Problems solved by technology

It can be seen that unreasonable fertilization can easily lead to low fertilization efficiency, poor fertilizer utilization rate, and even the situation of increasing production but not increasing income, which not only affects the yield of sunflowers but also seriously affects the quality of sunflower products

Abstract

The invention provides a special fertilizer for sunflowers as well as a preparation method and an application method of the special fertilizer, and belongs to the technical field of fertilizers. The special fertilizer for the sunflowers comprises 475-485 parts of a nitrogen fertilizer, 160-170 parts of a phosphate fertilizer, 233-235 parts of a potassium fertilizer, 8-15 parts of a zinc fertilizer, 3-10 parts of a boron fertilizer, 0.17-0.18 part of a urease inhibitor and 100-105 parts of a biological organic fertilizer. The special fertilizer is reasonable in formula, all the components have a synergistic effect, the sunflower yield, the thousand seed weight and the protein content can be remarkably improved, and economic benefits are improved. Experimental results show that the special fertilizer can significantly improve the thousand seed weight and the protein content of sunflower seeds and increase the yield. Compared with farmers' habitual fertilization, excessive input of nitrogen and phosphorus nutrients is reduced, the ratio and dosage of nitrogen, phosphorus and potassium fertilizers are more reasonable, the yield is increased by 186.0-821.9 kg / hm<2>, and the economic benefit is increased by 842.0-5211.8 yuan / hm<2>.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special fertilizer for sunflowers, a preparation method and an application method thereof. Background technique [0002] Sunflower is the fourth largest oil crop in my country. In 2020, the national sowing area will be 1.2 million hectares, and the output will be about 3 million tons. Among sunflower seeds, the oil content of oil species is 40% to 56%, which is the oil crop with the highest oil content, and the oil is of good quality, not only edible, but also a good raw material for tanning, printing, coating and other fields. Therefore, my country's demand for sunflowers continues to increase. [0003] Fertilization is the material basis for increasing sunflower production, but because growers are not clear about the characteristics of sunflower nutrient absorption, unbalanced fertilization and excessive fertilization are more serious. Among them, the imbalan...
