For many years, some vegetable farmers in Yutian County grafted them by means of grafting when they planted winter cucumbers. Reliable and easy operation, then easy management, survival rate is high, but after the connection, cucumber easily produce adventitious roots. Every year, it can be seen that a considerable number of shed cucumber roots are rooted. Some vegetable growers think that two roots grow better than one root, and even some sheds simply keep rooting. This is actually wrong.
The purpose of cucumber grafting is mainly five: First, to enhance disease resistance, the second is to increase the cold resistance of plants, the third is to expand the scope of root absorption and capacity, the fourth is to help increase production, and the fifth is to help overcome continuous cropping. However, once the cucumber is further rooted, even if it is delicate, it will gradually replace the function of the pumpkin root because it is a "family" and "positive root." The root of the pumpkin looks stout, but in fact it has gradually lost its effect, thus losing the significance of grafting.
The correct approach is to remove the roots from the roots of the cucumbers when the cucumbers are vine-climbed. Some people cut off the roots of the roots twice, and some even do it after the New Year. Since the cucumber roots have replaced the pumpkin roots, If you cut off the cucumber root, it will cause death.
In view of this situation of overwintering and grafting of cucumber, the author proposes to adopt the method of grafting in cucumber grafting. At present, most watermelons adopt this method of connection, and their survival rate is not low. The key is to manage the humidity in the first 3 days, and it is impossible to let the scion fight too much.
The specific plugging method is: plugging the rootstock squash with the cucumber sowing at the same time, or when the temperature is lower than the cucumber sowing 3 to 4 days. When grafting, take black seed pumpkin seedlings, use bamboo sticks to remove growth points and surrounding true leaves, and insert 5 to 7 mm deep along the main vein of the right cotyledon to the left side of the cotyledons. Do not tie down the rootstock with bamboo sticks. Hypocotyl epidermis is degree. Then take a cucumber seedling 1 cm below the cotyledon and cut it to a depth of 2/3 of the stem, about 5 mm long. Then cut the knife from the other side and cut the embryonic axis into a wedge. Pull the bamboo stick to insert it. You can.
Using this method, the root-cutting procedure is avoided, and the rooting can be achieved after survival. Since the cucumber at the interface is surrounded by the pumpkin stem, it is not easy to produce adventitious roots.
When cucumbers are grafted, they should be watered while being planted. When the seedbeds are full, a small amount of water is poured from the bottom of the plastic nutrient bowl to make the nutrient bowl first penetrate the water and increase the relative humidity of the air. In the first 3 days after grafting, the daytime temperature in the seedbed is maintained at 28°C to 30°C and at night around 20°C. When the temperature of the seedbed is not enough, it is necessary to make up for the temperature. The relative humidity of the air should be maintained at about 95%. When the humidity is insufficient, at noon from the small arch above the open joints, spray water on the shed, the droplets should be small, do not make the wound water, so as to avoid infection. 10:00 am to 4:00 pm Light is shaded when strong. After 3 days, the daytime temperature dropped to 22°C to 23°C and nighttime to 14°C to 17°C. The relative humidity of the air was maintained at 70% to 80%, and the illumination time was gradually increased. After 5 to 6 days, small arch shelters were gradually removed and transferred to normal management. Grafting seedlings are usually 35 to 40 days old.
Nut It is the fruit of a plant. It has a hard skin with seeds inside. The nuts we usually eat are made from these seeds. Nuts are not only available in China, but also abroad. Nuts are not only delicious, but also rich in unsaturated fatty acids, lecithin and so on for our human body has a very big effect, often listen to others say that eating nuts can fill the brain, this is not unreasonable. As a result, the variety of nut snacks we eat is very large and selective,
What kinds of nut snacks are available
Wild walnuts

Two, pecan fruit
Pecans are a type of walnut. Pecan fruit shape is long oval, slightly pointed at both ends, the skin is relatively thin, after peeling the inside of the flesh is larger, and very delicious, relative to the fat content of large walnuts will be a little less, so you can often eat, not afraid to gain weight.
Three, pistachios
When roasted, pistachios have an opening at one end of the shell so that you can peel off the shell and eat the flesh inside. The flesh tastes delicious and crispy.
Four, almond
Almonds have a special taste, some people are not willing to accept. But the effect of almonds is very big, and now a lot of roasted almonds are very delicious, we can also choose to eat almonds when eating dried fruit.
The above nut snacks are the nuts we usually eat more, of course, such as peanut kernel, melon seed kernel, these are actually nuts.
