Embodiment Construction
[0009] Take by weight 25% of potassium citrate, 1% of ferrous sulfate, 4% of manganese sulfate, 1% of copper sulfate, 5% of ammonium molybdate, 1% of surfactant, 2% of complexing agent, and the rest are water. Stir at high 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.

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...
