Special potassium fertilizer for kidney bean of green bean

Abstract

The invention relates to a special fertilizer for a kidney bean of green bean. The fertilizer comprises the following ingredients by weight (kilogram): 12 kg of nitrogen, 5.4 kg of phosphorus pentoxide, 20kg of potassium oxide, 10 kg of active calcium, 8 kg of amino acid, 1 kg of boron, 0.8 kg of zinc, 0.8 kg of manganese, 1.2 kg of molybdenum, 1.2 kg of iron, 1 kg of rooting agent, 1 kg of chitinand 1 kg of algin, wherein the precision of the ingredients is + / -10%. Because the fertilizer consists boron, zinc, manganese, molybdenum and iron as well as some special substances such as the rooting agent, the chitin and the algin that are favorable to the growth and development of crops, the prescription is scientific, the elements are balanceable, the technique is advanced; the potassium fertilizer, active calcium, boron, zinc, manganese, molybdenum and iron are particularly prepared with pertinence according to the requirements of crops so as to greatly improve the quality of products.Compared with the common potassium fertilizer, the special potassium fertilizer can increase the yield, improve the quality and prolong the fruiting period through the experiments at a base of kidneybean of green bean.

Description

technical field [0001] The invention relates to a high-efficiency special fertilizer for vegetables, specifically a special fertilizer for beans and kidney beans, which is composed of nitrogen, phosphorus and potassium as main elements and added trace elements (boron, zinc, manganese, molybdenum, iron) and active calcium. potash fertilizer. Background technique [0002] In recent years, the population of large and medium-sized cities has been increasing, the old vegetable fields have gradually decreased, and the new vegetable fields have continued to expand. The types and levels of fertilization of beans and kidney beans have also undergone great changes. In some areas, the application of organic fertilizers has decreased, while the amount of chemical fertilizers has decreased Increasing, and the variety is single, heavy nitrogen fertilizer light phosphorus fertilizer, potash fertilizer, and the utilization rate of chemical fertilizer is low. These factors lead to the decli...

[0002] In recent years, the population of large and medium-sized cities has been increasing, the old vegetable fields have gradually decreased, and the new vegetable fields have continued to expand. The types and levels of fertilization of beans and kidney beans have also undergone great changes. In some areas, the application of organic fertilizers has decreased, while the amount of chemical fertilizers has decreased Increasingly, and the variety is single, heavy nitrogen fertilizer light phosphorus fertilizer, potash fertilizer, low utilization rate of chemical fertilizers, etc.

These factors lead to the decline of soil organic matter, the deterioration of soil buffering capacity, and the lack of sufficient nutrients for the bean and kidney bean crops, resulting in a decrease in the yield and quality of the bean and kidney bean
