Greenhouse cucumber serial connection
In recent years, Japanese vegetable farmers have increasingly used tandem grafting cucumbers. After the cucumbers are connected in series, the wilt disease is not easy to infect, and the survival rate is high. It is not necessary to wrap the strips and the clips, and the effect is better than the connection.
Stringing method is to broadcast the pumpkin first, cucumber when the pumpkin unearthed when planting, when the hypocotyl diameter pumpkin seedlings 0.5 to 0.6 cm, cucumber seedling diameter 0.3 to 0.4 cm, the best in series. When squashing, the seedling height of the pumpkin is 7 to 10 cm (just growing from the true leaves).
The tools in series are bamboo knife and shave blade. Bamboo knife length 13 to 18 cm, diameter 0.5 to 0.6 cm, the tip of a four-angle.
The method of concatenation is to first remove the leaves of the pumpkin seedlings, and then put the bamboo knife incline (blank face) upwards, passing from the main vein of the growing point 0.2 to 0.3 centimeters above the cotyledon of the pumpkin seedlings, through the growing point 0.2 centimeters below and 0.3 centimeters below the other cotyledon so that the bamboo stick just penetrates. When wearing, be careful to break through the growth point, but also avoid the hollow part of the hypocotyl, but do not wear a broken skin. After putting on, put the pumpkin seedling with a bamboo knife, and then use a shave blade to cut 30 to 40 degrees (cut the hypocotyls off) on the cucumber seedlings 1 to 1.5 centimeters without cotyledons, cut 0.7 inches long. ~ 0.9cm, pull out the bamboo knife, cut the cucumber seedlings face down, insert from the hole through the bamboo knife, and use a little force, shake the scion (cucumber seedlings) can not afford to even pick up.
After grafting, bury the pumpkin root in the nutrient soil in the nursery bowl (12 cm in diameter), then pour in warm water at 20 to 25°C, and lay the electric heating line under the seedling bowl. Above the seedlings, two film arches are buckled and the grass curtains are covered at night. The temperature in the arch shed is always kept at 25-26°C, the relative humidity of the air is kept at 80%, and the shade is appropriate when it exceeds 26°C during the day, usually after 3 to 4 days. Scion And rootstocks can heal. After that, variable temperature management can be performed, that is, 26 to 30°C in the morning, 20 to 25°C in the afternoon, 16 to 20°C in the middle of the night, and 12 to 16°C in the latter part of the night. After one week of living, the cucumber seedlings began to grow, and the pumpkin leaves that had not been cut during the grafting process had to be removed in time.
