Abstract
The invention discloses a special sulfur-resin double-membrane humic-acid controlled release fertilizer suitable for culturing garlic with a mulching film. The fertilizer is characterized by being prepared from the following ingredients by mass percent: 130%-165% of resin-coated urea, 135%-150% of sulfur-coated urea, 120%-170% of diammonium phosphate, 290%-380% of potassium sulphate, 220%-240% of humic-acid controlled release compound fertilizers and 10%-15% of zinc sulfate. Compared with the prior art, the special sulfur-resin double-membrane humic-acid controlled release fertilizer for culturing the garlic is produced in a compounded manner by utilizing the nutrient releasing characteristic of a sulfur-coated and resin-coated fertilizer and the slow release synergy effect of humic acid on nutrients according to the nutrient absorption principle of the garlic, and a certain amount of medium and trace elements are compounded in the fertilizer, so that the interdependence between release and control of nutrients is achieved, and good fertilizing and absorbing effects are ensured.
Description
Technical field
The present invention relates to a kind of slow/controlled release fertilizer technology field that belongs to, specifically is a kind of two film humic acids slow-release or control-release fertilizers of the special-purpose sulfur and resin of film-mulching cultivation garlic that are suitable for.
Background technology
Garlic is a Liliaceae allium biennial herb plant, and special sharp flavor is arranged, and is requisite seasonings and the important export vegetables of earning foreign exchange in the daily life.
The Shandong garlic mainly concentrates on by the end of September to the early October sowing, and the membrane covering open country is survived the winter, and gather in the crops to early June next year by the end of May.Common composite fertilizer fertilizer efficiency is fast, and when base fertilizer applied, the garlic seedling was little, absorbs the fertilizer ability, and fertilizer is prone to the loss loss, is difficult to satisfy the nutrient demand of garlic growing period, and temperature and ground temperature are lower in the winter time.Therefore when the film-mulching cultivation garlic, provide a kind of and can increase production, can improve again the long-acting slow-releasing and controlled-releasing of quality fertile very necessary.
Be main to use readily avaiable fertilizer during current garlic produces; The membrane covering of extensively adopting has strengthened the difficulty of topdressing again; Part garlic farmers are for the saving of labor; At seeding time with nitrogenous fertilizer 60%～80%, all the disposable base of phosphorus potash fertilizer is executed (all the other nitrogenous fertilizer spring in next year topdress use), but this and do not meet the nutrition absorption characteristic of garlic; Readily avaiable fertilizer decomposes soon in addition, difficulty is made this traditional fertilizing method very easily cause available nutrient a large amount of losses in the winter time by soil fixing, thereby reduces utilization rate of fertilizer.
The controlled release fertilizer nutrient discharges steadily, can artificially control its release period (2-3) according to the crop nutrition content absorption characteristics.In common controlled release fertilizer, mix the controlled release Bulk Blending Fertilizer that the quick-acting chemical fertilizer of part are processed, controlled release is fertile to be supplied the fertile persistent general feature except that possessing, and has also solved the low excessively problem of traditional controlled release nutrient release amount in fertile early stage.In addition, the minimizing of coating quantity has also reduced cost, more is prone to accepted by garlic farmers.
Summary of the invention
For addressing the above problem; The present invention provides a kind of two film humic acids slow-release or control-release fertilizers of the special-purpose sulfur and resin of film-mulching cultivation garlic that are suitable for, and the present invention utilizes the Nutrient Release of sulphur, the two membrane envelope fertilizer of resin, and humic acids is to the sustained-release synergistic effect of nutrient; Law of nutritive absorption according to garlic carries out the two film humic acids slow-release or control-release fertilizers of the special-purpose sulfur and resin of composite production garlic simultaneously; And composite a certain amount of middle trace element, the slow control of nutrient is Ji mutually, guarantees good fertilising and assimilation effect.
For achieving the above object, the present invention adopts following technical scheme:
A kind of two film humic acids slow-release or control-release fertilizers of the special-purpose sulfur and resin of film-mulching cultivation garlic that are suitable for, said fertilizer components and weight proportion are following:

Zinc sulfate adopts commercially available agricultural Zinc Sulphate Heptahydrate crystal, and zinc content is 21～22%, sulphur content >=10%;
The mass percentage content of nitrogen, Vanadium Pentoxide in FLAKES, potassium oxide is in the humic acid slow release composite fertilizer: 14%～16%, 7～9%, 16～18%, and humic acids content >=10%.
Above-mentioned humic acid slow release composite fertilizer, the mass percentage content of nitrogen, Vanadium Pentoxide in FLAKES, potassium oxide is respectively 15%, 8%, 17%.
Said component raw material particle diameter is 2-4mm.
Excellent results of the present invention is following:
1. quick-acting, slow, long-acting combining; Satisfy the garlic nutrient demand in vegetative period; Especially satisfied the nutrient demand of garlic under the shed cultivation condition: diammonium phosphate, vitriolate of tartar can provide the quick-acting npk nutrients of garlic early growth; Sulphur and resin coated urea provide the nitrogen nutrient of different release periods, and the nutrient demand of garlic whole growth phase is satisfied in the npk nutrient that humic acid slow release the is fertile release of releiving.
2. nutrient reasonable ratio is fit to the nutrient uptake feature of garlic, and composite a certain amount of in trace element (sulphur, zinc); And contain the synergy nutrient, stimulate plant growth and improve the humic acids composition of quality; The slow control of nutrient is Ji mutually, improves specific absorption and plant recovery of nutrient, improves quality of agricultural product.
3. can effectively promote plant growth, can play the effect of improving the soil of preserve moisture and fertility again, production-increasing function is remarkable, and raising the output can reach about 10%.
4. significantly improve soluble proteins and VC content in the garlic, improve garlic quality and mouthfeel.
Below in conjunction with embodiment the present invention is further specified.
