Summer corn field
Summer corn is light and heat-resistant, and it can be planted in a wide range of densely planted plants. It can be planted with a variety of crops. In the case of no reduction in corn production, the income per unit of land area is significantly increased. Each 1/15 hectare (1 mu) can increase income by 300. ―1500 yuan.
First, summer corn and peanut summer corn are densely planted, and the peanuts are high and short, which can give full play to the advantage of sideline. Every 1.6 meters wide is a planting belt. In mid-May, 5 rows of peanuts are planted between each planting wheat line, about 10,000 piers per 1/15 hectare. In late May, the corn was interplanted on the wheat ridges, with a row spacing of 1.6 meters, a plant spacing of 13 cm, or a distance of 26 cm from the double plant, with about 3,300 plants per 1/15 hectare.
Second, summer corn and autumn potatoes and potatoes like cold, not resistant to high temperature and glare, and corn with high and low intercropping, can use corn shade to cool down. Corn was planted on the back of wheat ridges in late May, with a line spacing of 1.8 meters and a plant spacing of 10 cm, with about 3,500 plants per 1/15 hectare. After the wheat was harvested, the soil was smashed and planted. Three rows of potatoes were planted in the corn row in early August, with a plant spacing of 25 cm and about 4,500 plants per 1/15 hectare. The potatoes are soaked with gibberellin solution before sowing, and the big buds are sown after sowing.
Third, summer corn and autumn cowpea corn are planted in large sizes. Cowpea can use corn stalk as a scaffold, which saves labor and economy and can greatly increase income. The corn was interplanted in late May, with a small row spacing of 30 cm, a large row spacing of 130 cm, a plant spacing of 25 cm, and 3,300 plants per 1/15 hectare. After the wheat harvest, the soil was cut off in time, and after pouring the water into the corn, the two rows of cowpeas were placed in the corn row at a distance of 25 cm from the corn line in the first half of July. The distance between the two points was 25 cm, 3300 holes per 1/15 hectare, and each hole was 3-4. Grain seeds. When the corn is near maturity, the lower old leaves are removed to facilitate ventilation and light transmission. After the corn is harvested, the two corns in the small row are tied into a "human" frame to increase the wind and lodging resistance.
4. Summer corn and autumn tomatoes Summer corn is planted in wheat ridge back in late May, with a row spacing of 2 meters, a plant spacing of 10 cm, a seedling retention seedling, or a pile spacing of 20 cm to leave two plants, about 3300 plants per 1/15 hectare. After the wheat harvest, the ground is destroyed. Autumn tomato seedlings in mid-June, planted in the corn line between mid-July, line spacing 67 cm, plant spacing 35 cm, about 3000 per 1 / 15 hectares. Strengthen the management of fertilizer and water after planting, use hormone treatment, preserve flowers and preserve fruit.
5. Summer corn and autumn cauliflower corn are 2 meters apart and plant spacing is 10 cm. They are planted in wheat ridge back in late May. Autumn cauliflower grows in late June, and is planted in the corn line in early August. The early maturing varieties are about 3,000 per 1/15 hectare, and the late-maturing varieties are about 2,200. After planting, the management of fertilizer and water was strengthened. During the flowering period, 15 kg of urea was applied per 1/15 hectare, and 20 kg of NPK compound fertilizer was applied for every 1/15 hectare of the ball. In the flower formation period, 0.2% potassium dihydrogen phosphate and 0.1%-0.2% borax aqueous solution can also be sprayed on the foliar surface, which has a good effect on increasing cauliflower yield and improving quality.
