Greenhouse melon production has become the main vegetable planting category in Panjin area. It not only has a good market, but also has a considerable economic benefit. However, in the past two years, the soil-borne diseases caused by heavy smashing have occurred seriously, which has restricted the development of greenhouse melon production. In order to solve this problem, in 2004, we introduced the technology of grafting muskmelon and carried out experiments and promotion in 24 households of 60 mu of greenhouse muskmelon in 20 Jiazi Village, Tianshui Town, Panshan County. 60 acres of greenhouse Muskmelon average yield 7,470 kg, mu production value of 22,410 yuan, cost per acre to remove 6,000 yuan, net income of 16,410 yuan per mu. The successful cultivation of grafted muskmelon solves the problem of soil-borne diseases and provides a reliable guarantee for the development of greenhouse melons. The cultivation techniques are described below. First, sowing seedlings for the United States, the United St. anvil, No. 1 scion sweet melon. On November 25th, sowing melons were broadcast first, and then stockings were sown five to seven days later. Regardless of scion or rootstock, it is best to use a nursery box with a length of 60 cm and a width of 40 cm as a sowing tool for easy movement and management. When the scion grows to two true leaves, three true leaves are exposed for about 10 days. The rootstock grows to two cotyledons and unfolds the true leaves. After 5-7 days, they are suitable for grafting. Second, the grafting method 1. Preparation before grafting First of all, ready to graft with a shave blade, and then ready for nutrition. The nutrient bowl contains nutrient soil (ie, 60% of river black soil, 40% of decomposed sheep manure or pig manure, and 2 bags of parenting agent). We must also prepare the two-story shed needed after grafting, that is, we must first affix the middle shed to the greenhouse, and then to the small shed in the middle shed, plus a total of three floors of the greenhouse. 2. Grafting methods Grafting methods are best used by grafting. First remove the heartwood leaves, and then cut the half of the stem thickly with a blade 0.5 centimeters below the cotyledons of the rootstock, about 35-40 degrees. The scion cantalis cut obliquely at a height of 1.5 cm below the leaves 2/3 of the stem, about 30 degrees, then close the wounds of the two seedlings, clamped with a grafting clip, and then plant the integrated rootstock and scion together. Nutrition inside. It is preferable that the cotyledons of the next rootstock and the cotyledons of the scion be cross-shaped, that is, the scions should be on top and the rootstock should be on the bottom. When grafting, it is best to choose sunny morning. With the grafting, the seedlings will be put into the small arch shed, and the upper cover paper will be shaded. III. “4 three days†during seedling management The first three days after grafting basically kept the weather conditions of high temperature and high humidity. The daytime temperature is kept at 30°C, and it is kept at about 20°C at night in the middle of the night and at least 13°C-15°C in the middle of the night. The soil temperature is maintained at 17°C-18°C. The second 3 days, according to the growing situation of seedlings, during the day can be gradually into the air around the small arch shed, the temperature can also be properly reduced 2 °C - 3 °C; night as usual management, if some wilted seedlings should be sprayed in time to take a partial shade deal with. In the third three days, small arches around the can be properly opened during the day. The paper on the shed was removed at noon and covered in the morning and at night. However, the paper must be covered at about 3 pm to prevent the death of the seedlings caused by the low temperature. On the third day, see the seedlings have eased and the rootstocks and scions survived completely. During the day, small sheds may not be covered with paper, and they may be uncovered around the corner to enter normal management. At this time, they can be cut off. In order to ensure the survival rate after the root is cut off, one day before the root cut, the hand was used to scoop at the root of the scion, and then the blade was used to cut the root the next day. After root crushing, the scion roots are injured and cannot be exposed to strong sunlight. The management at this time should be the same as the second three-day management, until the seedlings completely recover and grow into new leaves and enter normal management. Basically no fertilizer and irrigation during seedling stage. However, fertilization should be carried out 2-3 times. That is to say, when the true leaf of scion is unfolded, after grafting, the shoots are sprayed once every 3-4 days before planting. When the seedlings grow to four true leaves, the calendar seedling age begins to set in about 40 days. Fourth, the time of colonization and planting is about the beginning of January. The method of colonization is based on sorghum cultivation, which is 20-25 cm in height, 90 cm in width and 6 m in length. Before the planting, 5000 kg of high quality farmyard fertilizer, 20 kg of diammonium phosphate, 25 kg of potassium nitrate, and 35 kg of heavy fertilizer or base fertilizer are applied per mu. The black and white mulch is covered on the surface, that is, the surface is white, absorbs sunlight, and the ridges are black to prevent weeds. The spacing of the plants was two ridges per plant, with a spacing of 25 cm and a row spacing of about 40 cm. After the planting, a small shed was buckled. Fifth, management after planting 1. Temperature management to increase the indoor temperature after the main planting, before the melon period during the day temperature should be maintained at 28 °C -30 °C, does not exceed 40 °C does not release the wind, the night temperature is not less than 17 °C - 18 °C. After the melons are still kept at a higher temperature, during the day at 25 °C -28 °C, 15 °C -18 °C at night, if the night temperature too low melon grows. The grafted sweet melons are also relatively low-temperature resistant, which lays the foundation for promoting root growth. 2. Fertilizer and water management Due to the cold winter when planting, plus the salt and alkali of Panjin soil, it is not appropriate to water or water. In water management, it is usually Sanshui: the first is the colonization of water, the second is when the young larvae reach the egg size, the water is poured into the cucurbit, and the third time is the second pod, and the water is poured into the cucurbit. Each time the water is poured into the gutter, it slowly penetrates into the grate. A total of two fertilizations were performed when the second water was poured and when the two crops were fed. Apply 20 kg of diammonium phosphate and 25 kg of potassium nitrate per acre. Spray leaf fertilizer once every 7 days. Pollination melon is a cross-pollination crop, and there is no single sexual intercourse, in the greenhouse must use artificial and indoor bees to complete the pollination, but the commonly used method is artificial pollination. At 9-10am, with the male flower that was open on the same day, petal was removed from the stigma of the female flower by removing petals. If the male flower was insufficient, a male flower could grant 3-4 female flowers. After the pollination, it is best to mark it so that the fruit ripening period can be calculated. When sitting on melon, try not to use hormone treatment, so as not to cause melon deformity and affect product quality. 4. After pruning and retaining melons, the main vines will be picked up and the four vines will grow after 4 leaves and 1 heart. According to the growing situation, choose 3 from the 4 vines and stay in good condition, then leave 3 vines from 3 vines, continue to see quails on 3 vines, and select melons. Good to leave, bad to eliminate, and leave 2 leaves in front of melon topping. If you continue to produce melons on the new branch of Sun Man, you will have two melons. The yield of the second crop is higher than that of the first crop, but the price is lower than that of the crop. Sixth, harvesting mature melons as much as possible, do not pick melons. Melon maturity should be judged based on pollination date and sugar quality. In addition, the color, pattern, gingival sulcus, and smell of umbilicus should be determined. Harvesting should be carried out with fruit stalks and a stalk cut, gently and gently. In order to improve the grade of melon and facilitate transportation, after picking melons, they should be put on the Internet, affixed with trademarks, and sold in boxes.
