Abstract

A chemical fertilizer especially suitable to culture seedlings and prevent diseases of fruit tree and vegetable contains such components as urea (20-34%), diammonium phosphate (25-40%), potassium sulfate (20-30%), and carbendazim (15-16%), and features the integration of pesticidal effectiveness with fertility to form a "pesticidal layer" in soil which can prevent fungi from intruding, and long effective period (about 30 days).

Description

Special-purpose medicine fertilizer--the seedling illness cleaning of one planting fruit-trees, grow seedlings of vegetable diseases prevention

The invention belongs to agrotechnique, particularly be applicable to the fertile manufacturing of the medicine field of fruit tree, greengrocery.

Background technology of the present invention is: at present, in China fruit tree, the grow seedlings of vegetable, often ignore the disease preventing and controlling, cause each fruit trees, vegetable sprout term anthrax, damping-off, the popular harm of samping off, cause in a large number and be short of seedling, even form mashed bed, dead seedling, loss greatly.Also have and much local adopt medicament kinds, soil disinfection and the back of emerging is sprayed ways such as killing the mattress medicament and prevented and treated, but often a little less than the growth of seedling gesture, growing way is poor, does not have the purpose of strong sprout, short seedling.

Main drawback shows:

1, control is missed the season, and disease infects;

2, control is single, and the lasting period is short;

3, can't treat in the disease high-incidence season;

4, medicine, the fertile disconnection, seedling is thin, a little less than the seedling;

5, to the disease of propagating in the soil control of can't sterilizing;

6, the masses dislike trouble, not glad the employing.

Purpose of design of the present invention is:

1, solves the soil disinfection problem.Each fruit trees, vegetable sprout term disease--damping-off samping off all is that the sclerotium state is present in the soil, and the common way that adopts all can not be killed sclerotium.Manage directly to kill sclerotium in the soil, hide bacterium amount of few soil that disappears plays anti-effect.

2, become " efficacy of a drug circle " and be " efficacy of a drug layer ", prolong the diseases prevention time.The past dressing seed is that formation is " efficacy of a drug circle " at center with the seed, the invasion of control germ seedling.But along with the germination of seed, taking root makes " efficacy of a drug circle " lose provide protection, generally the maintenance phase is 5-7 days.The present invention will form one " efficacy of a drug layer " in ten earth, not only can enlarge the sphere of action of efficacy of a drug circle, and owing to seed, growth of seedling phase mix mud with water are in the efficacy of a drug layer, the invasion of control germ, validity period reached about 30 days, kept away the critical porion that disease infects, and had played prophylaxis effect.

3, can play the effect of cultivating strong sprout.Fruit tree, vegetable cultivation strong sprout is the crux that improves transplanting survival rate, also is to obtain high yield, fine important step.Present technique adopts the combination of pesticide and fertilizer way, and diseases prevention and cultivation are combined strong sprout, can effectively improve seedling rate, for the land for growing field crops high yield lays the first stone.

4, can play the effect that drops into of saving.Way should be done dressing seed, soil disinfection, use seed manure routinely, does the seedling diseases control again, and is time-consuming, increases and drops into.Adopting the present invention can accomplish that " unification of four steps " reduce expenses and labor force more than 70%, is a kind of less investment, effective way.

The present invention's prescription is: urea 20～34%, phosphoric acid diamines 25～4%, vitriolate of tartar 20～30%, derosal 15～16%.All by weight percentage, derosal adopts the commercial goods, and all the other adopt industrial chemicals or commercial goods all can.

The present invention is a purpose to keep a full stand of seedings, selects interior suction, conduction, low toxicity for use, had the treatment and the sterilant of provide protection, and mainly be formation and the contact poison of disturbing imitative hypophysis in the germ mitotic division, make the germ protein coagulating, and play the effect of preventing and curing diseases.From cultivating strong sprout, add and mixed the necessary nutritive substance of seedling such as N.P.K, and promote the healthy and strong growth of seedling.

Using method of the present invention is very simple:

Earlier put the seedbed routinely in order at nursery stage, this agent is mixed with 10 times of fine earths spare then, be sprinkling upon surface, seedbed (whenever divide equally meter with this agent 50g) uniformly, with the watering utensil water is sprinkled upon the surface, till drenched, treats to ooze the back sowing under water, earth backing can change normal management over to again.

The present invention and technical background relatively have following advantage:

1, this product is a combination of pesticide and fertilizer, and both preventable disease was cured the disease, and can cultivate strong sprout again, restrains the deficiency of fertile single measure.

2, this product is split in soil layer that " efficacy of a drug layer 7 having overcome seed dressing before and being split into short defective of " efficacy of a drug circle " time length.

3, use this product can make seedling diseases descend 70～80%, make seedling diseases increase by 15～20%, the number of blade increases by 17～20, and the thick magnetic of stem adds 7～10%, and secondary root increases by 18～22%, and transplanting survival rate improves more than 20%.

Embodiment 1: take by weighing respectively mix behind urea 24kg, diammonium phosphate 40kg, vitriolate of tartar 20kg, derosal 16kg, the separated pulverizing stir the commodity seedling illness cleaning.

Embodiment 2: take by weighing respectively mix behind urea 30kg, diammonium phosphate 30kg, vitriolate of tartar 25kg, derosal 15kg, the separated pulverizing be incorporated in stirred 10 minutes in the agitator that per minute kind 30 changes finished product.

Embodiment 3: take by weighing respectively mix behind urea 21kg, diammonium phosphate 33kg, vitriolate of tartar 30kg, derosal 16kg, the separated pulverizing stir commodity.

Claims

1, a kind of special-purpose medicine fertilizer--seedling illness cleaning that is used for fruit tree, grow seedlings of vegetable diseases prevention is characterized in that containing urea, diammonium phosphate, vitriolate of tartar, derosal.

2, fruit tree according to claim 1, the special-purpose medicine fertilizer of grow seedlings of vegetable diseases prevention--seedling illness cleaning, it is characterized in that containing (in heavy per-cent): urea 20～34%, diammonium phosphate 25～40%, vitriolate of tartar 20～30%, derosal 15～16%, each component adds up to 100%.
