Abstract

The invention relates to a special fertilizer for watermelon cultivation, and particularly discloses a special organic-inorganic compound fertilizer for watermelons. The invention provides a special organic-inorganic compound fertilizer for watermelons. The special organic-inorganic compound fertilizer is prepared by the following steps: 1, adding 15% of fungus dregs, 10% of cigarette powder, 9.9% of reed residues and 0.1% of fermentative strain to 65% of dried poultry manure, so as to form fermenting materials, mixing evenly, stacking, and thoroughly decomposing at a high temperature of 60-65 DEG C, so as to prepare a biological organic fertilizer; and 2, proportionally mixing urea, ammonium dihydric phosphate, potassium sulphate, an organic fertilizer, caustic calcined magnesite (the magnesium oxide content is more than 75%), and a calcium-magnesia phosphate fertilizer, and stirring evenly, so as to prepare the special organic-inorganic compound fertilizer for watermelons. The special fertilizer integrates the advantages of the organic fertilizer and the ratio of the inorganic fertilizer according with the growth requirements of the watermelons; through cultivation by using the fertilizer, the special organic-inorganic compound fertilizer can meet the requirements of normal growth, development, production increase and increment of the watermelons on various nutrient elements; and the quality of the watermelons can also be significantly improved.

Description

A kind of watermelon special organic-inorganic composite fertilizer

Technical field

The present invention relates to cultivating watermelon dedicated fertilizer, specifically disclose a kind of watermelon special organic-inorganic composite fertilizer.

Background technology

The heath food in summer that watermelon is extensively eaten by people.Heat midsummer, often eat watermelon, have greatest benefit for human body relieving summer-heat, diuresis, toxin expelling.In China from south to north, from the east to the west, so side area, desert have cultivating watermelon.But special, the efficient organic-inorganic complex fertilizer of domestic still not good cultivating watermelon at present, grower is mainly with chemical fertilizer, general organic fertilizer, or organic fertilizer adds chemical fertilizer and cultivates, because its macroelement fertilizer fertilizer ratio is very unreasonable, the moderate-element such as calcium, magnesium lacks, so quality of watermelon and output are difficult to ensure, especially quality is difficult to be guaranteed.

Watermelon eats fruit to pluck raw for the purpose of fruit-watermelon.The demand percentage of growth to macroelement fertilizer of watermelon is more special.Result of study proves, the biological yield of watermelon is to nitrogen: phosphorus: the demand percentage of potassium is (2.1 ~ 2.2): 1:(3.4 ~ 3.5).Simple use chemical fertilizer is easy to be made into such ratio, but long-term practical fertilizer, make soil compaction, disease increases the weight of, yield and quality degradation.Simple manure use material, is difficult to again the nutrient met required for watermelon growing, and output is difficult to ensure.Melon grower wishes a kind of fertilizer: once use, and no longer topdresses after covering mulch film, can high yield, again can high-quality, and the present invention is exactly such fertilizer.

Summary of the invention

The object of the invention is to be improved according to the shortcoming existed in background technology and problem, provide a kind of fertilizer and ratio gathered to meet the advantage of the inorganic fertilizer of watermelon growing demand in the watermelon special organic-inorganic composite fertilizer of one.

Technical scheme of the present invention is to provide a kind of watermelon special organic-inorganic composite fertilizer, it is made according to the following steps: step one: with 65% dried poultrymanure add 15% edible fungi residues add 10% tobacco powder end add 9.9% reed end add 0.1% fermented bacterium composition fermentation raw material, water content is 40-45%, mix and bank up, bank up under high temperature 60 ~ 65 DEG C of conditions, become thoroughly decomposed, massfraction >=10% of the N P and K total nutrient of obtained biological organic fertilizer, the massfraction ratio of N P and K is nitrogen: phosphorus: potassium=4:3:3, organic massfraction is 75%, living bacteria count >=3,000 ten thousand/g, moisture less than 25%, PH is 7, step 2: the raw material of following masses per-cent is mixed, stirs,

Watermelon special organic-inorganic composite fertilizer can be obtained, the massfraction of the nitrogen in this watermelon special organic-inorganic composite fertilizer, phosphorus, potassium is (8.5 ~ 10.5) %, (4 ~ 5) %, (14 ~ 16) % respectively, massfraction≤12% of moisture, massfraction >=3% of medium trace element.

The present invention has the following advantages:

1, the present invention be a kind of gather fertilizer advantage, meet watermelon growing demand inorganic fertilizer ratio in the dedicated fertilizer of one.Use this fertilizer to cultivate, watermelon normal growth, growth can be met, increase production, increase income needs to various nutritive element, can quality of watermelon be significantly improved again.

2, distinctive feature of the present invention is growth according to watermelon, grows demand rule to fertilizer, sets all technical, especially the setting of the medium trace element such as calcium, magnesium index, other similar inventions different from the past.Use this fertilizer to carry out cultivating watermelon, the demand of watermelon to various macroelement, middle amount and trace element can be met, the characteristic such as the resistance of watermelon, yielding ability, pol, mouthfeel, storage endurance, resistance to transport is significantly improved.And using method is easy, once makes base fertilizer during film-mulching cultivation and use, no longer foliage top dressing in whole breeding time, only spray 1-2 foliage fertilizer at the middle and late growth stage and can realize cultivating object.
