Abstract

The invention discloses a foliar fertilizer promoting alfalfa seedling growth in acidic soil. The foliar fertilizer is composed by mixing a root growth solution, a mineral nutrient solution, an organic nutrient solution and clear water. Each liter of the foliar fertilizer contains 1-2ml of the root growth solution, 1-2ml of a plant nutrient solution, 3-5ml of the organic nutrient solution, and the balance clear water. The foliar fertilizer of the invention can effectively promote the growth and development of alfalfa seedling roots in strongly acidic soil, protect root activity and cell structures, relieve alfalfa seedling poisoning, and promote alfalfa growth. In a soil environment with pH of 4.5, the foliar fertilizer of the invention is adopted to treat alfalfa which has an average plant height of 5cm. The foliar fertilizer is sprayed once every 10 days and 2 times in total. 1-2L/m<2> of the fertilizer is sprayed every time. After 30 days of treatment, the alfalfa root biomass is increased by 1.5-1.8 times compared with a control one (only spraying water), and the aboveground biomass is increased by 1.0-1.4 times compared with the control one.

Description

technical field [0001] The invention relates to a plant foliar fertilizer in the field of agricultural technology, in particular to a foliar fertilizer for improving the growth of alfalfa seedlings in acidic soil. Background technique [0002] The soil in the red soil area in southern my country generally presents strong acidity (pH<5.0), which inhibits the growth and development of the root system of alfalfa, passivates the root tips, shortens the root hairs, and reduces the nutrient absorption function, which in turn inhibits the growth of alfalfa, resulting in low alfalfa plants, Slow growth and very low yield have seriously restricted the cultivation of alfalfa in southern red loam areas. [0003] At present, there are relatively few research reports on promoting the growth of alfalfa in acidic soil, and there are no effective technical measures. After searching the literature of the prior art, it was found that Guo Yanjun and Huang Jianguo (2006) reported that adding...
