I. Variety selection
The overwintering production uses low-temperature and low-light-resistant varieties such as Tianjin Express Garden, Ziyuan Garden and Solanza No.2. The middle and late-maturing varieties were selected for spring and summer production, such as Ziliang 1, Ziguang, and short black.
Second, nursery
1. Sowing period Sunlight greenhouse Winter peony in mid-and late-August, winter and spring pods in mid-and late-December. Spring exposed land from early January to early February.
2. Seedling management (1) Seedlings: 1-2 times before seedling separation, remove weak seedlings, seedlings and hybrid seedlings. (2) Separation of seedlings: When the seedlings have 3 leaves and 1 heart, they are divided into seedlings at a spacing of 10 cm. (3) Temperature management: 25-30°C during the day before excavation, 18-20°C at night, 18-25°C during daytime after excavation, and 17-15°C at night.
3, strong seedlings standard seedling age of 80 days, 7-8 true leaves, dark green leaves, seedling height 20 cm, stem thick 0.6 cm, with buds.
Third, colonization
1. Site preparation combined with 5000 kg of high-quality organic fertilizer per acre, 80-100 kg of cooked cake, 40-50 kg of superphosphate and 10 kg of potassium sulfate.
2. Colonization period Sunlight greenhouse Sunburn from late September to early October, late spring and early spring from late January to early February. 3, the density of open cultivation using large and small rows, large row spacing 70 cm, small row spacing 50 cm. In the greenhouse cultivation, two rows of Daxie were used. The ridge height was 20 cm, the width was 80 cm, and the ridge distance was 40 cm. The walkway was narrow. The narrow row was left with a watering groove of 10 cm. The ditch was covered with a plastic film. Plant 2200-2700 plants per acre.
Fourth, field management
1. Temperature management is planted until the seedlings are mild, during the day, 25-35°C, nighttime, 20-15°C, and the ground temperature is greater than 15°C. Maturation to harvest, 25-32 °C during the day, 17-12 °C at night, and the ground temperature is greater than 14 °C.
2. When the water is slow, seedlings and walnuts in the door are poured with water once, and they are carried out in the sunny morning.
3, fertilizer pouring fruit water, 45% NPK compound fertilizer 15-20 kg / acre, in March can be recovered urea, decomposed manure and other quick-acting fertilizer, 10-15 days 1, urea 10-15 kg / acre. During the fruit period, foliar sprays such as Sun Runnong and Fengshenbao are applied.
4, the plant to adjust the double dry pruning, that is left a door eggplant, two pairs of eggplant, two four-door, two full of fruit, leaving two leaves on the Tianguo fruit stuffy tips, after 7 eggs per plant, Leave 2-3 higher lateral branches on the main stem, one for each branch.
5, Baohuabao fruit early flowering period with 30-50 mg / kg anti-droplet spray.
V. Harvesting
The fruit weight is 0.3-0.5 kilograms, and the white or dark green at the junction of the sepal and the fruit has become increasingly obscure and can be harvested.
VI. Pest Control
1. Verticillium wilt is irrigated with 30% DT for 3-4 times, or treated with 500 times solution of thiophanate methyl oil or 500 times solution of chlorothalonil spray.
2, gray mold with lysozyme 500 times liquid, nongrill 600 times liquid control.
3, red spider, vegetable jaundice with 1.8% Qi Qi prime 1000 times, 70% of Kodak EC 1000 times spray.
4, Whitefly used 10% chlorfluazuron 2000 times, the effect is significant.
