Nutritional soil preparation
The fermented pig manure was sifted and sifted, and then mixed with the sieved soil in a 3:1 ratio of soil to fertilizer (5 m3 of nutrient soil for 80 m shed).
seedbed
From the second room into the greenhouse, two nursery beds measuring 5 meters long, 1.5 meters wide and 8 centimeters above the ground were set up. The 80m shed requires a total of 7 nursery beds.
seed
Cucumber seedlings were treated with 60 °C water. First pour the water into a clean container, and then put the seeds into the mix. When the water temperature drops to 25~30°C, remove it, put it in clean water to rub it, remove the slime of the seed shell, then use 30°C water. soak. Cucumbers are soaked for 4 hours before they are removed and wrapped in clean gauze. Then, the upper layer of small quilts is placed in the house during the day and can be put into the greenhouse for germination at night. The temperature cannot exceed 35°C. The air is released once a day and the buds are ready after three days. Black amberjack seeds are soaked for 13 hours in addition to slime, ie they are removed by drying and sowing without germination.
Nursery
Before sowing, the seedbeds were sprayed with water first, and cucumber seeds were sown on the first seedbed. It was necessary to dilute the seedlings as much as possible. In the second seedbed, the black squash seeds should be sown. After the next kind of cucumber seedbed soil 1 cm. Then use 800 times the enemy liquid to dip the cover soil thoroughly, and then on the seedling bed mulch, the incubation temperature during the shed should be controlled at 35 °C, 3 days after cucumber seeding is one-third of the Sen Zinc, methyl thiol Buzu and other liquid spray once. After 5 days, when the cucumber seedlings are out, the temperature in the shed should be controlled at 27°C during the day and 14°C at night. After sowing, the pumpkin seed bed is covered with 2 cm soil, and the cover soil is thoroughly stricken with 500 times the enemy liquid. Then the membrane is inserted into the bamboo arch. The temperature should be controlled at 35°C. After the seedlings are removed, the plastic film and bamboo arches are removed and 400 times methyl is used. Topuzin liquid spray. Pumpkin seedlings are generally sown 5 days later than cucumbers.
grafting
Grafting and should be mastered in the seedling height of 8 to 9 cm, pumpkin seedlings really leaves the beginning of the first true leaves of cucumber seedlings when the first exhibition, grafting as soon as possible, generally used by the graft method, grafted cucumber seedlings spray one day before the drug. When grafting, the two seedlings were first removed from the seedbed, and the pumpkin seedlings were used as rootstocks. From the top of the cotyledon, the knife was placed at a 25-degree angle from top to bottom. The cutting was good and the grafting clip was clamped. Pumpkin seedlings should be placed outside the grafting clips.
Post-grafting management
The grafted seedlings are planted on the whole seedbed at an interval of 1010 cm. The side of the seedling is dredged with water. Be careful not to sprinkle the water on the soil. The buried soil should be controlled at about 27°C during the day and then it should not be late. More than 14 °C, after transplanting should pay attention to pull the straw at any time, adjust the light intensity in the greenhouse, spray every 6 days with chlorothalonil, dexamethasone, thiophanate-methyl 400 to 500 times, after grafting 10 to 15 Days, the cucumber seedlings were transplanted and pulled out six days after the roots were cut off. At the same time, pay attention to changes in the seedlings, use straws to adjust the light intensity and temperature inside the shelter.
Colonization
The best time for colonization is when grafting 3 or 4 true leaves of cucumber seedlings. Planting, according to the spacing of 27 cm, a small row of 40 cm, 80 cm row spacing, ridge height 20 ~ 25 cm is appropriate. When planting, the first true leaf of the seedling shall be directed to the sun side, covered with a mulch after planting, and then poured with water for easing seedlings. The highest temperature in the shed within 5 days after planting does not exceed 35°C.
