How to improve the low survival rate of bayberry planting?
Today, bayberry (Myrica rubra) shows different value in different fields, and its taste is excellent, so many people love to eat it and it is very popular. However, in many areas, the survival rate of bayberry planting is not very high; not long after transplanting, various problems appear, until the plant dies. The cause of the low survival rate is generally incorrect planting methods, though of course there may be some other factors. Today Qinnong Net mainly analyzes the planting method aspect to show you how to improve the survival rate of bayberry. Let's take a look below.
1. Selection of saplings
When choosing bayberry saplings, we must carefully observe the root system to see whether it is vigorous and full of life. If the roots look rather dry and withered and there are only a few sparse ones, then the probability of such a bayberry sapling surviving is only one percent, so do not choose it. Next, observe the branches and leaves of the bayberry. If the branches and leaves grow relatively luxuriantly, the color is rather green, and they are full of moisture, that shows its vitality is relatively strong and it can be chosen. Next, when planting, the excess branches and leaves on the sapling need to be pruned to reduce nutrient consumption, so that the trunk can absorb more nutrients, and this can also improve the survival rate to a certain extent.
2. Planting conditions
Bayberry has good cold resistance, but its drought resistance is really not up to much. It can survive in an environment with a temperature of minus 8 to 9 degrees without relying on artificial insulation, but under conditions above 30 degrees, if artificial cooling is not carried out, it will die of heat. Therefore, the most suitable environment for bayberry growth is 15 to 25 degrees. If the local temperature can remain within this range, then the survival rate of bayberry planting will also be much higher. Next, it also needs a relatively large amount of water, so it is best to plant it in an area with a relatively sufficient water source.
3. Transplanting time
Although bayberry also sheds leaves, it is green all year round. If the transplanting time is wrong, then the survival rate of bayberry will not be high either. So we generally choose a time when bayberry is just rooting and growing leaves. Bayberry generally ripens in summer, so in autumn and winter it is in a period of slowly entering dormancy. During this period it cannot be transplanted, because its growth power is not vigorous enough. Therefore, we generally choose the spring season when all things revive, that is, February and March each year, for transplanting. At this time its will to survive is also very strong, so after transplanting it can better adapt to the new environment.
4. Planting method
When planting, we need to dig the planting hole as deep and as wide as possible, generally 1 m wide and 80 cm deep, then add a sufficient amount of farmyard manure into the hole as base fertilizer, and at the same time some nitrogen fertilizer can be added as a supplement. In order to improve the survival rate of bayberry, we generally cut off most of the branches and leaves before planting, leaving only the branches and leaves at the top in the middle, and the cut branches need to be wrapped and treated so that they can quickly grow new buds in the new environment. Finally, after planting, watering is needed, generally two to three times a day, until new buds grow on the cut branches, then watering can be stopped.
5. Fertilizer and water management
In the first year after transplanting and until it bears fruit, we generally need to apply fertilizer two to three times a year, mainly nitrogen fertilizer, supplemented by phosphate fertilizer and potassium fertilizer, mainly to promote the growth of the sapling. When it blooms and bears fruit for the first time, farmyard manure and urea need to be applied as a top dressing. During the fruit-setting period, boron fertilizer is mainly used. Finally, during the dormant period each year, soil fertility needs to be replenished to prepare for the coming year.
6. Planting density
Planting density also affects the survival rate of planting to a great extent. Bayberry needs a certain amount of light all year round to maintain normal growth, so the density cannot be too high. The general spacing is 4 to 5 m between rows and 3 to 4 m between plants, so that its growth is not affected. At the same time, in order to maintain normal density, bayberry needs to be pruned at certain times to ensure reasonable density.
