Leaf fertilizer for preventing and treating fruit cracking of red jujube and preparing method thereof

Abstract

The invention discloses a leaf fertilizer for preventing and treating fruit cracking of red jujube. The leaf fertilizer is prepared from, by mass, 38-42% of potassium nitrate, 33-36% of ammonium nitrate, 7-8% of magnesium sulfate, 3-4% of mono potassium phosphate, 8.5-10% of anhydrous calcium chloride, 0.7-0.85% of ethylene diamine tetraacetic acid, 0.5-0.65% of ferrous sulfate heptahydrate, 1.5-2.5% of inositol, 0.04-0.05% of glycine, 0.001-0.003% of thiamine hydrochloride, 0.005-0.15% of pyridoxine hydrochloride and 0.005-0.02% of niacin, and the mass sum of components is 100%. The leaf fertilizer for preventing and treating the fruit cracking of the red jujube contains nutrient elements such as potassium, phosphorus, nitrogen, calcium and magnesium, through reasonable matching, the toughness of the red jujube is improved, accordingly, the fruit cracking of the red jujube is avoided, and the weight of the red jujube is increased. The preparing method of the leaf fertilizer for preventing and treating the fruit cracking of the red jujube is easy.

Description

technical field [0001] The invention belongs to the technical field of agricultural product planting, and in particular relates to a foliar fertilizer for preventing and controlling jujube fruit cracking, and also relates to a preparation method of the foliar fertilizer. Background technique [0002] Jujube tree is a well-known fruit tree, which is planted on a large scale, especially red dates in Xinjiang and northern Shaanxi. In recent years, jujube trees in northern Shaanxi often crack fruit due to heavy rainfall during the ripening period of red dates. Cause the phenomenon of reduced production or even complete production, cause huge burden to the fruit grower, therefore, prevent the jujube from cracking and become the top priority of the jujube grower. [0003] At present, the methods of pruning branches and fertilizing in the soil are mostly used to prevent jujube fruit cracking. The specific methods are: (1) pruning branches is mainly to ensure that the jujube tree is...

Problems solved by technology

[0003] At present, the methods of pruning branches and fertilizing in the soil are mostly used to prevent jujube fruit cracking. The specific methods are: (1) pruning branches is mainly to ensure that the jujube tree is well ventilated and the surface of the jujube is dried quickly. The continuous rainfall has a certain effect, which can reduce fruit cracking; (2) Fertilization in the soil is mainly to ensure the nutrients necessary for the ripening of red dates, but the effect of this method to prevent fruit cracking of red dates is not ideal; If the daily cycle is longer, it cannot guarantee better prevention of jujube fruit cracking
