Method for improving fruit setting ratio of Zuili

Abstract

The invention relates to a method for improving percentage of fertile fruits of local plum, which comprises the steps of: 1. shading treatment, wherein the shading treatment is carried out on local plum trees from the middle third of July in summer to the last third of October, and at least one layer of shading screen with the light transmittance of between 45 and 80 percent is arranged above the local plum trees; and 2. gibberellin treatment, wherein at least one time of spraying the gibberellin with the concentration of between 50 and 150ppm is carried out from the middle third of September to the last third of October. The shading screen is a layer of netty object with the light transmittance of between 46 and 65 percent, the concentration of the selected gibberellin is between 60 and 120ppm; and the shading screen can also be two layers of netty objects with the light transmittance of between 65 and 75 percent, and the concentration of the selected gibberellin is between 60 and 120ppm. The method has the characteristics of simple and reliable method, obvious improvement on the percentage of fertile fruits of the local plum trees, improvement on the yield of the local plum, and so on.

Description

technical field [0001] The invention relates to a method for increasing the fruit setting rate of Prunus chinensis, in particular to a method for increasing the yield of Prunus chinensis, which belongs to the planting method of fruit trees. Background technique [0002] Plum is a honey plum type, rich in iron and vitamin B, with a soluble solid content of more than 16%, which can reach 21% after ripening, sugar content of 14-22 degrees, and acid content of 0.75-0.95%. And contains a variety of vitamins and calcium, iron and other minerals. The fruit matures in mid-July and is flat in shape. The color of the peel is like rouge, beautiful and bright, the peel is thick, rich in toughness, the flesh is dense when ripe, sweet and fragrant, crisp and refreshing. For fresh food, one of the high-quality fruits that consumers love in summer. [0003] It has been cultivated in Zhulin and Tongxiang in Jiaxing, my country for more than 2,500 years. According to legend, during the Spr...

Problems solved by technology

Due to the above-mentioned reasons of the plum itself, and the slightly abnormal external environment during the flowering period, it will lead to the growth speed of pollen tubes and the ability of pollination and fertilization, which will eventually affect the fruit setting rate and yield.
