Efficient multiplication of winter melon and Chinese cabbage

<

In recent years, Jiangyan City has used two nets and one membrane (shade net, insect net, and film) to grow wax gourd, Chinese cabbage and celery. It can produce 3500-4000 kg of melon per mu, 4,000-5,000 kg of Chinese cabbage, and 4500-5000 of celery. Kilograms, the annual output value of 15,000 to 18,000 yuan per mu.

Melon selection Beijing bells melon, Beijing very early small melon, Nanjing Xiaoqing melon and other early maturing, high yield and high quality, disease resistance, good commercial small melon varieties, single melon weight 2 to 3 kg. In early February, small sheds were used to raise seedlings in a greenhouse. 6 parts of sterile sand soil and 4 parts of decomposed organic fertilizer were mixed to prepare nutrient soil, and 2 to 3 kg of ternary compound fertilizer per cubic meter of nutrient soil and 50% of carbendazim WP was added to 100 g of water to form an aqueous solution. . Immersion seed germination, sowing, each seed sowing 1 seed, after sowing covered 1.5 to 2 cm of soil. The shelf temperature after sowing is kept at 25-28°C during the day and 15-18°C at night. Appropriate cooling after emergence, greenhouse temperature maintained at 23 ~ 25 °C during the day, kept at 12 ~ 16 °C at night. True leaves grew and sprayed with a mixture of 0.2% potassium dihydrogen phosphate solution and 0.2% urea solution. 7 to 10 days before planting, gradually release air to cool the seedlings. Before the planting, laterally dig 1 meter wide and 0.5 meter deep trenches in a greenhouse. The distance between the two trenches is 2 meters. Each mus of the trenches is rotted with 4000 kg of organic fertilizer, 45% of sulfur-based compound fertilizer, 50 kg, and cooked rapeseed cake or cottonseed cake. kg. When the seedling age is about 30 days at the beginning of March, when there are 3 to 4 leaves of the seedlings, 2 lines of wax gourd are planted in the ditch, each line spacing is 50 cm, and about 850 plants per acre are planted. After planting, cover the film and take a small arch. In the night, small sheds are covered with straw or non-woven fabrics, shade nets, etc. The three vines pruned and the first female flower was removed, and artificial pollination was performed when the second and third female flowers were opened. Each plant was selected to retain 1 to 2 melons, and timely fertilization and watering were carried out after sitting on melons, and carbon dioxide gas fertilizer was added conditionally. In the middle and late April, the first crop was harvested at 1 to 1.5 kilograms. After harvesting, the first melon was cut at the base of the plant at 20 to 50 cm, and the film was deeply ploughed and fertilized with 20 kg of urea and 45% of sulfur-based compound fertilizer per mu. After renewal, each cultivar was left with 3 vines and one or two guashes were selected. The second meal began harvesting in late June.

Chinese cabbage was selected for resistance to disease, heat, moisture, and rapid growth of Xiayang 50, heat resistance 50, Dega 16 and other qualities. After the winter melon pulls out, 3000 kg of organic fertilizer and 50 kg of diammonium phosphate per acre are applied. The soil is swelled and ridged. The width is 70 cm, the width of the groove is 30 cm, and the height of June is 7 months. 45 centimeters, 40 centimeters apart, 2 to 3 seeds per hole, 4000 to 4200 seedlings per acre. Seedlings of 2 leaves 1 seedling period, 6 to 7 leaf stage Dingmiao, timely tillage weeding. After Dingmiao combined with watering 15 kg of urea per acre, the initial ball of urea applied 20 kg per mu. Due to the high temperature during the growing period of the Chinese cabbage and the amount of evaporation, watering takes the ground to see dryness and humidity. Generally, 50 to 60 days after sowing, the leaves are harvested and marketed at 1.5 to 2 kilograms. The best harvest period is at the end of August and early September.

Celery chooses the king of California King, Gaoyoudi, Ventura, Jinnan Real celery for its rapid growth, low temperature resistance, and easy convulsions. In mid-July, we chose to build a seedbed at a high altitude and cover the net. Seed soaking with cold water 8 to 12 hours before sowing, remove and drain and mix with fine fluvo-aquic soil, sow lightly after sowing and water. Before the emergence of the soil to keep moist, seedling emergence, weeding 2 ~ 3 times. When the seedling height is 10 cm, spray 1 to 2 foliar fertilizers to promote the seedlings to grow robustly. After the harvest of summer cabbage, the residual leaf rotten roots were promptly cleaned, and the field with severe disease was sprayed with disinfectant. For each mu, rot 4000 kg of organic fertilizer, 50 kg of diammonium phosphate, 30 kg of potassium sulfate, 30 kg of superphosphate, and 1 to 2 kg of zinc sulfate. Deep plowing is done with 20 cm flat rakes, planting 15 to 20 centimeters apart and 10 to 15 centimeters away from the planting. The planting depth is 3 to 5 centimeters. One day before planting, the seedbed was soaked with water to facilitate seedling raising. The main root was 3 to 5 cm long when lifting. After planting, pour enough water. After the seedlings start to grow, pour a small amount of water, and apply 5 kg of urea or 15 kg of ammonium bicarbonate per acre with water. The leaves of the seedlings began to grow upright, and when the underground roots were in large numbers, fertilization and watering were started to keep the soil moist. The plants were sprayed with 50 mg/kg gibberellic acid at a height of 30 cm and sprayed once every 10 to 15 days. For harvesting, when the plants have 4 to 5 large leaves, 2 to 3 leaves are picked and fertilized and watered on the second day after harvest. Harvested once, at a height of 40 to 50 cm.
