Special anti-cracking foliar fertilizer for jujube tree, and preparation method and application thereof

Abstract

The invention discloses a special anti-cracking foliar fertilizer for a jujube tree, and a preparation method and an application thereof. The special anti-cracking foliar fertilizer for the jujube tree is composed of the following components in percentages by mass: 5% to 8% of potassium chloride, 7% to 15% of calcium chloride, 1% to 5% of borax, 1% to 5% of chelated magnesium, 1% to 3% of chelatediron, 0.5% to 1.5% of zinc sulfate, 0.2% to 0.6% of manganese sulfate and 3% to 4% of organosilicon, with the balance being water. The foliar fertilizer provided by the invention has low production cost, is safe and effective, and is beneficial for and harmless to human and livestock; mineral elements added in the foliar fertilizer are needed by animals, and can effectively prevent a variety of diseases like yellow-leaf disease and little-leaf disease caused by nutrient deficiency of a fruit tree; the disease resistance of a tree body is strengthened; the quality of a fruit is improved; the soluble sugar content of a fruit is improved by 14.3% to 43.5%, the weight of a single fruit is increased by 5% to 13.3%; the proportion of high-quality fruits is increased by 20.2% to 69.8%; the proportion of low-quality fruits is decreased by 28.9% to 76.9%; the fruit cracking rate of golden-silk jujube is significantly decreased by 30% to 45%; meanwhile, the contents of mineral elements in fruits and leaves are significantly improved; and the foliar fertilizer is free of any side effects, is safe and reliable, and is a green and environment-friendly product.

Description

technical field [0001] The invention relates to a special anti-crack foliar fertilizer for jujube trees, a preparation method and application thereof, and belongs to the technical field of agricultural fertilizers. Background technique [0002] Leling golden jujube has a production history of more than 3,000 years. Leling City, Dezhou City, Shandong Province has an excellent environment suitable for the growth and development of golden jujube. The cultivation area of ​​golden jujube in this area reaches 300,000 mu. In recent years, the golden silk jujube industry is facing a serious production crisis. The fruit production and quality have declined, which has caused great economic losses to the jujube farmers. The hard management of the jujube farmers for a year ended up making ends meet, which seriously affected the development of the golden silk jujube industry. .

AI Technical Summary

Problems solved by technology

In recent years, the golden silk jujube industry is facing a serious production crisis. The fruit production and quality have declined, which has caused great economic losses to the jujube farmers. The hard management of the jujube farmers for a year ended up making ends meet, which seriously affected the development of the golden silk jujube industry.

[0003] Analyzing the reasons, on the one hand, due to climatic factors, the ripening period of Jinsixiaozao fruit is constantly cloudy and rainy, coupled with the influence of morning dew, resulting in serious fruit cracking problems, reducing fruit quality, resulting in a decline in profitability, and heavy losses for jujube farmers

In 2013, Jinsixiao jujube in Leling City experienced serious fruit cracking, and the yield was reduced by more than 70%, which caused huge losses to local jujube farmers

In 2014, due to severe fruit cracking, Jinsixiaozao in this area experienced a phenomenon of high yield but not a good harvest. According to survey statistics, the average fruit cracking rate in 2014 reached 72%, which greatly reduced the sales price of Jinsixiaozao, and the income of jujube farmers was meager for two consecutive years. Even making ends meet, causing some jujube farmers to lose management confidence, which has a negative impact on the sustainable development of the local jujube industry

According to the survey, the Laoling area is a saline-alkali area, and the soil compaction is very serious. Some elements in the soil, such as iron, calcium, magnesium, and zinc, are easily fixed by the soil, which is not conducive to root absorption.

The lack of these elements will reduce the quality of flower buds and fruit quality of fruit trees; these factors are the reasons for the decline in quality of jujube and serious fruit cracking

[0005] In view of the above problems, there is an urgent need to provide a foliar fertilizer suitable for the production of Leling Jinsixiaozao, and topdressing outside the roots, in order to effectively solve the actual production problems of Leling Jinsixiaozao, such as fruit cracking and quality decline.
