In the spring season, the yield of the quails was higher in the anti-season cultivation. The Bayi team in Hengxi Village, Henglan Town, Zhongshan City had a long history and rich experience in planting anti-season festivals. The three-dimensional planting model was used to grow the quails and vegetables as early as possible. Each melon produces up to 3000 kg or more, and the use of open cultivation, both the provincial labor, economic benefits and good.
I. Variety selection and germination sowing The spring varieties of the zucchini varieties include Guanxing No.2 zucchini, Guanhua zucchini, and Jiangxin No.4 zucchini. Since the seeds of the zucchini are not neatly sprouted, the germination work should be done regardless of direct seeding or nursery. The specific method is: soak the seed in warm water of about 50°C for 4-6 hours, dry it and place it under a constant temperature of about 30°C. When most seeds germinate 0.5-1.0 cm long, it will be fine. sowing. Since the quince is a thermophilic vegetable, higher temperature is required and the optimal temperature for growth is 18-30°C. In order to ensure the normal growth of the zucchini, the sowing date of the spring planting cultivation is selected before and after the “Xiaohan†and the plastic film is used to cover the germination. The temperature of the seedling stage must be adjusted to ensure that the whole seedlings are raised and the seedlings are raised.
Second, site-planting, Shizu zygosity is easy to be affected by melon soil diseases, avoid continuous cropping. Hyacinth but not resistant to pods, the whole growth period requires more fertilizer, so it should be planted on sandy loam fields with deep soil, convenient drainage and irrigation, and fertile soil. The method of site preparation is: 15 meters long and 2.5 meters wide. The field will be erected and turned into a base. The base is a water channel. The depth of the channel is 1 meter. The four canal fishes can be stocked in the canal and it is convenient for irrigation. Two rows of plants were used with a spacing of 1.2 meters and a spacing of 0.4 meters. Each field was planted with about 250 plants. After the hyacinth breeding, it began to set up the field and apply sufficient basal fertilizer, and applied 800-1000 kilograms of rotten earth fertilizer per acre, 25-30 kilograms of superphosphate and 25-30 kilograms of peanut bran. Generally around the Spring Festival, the guava seedlings with 3-5 true leaves, when the temperature is stable at about 20 °C can be transplanted, planting medlar, medlar height 20 cm, covering a small amount of straw, watering enough rooting water.
Third, field management
1. Stretching and arranging vines, pruning and squashing. The melon seedlings grow to 12-15 leaves in length. When the vine grows 0.8-1 meters long, the bamboos are used to guide the vines. The word “human†is used to introduce vines. Straighten along the direction of the support, and put new roots on the earth. Zucumber dominated by the main vine. The side vines were removed in time before the main vine. After the main vines, the side vines above the middle were selected to increase the number of side vines and increase the total yield.
2, reasonable top dressing in accordance with the "pre-thin, moderately heavy, moderate after" principle, the early spring season low temperature guava, seedlings should control the fertilizer, inhibit growth to improve cold hardiness. Avoid partial nitrogen fertilizer so as not to grow long. After the planting of thinning plants, a top-dressing fertilizer shall be applied in a timely manner. Each per acre will be applied with 1000 kg of 10% fecal urine or 1,000 kg of a compound fertilizer with 4-6 kg of leachate. Before the introduction of vines and flowering results to be re-fertilized, 30-40 kg of compound fertilizer per acre, 2-3 times after picking melon fertilizer once, 20-30 kg of compound fertilizer per acre and 5 kg of potassium.
3, moisture management, fruit and vegetables, avoid taboo melon, especially in the flowering period of the result of a larger amount of water, should be timely irrigation and keep the soil moist. After the spring festival, the lotus seedlings are usually sprayed once a day at sunny noon. After flowering, the water is poured on sunny afternoons. Water should be stopped 3-4 days before harvesting. After the rain, pay attention to drainage in time to prevent water accumulation.
IV. Pest Control
1. Disease prevention and control damping-off disease can be sprayed with 75% chlorothalonil 800 times solution or 70% dexamethasone 500 times; powdery mildew can be sprayed with 20% triadimefon 2000 times solution or 10% epoxide 2000 times solution; 64% anti-virus 500-800 times, 58% 500-700 times, or 800 times Locron used; downy mildew available 75% chlorothalonil 800 times or thiophanate-methyl 800 times Spraying.
2. Pest control Hummer can be used 40% Qixingbao EC 600-800 times, good year of winter EC 1000-2000 times or 10% Imidacloprid WP 2000-4000 times; Guatya 48% available The 1000 times liquid or 90% trichlorfon 1000 times sprayed; quail with 50% killing pine 1000 times or spraying Bacillus thuringiensis preparations; fleas available 73% Kede 2000 times or 20% dicofol 1500 times liquid spray.
