Abstract
The invention discloses a water-soluble humic-acid-contained fertilizer specially for cherries, relating to the technical field of water-soluble fertilizers. The water-soluble humic-acid-contained fertilizer special for cherries is obtained by taking 3-10 parts of water-soluble humic acid, 35-60 parts of ammonium nitrate phosphate, 5-20 parts of water-soluble monoammonium phosphate, 25-55 parts of water-soluble potassium sulphate and 0.5-3 parts of EDTA (Ethylene Diamine Tetraacetic Acid) chelated trace elements through the steps of heating, fusing, spraying and prilling through a prilling tower, cooling and curing. The fertilizer specially for cherries has the advantages of good water solubility, balanced nutrition and capability of improving the soil nutrient condition, increasing the nutrient utilization ratio and the yield of the cherries and improving the quality of the cherries.
Description
Technical field
The present invention relates to the water soluble fertilizer technical field, particularly relate to special-purpose fertilizer of a kind of water-soluble cherry and working method thereof.
Background technology
Cherry is the Rosaceae, Prunus, cherry subgenus, the perennial woody crop.Cherry is " treasure in the fruit ", and the good reputation in " really first of spring " is arranged.Cherry fruit from blooming to plucking has only 2-3 month time, and vegetative period is very short, so the consumption of nutrient short-term is big, therefore, cherry has the advantages that to grow rapidly, need fertilizer to concentrate.
Fruit trees such as cherry need nitrogen maximum, and nitrogen can promote growth, makes treelet do sth. in advance moulding, and the veteran delay senility improves fruit quality, improve output.Nitrogen stress, the leaf growth is slow, and the tree bulk-growth is slow, and blade is little and thin, and light and performance reduce, and influence glucide and proteinic formation, and fruit drop is serious.Long-term nitrogen stress then causes fruit tree to utilize and is stored in the organic compounds containing nitrogen in limb and the root, thereby reduces the nitrogen content of tree body, and the performance root system is undeveloped, and resistance is poor.Phosphorus can promote bud differentiation, and fruit development nuclear species is ripe, improves fruit quality.Increasing the p application rate can also improve the root system receptivity, promotes new root growth, improves tree body resistance and disease resistance.Scarce phosphorus can influence intravital substance metabolism of tree and energy metabolism, and the rudiment of extension fruit is bloomed, and reduces germination rate, influences root system development and bud differentiation.The serious phosphorus that lacks, fruit quality descends.Potassium is a kind of important nutritive element that the fruit tree absorbed dose is only second to nitrogen, and in the tree body, potassium exists with ionic state; In substance metabolism, potassium can promote the conversion and the transportation of sugar, helps that out of date expands and ripe; Improve fruit quality and keeping quality, strengthen the anti-adversity ability of tree body.The conversion of potassium deficiency influence sugar causes fruit little, and leaf is little, and is painted bad, is prone to dehiscent fruit.During severe potassium deficiency, blade edge is prone to shrivelled, caducous.According to research, every production 1000Kg cherry fresh fruit needs absorbed nitrogen (N) 10.4Kg, phosphorus (P
2O
5) 1.4Kg, potassium (K
2O) 13.7Kg, nitrogen, phosphorus, potassium assimilation ratio are: 1:0.14:1.3.
Adopt common fertilizer concerning cherry, mainly to have following problem:
1, the common fertilizer life-time service can make soil become to harden, and soil fertility weakens, and the crumb structure of soil is destroyed serious, the havoc ecotope;
2, common fertilizer is used the fixing and loss that causes nutrient easily, and environment is polluted;
3, the common fertilizer nutrient element releasing rule can't match with the cherry law of nutritive absorption, and utilization rate of fertilizer is low;
4, 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, and causes the cherry quality to descend.
The arrival with the low-carbon economy epoch of popularizing along with industrialized agriculture; High-efficiency agriculture will significantly increase the demand of water soluble fertilizer; Therefore; 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 cherry output and quality just necessary.
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 being applied to special-purpose fertilizer of the cherry of water fertilising and working method thereof.
The present invention realizes through following technical scheme:
The water-soluble cherry that the present invention contains humic acids is special-purpose fertile, and the feed composition weight part is following:
