First, there is not enough light. The crown of the big trees around the Myrica rubra tree is too big, which blocks the sun and the Myrica rubra tree can't get enough light.
Second, the soil is too fertile, and the Myrica rubra will only grow vertically, not horizontally, which is not conducive to the results.
Thirdly, the climate is changeable, with snowfall, rainstorm and cold air coming one after another, and spring is the key season for the growth of Myrica rubra, so the climate is changeable, which also affects the growth and fruit of Myrica rubra to some extent.
Fourth, the age has not yet arrived.
Fifth, there are no pollinated male trees.
How to plant a Myrica rubra tree well
1, the shape of Myrica rubra: The tree shape of Myrica rubra mostly adopts the shape of natural turning. Because the terminal bud of Myrica rubra and its nearby 1-4 buds can sprout branches to become backbone branches or lateral branches, the top branches have strong growth potential, and the lower parts are mostly hidden buds, so the crown branches are very regular.
2. Flowering and draining of fruiting branches: Generally, from mid-February to March, for annual trees with excessive flower bud differentiation, the whole tree should be evenly chopped with 1/5 ~ 2/5 fruiting branches, and the thin and dense fruiting branches should be drained. At the same time, 0.5 ~ 1.0 kg of available nitrogen such as urea was applied to each plant to promote the growth of vegetative branches.
3. Chemical flower thinning: For old trees or plants with too many fruits, the flower thinning amount can reach 50% by using the solution of "Shuhua No.6" 100 mg/kg in full bloom, and the fruit shape, early maturity and high-quality fruit rate can be increased, and the number of new shoots and the annual output (seedlings, etc., 1999) can be significantly increased.
In addition, weak trees and trees with too many flower buds can also be sprayed with gibberellin at a dose of 200-300mg/kg every 10 day for 2-3 times continuously, so as to increase the number of autumn shoots and inhibit the formation rate of flower buds.
