Method of administration are as follows: 7 days after vegetable permanent planting, fertilizer is diluted into 200 times of progress trickle irrigation applications, every 15 days trickle irrigations one Secondary, each irrigation quantity is 5m3/ mu.Control group and test group are according to said method applied fertilizer, to each processing before first time picks Each repetition take 10 plant, carry out plant height, single-strain fresh weight, vitamin C, soluble sugar and nitrate content (with nitre state Nitrogen content meter) measurement, the results are shown in Table 4.All plant samples are acquired in morning 9:00 on the same day.
4 three-coloured amaranth growing state of table and yield application form
By upper table result it is found that plant height, single-strain fresh weight, the yield of the three-coloured amaranth of test group 1-7 processing are above control group, and nitric acid Salt content is substantially reduced compared with control group, and quality is constant.Test group increases by 12.1% or more compared with the plant height that control group is handled, single plant Fresh weight increases by 17.6% or more, and yield increases by 18.7% or more, and nitrate content reduces by 26% or more.
10 manure trial of example
Fertilizer is suspended to leaf vegetables growth and the influence of yield, in Fujian Academy of Agricultural Sciences's soil in order to verify gained liquid The manure trial of gained liquid suspension fertilizer is carried out in the village Jian Tian near fertilizer research institute.
Examination is three-coloured amaranth for vegetable variety；Examination is grey yellow soil for soil types.
This manure trial is field plot trial, each plot area 10m2。
Seven processing of test setting:
Test group 1-5: example 1-5 liquid suspension fertilizer produced is applied respectively.
Control group A: EDTA-Cu, EDTA-Zn, EDTA-Fe, EDTA-Mn used in example 1 are replaced with into equivalent five respectively Brochanite, white vitriol, ferrous sulfate heptahydrate, manganese sulfate monohydrate are administered with gained liquid suspension fertilizer.
Control group B: sand punt-pole glue used in embodiment 1 is replaced with into equivalent xanthan gum, is applied with gained liquid suspension fertilizer With.
Method of administration are as follows: 7 days after vegetable permanent planting, fertilizer is diluted into 200 times of progress trickle irrigation applications, every 15 days trickle irrigations one Secondary, each irrigation quantity is 5m3/ mu.
Control group and test group are according to said method applied fertilizer, and take 10 to each repetition of each processing before first time picks A plant carries out the survey of plant height, single-strain fresh weight, vitamin C, soluble sugar and nitrate content (in terms of nitrate nitrogen content) It is fixed, it the results are shown in Table 5.All plant samples are acquired in morning 9:00 on the same day.
5 three-coloured amaranth growing state of table and yield application form
By upper table result it is found that plant height, single-strain fresh weight, the yield of the three-coloured amaranth of test group 1-5 processing are above control group, and nitric acid Salt content is substantially reduced compared with control group, and quality is constant.Test group increases by 10.9% or more compared with the plant height that control group is handled, single plant Fresh weight increases by 16.2% or more, and yield increases by 19.2% or more, and nitrate content reduces by 24% or more.
The above results show that compared with common fertilizer, liquid suspension fertilizer of the present invention can improve plant height, the list of leaf vegetables Strain fresh weight and yield, while reducing nitrate content.
The foregoing is merely presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with Modification, is all covered by the present invention.
