Summer high temperature and high humidity pear tree management
Drainage and prevention of pear trees need to be pre-set when constructing a garden. In the plain areas, open drains are generally used, and the mountains can be drained using contour lines. If there are no drainage channels and there is a lot of rainfall and water has accumulated in the pear orchards, ditches should be dug immediately to drain the accumulated water.
The cultivating tillage cultivator is an effective way to reduce the soil moisture content, so cultivators should be cultivated after heavy rain, in order to achieve the purpose of drying, loosening soil and promote root absorption. The cultivating depth is 20 cm, and the number of cultivating depends on the soil quality and precipitation of the pear garden.
Appropriate fertilizer supplementation such as nitrogen, phosphorus, potassium and other suitable fertilizers in the rain-fed season is favorable for tree growth and fruit development, and has an accelerating effect on improving fruit quality and flower bud differentiation. However, if topdressing is too much (especially available nitrogen fertilizer), it will cause new shoots to grow long, leading to canopy closure, fruit flavor fade and other issues.
Pest prevention and control of high humidity can easily lead to the occurrence of diseases such as meteorites, and it is necessary to spray pesticides in time after the rain. The commonly used agents are thiophanate-methyl, diniconazole, and Bordeaux mixture. Insect pests mainly include Tenebrio molitores, Pyrosphaeridae, and so on. Imidacloprid, schizophylline, cypermethrin, etc. can be selected as the kind of insect pests.
Insufficient illumination due to excessive leaf area during summer trimming is not conducive to spraying, nor is it conducive to the formation of flower buds in the next year. First, it is necessary to cut away the long shoots or overly dense shoots on the big branches so that the whole leaves will be uniformly illuminated. In order to prevent the sun from causing sunburn on the exposed center trunk or main branch, it may be appropriate to leave part of the shoot at 15-20 cm to pick it up several times to control its growth and promote flower bud formation.
