Abstract

The present invention relates to a fertilizer special for watermelon. According to the requirements of the growth of the watermelon for macro elements and land capability conditions, the reasonable proportion of the content of N, P and K in the special fertilizer is disclosed, and micro elements of B and Zn and plant growth hormones, which are necessary for the growth of the watermelon, are added in the special fertilizer. The application of the fertilizer special for watermelon can increase the yield per mu of the watermelon by 18 to 20%, can increase sugar content by 1.54%, and can obviously increase the quality of the watermelon.

Description

Composite fertilizer special for watermelon

The present invention relates to the compound manure field.

Watermelon is the administration's good merchantable brand that quenches one's thirst that disappears that people like, also is lucrative cash crop.Because increasing rapidly of cultivated area, farm manures such as the sauce that tradition is used is done, soya-bean cake, plant ash kitchen range soil can not satisfy the needs that watermelon is produced far away, and for this reason, people begin the new source of manure of chemical fertilizer as watermelon.But blindly that each macroelement chemical fertilizer is blended together as fertilizer special for watermelon, the n-p-k element that has caused watermelon production to need is out of proportion, and quality of watermelon descends, show that watermelon saccharinity descends, acidity increases, and palatability is poor, the excessive growth of melon body, percentage of fertile fruit is low, and disease and pest is serious.Simultaneously, also caused the waste of fertilizer.

Academy of agricultural sciences, Shanghai in 1986 watermelon chemical fertilizer that clay fertilizer was once studied, but only be the test of " spraying the blade face to improve watermelon saccharinity with trace element ", do not relate to the fertilizer that puts in the soil; 1987, the test of " aspermous watermelon rational application of fertilizers " was done the academy of agricultural sciences in Guangdong Province, had proposed that nitrogen effective constituent is 13-40 in the composite fertilizer; Nitrogen: phosphorus: potassium=1: 1,1: 1,5.By the composite fertilizer that this prescription is manufactured, active constituent content is too high, and cost also improves thereupon.

The purpose of this invention is to provide a kind of composite fertilizer special for watermelon, N-P-K content is suitable for the growth of watermelon in this fertilizer, and can give full play to the effectiveness of each element; Simultaneously, necessary for plant growth trace element and plant hormone in fertilizer, have also been added.Use this composite fertilizer special for watermelon, but big area improves the yield and quality of watermelon.

Main points of the present invention are according to watermelon nutrient uptake feature and the effect of each mineral element to watermelon.With macroelement chemical fertilizer, trace element and hormone in required ratio through pulverizing, mixing, granulation, sieve, technology such as drying makes.Effective constituent N-P-K content in the compound manure is counted by amount of element:

Nitrogen: 8～20(weight unit, down together)

Phosphorus: 5～15

Potassium: 7～20

Adding contains micronutrient boron, zinc fertilizer material, and addition is:

Boron: 0.5～2.0 kilogram

Zinc: 0.5～2.4 kilogram

Contained according to " fertilizer is used knowledge " P196 that Science and Technology of Shanghai press publishes nineteen eighty-three, the trace element fertilizer nutrient content is to borax (Na ₂B407.10H ₂O), the content of element boron is 11.3%; To zinc sulfate ZnSO ₄.H ₂O), the content of zinc element is 35%, and converting above-mentioned according to this is that boron zinc element content is in the fertilizer of unit by kilogram:

Boron: 0.06～0.23;

Zinc: 0.18～0.84

The preparation composite fertilizer special for watermelon, also can add the EF hormone therein, this be a kind of serve as the plant growth promoter that make on the basis with the intravital natural bioactivity substance of plant, use EF, can strengthen vegetative function, enhance metabolism, improve crop quality, increasing both production and income.Addition is 0.04～0.10.

During the preparation composite fertilizer special for watermelon, can select the finished product that contain above-mentioned effective constituent for use, as: the ammoniacal liquor in the nitrogenous fertilizer, urea; Potassium primary phosphate in the phosphate fertilizer, monoammonium phosphate; Vitriolate of tartar in the potash fertilizer, Repone K; Optional EF plant growth promoter of hormone and zinc sulfate, borax or the like.According to the requirement and the finished product content thereof of the effective constituent in the prescription, how many finished products obtain needs, and the finished product chemical fertilizer that will contain various effective constituents then is together composite by technology.

Below provide several specific embodiment of the present invention:

1, nitrogen: 10

Phosphorus: 6

Potassium: 7

0.5 kilogram of boron: 0.0565(folding borax)

1 kilogram in zinc: 0.35(folding zinc sulfate)

Get nitrogen content as calculated and be 46% 21.7 kilograms in urea (include available nitrogen and be this routine desired number), phosphorus content is 42.9 kilograms of 14% general calcium, potassium content is 14 kilograms of 50% vitriolate of tartar, 0.5 kilogram of borax, 1 kilogram in zinc sulfate, with these several compositions through pulverizing, mix, sieve, promptly can be made into uniform composite fertilizer special for watermelon after the technology such as drying.

2, nitrogen: 10

Phosphorus: 10

Potassium: 15

1.0 kilograms of boron: 0.133(folding boraxs)

1.2 kilograms in zinc: 0.42(folding zinc sulfate)

EF hormone: 0.05

3, nitrogen: 20

Phosphorus: 15

Potassium: 20

1.5 kilograms of boron: 0.17(folding boraxs)

2.0 kilograms in zinc: 0.70(folding zinc sulfate)

EF hormone: 0.07

4, nitrogen: 17

Phosphorus: 10.5

Potassium: 15.2

1.2 kilograms in zinc: 0.42(folding zinc sulfate)

0.8 kilogram of boron: 0.09(folding borax)

Hormone: 0.06

By method preparation composite fertilizer special for watermelon provided by the invention, be applied to melon ground, show through 3 years test-results:

1, increase yield significantly, the economic benefit height.Use this fertilizer than other fertilizer, every mu of volume increase 18～20%, every mu of pure increasing income into 202 yuan (by 1988 annual price conversions);

2, soluble solid improves 2～3%;

3, total sugar content improves 1.54%;

4, organic acid content descends 17.35%;

5, Vitamin C content improves 13.5%.
