Several problems that should be paid attention to in planting Golden Pear

The main results are as follows: 1. garden site selection: Golden pear has poor resistance to drought and barren, so the garden site should choose the place where the soil layer is thick, and the barren soil is not suitable for planting.

2. Plant-row spacing: young golden pear trees are easy to blossom, bear fruit early, grow slowly, and can be planted densely. The reasonable plant-row spacing for its cultivation is 2mx2.5--3m. Determining its reasonable plant-row spacing can not only use the land reasonably and economically, but also increase the unit area and yield of golden pear and obtain higher economic benefits.

3. Configuration of pollination trees: Golden pear is a variety with no pollen or little pollen, so double pollination trees should be matched when the garden is established, and excellent varieties such as Huangguan, emerald (Zhongli No. 1) and Xingshui should be selected.

4. Humidity: Golden pear has a very strict requirement for moisture, so it is necessary to keep the soil moisture relatively stable. Drought and no rain should be watered to avoid permanent wrinkle fruit (toad fruit).

5. Artificial pollination: the fruit of artificial pollination is larger and of better quality than that of natural pollination. Therefore, artificial pollination at flowering stage can not only increase the yield, but also an important technical measure to improve the commodity quality of fruit.

6. Bagging: the production of high-quality and high-grade golden pears must be bagged, and bagged twice, first with small bags and then with large bags. Small bags should be glossy paper bags. In the middle and late May, it is best to use a double-layer paper bag with outer white and inner yellow or outer yellow and inner white, the pear is the most popular light yellowish green, and the pear covered by the black paper bag is yellow and white. Cover the big bag in early July, but you must remove the small bag and then cover the big bag. In addition, the more strict the sealing of the bag, the better. It is better for the bag to be wrapped on the handle than not. When bagging, you should choose high-quality fruit bags, inferior bags are better than no bagging.

7. Fruit thinning: 1 fruit per 30--35cm. One week after flowering, there is a clear distinction between calyx-free fruit (female pear) and non-calyx fruit (male pear). It can be combined with sparse fruit and non-calyx fruit. For a large and well-positioned perennial calyx fruit, the calyx can be removed with an one-sided razor, but the wound should be flat and do not hurt the top of the young fruit, or 15% PP3337000--10000 times can be sprayed with a small sprayer 3 days after artificial pollination, which can effectively remove the calyx and make all the fruit become a "mother pear" without calyx.

8, timely update: the golden pear is easy to senescence prematurely after the result, so it should be retracted in time after the result.

9. Timely pest control: the most important thing is to do a good job in the control of pear planthopper, focusing on the period from mid-late May to early June. The medicament is 5000 times imidacloprid + 8000 times imidacloprid + 1300 times phosphates 3, and the control effect can reach 90%.
