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

Embodiment Construction

[0009] Take by weight 25% of potassium sulfate, 1% of ferrous sulfate, 4% of manganese sulfate, 1% of copper sulfate, 5% of zinc sulfate, 1% of surfactant, 2% of complexing agent, and the rest is water, stirring at a constant speed , stir for 30 minutes, mix well and let stand. Spraying period: 7 days before flowering, 5 days to 7 days after flowering, and fruit expansion period in June, spray once each. When spraying, spray on both the front and back of the leaves, preferably after 4:00 in the afternoon; do not spray on rainy days, and if it rains within 24 hours after spraying, you need to spray again; do not spray in strong wind and sand to prevent losses; Spray to prevent burning leaves.

Abstract

The invention discloses a composite foliar fertilizer, and is characterized by comprising the following components in weight percent: 20-30% of potassium sulfate, 1-2% of ferrous sulfate, 1-5% of manganese sulfate, 1-2% of copper sulfate, 1-5% of zinc sulfate, 1-5% of surfactant, 1-5% of complexing agent and the balance water, wherein, the potassium sulfate compounds with tiny fertilizer and the surfactant to manufacture the foliar fertilizer which has nutrient substances needed for the growth of the plants. The compounded foliar fertilizer has strong moistening capacity, and is absorbed by plants through foliar surface cuticula or non-keratinized guard cells and pores when being sprayed on the foliar surfaces of plants, thus improving the use ratio of fertilizer efficiency and the supplement of the tiny fertilizer, and being a fertilizing method with low cost, quick effect and simple method.

Description

Technical field [0001] The invention relates to the technical field of chemical fertilizers, in particular to a compound foliage 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 re...
