First, timely Dingmiao In the 3-5 leaf stage of maize, it should be selected in the sunny afternoon, so that "four stays and four go", that is, to retain strong seedlings to weak seedlings, leaving pure seedlings to hybrid seedlings, leaving healthy seedlings to disease seedlings, Leave the seedlings to go to the dwarf seedlings to achieve full seedlings, and determine the spacing between the seedlings according to the density and row spacing. Dangerous diseases caused by rough dwarf diseases can be appropriately postponed to 7 leaves Dingmiao, timely removal of weak plants. Second, transplanting seedlings Insufficient seedlings and severe ridges can be transplanted in front of the three-leaf stage. The transplanting time is best to be selected after pouring or in the afternoon after the rain; the lack of seedlings and severe ridges is not recommended for transplanting seedlings. Leave two plants on one or both sides of the lack of seedlings. Third, do a good job of pest control In the seedling stage, seedling blight, rough dwarf disease, Laodelphax striatellus, thrips, two-pointed aphids, cotton bollworm, and weeds are the key points for prevention and control, as well as other diseases and insect pests. 1, Laodelphax striatellus and corn rough dwarf disease. Per acre with 4.5% beta-cypermethrin EC 70-100ml (or 5% AVS micro-emulsion 30-50ml), plus 25% imidacloprid wettable powder 20-30g, mixed with 30-40kg mixed spray, concurrent treatment of the horse, second generation Mythimna separata, cotton bollworm, beet armyworm. 2, two Anethrania. Per acre with 5% A-dimensional microemulsion 30 ~ 50ml or 40% chlorpyrifos EC 80 ~ 100ml watered 50 ~ 60kg spray corn roots. 3, seedling blight. At the beginning of the disease, 50% carbendazim WP 500% or 58% MnZn? metalaxyl wettable powder 150?180g was applied per acre, sprayed once every 5 to 7 days, and sprayed 2-3 times. 4, post-emergence weeding. 30% to defend 5ml + 50% atrazine 90ml, or 40g/L nicosulfuron suspension 100ml, watered 30kg in the corn 3? 5 leaf stage directional spray. Nimosulfuron and other post-emergence herbicides should be sprayed. Organophosphorus pesticides should be banned 7 days before and after application, and they should not be mixed with organic phosphorus and other pesticides to prevent the occurrence of pesticide accidents. Fourth, Shizuo Miao 600 kg per mu production level, without the implementation of seeding plots, in the six-leaf stage will be 10? 12 kg of urea, 15 kg of diammonium, 20? 25 kg of potassium chloride, 2 kg of zinc sulfate, along the side of the seedlings open Ditch deep Shi, 15 to 20 cm from the seedlings, apply about 15 cm deep to root and strong seedlings.
