Problems solved by technology

[0004] Fruit cracking and fruit drop often occur in winter jujube, which leads to low fruit yield and perishability. This is mainly due to the genetic characteristics of winter jujube itself and insufficient fertilization during cultivation, which leads to poor development of various organs of the plant and fruit cracking, which seriously affects the fruit yield. , limiting the planting and cultivation of winter jujube

Abstract

The invention discloses liquid fertilizer preventing fruit cracking of winter jujubes and a preparation method of the liquid fertilizer. The liquid fertilizer is prepared from 1000 parts of an activeliquid fertilizer base preparation, 12-23 parts of nitrogen, 16-28 parts of potassium, 3-12 parts of phosphorus, 16-32 parts of boron, 15-30 parts of calcium, 1-8 parts of magnesium, 0.1-5 parts of zinc, 0.1-5 parts of molybdenum and 0.1-5 parts of iron; the liquid fertilizer contains 10-21 parts of glycine, 1-8 parts of leucine, 1-9 parts of lysine, 3-12 parts of tryptophan, 1-9 parts of gibberellin, 16-26 parts of organic calcium and 10-22 parts of inorganic calcium salt. With the adoption of the liquid fertilizer, the fruit cracking can be remarkably reduced, fruit quality of the winter jujubes can be improved, and per mu yield of the winter jujubes can be increased.

Description

technical field [0001] The invention belongs to the technical field of liquid fertilizers, and more specifically relates to a liquid fertilizer for preventing jujube fruit cracking and a preparation method thereof. Background technique [0002] Dongzao is an excellent late-maturing and edible variety of thornless jujube tree, and it is also recognized as the best quality fresh-eating jujube variety. Winter jujube fruit also contains more vitamin A, vitamin E, potassium, sodium, iron, copper and other trace elements, which can keep capillaries unblocked and prevent the increase of vascular wall fragility. Curative effect, has the effect of preventing cancer. The nutritional value is the crown of all kinds of fruits, and it is known as "the king of all kinds of fruits". The fruit is medium-large, nearly round, resembling a small apple, uniform in size, smooth on the surface, thin and crisp, light green in the white ripe stage, and then turns from light brown to ocher red. T...
