"3 茬 watermelon" + "1 茬 sweet pepper" Three kinds of four harvests a year
Mouthwash arrangements: The first batch of Jingxin Watermelon: planted in mid-January, sold in mid-to-late April, with a yield of 3000-4000 kg per mu, and an income of over 5,000 yuan per mu. The second seedless watermelon was planted at the end of April and harvested in late June. The yield was about 7,000 kg per mu and the income was over 3,000 yuan per mu. The third set of Beijing Xin watermelon sets of sweet pepper: nursery in early June, colonization in July; sweet pepper nursery in June, August watermelon vine grow more than 1 meter when interplanting, acres planted about 1,000. Watermelon harvested at the end of August and early September, with a yield of 4,000 jin per mu, and an income of 1,000-2,000 mus per mu; a sweet pepper yielded 5,000 jin per mu, with a yield of 3000-7000 yuan. Management points: 1. Sanhe watermelon should be grafted and nursed. Prevention of watermelon yellow wilt disease, while improving the resistance of watermelon, conducive to early spring arch shed cultivation, mentioning morning market. 2. Apply base fertilizer to ensure the nutrients needed for normal watermelon growth. Base fertilizer is dominated by organic fertilizers, which can be applied to fully decomposed chicken manure 8-10, and then added with 100 kg of high-quality high-potassium compound fertilizer (such as potassium sulphate in Hubei, AKP high-potassium compound fertilizer in the Netherlands, etc.). 3. Early spring watermelon covered by multiple membrane insulation planting. For the specific operation, see the article “5-7 Membrane Covering Watermelon Morning Marketâ€. 4. Management of watermelon after colonization. 1Temperature management: After the planting, the temperature is generally kept at 28°C-32°C, and the temperature should exceed 35°C for ventilation and cooling. Later, as the outside temperature rises, the small arch shed can be removed in due course. 2 Humidity Management: In general, less watering is required in the early stage. After sitting for a week, watering began to promote melon, not water shortage. The lack of water will affect the expansion of the young melon, and even cause melons. In order to improve the sweetness of watermelons and prevent cracking of melons, it is necessary to control the water to maturity after “setting oneâ€. 3 Pruning and artificial pollination: The whole technique of grafting watermelons generally uses triple vine pruning and leaves 2-3 flowers to set aside. Since watermelon is a dioecious and same-plant crop, pollination and fruit setting are required. 4 Diseases and pests control: The major diseases of watermelon cultivation in large arch shelters are fusarium wilt, anthracnose, and blight, which should be promptly controlled by drugs. Such as wilt disease can be used 50% carbendazim WP 500 times solution root; anthrax can be used 5% chlorothalonil powder 600 times or carbonation 1500 times spray control; Blight can be used to make 100 grams, 100 available, Chlorothalonil spray and other defense. Its insect pests mainly include whitefly, aphids, and leafminers. Can be used Aktai, avermectin, beta cypermethrin control. Sweet pepper should pay attention to the prevention of viral diseases and soil-borne diseases. First, to prevent whitefly, while spraying 20% ​​of the virus A500 times plus ningnanmycin 300 times to prevent virus disease; followed by irrigation with roots to prevent soil-borne diseases, 3-4 days after colonization, with the basal root rot 600 times of rooting, interval 8-9 days, even irrigation three times, can effectively prevent the death of sweet pepper.
