Problems solved by technology

[0002] In the traditional hemp production, a single fertilizer is applied all the year round, such as urea as nitrogen fertilizer or diammonium phosphate compounded with nitrogen and phosphorus. Due to unscientific fertilization, not only the yield and quality of hemp are low, but also the fertilizer utilization rate is low, and the production cost increases. The economic benefits of farmers planting hemp are not ideal

Embodiment

[0007] Embodiment: During the production and preparation of hemp blending special fertilizer, the following weight components are taken by each combination unit: 260 kilograms of urea, 200 kilograms of potassium sulfate, 50 kilograms of diammonium phosphate, 190 kilograms of superphosphate, 100 kilograms of calcium magnesium phosphorus powder kg, 200 kg of ammonium chloride, 1000 kg in total, after blending with a blender, this special fertilizer is obtained, wherein the total nutrient content of nitrogen, phosphorus and potassium reaches 35%, and the ratio of nitrogen, phosphorus and potassium is 18:7:10 .

[0008] Test results: Under the same conditions, the application of 20 kg of the special fertilizer mixed with hemp per mu was compared with the application of 30 kg of diammonium phosphate per mu in the contrast field. The yield is 13.5% higher, the seed yield is 10% higher, the hemp fiber strength is increased by 10%, and the effect of increasing yield and improving prod...

Abstract

A special blending fertilizer for China-hemp belongs to a chemical fertilizer and comprises the following components in parts by weight: 2.5-2.7 parts of urea, 1.9-2.1 parts of potassium sulfate, 0.4-0.6 part of diammonium phosphate, 1.8-2.0 parts of calcium superphosphate, 0.9-1.1 parts of calcium, magnesium, phosphorus powder and 1.9-2.1 parts of ammonium chloride. The fertilizer is novel and reasonable in formula component, comprehensive in fertilizing value, good in physical properties, high in fertilizing value utilization ratio and lower in fertilization cost, and can improve the China-hemp resistance and yield.

Description

technical field [0001] The invention belongs to chemical fertilizers, and mainly relates to a special chemical fertilizer for hemp. Background technique [0002] In the traditional hemp production, a single fertilizer is applied all the year round, such as urea as nitrogen fertilizer or diammonium phosphate compounded with nitrogen and phosphorus. Due to unscientific fertilization, not only the yield and quality of hemp are low, but also the fertilizer utilization rate is low, and the production cost increases. The economic benefits of farmers planting hemp are not ideal. In recent years, with the improvement of the level of science and technology, agricultural science and technology workers have conducted in-depth research on the law of hemp growth and fertilization techniques, so it is imminent to provide a special fertilizer suitable for the growth of hemp. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the ...
