Method for preventing fruit cracking of pear trees before pickup

Abstract

The invention discloses a method for preventing fruit cracking of pear trees before pickup. The method comprises the following steps: A, boron spraying in the flowering phase: spraying borax aqueous solution onto flower stalks and receptacles of the pear trees from bottom to top and inside to outside in the early blooming phase; B, CaCl2 aqueous solution spraying in the young fruit phase: after flowers fall, spraying CaCl2 aqueous solution onto the blades and young fruits of the pear trees from bottom to top and inside to outside; GA3 spraying in the fruit expansion phase: spraying GA3 aqueous solution onto the blades and fruits of the pear trees from bottom to top and inside to outside in a sunny day in the fruit expansion phase; and D, black gardening ground fabric covering: covering black gardening ground fabric on row zones of the pear trees in childbearing period, flatting the row zones of the pear trees, covering black gardening ground fabric matched with the row zones in height and width on two sides of the row zones of the pear trees in parallel, and burying the two sides of the black gardening ground fabric with soil. The method is easy to implement, simple and convenient to operate, can remarkably reduce fruit cracking of pear trees before pickup and can control the fruit cracking rate to be within 5%.

Description

technical field [0001] The invention belongs to the technical field of fruit trees, and more specifically relates to a method for preventing pear tree fruit cracking before harvesting. The method can effectively solve the problem of pear tree fruit cracking before harvesting in pear scientific research, breeding and production. This method is suitable for scientific research units, companies and individuals engaged in pear scientific research, breeding and production. Background technique [0002] Pear belongs to Rosaceae (Rosaceae) Apple subfamily (Maloideae) Pyrus (Pyrus) plant, is the deciduous fruit tree of Qiaoben, is one of three major cultivated fruit trees in my country, and also occupies a pivotal position in the world. According to the statistics of China Yearbook, in 2010, the pear planting area in my country was 10.631 million hectares, and the output was 15.0571 million tons, ranking first in the world. Pear production has always been an important pillar indust...

[0003] However, the pear varieties such as Zhongli No. 1, Huangguan and Cuiguan, which have a relatively large cultivation area, often suffer from fruit cracking in production, especially from late May to early June, when there are severe droughts and showers, the fruit cracking rate can be high. up to 20% to 30%, and up to 50% to 60% in severe cases, seriously affecting the commodity value of the fruit and bringing huge economic losses to producers
