Abstract
The invention discloses a water-soluble humic acid grape special fertilizer and relates to the technical field of water-soluble fertilizers. The special fertilizer comprises the following raw materials in parts by weight: 3-10 parts of water-soluble humic acid, 20-70 parts of urea, 25-60 parts of water-soluble monoammonium phosphate, 20-50 parts of water-soluble potassium sulfate and 0.5-1.5 parts of EDTA chelate trace element; and the spray granulation technology of a granulation tower is adopted for granulation to obtain the water-soluble humic acid grape special fertilizer. Compared with the prior art, the special fertilizer disclosed by the invention has the advantages of high nutrient content, comprehensive nutrition and high utilization rate of fertilizers, and can obviously improve the output and quality of grape.
Description
Technical field
The present invention relates to the water soluble fertilizer technical field, particularly relate to a kind of water-soluble grape special fertilizer.
Background technology
Grape is the perennial vine crop of Vitaceae Vitis, and in global fruit was produced, it is the first that the output of grape and cultivated area occupy always.Grape is not only delicious good to eat, and nutritive value is very high, and sugar degree is main up to 10%-30% with glucose in the sophisticated berry, can directly be absorbed by human body, also contains mineral calcium, potassium, phosphorus, iron and multivitamin, and multiple essential amino acid.
Thank to researchs such as Jianchang and show that the Daze Mount vintage that is grown on the brunisolic soil is 18t/hm
2, per hectare nutrition absorption amount is nitrogen (N) 138kg, phosphorus (P
2O
5) 105 kg, potassium (K
2O) 225 kg, its assimilation ratio are 1:0.8:1.6.Grape has the trend above the potassium absorbed dose to the absorbed dose of calcium in the data of Fregoni (1984).Therefore, grape high-yield is calcium＞potassium＞nitrogen＞phosphorus to the demand of nutrition.
Because grape variety is various, need fertile performance different, add that the requirement of yield per unit is different, grape science fertilizer practice requires reasonably to confirm dose, according to the victory researchs such as (2001) of horse, 1000 m
2The vineyard produces 1500 kg grapes, absorbed nitrogen (N) 8.84 ㎏, phosphorus (P
2O
5) 4.15 ㎏, potassium (K
2O) 10.23 ㎏, the ratio of absorbed nitrogen phosphorus potassium is 1:0.47:1.16.Yang Zhiyuan (2008) thinks; It is leading indicator with the growth potential that grape variety needs fertile characteristic; The prosperous kind of growing way is Shaoshi fertilizer suitably, and growing way kind on the weak side then can suitable many fertilises, and the applicating ratio of nitrogen phosphorus potassium is with 1:0.8 ~ 1:1 ~ 1.2 (the moderate-yield 1500kg/667 m that is advisable
2).
At present, mainly there are following three problems in common fertilizer concerning grape:
1, the common fertilizer life-time service can make soil become to harden, and the crumb structure of soil is destroyed serious, and the grape quality obviously descends, and the more important thing is the havoc ecotope.
2, the common fertilizer nutrient element releasing rule can't match with the grape law of nutritive absorption, and utilization rate of fertilizer is low.
3, orchard worker's fertilising is main with the experience fertilising often, and cost is higher, and causes Soil structure and environment to be damaged, and the crop anti-adversity ability descends.
Develop rapidly for adapting to current water-saving agriculture, exploitation meets nuisanceless production requirement, reach improve the soil, promote fertilizer efficiency, promote growth, degeneration-resistant and to improve the high level of water soluble fertilizer of crop yield and quality just necessary.The applicant combines the regulation of fertilizer requirement and the characteristics of grape simultaneously through surveying the soil prescription, has researched and developed a kind of fulvo acid grape special fertilizer, has proposed a new thinking for addressing the above problem.
Summary of the invention
To the deficiency of prior art, the object of the present invention is to provide a kind of good water solubility, green non-pollution, utilization rate of fertilizer high, improve the soil, culture fertility and can be applied to grape special fertilizer and working method thereof with the water fertilising.
