Round No.1 is a special early-ripening melon cultivar. From the 5th to the 6th leaves, the side vines begin to have female flowers. After 10 to 13 days after flowering and pollination, the tender guarana can be picked and marketed. About 15 days earlier. Melon is oblate and plump, and the melon is tender green. The meat is white and tender, with few fibers, soft and juicy, and pure and fresh. This species has strong adaptability. It can be planted both in the south and in the north. It is not only suitable for greenhouse cultivation in early spring, but also suitable for open cultivation in spring and autumn. It can be planted in different seasons according to market needs. 1. Sowing and seedling cultivation: The method of seeding and raising seedlings of Yuanjing No. 1 is similar to that of cucumber. The seedlings are seeded with nutrient mash or seedlings, and sowed after germination. Sowing time can be arranged from 2 to 8 months, and 2 to 3 true leaves are planted. 2. Planting: After harvesting the former crop, plowing shall be performed in time. Apply enough basal fertilizer to apply 3,000 kg of fertilizer and 100 kg of compound fertilizer per acre. Use applicator, then open ditch for smashing and leveling. Ditch should be unobstructed, can not be stained with water. Because the melons have large leaves and grow vigorously, they require a large row spacing. Generally, they are planted with 1.8 meters of furrows, each row of two rows of 40 to 50 centimeters. It is grown on an adult frame and stands about 2 meters high. 3. Fertilizer and Water Management: Pour a little faecal water immediately after planting. Fertilizer 3 to 5 times before flowering, with diluted human and animal waste as well. When you start flowering, you have to stop the supply of fertilizer and water to facilitate sitting on melons. When the first batch of melons has an egg size, the fertilizer and water supply should be strengthened, and a batch of melon leaching water should be collected once. In high temperature and drought, furrow irrigation or water drought. Large cultivation should increase the amount of ventilation and ventilation during the period of squashing, reduce the humidity in the shed, and prevent steep growth. If there is excessive vegetative growth, one should strengthen pruning, and the second is to spray paclobutrazol 1 or 2 times. 4. Whole cultivars: The female flowers of the main vine of the pod melon are late, and the vines of the vine 1 to 2 have almost all the female flowers. In order to promote the early occurrence and early fruiting of side vines, when the main vine has 5 to 6 true leaves, it will be timely topping and topping to promote the occurrence of sub- vines. After the vine spreads, select 1 to 2 sturdy climbers, and when the cranberry grows to a height of 1.5 to 2 meters, try to top it out. After the rest of the vines are sitting on the melons, leave 2 to 3 leaves to pick them in time. In this way, the yield of the early melons can be increased and the subsequent melons can be maintained. In order to maintain the ventilation of the leaf vines, the lower vines should be cut off in time, and the old leaves, diseased leaves and weak branches should be removed. 5. Hormone treatment: Under normal temperature, female flowers in the early stage of the 1st round of the Cymbortium have less female flowers and less male flowers. In order to improve the rate of the seated cucumber, artificial pollination must be performed. The melons bloom in the evening and artificial pollination should be done in the evening or in the morning. A male flower can pollinate 3 to 5 female flowers. If the male flower is not enough, the zucchini male flower can be used instead. At the same time, it can spray pesticides to protect the fruit. During the middle of the melon period, male flowers gradually increased. At this time, open-field cultivation can be conducted without artificial pollination and insect pollination; greenhouse cultivation still requires artificial pollination. In the case of many rainy days, less female flowers are sprayed with 150 mg/L ethephon 1 or 2 times, which can greatly increase the female flower rate. 6. Harvesting: Round No. 1 can be harvested on the 10th to 13th day after flowering and pollination of female flowers and 500g on tender cucumis. At lower temperatures, the fruit develops slowly and can generally be harvested 15-20 days after flowering. 7. Pest Control: The main pests and diseases of the melons are powdery mildew and aphids. Powdery mildew can be controlled by 15% triadimefon, and 40% dimethoate or 40% vending can be used to control aphids.
