Abstract

The invention discloses special long-acting slow-release fertilizer for durians. The long-acting slow-release fertilizer comprises, in parts by weight, 6-12 parts of iodine heptafluoride, 5-9 parts of vanadium chloride, 4-8 parts of calcium iodide, 6-11 parts of monocalcium phosphate, 12-20 parts of IVE (isobutyl vinyl ether), 3-7 parts of DOTP (dioctyl terephthalate), 2-8 parts of bamboo juice, 1-5 parts of figwort roots, 3-8 parts of calcium tartrate, 3-5 parts of calcium bromide, 2-7 parts of cadmium nitrate, 6-8 parts of cathepsin, 8-14 parts of papain, 1-2 parts of glycine, 1-4 parts of proline and 2-4 parts of a slow release agent. The special long-acting slow-release fertilizer has the benefits that the special long-acting slow-release fertilizer for the durians can supply nutritional ingredients required by the durians for a long time, meanwhile, a bactericide and organic fertilizer are added, and the soil fertility is improved.

Description

A kind of durian Special long-acting slow release fertilizer

Technical field

The invention belongs to agricultural fertilizer field, be specifically related to a kind of durian Special long-acting slow release fertilizer.

Background technology

Durian, aiphyllium, Gao Keda 25 meters, scale is arranged at sprout top.The long 1.5-2 centimetre of stipule, blade Long Circle, the sometimes shape of falling ovum Long Circle, short gradually point or anxious gradually point, basal circular or blunt, it is bright that durian is sent out on two sides, above smooth, there is adhesion scale at the back side, lateral vein 12-12 couple, long 12-15 centimetre, wide 3-5 centimetre; The long 1.5-2.8 centimetre of petiole, cyme is elongated sagging, clusters on stem or on bough, and every sequence has colored 3-30 piece; Bud is spherical; Bennet by scale, long 2-4 centimetre.

Sustained-controll-release fertiliser refers to that fertilizer nutrient rate of release is slow in a broad sense, and release period is longer, can meet the fertilizer of plant growth need in the whole vegetative period of crop.But concerning slow-release fertilizer and Controlled Release Fertilizer, there is again its definition different separately in the narrow sense.Slow-release fertilizer is also known as controlled availability fertilizer, and mainly finger changes the speed of plant available nutrient into than common fertilizer fertilizer slowly after being manured into soil.Its rate of release, mode and time length can not control well, and the impact by fertilization mode and envrionment conditions is larger.Controlled Release Fertilizer release principle is that the nutrient in fertilizer is from the process of solid state into liquid state, the speed of its release and the rule of Crop nutrient match, time such Crop nutrient is many, just release is many, what just discharge time few lacks, and improves the utilization ratio of fertilizer greatly, so Controlled Release Fertilizer is more high in technological content than common fertilizer, there is the effect of Intelligent controlled release, so be also its intelligent fertilizer.

Summary of the invention

For the deficiencies in the prior art, the technical problem to be solved in the present invention is, provides a kind of durian Special long-acting slow release fertilizer, can supply crop desired nutritional composition for a long time, add microbial inoculum, fertilizer simultaneously, improve soil fertility.

For solving the deficiencies in the prior art, technical scheme of the present invention is, a kind of durian Special long-acting slow release fertilizer, and it is made up of following weight part:

Iodine heptafluoride 6 ~ 12 parts, vanadium chloride 5 ~ 9 parts, calcium iodide 4 ~ 8 parts, monocalcium phosphate 6 ~ 11 parts, IVE 12 ~ 20 parts, Di-2-ethylhexyl terephthalate 3 ~ 7 parts, bamboo juice 2 ~ 8 parts, radix scrophulariae 1 ~ 5 part, calcium tartrate 3 ~ 8 parts, Calcium Bromide 3 ~ 5 parts, cadmium nitrate 2 ~ 7 parts, kethepsin 6 ~ 8 parts, papoid 8 ~ 14 parts, glycine 1 ~ 2 part, proline(Pro) 1 ~ 4 part, sustained release dosage 2 ~ 4 parts.

The invention has the beneficial effects as follows that durian Special long-acting slow release fertilizer of the present invention can be supplied crop desired nutritional composition for a long time, add microbial inoculum, fertilizer simultaneously, improve soil fertility.
