Special compound fertilizer for seedling raising of Acacia mangium*A.auriculiformis Cunn.ex Bench

Abstract

The invention discloses a special compound fertilizer for seedling raising of Acacia mangium*A.auriculiformis Cunn.ex Bench, which is prepared by crushing and mixing macro element fertilizer, trace element fertilizer, plant growth regulator and the like according to a certain ratio. The special compound fertilizer is prepared from the following effective ingredients (including nitrogen, phosphorus and potassium) and trace elements (effective content) in percentage by weight: 21.2-51.9% of nitrogen, 22.3-37.1% of phosphorus pentoxide, 10.3-33.1% of potassium oxide, 2.02-3.33% of calcium, 0.96-1.53% of magnesium, 0.10-0.55% of iron, 0.02-0.14% of manganese, 0.01-0.05% of zinc, 0.005-0.06% of copper, 0.001-0.05% of boron and 0.001-0.01% of molybdenum. By providing the targeted special compound fertilizer, the invention effectively promotes the growth of artificial Acacia forest.

Description

technical field [0001] The invention relates to the field of compound fertilizers in forestry production, in particular to a special fertilizer for acacia. Background technique [0002] The invention belongs to a compound fertilizer, in particular to a large amount of elements such as N, P, K, Ca, Mg, S, and elements such as Mn, Mo, Zn, Cu, Fe, B, etc. special fertilizer. [0003] Acacia mangium×A. auriculiformis Cunn.ex Bench is a plant of Mimosa subfamily and genus Acacia. It is a combination of Acacia mangium and A. auriformis Cunn. ex Bench), which has the dual advantages of Acacia Mazhan and Acacia Daye (abbreviated as Acacia Mada). Acacia Mada has obvious heterosis, with yellow pollen (similar to the male parent) and white filaments (similar to the female parent); fast-growing, strong adaptability, large biomass, strong water storage and nitrogen fixation ability, genetic gain of 18%, and annual growth of up to 100%. 22m3 / ha; resistant to short-term low temperature ...

Problems solved by technology

The nutrient utilization efficiency of each tree species is P or Mg>Ca>K>N; Liu Shui'e et al. (2002) designed 5 levels of N, P, and K 3 nutrient ratio ratio experiments using hydroponic methods, and analyzed the effect of different ratios on Acacia mazhansis seedlings. (2004) explored the effects of fertilization on the growth and stem shape of Acacia thick viburnum, and the test results showed that different fertilization treatments had very significant effects on tree height, diameter at breast height, and volume growth per plant; Wang Linghui et al. (2005 ) Although the research on the influence of basal fertilizer on the growth of Acacia thick pods and the content of nutrient elements in the leaves has been done, it only stays on the leaves, and has not yet been systematically studied on the whole tree

[0005] At present, there is no compound fertilizer product for Acacia artificial forest trees on the market, and there is still a lack of special fertilizers with strong practicability for specific trees in different regions.
