Embodiment 1

[0020] A preparation method of phosphorus and potassium compound fertilizer in the whole growth period of tobacco, comprising the following steps:

[0021] (1) Harvest the green scallops that have entered the full flowering stage, cut them into small sections of 5-8cm after drying, carry out low-temperature carbonization in a carbonization furnace at 350 degrees, crush them, and pass through a 150-mesh sieve to make potassium-rich green scallops Biochar;

[0022] (2) Harvest the plants that have entered the full flowering stage and cut them into small sections of 5-8cm. Mix the green pea and rapeseed cakes in a weight ratio of 2:3, add 0.1% fermented bacteria to ferment, ferment for 40 days, and crush 1. Pass through a 150-mesh sieve to make potassium-rich decomposed green scorpion-rapeseed cake fertilizer;

[0023] (3) After drying the tobacco rods from which the tobacco leaves have been removed, crush them into small pieces of 2-4 cm in length, carry out low-temperature car...

Abstract

The invention provides whole-growing-season phosphorus and potassium compound fertilizer for tobaccos. The whole-growing-season phosphorus and potassium compound fertilizer is prepared from an organiccomponent prepared from feather cockscomb biomass carbon, composted feather cockscomb-rapeseed cake fertilizer, tobacco stem biomass carbon, phosphorus-dissolving bacteria, potassium-dissolving bacteria and attapulgite, and three inorganic components according to the mass ratio of 1 to (1 to 3), wherein the mass ratio of the inorganic component 1 to the inorganic component 2 to the inorganic component 3 is 1 to (1 to 2) to (1 to 2); the inorganic component 1 is prepared from silicon-phosphorus fertilizer, potassium sulfate, phosphorus humate and the attapulgite; the inorganic component 2 is prepared from ammonium polyphosphate, ammonium nitrate, medical stones and the attapulgite; the inorganic component 3 is prepared from potassium humate, phosphorus humate and the attapulgite. Accordingto the whole-growing-season phosphorus and potassium compound fertilizer for the tobaccos, the problems that the utilization rate of phosphorus fertilizer and potassium fertilizer for baking the tobaccos is low, phosphorus is enriched in soil and the potassium content of tobacco leaves is low are solved.

Description

technical field [0001] The invention belongs to the field of tobacco chemical fertilizers, and in particular relates to a phosphorus and potassium compound fertilizer in the whole growth period of tobacco and a preparation method thereof. Background technique [0002] At present, the source of potassium fertilizer used for tobacco is mainly water-soluble potassium sulfate and potassium nitrate and other chemical potassium fertilizers, which will be lost with rainfall and fixed by the soil, resulting in low utilization rate of potassium fertilizer, insufficient soil potassium supply in the late growth period, and tobacco leaf potassium. The content cannot be improved; there are some patents on the formula of silicon potassium fertilizer, humic acid potassium fertilizer and potassium sulfate, and the compounding of organic potassium fertilizer can reduce potassium fixation, form multiple peaks of potassium supply, and provide partial slow release at the same time Potassium pro...
