Foliage fertilizer

Abstract

The invention relates to a foliage fertilizer. The foliage fertilizer is characterized in that the foliage fertilizer comprises the following compositions in weight percent: 20 to 30 percent of potassium citrate, 1 to 2 percent of ferrous sulfate, 1 to 5 percent of manganese sulfate, 1 to 2 percent of bluestone, 1 to 5 percent of ammonium molybdate, 1 to 5 percent of surfactant, 1 to 5 percent of complexing agent and the balance being water. The potassium citrate, micro-fertilizer and the surfactant are compounded to form the foliage fertilizer which has nutritive substances essential to the growth of plants. The compounded foliage fertilizer has strong wetting capacity, is sprayed on the leaf surface of the plant and is absorbed by the plant through corneum, or unkeratinized guard cells or pores of the leaf surface, thereby improving the utilization rate of the fertilize effect and the supplementation of the micro-fertilizer; and the fertilization method has low cost and rapid effect, and is simple and convenient.

Description

Technical field [0001] The invention relates to the technical field of chemical fertilizers, in particular to a foliar fertilizer. Background technique [0002] The compound foliar fertilizer is mainly based on the physiological conditions of the plant, and the nutrients pass through the stomata on the back of the leaf to the mesophyll tissue and cuticle, and then enter the epidermal cells. In fact, most of the nutrients such as carbon, hydrogen, oxygen, and sulfur needed by plants are supplied by carbon dioxide, water, and sulfur dioxide in the air. The main purpose of spraying foliar fertilizer is to avoid the loss and transformation of nutrient elements in the soil, and directly provide nutrition for plants. As a kind of liquid fertilizer that strengthens plant nutrition, foliar fertilizer has the characteristics of low dosage and high utilization rate, especially in the early and late stages of plant growth when the root absorption capacity is poor, and can replenish nu...

Problems solved by technology

In recent years, most of the foliar fertilizers produced and promoted in China have low effective content, single nutritional function, poor auxiliary moisturizing degree, low utilization rate, and insufficient stable effect. Some of them cannot be mixed with other chemicals when used, which increases the labor and investment of farmers. investment, and the effect is not obvious enough
