Problems solved by technology

[0003] Most of the trace element foliar fertilizers currently on the market are single-element fertilizers. There are very few of two or more than three types, and even rarer are four types. Although the application of a single trace element fertilizer can also have a certain effect , but the absorption efficiency of elements is not high, wasting time and labor, and the high-quality trace element foliar fertilizers used by farmers are almost all imported from abroad. higher
Due to technical limitations, most of the trace element foliar fertilizers produced by domestic manufacturers are in solid form, and very few in liquid form, which cannot meet the urgent needs of my country's fruit tree planting industry.

Embodiment 2

[0067] Embodiment 2 The test effect of compound trace element liquid foliar fertilizer of the present invention on litchi

[0068] In Xili fruit farm in Shenzhen, the compound trace element liquid foliar fertilizer of the present invention was diluted 1000 times to spray glutinous rice cakes with a tree age of about 13 years, which was used in the fruit development period, and good results were obtained. As can be seen from Table 1 and Table 2, the yield increased by 13.8% compared with the control, and the sugar content increased by 6.9% compared with the control.

Abstract

The invention discloses a composite microelement liquid foliar fertilizer, comprising a nutritional ingredient and an auxiliary concentration ingredient; the nutritional ingredient consists of sulfate and polymerizing sodium borate salt; and the auxiliary concentration ingredient is composed of a preservative, a cosolvent, a penetrating agent, a bactericide, a surface active agent and other supplementary materials. The invention meanwhile provides a simple, easy and low-cost preparation method of the foliar fertilizer. The composite microelement liquid foliar fertilizer has both good stability and unfolding property, and can provide enough zinc, manganese, copper and boron nutrients for crops in the meanwhile, all elements interact with one another, crops can absorb the nutrients rapidly,and the nutrient utilization rate is high. The liquid foliar fertilizer has rather low costs, and can save fertilizer and labor costs for peasants.

Description

technical field [0001] The invention belongs to the technical field of agricultural production, and in particular relates to a compound trace element liquid foliar fertilizer applied to fruit trees. Background technique [0002] As we all know, in the growth process of crops, trace elements zinc, manganese, copper, and boron play an important role. Zinc, manganese, and copper have little mobility in crops, while boron is an element that is difficult to move. Zinc plays an important role in promoting the development of crop reproductive organs and improving stress resistance and fruit quality. Manganese is an indispensable participant in photosynthesis of crops. It promotes the conversion of nitrate into ammonium nitrogen by regulating the activity of enzymes, and improves the frost resistance of crops. Copper has a stabilizing effect on chlorophyll and other pigments, which can prevent pigments from being damaged. Copper can also promote the development of flower organs, th...
