1. Planting time
The best cultivation time of potted plum is June-April and July-June. Li grew and developed fastest in these two periods. So the seeds planted are also easy to germinate and take root. The air humidity and temperature are suitable, and the survival rate of potted plum blossoms is very high.
2. Soil preparation
Soil preparation is also very important. Although this plant is not very picky about the soil, in general, if it is allowed to grow in comfortable soil, it will take root and sprout faster. Therefore, humus soil, vegetable garden soil and sandy loam need to be mixed together for preparation. This kind of soil is loose, fertile and acidic.
3. Seed treatment
The seeds of plum trees need to be treated to obtain high germination rate. Therefore, the seeds of plum trees should be cleaned without residual soft tissue, and then soaked in warm water at about 40℃ 1 day. When they have absorbed enough water, they can be taken out and emptied for later use.
4. Planting and protection
Sow immediately after treatment. Sow directly into the prepared soil as required, and then cover with a thin layer of soil and water until the soil is completely wet, but be careful not to leave moisture, and the ambient temperature is controlled at about 65438 05℃.
5. Pruning principle
Because plum trees mainly produce short fruit branches and bouquets of short fruit branches, the basic principles of pruning should be light cutting, long standing and optimized ventilation and light transmission. The key point is to cut off dense branches, competitive branches and lush branches on the back of fruit trees, and combine the methods of core picking, branch picking and light twisting of fruit trees to enhance the ventilation and light transmission environment of fruit trees and promote the better differentiation and formation of flower buds.
Generally speaking, young trees and fruit trees should be reformed mainly at the early stage of fruiting to improve yield. Perennial fruit trees and fruit trees in full fruit stage should mainly relieve tree vigor, reduce ineffective consumption of nutrients and ensure high yield. After the full fruit-bearing period and the senescence period, the fruit trees should be rejuvenated by pruning methods such as thinning, cutting and picking, so as to speed up the replacement of new and old branches, cultivate new main branches and fruiting branches, promote the plum trees to recover their vigor, grow new branches as soon as possible, and restore their normal fruiting ability as soon as possible, thus prolonging the fruiting period and increasing the yield.
