties, if the seeding is too deep or soil compaction, seed placement, etc. will cause the cotyledon to remain soil, seriously affecting the growth and development of the first pair of branches. It was determined that the number of results on the first and second pairs of side branches of the peanut base accounted for about 80% of the total number of fruit in the whole plant, especially the number of results for the first pair of side branches. If you do not timely clear seedlings, it will cause peanut production. At present, in the seedling management of mulching peanuts, only attention should be paid to filming after the emergence of peanuts, and peanut seedlings should be sorted out, while ignoring seedlings for clear seedlings. Therefore, in order to further improve the production of mulch peanuts, we must pay attention to the seedlings. 2. Qingke seedlings can reduce the mulch peanut seedling disease. The disease at the seedling stage, such as rickets, is the most important disease of mulching peanuts. The cotyledon was exposed by clearing seedlings. After exposure to the ultraviolet rays of the sun, not only can the bacteria be killed, but also the resistance of peanuts can be improved, thereby reducing the occurrence of diseases. 3. Clear seedlings can reduce the damage of seedlings. The locusts that were plunged into the peanut field early in spring are buried in the vicinity of the peanut cotyledons. After the clearing, the cotyledons are exposed, and the sun is tanned and old, which is detrimental to the damage of the locusts and reduces the occurrence of locusts. Virus disease occurs, reducing the degree of morbidity. 4. Clear seedlings can promote root growth. Can promote stem thick, dense, control prosperous. Second, mulching Peanut clear seedlings method 1. Appropriate shallow sowing. Because of the good mulching of mulch peanuts, the depth of sowing can be appropriately reduced to 2 to 3 cm. 2. Time and method of clearing seedlings. Peeling pods of peanut seedlings should be mastered when the basic peanut seedlings, combined with filming, seedlings together. Gently pry the soil around the seedlings. Expose the cotyledons to the soil surface and do not damage or knock off the cotyledons.
