Using greenhouses to take strawberries, melons, cabbage efficient double crops, the average yield of 1400 kg of strawberry, 2000 kg of melon, cabbage 2500 kg, the efficiency of up to 16,000 yuan per mu. Planting melons and pakchoi after strawberry harvesting can give full play to the winter and spring insulation of plastic greenhouses and the role of shelter from rain in summer and autumn, increase the annual utilization rate of greenhouses, and increase planting efficiency.
Strawberries are selected from the Fengxiang varieties that are suitable for early maturing. The per-mu Ji Shi farmyard manure 2000 kg, 50 kg of calcium magnesium phosphate fertilizer, 50 kg compound fertilizer, soil preparation to do stilts, width 45 cm wide, 25 cm high, 45 cm wide groove. In mid-September, 6 to 7 unfolded leaves were selected, and the roots were thicker than 1 cm. The strong seedlings with well-developed root systems were planted on a cloudy day or on a sunny evening. Each row is planted in two rows with a spacing of 20 cm and a plant spacing of 18-20 cm, 7400-8000 plants per acre. Around October 25, the veil was covered with a black mulch and a drip irrigation hose was placed under the membrane. When the temperature dropped to 15°C in early November, the shed film was sewn in time.
Strawberry fruit development temperature is 18 °C ~ 25 °C, during the day the shelf temperature is maintained at 25 °C ~ 28 °C, kept at 5 °C or more at night, the emergence of high temperature above 30 °C ventilation and cooling. Relative humidity in the shed is maintained at 60% to 70%. Timely removal of old leaves, leaves, diseased leaves, and pods that have been extracted, reducing nutrient consumption. Flowering in the shed to assist in pollination during the flowering period can increase fruit setting rate and reduce malformation. Remove small flowers and small fruits, malformed fruits, and pests and diseases on high branches. During fruit enlargement, heavy fertilizer is applied. Generally, 10 to 15 kg of compound fertilizer is applied per acre. After each fruit is harvested, it can be top-dressed in time, and no chlorine-containing fertilizer can be applied.
