Sweet cherry rainproof culture method suitable for area between Yangtze River and Huai River

Abstract

The invention relates to a sweet cherry rainproof culture method suitable for the area between Yangtze River and Huai River. The method includes the following steps of firstly, forming ridges, and erecting a rainproof shed; secondly, pouring nutrient solutions on roots of sweet cherries at the end of March each year; thirdly, removing polyethylene films on the top of the rainproof shed on sunny days 7 days before flowering of the sweet cherries; fourthly, picking weak-growth-vigor cherry flowers on sweet cherry trees in the flowering period of the sweet cherries according to the ratio of picked flowers to total flowers being 1:4, and spraying a urea solution with the mass fraction of 0.01% on leaf surfaces and flowers of the sweet cherries according to the spraying amount of 20 kg / mu. According to the method, in the flowering seasons of the sweet cherries in the area between Yangtze River and Huai River from the end of March to the beginning of May, the area between Yangtze River and Huai River is just in the weather-variable seasons after the beginning of spring, it is ensured that the flowering and pollinating process of the sweet cherries is not influenced by rainy weather, the applicability of the sweet cherries to the environment is improved, the fruit setting rate is increased, cracked fruits and malformed fruits are effectively avoided, and the stable and high yield of the sweet cherries is achieved.

Description

technical field [0001] The invention belongs to the field of cherry planting, and in particular relates to a rain-proof cultivation method for sweet cherries applicable in the Jianghuai region. Background technique [0002] Cherry is a fruit with high nutritional value. It has a bright, crystal-clear appearance, red like agate, yellow like fat. The fruit is rich in sugar, protein, vitamins, calcium, iron, phosphorus, potassium and other elements. During the planting process of cherries in the Jianghuai region, the flowering season of sweet cherries in the Jianghuai region is from the end of March to the beginning of May. At this time, the Jianghuai region is in the season of changing climate after spring, which often causes sweet cherries to bloom without pollination, resulting in a low fruit setting rate and a proportion of deformed fruits. Too high will affect the quality and economic value of sweet cherries. Contents of the invention [0003] The purpose of the present...
