Problems solved by technology

The survey shows that the following problems exist in the management of weak gluten wheat fertilizers in our province: (1) The blindness and randomness of fertilization are large, the effect of fertilizer input is poor, and the utilization rate of fertilizer is low
(2) The amount of fertilizer is low, and the proportion of nutrients is not coordinated. It is manifested as heavy nitrogen and phosphorus fertilizer, light potassium and medium and trace element fertilizer, which aggravates the imbalance of soil nutrients.
(3) There are few special formula fertilizers for weak gluten wheat, and the industrialization of fertilization starts slowly

Abstract

The invention discloses a special fertilizer for weak gluten wheat, comprising the following effective elements based on pure nutrients by with weight percent: 20.0-24.0 percent of nitrogen, 8.0-12.0 percent of phosphorus pentoxide, 10.0-14.0 percent of potassium oxide, 3.5-5.5 percent of calcium oxide, 1.0-4.0 percent of sulfur and 0.5-1.0 percent of zinc. The special fertilizer for the weak gluten wheat has complete nutrients, reasonable nutrient proportion according with to a nutrient absorbing rule of the weak gluten wheat and high utilization of the fertilizer, thereby obviously promoting the growth of the weak gluten wheat, improving the yield of grains, increasing the economical benefit, improving the quality of the weak gluten wheat and simultaneously reducing the unbeneficial influence on the environment caused by the improper use of nitrogenous fertilizera.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special formula fertilizer for weak gluten wheat. Background technique [0002] Wheat has a long history of planting in Anhui Province. The annual sowing area of ​​wheat in the province is about 2 million hectares, accounting for about 45% of the province's arable land area, accounting for 34% of the total annual grain sowing area, and its total output accounts for 32%, higher than the national average, is the second largest food crop after rice. In the wheat planting divisions of our province, the north of the Huaihe River is mainly planted with medium-strong gluten wheat, and the south of the Huaihe River is mainly planted with weak-gluten wheat. In recent years, the market demand for high-quality special weak-gluten wheat is increasing. Although breeders have bred some excellent weak-gluten wheat varieties, which have laid a good germplasm foundation for the...
