Abstract
The regulator for growing rice seedling of northeast district of China is made up by using ammonium sulfate, ammonium superphosphate, calcium superphosphate, potassium sulfate, zinc sulfate and sulfuric acid as main raw matrials. Said invented main composition formula is: N 5.6-7.6%; P2O5 2.8-4.8%; K2O 0.6-2.6%; Zn 0.15-0.35%; humic acid 2-6%; pH 0.8-1.6. The sulfuric acid carrier and dispersant are about 35-50%. These raw materials are easily available, and the mixing proportion of them is reasonable. It uses furfural as dispersant to improve physical properties of said product, and adds humic acid to provide activating matter for promoting growth of seedlings, so that its efficiency is high.
Description
The present invention relates to the technology of meticulous organic chemical industry aspect.It is a kind of physiologically active of plant material that contains.The product of this technology generally is used for China's the Northeast's dry seedling bed of rice.
Seedling cultivation of rice needs the useless suitable soil environment of soda acid, and a last PH4.5-5.5 that grows seedlings is suitable for nursery period rice seedling growth most; Simultaneously, seedling growth also needs to absorb various nutrient elements.For this reason, should use acidic materials to adjust soil acidity in the nursery period management of seedbed, must repeatedly apply fertilizer again and could satisfy the needs of rice shoot for nutrition.Thereby repeatedly operation, very inconvenience directly uses sulfuric acid as acid adjustment material and dangerous property.
Plain edition bed soil amendment nutrient is incomplete, lacks the potassium element, and the nutritive element proportioning is unreasonable, and the acid substance of dosing that carries accounts for total composition more than 55%, invalid components height, big (the every m of amount of application
2Restrain with 500-700), be not easy to transportation, caking is arranged, the peasant uses inconvenience, compare with " the neat female agent of bed soil modulation " in addition, this is that distant northern paddy rice technical research institute develops, though amount of application has reduced, is convenient to transportation, but nutrient formulation is reasonable inadequately, phosphorus, potassium, zinc contain quantity not sufficient, make the sulfuric acid carrier with rice husk, unhelpful acid consumption is heightened.Use fused calcium magnesium phosphate to make raw material again, also neutralize volume sulfuric acid, the acid adjustment effect is reduced.
Purpose of the present invention discloses a kind of high quality rice seedling growing regulator that contains physiologically active of plant, stimulates the purpose that absorb and have inhibition rice seedling rot of growth of seedling enhancing to nutritive element to reach.
Flesh and blood of the present invention is:
The content abundance of nitrogen of the present invention, phosphorus, potassium, zinc and proportioning are suitable, make dispersant with furfural slag, and the present invention does not use fused calcium magnesium phosphate so can increase product acidity for acid because of it, can avoid the unhelpful consumption of acid, has improved the validity of phosphorus among the present invention.
The present invention is a primary raw material with ammonium sulfate, ammonium acid phosphate, superphosphate, potassium sulphate, zinc sulphate, sulfuric acid, raw material are easy to obtain, nutrient is complete, reasonable mixture ratio, make dispersant with furfural slag and can improve the product physical property, not luming is easy to use, and has increased rotten cumfrey for promoting that seedling growth provides active substance.Consumption only is medium-sized 1/2 less, and the effect height is convenient to transportation, has increased the peasant economy benefit.

Dose the fenaminosulf bactericide in the serious region of disease of damping off.
Production method: adopt artificial stir synthetic, or with mechanical agitation produce all can, product is a grey black toner shape, plastic bag sealing packing, the term of validity 2 years.
Good effect of the present invention:
Use the present invention can make seedling bed earth be adjusted into acidity or subacidity, for favourable soil condition has been created in the healthy and strong growth of rice shoot; Applied once can satisfy the various nutrient elements of rice seedling bed phase needs, has satisfied the requirement of nursery period growth for nutrition; The present invention can stimulate growth of seedling because of containing the physiologically active of plant material, and the absorption, the length that strengthen nutritive element are long; Also has the effect that obviously suppresses the rice seedling damping off.Use this product to provide material base for cultivating strong seedling.This product generally is applicable to China's the Northeast's dry seedling bed of rice.Use this product with acid adjustment is finished in one-stop operation, the repeatedly operation of applying fertilizer can reach purpose.
This product in the period of 1994-1996 three as trial target in Yingkou, regional trial effects such as Haicheng City, Shenyang, Kaiyuan, new people are good, the rice shoot plant height increases, tiller number increases, the blade birth is fast, well developed root system, seedling is strong.
Act on bed soil PH of the present invention and can reduce 0.5-2.0 unit, keep soil acidity or subacidity to continue 25-30 days.It is fast to turn green after the transfer, and tachyauxesis is tillered ahead of time, and number of productive ear increases, for the later stage increasing production of rice lays the foundation.Using the seedling incidence of disease of the present invention obviously reduces.The present invention can increase production rice yield 5-10%
