Recently, the weather is dry, cold in the morning and evening, and windy during the day, this article is written by Jiang Shaolong, a senior agronomist in the old town and countryside of Yuanmou County, to explain how to manage orchard farming operations.
First, pay close attention to the end of winter and spring shearing agricultural work 1, thinning. Closed orchards are resolutely thinned. Everything grows on the sun, and without light it does not become a flower. The key to thinning is to make room for root growth to stretch. The inorganic nutrients we apply to fruit trees can be transformed into organic nutrients for fruit trees through root absorption, branch transportation, and leaf synthesis. The blade is the processing plant, and the "light" is the electrical energy of the blade! If the light is not good, everything is not to be discussed! 2. By thinning the closed orchard, create a stretch for the root system to grow, because the root diameter is 2 3 times larger than the canopy.
Second, the fruit tree varieties are different, the strength and weakness of the trees are different, and the pruning methods are different. 1. Cultivate a firm skeleton and strictly control the branch-to-stem ratio. 2. Pruning long branches, mainly putting, cultivating large and medium-sized fruiting branch groups, and the branch groups are not weak and do not return to prune. 3. Pruning short branches, full flowers, capped, retracted. Cultivate small and medium-sized fruiting branch groups and eliminate chicken claw branches. 4. Strong trees are pruned by partial potential to increase the growth point, slow down the growth potential, and promote their flowering and fruiting. 5. Weak trees should be pruned together to reduce the growth point, that is, it is better to increase grain than to reduce the mouth, promote its branches, and restore the tree potential. 6. Branch group preparation: the large, medium and small collocation is reasonable, and the upper, middle and lower parts are staggered. 7. Strictly control the branch-to-stem ratio. When the long branches reach one-third, they must be thinned; Short branches are best controlled at one-quarter to one-eighth. The branches are better than the best to train into grandfathers and grandchildren. As long as the branches are balanced, the tree is balanced, and the tree is strong, it lays a solid foundation for the production of high-quality fruits.
3. Scraping the bark of the fruit tree in the spring to treat rot disease 1, rot disease is a weak parasitic bacteria, bullying the soft and afraid of the hard, the tree is not weak and not infected, there is no wound and no infection, and there is no frostbite and no disease. 2. Early curettage, application, and sealing. If you find that the rot disease is low and the sap is not flowing, you should scrape and treat it as soon as possible. After scraping, apply 300 times star + silk sterilization, and then seal with healing agent. 3. Physical clearing of the orchard. Remove the dead branches and leaves, gently scrape the rough bark of the fruit tree trunk, and reduce the base number of pests and diseases, writer: Jiang Shaolong.
