Fruit of grafted fruit pine for several years

Pine is a common kind of saplings in daily life. After planting for a few years, it will produce fruit, which is very delicious and expensive, but it is very popular with people. How many years does the grafted fruit pine bear fruit?

First, how many years will the grafted fruit pine bear fruit?

Grafted pine can produce pine tower after growing for 12 years, and each tree can produce 1 jin of pine seed in the first year. After that, the yield of pine seed will increase gradually. Pine seeds usually mature from October to November and will not be available in December.

Second, how to graft the old pine stakes?

1. The methods of grafting include bud grafting, branch grafting and leaning grafting. Buds can be grafted from October to February of the second year of the lunar calendar, depending on the difference in local temperature, as long as the autumn buds of five-needle pine grow until they sprout. Cut the stout autumn bud at the top, grow 3 cm-5cm, cut the lower part of the bud into horseear shape with a sharp knife, the length is more than half of the bud length, be as long as possible, the cutting surface is long, the contact area of cambium is large, and then heal well. The second knife is cut at an angle of 30 degrees on the back of the first knife, and the length is 2/3 of that of the first knife. Then insert the five-needle pine bud and tie it with a plastic belt at the cambium, loosening and tightening moderately to expose the bud head. In the future, the pine pile will be placed in the sunny ventilation place for normal management, without shade, we should pay attention to observe the bud head, sprout and grow up to indicate that it has survived, and then relax the plastic belt in time to avoid being embedded in the tree to cause damage.

2. Branch grafting in the eighth month of the lunar calendar, choose the top strong branch of the five-needle pine as the scion, about 7cm in length, and connect it to the pine pile in the same way as bud grafting, and then cover the plastic film tube with a straight diameter of 12cm at the interface, length 15cm, first tighten the lower mouth, and put moss or loess inside to moisturize. Then fasten the upper mouth to expose the pine head with five needles. Management should pay attention to maintain the humidity in the plastic bag, too dry can use syringes to inject water into the bag, if it is found that new buds grow out of the pine head indicates that it has survived, it is necessary to remove the plastic bag into the normal management in time.

3. Bud grafting and branch grafting should pay attention to the interface position and direction, and choose the root of the pile branch, because most of the grafting sites will swell later. If the branch is thick and swollen in the middle, and it should be connected to the left or right side of the branch or under the branch, because the pine shape is often used to hang the branch, if it is connected to the top, it is difficult to shape in the future. In addition, it is necessary to properly cut off too many wild branches and leaves, one is to make the scion accept sunlight to enhance photosynthesis, and the other is to make the pile head improve the affinity to the scion due to the lack of leaves. After receiving work, it is also necessary to control the number of wild branches and leaves to promote the growth of five-needle pine, and only when the five-needle pine grows to a certain number can the wild tree be cut off gradually. if it is cut off prematurely, the whole leaf area is too small, which will kill the whole tree.

4. Compared with branch grafting, bud grafting procedure is simple and convenient to manage, but only leaves grow in one year after survival, and it is difficult to control the length of the branch in the third year. And the branch itself is the branch power without the above error, but the grafting procedure trouble management requirements are high, so there are not many users.
