Foliage fertilizer with blossom promoting and fruit retention efficacies

Abstract

The invention discloses a foliage fertilizer with blossom promoting and fruit retention efficacies. The foliage fertilizer is prepared from the following ingredients in parts by weight: 5 to 10 partsof mineral source potassium fulvate, 4 to 10 parts of polyglutamic acid, 20 to 80 parts of disodium octoborate tetrahydrate, 15 to 20 parts of lignin, 50 to 70 parts of urea, 5 to 15 parts of phethalanilic acid, 0.5 to 2 parts of Yun alcohol powder, 1 to 7 parts of adenosine-5'-diphosphate disodium salt, 10 to 15 parts of polyoxyethylene octyl phenol ether and 150 to 200 parts of water. The foliage fertilizer with blossom promoting and fruit retention efficacies has the advantages that the effective blossom promoting and fruit retention can be realized; the fruit tree fruit falling is reduced(experiments prove that the fruition rate can be improved by 13.2 percent to 18.9 percent); in the use process, the foliage fertilizer is diluted by 600 to 800 times; the conventional foliage sprayingis used; the foliage fertilizer can be used before 7 to 15 days of fruit free blossoming or after 7 to 15 days of fruit free blossoming; the use quantity in per mu is 20 to 40g / mu; the foliage fertilizer is ordinarily sprayed twice; the time interval is about 7 days.

Description

technical field [0001] The invention relates to a foliage fertilizer with the effect of promoting flowers and preserving fruits, and belongs to the technical field of fertilizers. Background technique [0002] Flower and fruit drop is a ubiquitous phenomenon in fruit tree production, excessive flower and fruit drop will cause great economic losses, so how to prevent a large number of flower and fruit drop is an important problem that must be solved in production. An appropriate amount of fruit drop is conducive to the growth and development of plants, but too much drop will bring huge economic losses to fruit farmers. [0003] The reasons for falling flowers and fruits are mainly as follows: 1. The tree body is weak and the stored nutrients are insufficient, resulting in poor quality of flower buds, low pollen germination rate, resulting in abortion and shedding of flower organs. 2. Poor pollination and fertilization, insufficient pollination trees, lack of pollinators, unf...

AI Technical Summary

Problems solved by technology

2. Poor pollination and fertilization, insufficient pollination trees, lack of pollinators, unfavorable temperature, continuous rainy weather and other unfavorable climate conditions for pollination will lead to poor pollination and fertilization, and insufficient hormones produced by the ovary will cause fruit drop

3. Nutrient competition, fierce competition for nutrients between leaves, new shoots and young fruits, fruit development cannot get the proper nutrition guarantee and fall off

5. Severe pests and diseases occur, which directly consume a large amount of nutrients of fruit trees, resulting in insufficient supply of nutrients for flowers and fruits
