Cultivation Technique of Characteristic Vegetable Tart
1. Variety selection: There are two varieties of leeks, ie, leafhopper and big leafhopper. The city uses fleshy and dense leafhoppers as main varieties. 2. Cutting propagation: The vegetable pods do not bloom, and they are grown on cuttings every year. Protected cultivation is generally cut in mid-September. When breeding, one-year-old thick branches are selected and cut 8-10 cm from the base. Each piece of cuttings should have 3-5 shoots, and the cuttings should be soaked with 50 mg/L ABT rooting powder for 24 hours to facilitate rooting. The cutting bed has a convenient drainage and loose soil. General (mu) applies 2,000 kg of organic fertilizer, cultivating and boring, making it 1 meter wide and 10-15 meters long. Smear noodles with 3-5 cm thick washed sand, and then insert the cuttings into the soil in accordance with the spacing of 20 cm and 12 cm. The depth of the cuttings will generally take up 3/4 of the shoots, so that the buds will not be inserted backwards. Fill the water after cuttings and keep the soil moist for good survival. 3, timely planting: cuttings survived, planted in the shed in due course in early October. Before planting, each composting organic manure (2500-3000 kg), ternary compound fertilizer (30 kilograms), deep-turning millet, made into a 1-1.2-meter-wide flat rake, 25 cm spacing, 15 cm planting spacing The ditch is 6-7 cm deep and planted with water after planting. 4, to strengthen management: after planting, the daytime temperature should generally be maintained at 15-20 °C, at night not less than 10 °C, more than 25 °C to ventilation and cooling. 40-45 days after planting, timely cultivator loose soil should be carried out, and topdressing a fertilizer, generally (mu) 5-8 kg of urea. Irrigation is done with a small amount of ground water to keep the soil moist, prevent flooding, reduce ground temperature, and affect root growth. After the first harvest, fast-release fertilizers are applied every 15-20 days until the last harvest. 5. Harvesting: Harvesting can be harvested in 55-60 days, and the main picking is 10-15 cm. Until the temperature rise in mid-May, it is not conducive to the growth of the leaves when the harvest stops for the next season. When harvesting, in order to promote the germination of more new shoots and increase the yield, 4-6 shoots should be left at the base of shoots and the yield per mu (mu) can reach 2000 kg or more.
