Temperature Control and Prevention of Diseases and Pests in Fruit Season
During the warming season, the temperature and the temperature of the fruit trees will be controlled. As the temperature rises, fruit trees will gradually enter a period of vigorous growth. At this time, strengthening management will help promote the expansion of young fruit and lay a solid foundation for increasing production and income. However, the increase in temperature and the increase in humidity can easily lead to the prevalence and spread of fruit tree pests and diseases. In order to effectively control the outbreak of fruit and plant diseases and pests, and reduce and reduce pests and diseases, prevention and control of fruit tree pests and diseases should grasp the following points: 1. To renovate the branches, and to pull the branches. The main branch of the sapling opens its angle during the growing season, which not only makes the branch angle fixed, but also lays a foundation for a large number of subsequent results, and can ease the tree potential and branching potential and promote flower bud formation. The second is tipping. The use of the promotion of Kaowang 2 to control it, to avoid the traditional methods of tree vigor damage, inhibition of prosperous and promote flowering effect. The third is the thinning. When the canopy is rich, some dense shoots or unusable leggy shoots can be removed to improve lighting conditions. When paying attention to the branches, we must pay attention to straight stay, go weak, and stay strong. 2. Completely remove the stubs, residual fruits or landing branches under trees and trees, and bring them out of the park to be burned or buried deeply. In the surface of the fruit tree is sprayed with general tree maintenance, asphyxiating sterilization, to avoid infection and reproduction of the bacteria. 3, after the young fruit enters the expansion period, it is necessary to timely topdressing and watering. Under normal circumstances, mature trees can apply 2 kg of urea, 5-7 kg of ammonium bicarbonate, and 4-6 kg of phosphate fertilizer. The fertilization method can be applied by acupuncture or radiation rays, and timely watering after fertilization. Low-lying land and high-water orchards should pay attention to drainage. 4, the rational use of pesticides: the use of high efficiency, low toxicity, low residue pesticides; according to medication instructions before orchard medication, the correct dilution, the drug should be fully uniform, the back of the leaf should be more fully drug, according to the precise application of medication site; Arbitrarily increase the concentration to avoid increasing the resistance of pests and insects; alternating use of drugs, organic-inorganic pesticides are used interchangeably, and at the same time, more than two types of different agents may be used in combination, and the same agent may not be used consecutively. 2015.10.03 Gelatin Sheet,Gelatin Sheet Leaf,Halal Gelatin Sheet,Edible Gelatin Sheet Hebei Haodong Biological Technology Co.,Ltd. , https://www.hdgelatin.com
