After several years of production practice, it has proved that this variety has strong resistance to weak light, high resistance to wilt disease, smooth Melon strips, and good product traits. Through grafting with black-skinned squash, the yield can reach over 10,000 kilograms, which is highly appreciated by producers and consumers. welcome. In order to increase the yield and increase the benefits, it is necessary to adopt corresponding technologies based on the growing trend in cultivation and management.
Oranges are an important nutritional source for human health and have immense economic value. Citrus orange orange-yellow colour, gratifying Fruit savory, harmonious sourness and sweetness, soft taste, flavor is rich and generous.Citrus is believed to be native to southeast Asia, and cultivation of fruit crops occurred in China at least 4,000 years ago.Citrus is a large genus that includes several major cultivated species, including Citrus sinensis (blood orange), Citrus reticulata (tangerine and mandarin), Citrus limon (lemon), Citrus grandis (pummelo) and Citrus paradisi (grapefruit).citrus fruits and juice are the prime human source of vitamin C, an important component of human nutrition.citrus-unique characteristics have hindered the study of citrus genetics and breeding improvement. Complete genome sequences would provide valuable genetic resources for improving citrus crops.

Nursery period. From late September to early October, seedlings are planted and grafted with black-skinned squash. Premature air temperature is too high, seedlings are difficult to control easy to grow, too late to enter the cold winter does not form a strong root system, low yield before the Spring Festival, but also affect the total output. Cucumber seedlings in early spring are in mid-to-late December, and the colonization period is mid-to-late January (before the beginning of spring). At this time, low-temperature light is weak and protection facilities must be added or geothermal lines must be added.
Temperature and lighting management. The suitable temperature for cucumber growth is 15°C-30°C in the seedling stage and 14°C-28°C in the fruiting period. The ground temperature is 18 °C ~ 26 °C, the minimum is above 12 °C (ground temperature is very important), it is the key to absorb accumulated nutrients, run growth, increase production. Therefore, management must adopt different management according to different stages of growth:
1, autumn and winter. From mid-September to mid-December, it is the management of nursery and post-planting. It is necessary to control the temperature to prevent leggy, and proper scratching to promote root growth is beneficial to wintering.
2, deep winter season. From late December to mid-February, this period is a critical period for the output value of Jaguar. The variety can withstand 8000LUX low light and low temperature around 10°C. If the long-term low light and low temperature will affect the output, the light hours should reach 6 hours. For 8 hours, it is necessary to remove the grasshoppers as soon as possible, as long as the temperature of the interior of the grasshopper shed is slightly lowered and quickly rises, the minimum temperature in the shed is maintained at 10°C to 12°C. To properly ventilate early ventilation vents, when the temperature reached 28 °C ~ 30 °C ventilation, afternoon when the temperature dropped to 24 °C, when the combination of vents, the temperature dropped to 20 °C, when the haystack. In order to increase the light intensity after drafting, it is necessary to timely clean the dust on the film. Watering directly affects the ground temperature. If the soil is short of water, look at the weather forecast. At the same time improve the temperature of the greenhouse when the temperature reaches 33 °C ~ 35 °C ventilation, the temperature should be mentioned the following day 32 °C above ventilation.
3, early spring season. At this time, the ground temperature has rebounded and the fertilizer and water management should be strengthened so as to increase the output and increase the benefits.
Fertilizer management. In the fall and winter season, based on the application of base fertilizer, it is generally not top-dressing. Watering is done in the case of watering the seedlings. After the roots sit, they are watered. Usually, water is poured for 7 days to 10 days. In the deep winter season, according to the growing tendency of chaffy cake or Bean noodles, the vats are fermented in the shed and then flushed with water. The water is poured for 10 days to 15 days. Look at the situation when watering, to see the situation of soil water shortage, but also look at the weather forecast, should be poured in the sunny morning after the cold flow of water. The early spring season lasts from late February to mid-April, which is the key period for production. It is necessary to top-up fertilizer in a timely manner. Every 666.7 square meters will recover 15 kg to 20 kg of diammonium phosphate or ternary compound fertilizer, or 800 kg of decomposed manure. With water flushing, water for 5 days to 7 days. In the late spring season, from the end of April to the end of June, we will pay attention to cooling while strengthening the management of fertilizers and waters, and promote the increase of the yield of the melons.
Pest Control. The overwintering cucumber is less resistant to downy mildew, and the main prevention measures in overwintering cultivation are prevention. The timely spraying will not affect the yield. Timely spraying, no disease 7 days to 10 days to spray a drug prevention, found that when the disease 5 days to 7 days, spray a drug.
