Abstract

The invented fertilizer includes composite chemical fertilizer and trace fertilizer and its characteristic lies in that it uses organic fertilizer and biological bacterial manure as maim parts and is formed by the mixing machine extrusion. Said fertilizer is a high strength formed fertilizer which uses organic fertilizer as main and aims at the characteristic of rice. It is a whole nourishment and high content organic commodity fertilizer. The economic and social benefits are notable. The experiment shows that under the prerequisit of 10-20% less than the chemical fertilizer application, the production is increased by 10-20%.

Description

Special organic shaped fertilizer technology for paddy rice

The invention belongs to the soil and fertilizer technical field.Exactly it relates to the extraordinary dedicated fertilizer of a kind of novel paddy rice.

At present, the paddy rice special organic shaped fertilizer does not also retrieve both at home and abroad, and close only paddy rice compound is fertile in the long-acting weeding of paddy rice composite fertilizer (being called for short the paddy rice one-time efficacious).One of its problem, the paddy rice one-time efficacious is a powdered fertilizer, after spreading fertilizer over the fields the paddy field, it is bigger to run off, that fertilizer efficiency is utilized is low, smell greatly, bicarbonate of ammonia type especially; Two of its problem, the paddy rice one-time efficacious belongs to chemical fertilizer, and life-time service descends soil organic matter content, is unfavorable for microorganism growth, influences soil fertility, and crop quality descends; Must does three of its problem, paddy rice one-time efficacious are meant respectively to topdress once carry out, but still base manure, and that base manure accounts for whole rate of fertilizer application ratio is very big, moreover satisfies much base manure amounts and just can demonstrate one-time efficacious?

Purpose of the present invention provides a kind of new special organic fertilizer, it is special large-scale fertilizer, make with the special process prescription organicly combine with inorganic fertilizer, with special fertilizer practice mechanical deep fertilizing fertilizer, make it to reach volume increase, increase income and improve the purpose of crop quality.

The present invention seeks to realize like this: (1) 50% fertilizer adds 2.9% bio-bacterial manure and adds 47% chemical fertilizer and add 0.1% little fertilizer; (2) through mixing machinery extrusion forming fertilizer; (3) envelope; (4) manual or equidistant deep placements of machinery realization of bulk application.

Now in conjunction with the embodiments, specifically illustrate the present invention.According to soil type, through surveying soil and paddy rice target output, determine crop need nitrogen, phosphorus, potassium and in, micro-requirement, calculate rate of fertilizer application, weigh in proportion, mixing, moulding, pack, use.

The present invention and existing paddy rice one-time efficacious etc. relatively, its advantage and positively effect are: (1) this fertilizer is special first cake type fertilizer, intensity height, long preservative period, odorlessness can slowly discharge nutrient, for whole plants vegetative period, can reduce fertilizer efficiency loss 20-30%; (2) this fertilizer be organic be main commercial fertilizer, collection fertilizer, bio-bacterial manure, mixed fertilizer, little fertilizer are combined into one, existing trophism again can be in the structure of improving the soil, and there is its effect unique increase organic matter, content of humic acid, culture fertility, microorganism growth aspect; (3) each time topdressed and the base manure applied once gets final product, reduce peasant's labour intensity, laborsaving, save time, save money; (4) economic benefit and social benefit are obvious.Through several years in the Yongji, test in a county level such as farming peace etc. tests that the result shows and chemical fertilizer drops under the 10-15% prerequisite than lacking, increase production more than the 15-20%, and obvious social in addition.

Claims

1, a kind of paddy rice special organic shaped fertilizer, it comprises mixed fertilizer, trace element fertilizer, it is characterized in that:

(1) also having fertilizer, bio-bacterial manure is main part;

(2) through mix, the special type fertilizer of mechanical extrusion forming.
