Abstract

A kind of foliar nutrient of controlling plant diseases, trace element such as the main nutrient element of the nitrogen that contains, phosphorus, potassium and iron, copper, zinc, boron, calcium, molybdenum, cobalt and sterilization, prevent and treat the material of disease, the preparation method is that will to contain the salt of various elements earlier water-soluble at normal temperatures, add the organic acid aqueous solution again, add tensio-active agent then; This means for leaf feeding of plants can promote plant-growth, increases harvest, and control plant multiple diseases is applicable to that blade face of plants such as paddy rice, corn, peanut, beans, sugarcane, mulberry tea, flowers, medicinal material and fruit tree or fruit growth period spray, and increase harvest 7-15%.

Description

The leaf fertilizer and the making method of controlling plant diseases

The present invention relates to a kind of controlling plant diseases and promote foliar nutrient of its growth and preparation method thereof.

Growth and development of plants is except the nutrient element that needs nitrogen, phosphorus, potassium, also need various trace elements, as iron, copper, zinc, boron, calcium, cobalt, molybdenum etc., these element of plant absorbing generally is to obtain in the soil, but will hinder plant-growth when soil lacks or absorbs when bad, remedial measure is these nutrient elements and trace element to be made liquid fertilizer be sprayed onto on the blade face of plant.And, for prevention and elimination of disease and pests, need apply various agricultural chemicals to plant.

How existing leaf hypertrophy just has the material of plant-growth, also notice and add various effect of trace elements, Chinese patent CN85103471,87100319,86105209 etc. all is examples of this respect, but these plant growth agents only work to promote growth to plant, can not prevent and treat disease, when plant is caught disease, must purchase agricultural chemicals in addition, so both the peasant be increased expenditure, make pesticide residue influence the healthy of people again.

The object of the present invention is to provide a kind of stimulating plant necessary element of growing that contains to have the material of some sterilization again, make plant is played the short long foliar nutrient that effect can prevent and treat disease again that increases income.

In order to reach this purpose, the present invention is with the material as nitrogen, phosphorus, the main nutrient element of potassium such as common nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, also use the micro-materials of conduct such as metal-salts such as copper, iron, zinc, cobalt, magnesium, molybdenum, can in the aqueous solution, stablize in order to make above material, also must add some organic acids as complex compound, in addition, add certain amount of surfactant, can make solution more be evenly dispersed on the plant leaf surface, increase its receptivity, at last, add some sterilizations, germ-resistant material, just can play the effect of diseases prevention.

Below be several embodiments of the present invention:

One, ammonium nitrate potassium primary phosphate copper sulfate

Zinc sulfate sal epsom sodium tetraborate

Ferrous sulfate ammonium molybdate EDTA sodium salt

Sulphur benzene sulfonic acid sodium salt potassium permanganate

The cobalt chloride citric acid

Two, urea ammonium hydrogen phosphate Repone K

Copper sulfate zinc sulfate sal epsom

Sodium tetraborate ferrous sulfate ammonium molybdate

Sodium salts humic acids sulphur benzene sulfonic acid sodium salt

Potassium permanganate cobalt chloride citric acid

Three, urea Sodium salts humic acids potassium primary phosphate

Copper sulfate zinc sulfate sal epsom

Sodium tetraborate ferrous sulfate ammonium molybdate

Cobalt chloride sulphur potassium permanganate

Benzene sulfonic acid sodium salt

Compound method: with the according to the form below content preparation of respectively filling a prescription of above embodiment.

The material of each component is calculated, be dissolved in less water after the weighing at normal temperatures, sulphur grinds to form 100-120 purpose granularity and adds, abundant mixing, add aqueous solutions of organic acids, (Sodium salts humic acids is pressed the 1-5 grams per liter) is diluted to volume, add benzene sulfonic acid sodium salt at last by every liter of solution 1-5 gram, be diluted to the liquid that volume promptly obtains brown, at this moment, the PH of solution is 2-5, Baume concentration is 10-25, proportion 1.18-1.20.

The optimum content of this solution is:

The present invention can be used for the blade face of the plants such as paddy rice, corn, peanut, beans, sugarcane, sesame, melon dish, flower, medicinal material and fruit tree and the sprinkling of fruit in growth period, through test in the past few years, proof has the earlier cooperation of the plant of promotion with improving the plant physiology and biochemistry balance, thereby promote the growth of plant, effect of increasing production, and the nutritional labeling of raising fruit. Be used in the test result on the paddy rice, rate of growth reaches about 7～15%.

The present invention is to rice blast, banded sclerotial blight, and bacterial leaf-blight, brown spot, big or small leaf spot, pestalotiopsis funerea, sitting root and stem of certain plants physiology disease has obvious preventive and therapeutic effect.

Below be the simultaneous test of Guangxi Agriculture College, and increased disease prevention effect comparison example:

The foliage fertilizer that compared test in 1987 in the rice field of Guangxi Agriculture College's medium fertility has: the present invention, and triacontanol price quote, chamber, blade face, to plant and increase agent, potassium primary phosphate, experimental cultivar is for very selecting 42.Each test site nitrogen phosphorus potassium level is identical, and control measures are identical.Its test-results is as follows:

Guangxi plant protection master station in 1986 uses the present invention and some agricultural chemicals to preventing and treating the result that prevents and treats of several diseases of paddy rice,

Tested variety and agricultural chemicals,

Banded sclerotial blight: use 5% jinggangmeisu (Jieyang, Guangdong insecticide factory product)

Rice blast: use 40% iprobenfos (water chestnut lake, Zhejiang laboratory product)

Bacterial leaf-blight: use 20% phenazine oxide (Japanese imported product)

	The present invention	Jinggangmeisu	Iprobenfos	Phenazine oxide
					Rice blast	60.57%	63.66%
Banded sclerotial blight	73.05%	82.24%
					Bacterial leaf-blight	57.10%		63.86%
