I. Isolate planting to prevent stringing
In order to guarantee the grain color and edible quality of fresh corn, it must be isolated from other types of corn when it is planted on the site. The distance between the two types of corn is about 300 meters. If space isolation distance is not enough, time can be used to isolate, that is, through the wrong period of sowing, so that the loosening of the two types of corn staggered period, sowing should be at least a difference of more than 20 days. At the same time, fertility should be selected for cultivation in the fields with good irrigation and drainage.
Second, apply base fertilizer, fine soil preparation
Basal fertilizer is dominated by organic fertilizer. Mushi quality farmyard fertilizer is 1000-1500 kg and phosphate fertilizer is 30-40 kg. Deeply soil preparation, smashing and leveling, starting from a width of 1.3 meters, planting double lines.
Third, timely sowing, reasonable close planting
Spring sowing is planted in March and autumn sowing is planted around August. The spacing is about 50 centimeters, and the spacing is about 32 centimeters. About 3,300 plants are planted per acre. Carefully sowing, to achieve full seedlings, seedlings, Miao Zhuang.
Fourth, scientific fertilization, strengthen management
In the 3-4 leaf stage, the seedlings were transplanted and the seedlings were transplanted. After the transplanting, they were watered. When the leaves were 5 leaves, 1 seedling was planted per hole. Strengthen the seedling management, timely apply Miaofei, promote strong seedlings, maintain balance, combined with top-dressing for the management of the cultivator, loose soil during the seedling stage, the jointing period to the soil before the big bell-mouth period. Rational irrigation and drainage, keep the soil moist, pay attention to prevent flooding at the seedling stage, tasselling silking period to prevent drought, especially flowering pollination period can not be affected by drought.
V. Timely prevention of pests and diseases
We must focus on the prevention and control of underground pests at the seedling stage and corn borers in the middle and later stages. We must pay attention to the prevention and treatment of diseases such as leaf spot and sheath blight in rainy and humid weather.
When sowing, apply 3% Miler granules 5-6 kg mixed fertilizer per acre, or mu using 1 kg 0.3% fipronil or 5% insecticide granules evenly spread in sowing In the trenches, underground pests can be controlled; corn borer can be controlled by 50% Ba Dan wettable powder 100-150 grams mixed with 8-10 kilograms of fine soil made of toxic soil applied to the heart; or pyrethroids insecticide Agent 1000-2000 times liquid perfusion or spray; control sheath blight. Seeds with 0.02% seed soaking or 2% Lingfu Mixture have the best control effect; at the early stage of disease, 10% Shigeo or 20% tricyclazole 1000 times, or 50% dexamethasone 800 times. Spray, spray once every 7-10 days, even spray 2-3 times.
Six, timely harvest
About 23 days after pollination (milk ripening period) is suitable for harvesting period and should be timely marketed.
