Abstract
The invention discloses a controlled release fertilizer for cucumber and preparing method thereof. The fertilizer is prepared from, by weight, 20-30 parts of potassium dihydrogen phosphate, 10-15 parts of sulfate, 20-30 parts of urea, 25-35 parts of polylactic acid, 15-25 parts of polyvinyl alcohol. The method comprises making the compound fertilizer by pelleting after mixing potassium dihydrogen phosphate, sulfate and urea.The method controls the element content of nitrogen, phosphorus, potassium in compound fertilizer and the particle size of compound fertilizer, thus to improve the air permeability of fertilizer. The degradable period of degradable materials after mixing polylactic acid with polyvinyl is close to the growth cycle of cucumber, so that the method also comprises packaging the fertilizer according to the strict ratio of degradable materials and compound fertilizer. And the controlled release fertilizer can satisfy the nutrition which cucumber requires when growing and guarantee the long-term average release of nitrogen, phosphorus, potassium,which improve the quality and output of cucumber.
Description
Technical field
The present invention relates to fertilizer processing technique field is and in particular to a kind of Fructus Cucumidis sativi special-purpose control-release fertilizer and preparation method thereof.
Background technology
Fructus Cucumidis sativi Cucurbitaceae is annual to overgrow or climbs up by holding on to herbaceous plant.Stem, branch elongation, have rib ditch, by white rough bristle.Volume
Must be thin.Petiole is slightly coarse, has rough bristle；Blade width ovate is heart-shaped, film quality, and sliver triangle is with teeth.Hermaphroditism.Male flower: often
Several in the life of axil cluster；Bennet is very thin, by micro- pubescence；Corolla yellow-white, corolla lobe long round shape lanceolar.Female flower: Dan Shenghuo
Dilute cluster life；Bennet is sturdy, by pubescence；Ovary is coarse.Fruit Long Circle or cylinder, yellow green when ripe, rough surface.Seed
Little, narrow avette, white, non-flanged, the closely anxious point in two ends.Because Fructus Cucumidis sativi has high edibility and nutritive value, therefore yellow
The cultivation technique of melon just occurs in succession, and during cucumber cultivation, the control of fertilizer is particularly critical, because cucumber cultivation is in soil,
Applying fertilizer for a period of time after, except sub-fraction can by Fructus Cucumidis sativi absorb in addition to, others then can run off, and causes substantial amounts of wave
Take, in order to reduce this loss must be requested that the release rule of nutrient of fertilizer is coordinated with the Nutrient Absorption of Fructus Cucumidis sativi, therefore controlled release
Fertile development becomes more and more, the characteristic being directed to cucumber growth for this present inventor provide a kind of Fructus Cucumidis sativi special-purpose control-release fertilizer and
