Conventional fertilizer application is considerably better than in silica alumina ratio effect.
3 2014-2016 of table takes out flower bud phase different disposal banana growing way and yield
The quality of Banana Growth situation will directly influence the superiority and inferiority of the height and quality of banana production.Pumping flower bud phase growing way is fixed within 3 years
Position investigation shows (table 3) that test 1-7 processing banana plant height, stem girth, the number of blade, pumping flower bud rate, yield are all remarkably higher than conventional place
Reason, and test 7 treatment effect slightly below test 1-6.
Influence of 4 different fertilizer of table to banana quality
As shown in Table 4, mature banana Vitamin C content that monosodium glutamate waste liquid humic acid suspension fertilizer of the present invention harvests, solvable is applied
Property sugared content, soluble solid content all improve, quality is better than conventional fertilizer application.It is prepared by especially application embodiment 1
The banana quality of obtained monosodium glutamate waste liquid humic acid suspension fertilizer is more excellent；What is applied in test 7 is not add tea stalk powder,
Remaining ingredient and the preparation method is the same as that of Example 1 fertilizer obtained, Vitamin C content, soluble sugar content, soluble solid contain
Amount all slightly below tests 1-6 group.The addition of tea stalk powder can promote the formation of soil aggregate structure, improve soil to a certain extent
The water retention property and gas permeability of earth, improve the function of soil, further promote effect of fertilizer performance, provide fruit yield and
Character.
The foregoing is merely preferable case study on implementation of the invention, all equivalent changes done according to scope of the present invention patent
With modification, it is all covered by the present invention.
