How to improve the fruit setting rate of pear trees when pear trees are planted seriously? A pear tree planted by a fruit farmer in the Shangrao area of ​​Jiangxi Province showed a large number of fruit drop in late May. Why did you not be able to sit down this year? The experts asked him two questions: First, was the base fertilizer applied to the pear trees last fall or was applied this spring? Second, what fertilizer is used for the base fertilizer? How much? He told the experts last year. The yield of these pear trees is relatively high. After the fruit picking in autumn, the base fertilizer is not applied immediately. The base fertilizer is applied only in the spring of this year. The base fertilizer is only applied with urea, and a tree is applied with 0.5 kg of urea. This year's spring and summer, the rain is heavy, and the pear trees are fruitful.
Analysis of agricultural experts: A large number of fruit drop is directly related to improper fertilization. In this case, there are two problems of excessive application of pear tree base fertilizer and nutrient imbalance in base fertilizer.
This pear tree produced higher yields last year. In order to prevent the occurrence of large and small years, it is reasonable to apply base fertilizer in the autumn immediately after fruit picking. That is, before the leaves are combined with autumn tillage for fertilization, autumn fertilization is better than spring fertilization. If the base fertilizer is applied last autumn, this year will not only flower early, but also have a high fruit setting rate, which will also reduce the physiological fruit drop phenomenon.
The benefits of autumn fertilization are mainly to supplement the tree nutrients early and to update the underground roots after a large number of fruit picking, laying the foundation for this year's flowering results. In this case, the fruit yield was high last fall, and the tree nutrient consumption was large. There was no early application of base fertilizer to supplement the tree nutrient. In the coming year, a large number of fruit drop will inevitably occur.
The ratio of demand for NPK nutrients to pear trees is about 1.0:0.4:1.0. Therefore, it is better to apply the combined application of organic fertilizer and chemical fertilizer to the pear tree. If no organic fertilizer is applied, the ternary complex should be applied. Mixing fertilizer or using urea with calcium, ammonium phosphate and potassium chloride to balance the nutrients of nitrogen, phosphorus and potassium is beneficial to the flowering results of pear trees this year.
Pear tree application of base fertilizer is too late, resulting in winter and spring tree body nutrient deficit; spring fertilization and partial application of nitrogen fertilizer, resulting in imbalance of phosphorus and potassium nutrition, in addition to the above internal factors, but also this spring is too large. Such a combination of internal and external causes caused a large number of pear trees to fall this year.
It is recommended to use the method of spraying potassium dihydrogen phosphate and borax directly outside the root to properly relieve the fruit drop. At the same time, the method of soil topdressing should be adopted as soon as possible, and the appropriate amount of ternary compound fertilizer should be ditched into the soil in order to gradually solve the fruiting period. Nutritional issues.

Vitamins are a type of trace organic substances that humans and animals must obtain from food in order to maintain normal physiological functions. They play an important role in human growth, metabolism and development. Vitamins do not participate in the formation of human cells in the body, nor do they provide energy for the human body.
