First, check seedlings make up seedlings to prevent seedlings off the ridge in order to ensure the whole seedlings, seedlings should be timely check seedlings, with early maturing varieties of germination after replanting or in the seedlings before 4 to 5 leaf age, in the afternoon or cloudy day with soil transplant seedlings. Maize 3 to 4 leaves when and time seedlings, 5 to 6 leaves Dingmiao, pull out weak seedlings, seedlings, diseased seedlings, round stalk seedlings, choose to stay the same size of Jianmiao.
Second, seedlings, Dingmiao three-leaf stage and time seedlings, the five-leaf period in time Dingmiao, between, Dingmiao, to weak seedlings, seedlings, diseased seedlings, miscellaneous seedlings, leaves the growing strong seedlings, the lack of seedlings 1 to 2 strains Place to stay close to two plants.
Third, Shi Miao Fei timely protection of irrigation, according to the soil moisture, do see the sky (that is, rainfall)
Look at the ground (according to the soil moisture in the field) and see the seedlings (wilting condition of the noon leaves) timely irrigation; for the fields that do not use seed fertilizer, Mushi compound fertilizer 15 to 20 kg, or Mushi urea 4 to 6 kg, diammonium 4 to 6 kg, potassium chloride 8 to 10 kg. The large bell mouth Mu recovery urea 15 to 20 kg.
IV. Prevention and control of underground pests After corn emerges, bait can be used to control cockroaches, golden needles, cockroaches and small tigers. Using 10 kg of fried wheat bran or bean cake, add 50% of 50% phoxim EC and 3% of methylisothiphos granules 2 to 3 kg to make poison baits. In the evening, bait baits in the corn row. 2 kg per mu, control effect is very good.
Fifth, chemical weeding chemical Weeding must strictly select the type of herbicide, accurately control the dosage. Corn seedlings can be used before the seedlings of 40% epinephrine or 40% isopropylate suspoemulsion 150 ~ 200 ml / acre, can also be used acetochlor 100 ml / acre, watered 30 to 40 kg, evenly spraying the ground; Corn can be treated with stem and leaf after 5% yulon suspoemulsion 75~100ml watered 30kg before corn emergence; maize can be used between 2nd line directional spray when the weeds are bigger after 5 leaves stage. Grams of traces of water 120 ~ 150 ml, watered 30 ~ 50 kg for uniform spraying between the corn lines, be careful not to spray on the corn. When herbicides are used, the amount of water should be increased appropriately. The soil must be kept moist and high temperature weather should be avoided so that no heavy spray or leakage can be achieved.
Second, seedlings, Dingmiao three-leaf stage and time seedlings, the five-leaf period in time Dingmiao, between, Dingmiao, to weak seedlings, seedlings, diseased seedlings, miscellaneous seedlings, leaves the growing strong seedlings, the lack of seedlings 1 to 2 strains Place to stay close to two plants.
