Yellow skin dinner with naked seedlings or container seedlings. When using bare-rooted seedlings, the seedlings should be watered enough 1~2 days before emergence, so that the roots are not easy to break and the seedlings are easy to emerge. When raising seedlings, dig deep from both sides of the seedling to the tail of the main root, leaving the main root 25-30cm and the lateral root 15-25cm. Long roots should be cut off, at the same time, one-third of leaves and branchlets should be cut off, and the roots should be dipped in mud after germination. Bundle every 25 or 50 trees, and wrap the roots with straw, sacks, plastic films, etc. , and tie it firmly for transportation.
If it is a container seedling, the container and soil column can be kept unchanged and shipped directly. The container is seriously damaged and the soil column is intact, so it can be put back in the same container and tied up. If the soil column is damaged, treat it naked. Grafted saplings should be shipped separately according to varieties and grades. During transportation, it is necessary to prevent sun and rain and ensure ventilation. After the grafted seedlings are transported to the destination, put them in the shade as soon as possible for formal or additional meals. If it can't be planted or eaten in a short time, you can put the grafted seedlings on the scrotum and soak them in water to keep them moist.
Intercropping oil tree has small crown and many gaps between trees, which can intermittently plant short-term crops such as pineapple, watermelon, melon, beans and vegetables, improve early income, optimize feeding environment, reduce land cover, reduce the rapid change of soil temperature and humidity, and reduce the adverse impact on wampee root system. Returning stubble to field in intercropping crops can increase soil nutrients and improve soil fertility. Shady crops can be planted occasionally in surplus period, but they should be harvested before winter, without fertilization, intercropping and bathing.
After the deep transformation of hilly orchards, the soil will be deeply transformed from the second year, and it will be carried out after turning green in autumn and winter every year. (william shakespeare's "Hamlet's Famous Seasons") Dig a ditch under the drip line in the canopy, improve the soil with organic fertilizer, and take turns every year to complete all the excavation work in two or three years.
Dumps and orchards with high groundwater level will be drained once a year to thicken the plough layer. Crops such as soybeans are planted between orchards, and the branches and leaves of intercropping crops can be used as green-breaking materials or covered with boards. Fertilization of young trees should be based on dilute, diligent and nitrogen fertilizer, and mixed application of phosphorus fertilizer, potassium fertilizer and magnesium fertilizer. Fertilize before each shoot and during the period of returning to green, resulting in propulsion and strong buds.
Fruit trees are fertilized three times a year. For the first time, flower fertilizer was popularized around Korea, which delayed the combination of high-efficiency fertilizer and quick-acting fertilizer. The ratio of nitrogen, phosphorus and potassium is 1.03600.53600.8, accounting for about 25% of the whole year. The second marketing department promoted chemical fertilizer in late summer, and applied it before cattle, mainly potassium and nitrogen fertilizer. The annual chemical fertilizer consumption accounted for about 30%. After the third harvest, autumn grass was fertilized, accounting for about 45% of the whole year. Water yellow bark has shallow root system, weak hypoxia, drought tolerance, poor ventilation and yard water accumulation. In my hometown, we should pay attention to drainage in rainy season, prevent artificial forest from accumulating water, keep moisture, and sprinkle water and inject water during drought. After fruit harvest, pay attention to irrigation and drought resistance during autumn harvest.
After the pruned seedlings are officially eaten, they should be cored at a height of 40 ~ 50 cm or chopped and dried to promote the germination of the cut buds. After the stock price index is mature, pick the kernel or cut it short at 15 ~ 20 cm to let the buds under the scissors sprout. Select 2~3 branches with strong strength and reasonable distribution from each stock price index to cultivate the second stock price index. The third and fourth branches were cultured in the same way. Results Pruning of fruit trees was mainly carried out after fruit harvesting. When the fruit is harvested, two branches are left at the bottom for pruning, so as to promote fruit bearing in late autumn and cultivate good bearing seedlings. As a result, if the seedling picks the fruit, the leaves will not be cut off, only all the ears will be cut off. After picking, mainly cut off dead branches, pests and diseases, too dense shade branches, and cut off short and long branches to form a well-ventilated umbrella crown.
