Water is required to be supplemented and irrigated in a key summer corn growth period, namely a large-horn mouth period, and the water is irrigated by about 30-40 cubic meters per mu each time.
3) Cultivating: in summer, the corn field is generally intertillage twice, hoed once when seedlings are set, hoed once when 10 leaves are spread, and hoed manually or mechanically. The field block which is sealed after the corn is sown by the herbicide can be intertillated and loosened by one time when 10 leaves are spread after the joints are pulled out.
4) Fertilizing:
base fertilizer: 300kg of commercial organic fertilizer is applied per mu at one time during sowing, and 10kg of special long-acting controlled release fertilizer for corn is applied at one side of a sowing ditch as a base fertilizer. The fertilization depth is generally below 5cm, the seeds and the fertilizer are separately fertilized and cannot be too close to the seeds, and the seedling burning phenomenon caused by the contact of the seeds and the fertilizer is prevented; topdressing: 10kg of urea is applied to the rhizosphere during the period from 10 leaves to a large flare.
5) Weeding: after corn is sowed and before seedlings are planted, 1500-2000 times of solution containing 72% of metolachlor and 10% of mesotrione is uniformly sprayed on the ground surface per mu, or after the corn seedlings emerge, 100ml of 10% mesotrione suspending agent is added with 30-40 kg of water for uniform spraying.
6) Preventing and controlling lodging: the cultivation method is characterized in that manual or mechanical ridging is combined with intertillage, lodging is prevented, or an artificial growth regulator is sprayed to strengthen stalks and prevent collapse, and chemical control agents such as rooting powder, corn robustin and the like are generally used for seed treatment or sprayed before jointing.
(4) And (3) pest control:
1) corn leaf spot disease: in the initial stage, the 70% thiophanate-methyl wettable powder 1000 times liquid and the 70% mancozeb wettable powder 1000 times liquid are used for preventing and treating for 1 time and 1-2 times every 10 days.
2) Aphids: in the pest period, 2-3 g/mu of 70% imidacloprid water dispersible granules are added with 40-50 kg of water for uniform spraying control per mu.
3) Corn borer: in the large-horn mouth period of corn, 20ml of 4.5 percent beta-cypermethrin emulsifiable concentrate is mixed with 40-50 kg of water for even spraying per mu to prevent and control the corn borers.
(5) Harvesting in due time:
when the bracts of the summer corn are whitened and the upper opening is loosened, the black layer at the base of the seeds appears, and the milk cords disappear, the summer corn can be harvested. Early harvest (immature) is detrimental to both corn yield and quality. If the next crop needs to be harvested in the morning for making up the land, the stalks can be harvested continuously, and the fruit ears can be broken off after 1-2 weeks.
