Abstract

A special straw-stalk product contains N,P,K, trace elements (Zn, S and Mg), and the substances for sterilizing, and prepventing and treating diseases and features its functions of both agricultural chemical and fertilizer. Its advantages include no by-effect to crops, high effect on increasing yield and quality of crops and protecting environment.

Description

A kind of special product using straw or stalk as fertilizer

The present invention relates to a kind of special product using straw or stalk as fertilizer.This product is made up of urea, potassium primary phosphate, zinc sulfate, sal epsom, fenaminosulf, has medicine, fertile economic benefits and social benefits, does not contain hormone.

At present, the chemical fertilizer that circulates on existing technology and the market, little fertilizer, composite fertilizer, growing agent, agricultural disinfectant, sterilant be we can say too numerous to enumerately many.But can prevent and treat the mashed root of the dead seedling of the crop that causes behind the straw directly returning to field, sequela such as poor growth, the product that can increase production, increase income, increase matter does not again also have.Therefore, at present and the straw-returning technology promoted of tradition, all require the stalk also field, back of becoming thoroughly decomposed.Such as: " ammonification stack retting technology ", " stack retting adds the decomposition agent technology ".

Straw-returning can reach with ground and increase soil fertility, and increases the soil organism, promotes the eucyclic purpose of soil, and this general orientation is correct.But above two kinds of technology in concrete operations, are not only taken the labor force, and are expensive, and often have little time on the time, and its effect of increasing production is not too obvious.The appearance of rotary ploughing machine for covering grass has solved straw-returning labor force's deficiency, not enough problem on the time.But owing to behind the straw directly returning to field, cause the dead seedling of ensuing crop to rot root easily, many sequela such as poor growth cause the unsteady problem of crop yield not to be resolved, and cause the application that makes rotary cultivator, and the popularization of existing in other words straw-returning technology is had difficulty in taking a step.So the someone advocates that a baked wheaten cake falls (for example peasant of Chengdu Plain), and competitively imitate.Like this, human space of depending on for existence has seriously been polluted in the not only most of nutrient loss of stalk, and thick smoke.

Behind the straw directly returning to field that becomes thoroughly decomposed, slow oxidation in soil causes some the micro-effective ingredient in the soil to reduce relatively easily, simultaneously, produces some to the deleterious material of crop root.The method that solves is exactly in time to replenish these trace elements targetedly, and uses the medicine that some are prevented and cured diseases.1996, I proposed: and a kind of plant agent for sterilizing and promoting growth and manufacture method thereof (application number is: 9611707.1), experimental result, though labor savings is increased production again, to the many sequela behind the straw directly returning to field, prevention effect is not so good.Through the improved a kind of special product using straw or stalk as fertilizer that the present invention relates to, support straw directly returning to field, especially machinery is gone back the field.Because the present invention can effectively prevent and treat the many sequela that cause behind the straw directly returning to field, thereby make that straw-returning becomes easily, confidence and be willing to be accepted.Through land for growing field crops preliminary examination, pilot scale all obtains the positive effect (adhesion test report) of diseases prevention, volume increase.

This product is rich in nitrogen, phosphorus, (nitrogen is provided by urea potassium; Phosphorus, potassium are provided by potassium primary phosphate) and various trace elements (trace element is provided by zinc sulfate, sal epsom), disinfectant (sterilization functions is provided by fenaminosulf).Fenaminosulf, chemical name:, cry again to Dimethylaminobenzene diazosulfonic acid sodium: fenaminosulf, itself just has the effect of sterilization to soil, it and trace element together, after stalk rotted, generation the deleterious material of crop root is had anti-effect short of money).

Raw material of the present invention is easy to get, and makes not too complexity, and cost is moderate.Product is powdery, can be water-soluble, and storing is convenient.The present invention both can bottom application when pressing grass, also can be in seedling spraying.The present invention is not only applicable to straw-returning, is applicable to that weeds lose leaf yet, be not subjected in the rubbish that chemical substance pollutes organic matter also use behind the field.The present invention can use separately, but cooperates straw-returning, or cooperates other organic matter to use, and its volume increase is more obvious, and the positively effect of 1+1＞2 is arranged, and the ratio of its input and output is more than 1: 10.
