Problems solved by technology

Therefore it cannot be confirmed whether the production-increasing effect of the foliar fertilizer products developed by these wood vinegars is derived from the contribution of the wood vinegar; and the active ingredients contained in the wood vinegar are all trace amounts, and it is impossible to confirm the presence of the added components and the wood vinegar. Whether there is antagonism between the active ingredients

Embodiment 1

[0039] A foliar conditioner utilizing carbonization by-products of straw and remaining living room biomass, characterized in that the foliar conditioner is prepared as follows:

[0040] A. The straw and living cabinet residual biomass are dried to make m (water) < 10%, and then the obtained dry matter is ground to make the particle size < 3mm. The raw materials are put into pyrolysis equipment, and the carbonization temperature is 400~500 ℃ for anaerobic pyrolysis. After 2 hours of pyrolysis, it is separated by a separation device, and the collected liquid is filtered after static precipitation to obtain a stock solution of wood vinegar;

[0041] B. After standing for 1 week, filter through a microporous membrane to obtain a refined wood vinegar mixture. The pH of the refined wood vinegar mixture is 9.37, and the total organic carbon TOC content is 3.87 g·L-1.

Embodiment 2

[0043] 1. Formula of straw and wood vinegar foliage conditioner:

[0044] Recipe 1: 3.33g of refined mixture of straw and wood vinegar, mixed with 1kg of water, directly diluted.

[0045] Formula 2: urea 1.36g, potassium dihydrogen phosphate 0.34g, ammonium molybdate 0.034g, zinc sulfate 0.068g, copper sulfate 0.068g, boric acid 0.034g, magnesium sulfate 0.136g, ferrous sulfate 0.204g, manganese sulfate 0.034g, Calcium chloride 0.34g, EDTA 0.2728g, water 1kg; when preparing, first dissolve each component with the minimum amount of water according to the above proportions to obtain the aqueous solution of each component, then mix the EDTA aqueous solution with the ferrous sulfate aqueous solution, Then the aqueous solutions of other components were slowly added to the mixed solution of EDTA and ferrous sulfate, stirred while adding, and finally the obtained mixed solution was constant volume.

[0046] Formula 3: 3.33g refined mixture of straw and wood vineg...

Abstract

The invention relates to a foliage conditioner prepared from straw and household kitchen biomass carbonization byproducts and application thereof. A method for applying the foliage conditioner comprises the following steps of: standing a stock pyroligneous solution produced by thermal cracking of straw and household kitchen biomasses for a week; performing suction filtration with a microporous filtering film; and diluting a refined pyroligneous solution with water of which the amount is 300 times that of the refined pyroligneous solution, and applying the diluent to positive and negative foliage of plants at the beginning fruiting period of tomato for 3-4 times at the interval 7-10 days. Due to the adoption of the foliage conditioner, the application of inorganic fertilizers is reduced, the yield is increased by 250.91 g / plant simultaneously which is equivalent to the effect of an inorganic total nutrient solution, the Vc content of tomato fruits is increased remarkably, the ratio of soluble protein to sugar acid does not change remarkably but tends to increase, the resistance of plants is enhanced, and the continuous cropping obstacle is relieved to a certain extent; and moreover, the foliage conditioner is prepared from straw and household kitchen biomasses, belongs to a natural substance, is environmentally-friendly, has no toxic or side effect on human beings and livestock, and has low price.

Description

technical field [0001] The invention particularly relates to a liquid foliage crop conditioner prepared by using wood vinegar, a by-product of carbonization of straw agricultural and household waste, and its application, and relates to the field of industrial ecology. Background technique [0002] Wood vinegar, also known as plant acid, is a liquid product of the pyrolysis and carbonization process of biomass raw materials. It contains about 500 kinds of organic substances (mostly trace components) such as organic acids, alcohols, phenols, esters, carbonyls and furans, as well as Ca and Mg. , Na, Fe and other inorganic trace elements. Due to the difference in raw materials and preparation conditions, the contents of these components in wood vinegar vary. Wood vinegar has many functions such as promoting plant growth, disinfection, sterilization, pest control, anticorrosion, deodorization, and improvement of soil environment. According to the tests of Jin Shanyu, Watanabe,...
