Description
Technical field
The present invention relates to a kind of capsicum special-purpose control-release fertilizer, particularly use, have capsicum special-purpose control-release fertilizer of control root disease and preparation method thereof, belong to release and release control fertilizer production and applied technical field at facility soil.
Background technology
Capsicum is a kind of crop of easy infection soil-borne disease, and in recent years, booth, greenhouse pepper planting area constantly increase; Multiple crop index improves, and the phenomenon of blindly applying fertilizer is serious, causes soil nutrient unbalance; Capsicum root rot, bacterial wilt, soil-borne diseases such as root knot nematode disease take place serious.And these disease majorities infect in seedling stage and take place.Medication again when common prevention and treatment method is morbidity, but late.
Chinese patent file CN101234928A (200810014188.X) discloses a kind of fertile method through composite production capsicum special-purpose control-release fertilizer of serial controlled release of utilizing sulfur and resin coated material produce; Although discharging, this controlled release fertilizer nutrient has and chili growth and the synchronous effect of nutrition absorption; But its weak point is: the one, and the nutrient proportioning is that the nutrition absorption that is directed against capsicum designs, and does not consider the difference of soil nutrient; Secondly, do not possess the effect of the early stage root disease of control capsicum.
Summary of the invention
To the deficiency of prior art, the present invention provides a kind of greenhouse pepper special-purpose control-release fertilizer of preventing and treating root disease and preparation method thereof.The present invention provides the application method of said capsicum special-purpose control-release fertilizer.
Summary of the invention
The present invention utilizes controlled release fertilizer to work in coordination with granular pesticide; Carry out existing coating controlled-release fertilizer and agricultural chemicals accurately composite; Make nutrient release and proportioning can be fit to the nutrient situation of facility soil and the absorption requirement of capsicum, add control medicament simultaneously to the capsicum root diseases.The greenhouse pepper special-purpose control-release fertilizer that the present invention prevents and treats root disease has applied once, and double effects saves labor, and has beat all good result through evidence.
Detailed Description Of The Invention
Technical scheme of the present invention is following:
The greenhouse pepper special-purpose control-release fertilizer of control root disease, it is following that raw material is formed mass parts:
Sulphur adds 150～200 parts of high molecular polymer coated carbamides,
150～200 parts of the double-deck coated carbamides of thermoplastic and thermosetting,
80～130 parts of urea undercoat modified epoxy resin integument diammonium phosphate,
130～180 parts in urea undercoat modified epoxy resin integument saltpetre,

Preferably, thiophanate methyl preparation, Avrmectin preparation, zinc manganese ethylenebisdithiocarbamate preparation particle diameter are 3～4 millimeters.
According to the present invention; The preparation method of the greenhouse pepper special-purpose control-release fertilizer of said control root disease is: above-mentioned each raw material is put into stirrer together in the ratio in the prescription stirred 5～10 minutes; Abundant mixing, with the fertilizer that mixes send into metering, wrapping machine measures, packs.
According to the present invention, the application of said capsicum special-purpose control-release fertilizer is used for the facility vegetable plot, every mu of consumption 120-180 kilogram, and whole bottoms that once apply planting furrow before capsicum is transplanted are with the capsicum rice shoot of planting after the part mixing with soil.Be used to prevent and treat the capsicum root disease and pest, and satisfy the needs of each growth phase of capsicum, improve yield of hot pepper nitrogen, phosphorus, potassium.
Excellent results of the present invention is following:
1. the nutrient proportioning is fit to the greenhouse pepper soil nutrient status
Greenhouse pepper is because profitable, and it is many that the peasant drops into fertilizer, and soil has more nutrient accumulation.It is not enough that but the vegetable grower understands capsicum fertilising knowledge, and the phenomenon of blindly applying fertilizer is serious, causes soil nutrient uneven, influences normal, the healthy growth of capsicum.The greenhouse pepper control released fertilizer special that the present invention prevents and treats root disease is to form according to the nutrition absorption characteristic of greenhouse pepper soil nutrient characteristics, capsicum and the accurate configuration of nutrient of the fertile raw material of controlled release, can satisfy greenhouse pepper high yield needs.
2. nutrient discharges and to meet capsicum and absorb the whole growing that requires capsicum, and is big to nitrogen, potassium requirement, needs phosphorus less.In the seedling phase, nitrogen, phosphate fertilizer all have remarkably influenced to the growth of seedling and the formation of flower, should suitably supply with.But nitrogen fertilizer amount can not be too much, prevents to cause plant excessive growth, and postponement is yielded positive results.In the period that be nitrogen, phosphorus the best fruiting period, the potassium demand is maximum, its quantity accounts for 57%, 61% and 69% of each self-absorption total amount respectively.Capsicum control released fertilizer special of the present invention utilizes fertile composite the forming of nitrogen, phosphorus, potassium controlled release of the different release periods of different coating controlled-release fertilizers just according to this absorbing rule, can satisfy the special requirement of the different growth phases of capsicum to three elements.
3. well the pepper planting rotation of crops at present is difficult for protection effect, and the protectiveness cultivation increases, and soil-borne disease takes place serious day by day.Seedling stage particularly, be completely cured and seedling is had a low resistance the easy infection multiple diseases owing to transplant.Utilize medicine liquid irrigation root or sprinkling when the ordinary method in the production is morbidity, but caused certain harm.Medicament in this special-purpose fertilizer is selected for use good medicaments of multiple diseases control effect such as capsicum root rot, bacterial wilt, root knot nematode diseases, when transplanting, applies main root district with fertilizer, is completely cured, endangers seedling and have good action preventing the germ intrusion.
4. applied once, double effects, the capsicum that saves labor utilizes common fertilizer repeatedly to use in the time of infertility, a disease takes place then will irritate root 2～3 times, and recruitment is many, and labour intensity is big.The capsicum fertilising of fertile per season of this special use once and has preventive and therapeutic effect to sprout term disease, has reduced the operation number of times, greatly reduces peasant's labour intensity, has practiced thrift the recruitment cost, has improved economic benefit.
