High-yield cultivation of celery, muskmelon, sweet corn, Chinese cabbage

In recent years, some vegetable production cooperatives in Xinghua City have used sheds to grow celery and thick-skinded melons, and then planted Sweet Corn and Chinese cabbage in open fields, which have achieved good economic benefits. The dry celery was planted in late August, transplanted in late September, and harvested in January of the following year; melons were raised in late February, transplanted in mid-March, and marketed from the end of May to early June; sweet corn was raised at the end of May, June Transplanting in the late period, harvested in mid-August; Chinese cabbage was broadcast live in the sweet corn row in early August and harvested in mid-November. Generally, it can produce 5,000-5,500 kilograms of celery per acre, 2000-2,500 kilograms of melon, 900-1,000 kilograms of sweet corn, and 4000-4,500 kilograms of Chinese cabbage, with a net income of 10,000 yuan per mu.

Celery selection of cold-resistant, strong resistance varieties, such as Jinnan real celery, glass crunchy real celery, Western parsley 5 and so on. The seedbeds were cultivated 7 to 10 days in advance, soaked in fresh water for 24 hours, washed and placed in an environment of 8 to 10°C for germination, and 85% of the seeds were sown when exposed to whiteness. Mix the seed with appropriate amount of fine soil and cover it with a sunshade. After sowing, bed soil was kept moist, seedling height was 2 to 3 cm when sparse seedlings, and 7 to 8 seedlings were planted when the seedlings were placed. Before planting, 3,000 kg of high-quality soil-fertilizer and 25 kg of 45% compound fertilizer were applied per acre. Planting spacing 10 cm, spacing 5 cm. After the live tree, the fertilizer was applied every 15 days. Each time, 45% of NPK fertilizer was applied per acre, and 0.2% borax solution was sprayed. The gibberellic acid solution was sprayed 5 to 7 days before harvest to facilitate the elongated and crispy petiole.

Thick-skinned melons use the honey world, Elizabeth and other varieties. Before transplanting, 1500 kg chicken manure per acre, 40 kg phosphorus and potassium fertilizer, after the plough to do a small sorghum, laying drip irrigation pipe, covering the film. In the seedlings when there are 4 to 5 true leaves transplanting, spacing 35 to 40 cm. Planting water to achieve the degree of soil moisture, usually irrigation 2 to 2.5 hours each time, stop irrigation 10 days before harvest. During the vegetative growth period, the suitable temperature is 28～30°C and the nighttime is about 20°C. The flowering pollination period should ensure that the nighttime temperature is above 16°C, and the suitable temperature for melon expansion is 30～35°C. Single vine pruning requires artificial pollination. When the melons are large, the melons are sparse, and 4 melons are left. When the melons grow to half size, they are melons. In order to prevent melon from infecting the ground and infecting pests and diseases, the grass can be planted under vines when the whole plant is introduced.

Sweet corn used varieties with strong resistance to disease and soft sweet musk, such as Xianyujing No.2. Seedling height 10 to 15 cm when transplanted, planting around 3,000 per acre. After the live tree, 75-80 kilograms of livestock manure water is applied per acre, and 20 kg of urea and 45% of compound fertilizer 10-15 kilograms per acre are applied during the bell stage. During the middle and late stages of growth, attention should be paid to preventing and controlling corn borer.

Chinese cabbage is selected from medium-maturing and disease-resistant varieties such as Lubai 8 and others. In early August, 45% of compound fertilizer was applied at 45% per acre. After sowing the soil between sweet corn rows, the soil was closed with butachlor spray, and then the mulching film was used to make a hole and live. Each row was planted with 6 rows. Cotyledons flattening time seedlings, leaving 2 to 3 seedlings per hole, 2200 to 2400 per acre, 8 to 9 seedlings with leaves, 7 to 10 kg of urea per acre. At the beginning of the package, 5-7 kg of urea per mu was used to facilitate the tight packing of the vegetable trees.
