Green labor-saving chemical fertile orange flower and fruit thinning method

Abstract

The invention belongs to the technical field of fruit tree cultivation, and discloses a green labor-saving chemical fertile orange flower and fruit thinning method. A flower thinning agent is sprayed 2 days before the flowering period of fertile orange; and / or a fruit thinning agent is sprayed 1-2 days after flowing; wherein the flowing thinning agent is sodium rosinate or calcium formate, and the fruit thinning agent is sodium rosinate or naphthalene acetic acid. According to the green labor-saving chemical fertile orange flower and fruit thinning method, the chemical flower thinning and fruit thinning method is used instead of artificial flower thinning and fruit thinning to regulate the yield of the fertile orange, so that the fruit setting rate of the fertile orange is reasonably reduced, the task of artificial fruit thinning is reduced, and the cost of fruit thinning is greatly reduced. The green labor-saving chemical fertile orange flower and fruit thinning method can satisfy the normal growth of citrus trees, reduce the loss of unnecessary tree nutrients, prevent the occurrence of the phenomenon of one year of high yield and one year of low yield, control and stabilize the yield, improve the fruit quality, and increase the comprehensive income of the orchard.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a green mandarin orange labor-saving method for thinning flowers and fruits. Background technique [0002] Citrus is one of the main fruit tree varieties in the world. There are 135 countries and regions producing citrus in the world, and more than 40 countries mainly produce citrus. The annual world trade volume exceeds 65×10 8 The dollar, is the third most traded agricultural commodity. The latest statistics show that China, India, and Morocco are the countries with the fastest growing citrus planting area in recent years. The citrus industry has become a pillar industry for my country's regional economic development and will play an important role in the implementation of my country's rural industrial poverty alleviation and rural revitalization strategies. effect. Due to the relative overcapacity of domestic mid-ripening citrus production and the c...

Problems solved by technology

Traditional chemical flower and fruit thinning agents for fruit trees, such as lime sulfur, ferrous sulfate, calcium-containing compounds, and edible oils, mainly reduce the fruit setting rate by causing damage to organs or tissues such as stigmas, pollen, and ovaries. All these chemical reagents or formulas have the disadvantages of general flower thinning and fruit thinning effect, high toxicity or large damage to plant tissue, and single effect. Such chemical flower thinning and fruit thinning agents are less widely used in production, especially in There are very few applications in citrus production control
