Ma Fangying, Changli County, applied grafted cucumber seedling raising technology to obtain high yield, disease resistance, melon yards, melons, white green, small tumors, white thorns, and average melon length 25 to 30 cm. Horizontal diameter of 3 to 3.5 cm, sweet and crispy effect. This technique is described as follows:
First, the choice of varieties to choose black seeds or white seed pumpkin as rootstock, the rootstock grafting affinity, cold resistance, high temperature, strong root growth, water absorption capacity, grafted Ma Fangying cucumber no pumpkin odor. With seeds every other year, the germination rate is higher, and the germination rate of the seeds will be greatly reduced in the year and two years later.
Second, seed processing
1. pumpkin seeds, mu 1.5 kg, the seeds first soaked in cold water for 15 minutes, remove and then placed in 60 °C ~ 65 °C hot water in the hot species for 15 minutes, stirring constantly to heat evenly When the temperature dropped to 30°C, the seeds were soaked at a constant temperature for 8 hours, and the seed pods were washed to remove the surface mucus. In the absence of direct light at the planting of 14 to 16 hours, placed in 28 °C ~ 30 °C under the germination, sooner or later with 30 °C warm water washing 1 time, buds grow 1-2 mm when sowing.
2. Ma Fang camp dry cucumber seeds, mu seed amount of 150 grams, the seeds first soak in cold water for 15 minutes, remove and then put in 55 °C hot water for 15 minutes, stirring constantly until the temperature drops to 30 °C soaking at a constant temperature of 4 to 6 hours, and then packaged in a clean container of gauze (can not have oil), germination at 28 °C ~ 30 °C, 24 hours after the seeds can be sown white.
Third, seedbed preparation
1. Seed bed with washed river sand or prepared nutrient soil, bed soil thickness 8 cm. The sand bed emerged quickly and raised easily, but the temperature changed greatly and the seedlings were susceptible to damage. Nutritious soil as seedbed, seedlings are not easy to get sick, but the growth rate is slightly slower, if the soil is sticky, it is easy to hurt the root when raising seedlings.
2. Grafting seedbed must use nutrient soil, seedling soil thickness of 12 cm, width of 1 meter is appropriate, too wide the middle of the seedlings difficult, the length can be determined according to seedlings.
Fourth, sowing seeds first broadcast pumpkin seeds, 3 days after the broadcast Ma Fang camp dry cucumber seeds, pumpkin and Ma Fang camp dry cucumber are broadcast on the seedbed.
V. Grafting of Ma Fangying's dry cucumber is generally based on the method of connection, using tools such as blades, bamboo sticks, and grafting clips. When the first half of the pumpkin leaves are unfolded, the Ma Fang Camp cucumber seedlings just pour out their hearts. When the pumpkins and cucumbers are 7 to 8 cm in length, remove the pumpkin growth points with bamboo sticks. Use 0.8 to 1 cm away from the top. The blade is cut diagonally from the top to the bottom. The blade surface is parallel to the cotyledons. The angle between the blade and the stem is 45 and the depth is half of the diameter of the stem. Then, next to the Ma Fang Camp Drying Cucumbers from below the cotyledons, the knife surface and the cotyledons vertical, from the growing point 1.2 to 1.5 cm, with a blade from the bottom up and cut a knife, the blade and stem angle of 30, the depth of stem At the 2/3 place, put the pumpkin and cucumber together at the incision so that the cucumber cotyledon presses on the pumpkin cotyledon and is in a cross shape. Use a grafting clip to fix the interface, plant the seedlings as soon as possible, buckle on a small shed, and keep warm. Moisturizing, but also shaded in the first 3 days. When transplanting the seedlings, the grafting clips should be placed in the same direction and the rootstocks and the scion rhizomes should be separated to facilitate the subsequent root cutting. The height of the soil should not exceed the wound, and do not pour into the wound when watering so as to avoid infection of the wound.
