In view of the artificial forest without base fertilizer in autumn, preventive measures are taken again and base fertilizer is applied again. Conclusion Pear trees should be dug under the drip line of pear tree trunk every other year, with a depth of 50cm and a width of 50 ~ 60cm, and gradually turned flat. Pruning time: from the beginning of June 165438+ 10 to the end of June of the following year, 65438+ 10. Pruning methods vary with species and cultivation methods. Pruning pear tree is a planting strategy to adjust the growth and development effect of each part of the trunk. Pear orchards are very destructive because of diseases, which is very harmful to the manufacture of pear trees. In order to ensure the growth and quality improvement of pear trees in the coming year, it is necessary to master the comprehensive prevention and control of diseases reasonably, and carry out the prevention and control of pests and diseases immediately after harvest.

Management methods of pear trees in winter. Everyone has the following aspects to analyze. Before the start of winter, everyone has a management method of winter fertilizer and winter water. Before winter, you should dig deep into the soil and fertilize it for the last time. Compost is mainly organic fertilizer. After composting, irrigate winter water once. The problem of pear tree pruning has been solved. Prune in winter. Is to cut off blind branches and introverted branches! Chemical fertilizer spraying on trunk and tree technology. Spray pear trees with agricultural streptomycin or sodium abietate sustained-release tablets once in all directions. That will kill insects and prevent cold!

Pear trees are tolerant to low temperature, drought, waterlogging and salinity. In winter, most places and most species can winter reliably. However, winter supervision is particularly critical. Prevention of diseases: There are two kinds here: human prevention and drug prevention. The purpose of manpower is nothing more than scraping skin, cutting branches, removing dead branches and so on. Let's talk about drug control first: Sprayer 80% poplar 2000 times solution 5% avermectin 8000 times solution chlorpyrifos 1500 times solution can control pear psylla, pear bee, search engine spider, scab and brown spot.

When the number of fruit branches exceeds 50% of the total number of branches, flowers should be thinned, and bracts should be separated before flowering in general. Sooner than later. Spraying 350-400 times borax solution and 400 times urea solution at flowering stage can improve commodity rate. Honey peaks pollinate plantations. Put 1 box honey peak in 1 mu pear orchard, and put it in pear orchard 2-3 days before flowering. In the center, there is no need to spray pesticides before flowering in the plantation pollinated by honey peaks to prevent killing honey peaks. Doing a good job in the management of these fields can ensure a better harvest of pear trees next year. Pear trees have a strong ability to blend into the soil layer, and under the general cultivation and supervision standards, the yield can basically be increased.
