Problems solved by technology

But this method is labor-intensive, time-consuming, and the effect is not obvious; in the existing technology, the most widely used is to spray GA3 at the flowering stage. Causes jujube hanging to accelerate growth and form nutrient competition, causing young fruits to fall off easily, especially in arid areas affected by air humidity, the application effect is unstable
Judging from the use in the past 30 years, jujube farmers increase the number of sprays to increase fruit setting under high temperature, drought and no rain weather, resulting in a large number of jujube fruit setting in the early stage, excessive nutrition consumed by the tree body, and young fruit in the later stage. Shedding more
The aggravation of jujube blackhead disease caused by excessive or repeated application, and the increase of Pipi jujube have become the key issues affecting the income of jujube farmers
Among the regulators for promoting fruit setting of jujube trees, 5-ALA, 6-BA, B9, 2,4-D, IAA, etc. also have certain effects, but they all have serious fruit drop in the young fruit stage, burning leaves, burning flowers, and inhibiting young fruit. Disadvantages such as swelling, insignificant effect, and instability

Abstract

The invention discloses a nutritional chemical agent for increasing the fruit setting rate of winter jujube. The nutritional chemical agent is characterized by being composed of a nutritional agent and a chemical agent, wherein the nutritional agent is prepared from, by weight, 37.5-41 parts of EDTA boron, 9-12.5 parts of glucose powder and 48-52 parts of chelated microelements, and the chemical agent is prepared from, by weight, 1.5-2 parts of compound sodium nitrophenolate, 1-2 parts of brassin and 1-2 parts of gibberellin. The invention further discloses a preparation method and a use method of the nutritional chemical agent. The nutritional chemical agent has the advantages that the nutritional chemical agent is low in production cost, convenient to use and suitable for winter jujube trees; a fruit setting agent can be freely mixed with water, and use is convenient; it is only needed to spray the nutritional chemical agent once in the whole flowering and fruit setting period of winter jujube, and thus the agent and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of jujube-specific growth-regulating nutrient medicaments, and relates to a nutrient medicament for improving the fruit setting rate of winter jujubes, a preparation method and a use method. Background technique [0002] Dongzao is a cultivated variety of jujube tree. It is an excellent late-maturing and fresh-eating variety of thornless jujube tree. It is also recognized as the best-quality fresh-eating jujube variety. Winter jujube fruit weighs 12-14g, the peel is ocher red and bright, the skin is thin and the meat is crisp, sweet and fragrant, rich in nutrition, and the edible rate reaches 95%. Compared with other fruits, winter jujube is also rich in vitamin A, vitamin E, potassium, sodium, iron, copper and other trace elements. The content of vitamin C is 70 times that of apples and 140 times that of pears. It is known as the "King of Hundred Fruits" and "Living Vitamin Pill". In addition, it is rich ...
