Nitrogen-potassium mixed fertilizer

Abstract

The invention relates to a nitrogen-potassium mixed fertilizer, which comprises the following effective nutrients in part by weight: 10%-20% of nitrogen, 15%-25% of potassium, 5%-15% of active calcium, 1%-3% of amino acid, 0.3%-1% of soil activating agent, 0.1%-1% of expansion agent and 0.1%-3% of complexing agent. By using the nitrogen-potassium mixed fertilizer, not only can the quality of a fruit be improved, are the cold resistance capability and the drought resistance capability of a plant body enhanced, and are the contents of sugar and vitamin C of the fruit improved; but also the yield of a crop can be effectively improved, the self quality of a plant is improved better, and the effects of growth facilitation and quick growth can be achieved; and simultaneously, on the aspects of improving a soil environment, strengthening fertility making capability and promoting soil microbial metabolism, the nitrogen-potassium mixed fertilizer has stronger advantages.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to a nitrogen-potassium mixed fertilizer. Background technique [0002] Nitrogen and potassium fertilizers play a very important role in the growth of crops. When nitrogen and potassium fertilizers are lacking, it is easy to cause crop leaves to scorch and necrosis, slow growth, short plants, thin and small leaves, green and yellow leaves, and unfulfilled grains , drought resistance, poor lodging resistance, etc., while the traditional nitrogen and potassium fertilizers have a single fertilizer and cannot meet the needs of crop growth, and the long-term use of chemical fertilizers such as nitrogen and potassium fertilizers will easily lead to soil compaction and soil environment. Deterioration will bring immeasurable losses to agricultural growth. SUMMARY OF THE INVENTION [0003] In order to solve the problem of single function of traditional nitrogen fertilizer and potassium fertil...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem of single function of traditional nitrogen fertilizer and potassium fertilizer, the present invention provides a nitrogen-potassium mixed fertilizer, which can not only improve fruit quality, enhance plant cold resistance and drought resistance, increase fruit sugar and vitamin C content, Moreover, it can effectively increase the yield of crops, improve the quality of the plants themselves, and can produce growth and growth effects. At the same time, it has strong advantages in improving the soil environment, strengthening the ability to make fertilizer, and promoting the metabolism of soil microorganisms.
