Plant-derived tree-retaining preservative and use method thereof

Abstract

The invention discloses a natural plant source tree retaining preservative, which is prepared from pigeon pea leaves, bitter orange flower or eucalyptus leaf plant extracts, seaweed oligosaccharide, fulvic acid, water-soluble chitosan and glycolipid. According to the invention, the compounding of the components provides various main efficacy factors for resisting oxidation, inhibiting bacteria, killing insects, regulating plant growth and stress resistance, slowing down separation layer formation and the like, a multi-layer synergistic interaction effect is achieved from enveloping, resistingoxidation, killing and inhibiting bacteria to activating cells to enhance stress resistance, the fruit drop rate in the fruit tree retention period can be obviously reduced, the rotten fruit and fruitdrop rate is reduced, and the fruit quality is kept; and adverse effects on normal physiological functions of plants due to tree retaining and fresh keeping can be remarkably reduced, plant growth and nutrient balance can be adjusted, and environmental pollution can be reduced.

Description

technical field [0001] The technical field of agriculture of the present invention, more specifically, relates to a plant-sourced tree-retaining fresh-keeping agent and its application method. Background technique [0002] The technique of keeping the fruit fresh on the tree refers to the use of plant production regulators, preservatives, etc. and agricultural technical measures to slow down the formation and generation of the detachment layer at the base of the fruit stem when the fruit is about to mature, so that it can be kept on the tree for a long time Does not fall off. By keeping the trees fresh, the fruit harvest period can be delayed, the fresh fruit supply period can be extended, the concentrated listing season can be staggered, the pressure on picking, transportation and storage can be reduced, the fruit supply capacity and quality can be improved, and the income of fruit farmers can be effectively increased. Therefore, it is one of the important problems to be s...

Problems solved by technology

However, the commonly used tree-retaining preservatives have the following problems: 2,4-D is not easy to degrade in the natural state, and its impurities have carcinogenic risks. In 2000, my country clearly banned the use of 2,4-D on all crops; prochloraz It is a broad-spectrum fungicide, which has obvious control effects on the diseases caused by Ascomycetes and Deuteromycetes in various crops. It is one of the main tree-preserving agents currently used. There are residues in the end, which will easily destroy the normal physiological functions of plants and affect the quality of fruits. In severe cases, it will lead to serious consequences of no fruit or low fruit setting rate in the second year.
