Autumn pepper and glutinous corn, lettuce multiple cropping pattern

The development of autumn and waxy corn and lettuce in Binyao City, Jiangsu Province, has been explored in production practice in recent years. This model produces 2000 kg of chilli per 667 square meters of produce and 1200 kg of fresh spring corn cob. Lettuce 1500 kg, the output value of 13,000 yuan, net income of 9,000 yuan. Autumn peppers are generally planted in the middle and early August. In early September, ridges are planted in wide and narrow rows. The rows are 50 centimeters wide, 30 centimeters in narrow rows, 25 to 30 centimeters in plant spacing, and 4,000 in 667 square meters. They are listed on the New Year's Day to the Spring Festival. Waxy corn is planted at the end of February and transplanted in late March. Fresh ears are harvested in mid-June. In late May, lettuce is sown and planted at the end of June. Planted at the end of June, the plant spacing is 25 centimeters and 33 centimeters, and 8,000 plants per 667 square meters. About the strain, harvested in mid-August. Usually 7 meters wide, plus a ditch, steel frame spans 6 meters, the central walkway is about 40 cm wide.

1. Autumn pepper breeding strong seedlings choose early and mid-maturity, strong resistance, high yield, good varieties of goods, such as Tianjiao No. 2, No. 5, No. 2, No. 4 Jiangcao, No. 4 Luojiao, No. 1 No. 13, Xiangyan No. 13 and so on, planting 667 square meters of pepper need seedlings 6 to 8 square meters. About 15 days before sowing, 1 kg of compost chicken manure was applied per square meter of seedbed, and 50 g of 45% ternary compound fertilizer was used. Turned into a 1.0-1.2-m wide sorghum flour surface, and used for every 667 m2 of field. 150 grams. Before the advent of the seedbed per square meter, 95% of dexamethasone WP 5g or 50% carbendazim 10 15 15g was added. Mix 2 kg of fine soil and mix well and put it into the bed and scoop it again. Before sowing, the bottom water shall be poured, and then the seeds shall be evenly spread on the seedbed, and the soil thickness shall be 0.8 to 1 cm. After sowing, the seedbed should be covered with wet straw moisture. The nursery shed must be covered with a shade net to prevent exposure and rainstorms. Two-leaf one-time Dingmiao, 8 cm square is appropriate. 15 days before planting, 1500 kg of dry chicken manure, 667 kg of ternary compound fertilizer, and 10 kg of potassium dihydrogen phosphate were applied per 667 m2 of land. The ridge is perpendicular to the shed walkway. The ridge width is 50 centimeters, and the ridge width is 30 centimeters. The ridges are planted in two rows. The row spacing is 30 centimeters along the ridge and the plant spacing is 25 to 30 centimeters. The mulch is laid on the ridge to replant the mulch. , 1 per hole. Planted before the field spray 1 fungicide and pesticides, can be used to kill 1500 times 2.5% enemy liquid and 75% chlorothalonil wettable powder 600 times mixed spray. In the temperature management, when the daytime temperature is stable at 25 ~ 28 °C, the outside shading net can be removed. In mid-October, when the night temperature drops below 15°C, it is necessary to close the film during the night and cool down during the day to reduce the humidity and humidity. Before the arrival of the cold spell in mid-November in November, a small arch shed should be built in time to cover the two membranes. In late November, when the night temperature falls below 5°C, cover straw insulation should be stamped. After December, when the minimum temperature drops below 0°C, a layer of film is kept outside the straw to keep it warm. The greenhouse membrane must be compacted with soil to prevent air leakage. The planting and easing seedlings were poured 1 time with diluted manure water, and the result period was about every 15 days. Combined with watering, 5 to 7.5 kg of topdressing urea was applied per 667 m2. In the middle and later stages of fruiting in December, water is generally not supplied as the temperature drops. The following axillary buds were removed from the peppers. For the weaker plants, the first and second buds should also be removed in time to promote plant growth. After the fall, the chili pepper generally maintains 16 or so fruits per plant. After the first frost, the young shoots, ineffective shoots, and buds should be removed to reduce the nutrient consumption and promote the growth of the hanging fruit. After autumn, the common pests and diseases of pepper are maggots, virus diseases, epidemics, and gray mold. Low-toxic pesticides should be used to prevent and treat the disease.

(2) Waxy corn cultivation Seedlings of strong growth, good resistance and good taste are selected, such as Zhongjing No.1, Suyujing No.1, Zheyuyu No.1 and Q Xiangjing No.1. Choose loose soil and fertile plots as seedbeds. Apply 50 g of calcium phosphate, 25 g of potassium chloride, and 5 kg of diluted manure per square meter of seedbed, and pour in soil and mix well until 10 days before sowing. One seed was sowed per seedling, and after sowing, the film was covered with a plastic film, a small arched greenhouse film, and a greenhouse film. In mid-March, 667 square meters of manure and chicken manure 1000 kg, 45% ternary compound fertilizer 30 to 40 kg, evenly in the greenhouse to do fine. Transplanting spacing 65 cm, spacing 25 cm, mulching cultivation, 10 rows per shed, planting about 4100 per 667 square meters. Planting live water when planting, insulation promote long. Shed period temperature management, during the day 25 ~ 28 °C, about 15 °C at night. In early May, the greenhouse film was removed to increase light and promote sound growth. 8 to 9 leaf stage strong stalk manure, 667 square meters of urea 8 ~ 12 kg, potassium chloride 14 ~ 16 kg, and the cultivator soil and appropriate irrigation, promote aerial root growth. In the big bell-mouth period (about 12 leaves), a panicle fertilizer was applied, and 667 square meters of urea was applied to 14 to 16 kg. When waxy corn is used to draw tassels, 25 kg of corn sorghum and 50 kg of water are used for every 667 square meters.
