Problems solved by technology

[0008] In order to solve the problem of low utilization efficiency of bio-organic fertilizer caused by traditional rice stubble flue-cured tobacco bio-organic fertilizer application or strip application technology, the traditional use of fire-soil ash as fertilizer for transplanting and poor fertilizer efficiency, fire-soil ash and pigs and cattle pens silt After fermenting, it can be used as a fertilizer to carry pathogenic microorganisms and process miscellaneous problems. The present invention provides a kind of fertilizer suitable for transplanting flue-cured tobacco with rice stubble.

Embodiment 1

[0081] Embodiment 1: Pot simulation test 1-screening of different bio-organic fertilizers

[0082] It will be conducted from September to November 2015. The variety of flue-cured tobacco is K326. The pH of the test soil is 6.71, the organic matter is 34.36g / kg, the alkaline hydrolysis nitrogen is 169.45mg / kg, the available phosphorus is 30.32mg / kg, and the available potassium is 101.21mg / kg. It is taken from the paddy field of Yunyuan base of Hunan Agricultural University. Dry and set aside. The bio-organic fertilizer used in the test is the attapulgite composite microbial organic fertilizer (Gansu Xinqing Environmental Protection Technology Co., Ltd., Xinqing brand, effective viable bacteria number ≥ 0.5 billion / g, organic matter ≥ 45%, N+P 2 o 5 +K 2 O ≥ 5%), tobacco straw bio-organic fertilizer (Xiangxi Tobacco Company, the number of effective viable bacteria ≥ 0.7 billion / g, organic matter ≥ 60%, N+P 2 o 5 +K 2 O≥5%), three cakes in one bio-organic fertilizer (Hunan...

Embodiment 2

[0101] Embodiment 2: Pot simulation test 2-a study on the amount of different bio-organic fertilizers

[0102] The experiment was carried out in the Tobacco Base of Hunan Agricultural University in 2015. The variety of flue-cured tobacco is K326. The potting test soil is paddy soil, the soil pH is 6.71, the organic matter is 34.36g / kg, the alkaline nitrogen is 169.45mg / kg, the available phosphorus is 30.32mg / kg, and the available potassium is 101.21mg / kg.

[0103] The bio-organic fertilizer used in the test is a three-cake-in-one bio-organic fertilizer (Hunan Jinye Zhongwang Technology Co., Ltd., Zhongwang brand, effective viable bacteria number ≥ 0.5 billion / g, organic matter ≥ 70%, N+P 2 o 5 +K 2 O≥8%).

[0104] Set up 9 treatments, namely: T1~T4, apply bio-fertilizer 25g / plant, 20g / plant, 15g / plant, 10g / plant respectively, fire soil ash is 500g / plant; bio-fertilizer and fire soil ash are not fermented;

[0105] From T5 to T8, 25g / plant, 20g / plant, 15g / plant, and 10g / pl...

Embodiment 3

[0121] Embodiment 3: field test

[0122] It was carried out in a base unit in Hunan Province in 2016. The experimental field is a flue-cured tobacco-late rice rotation tobacco field, and the soil is a representative local paddy soil, which is convenient for irrigation and drainage; the soil pH is 7.18, the organic matter is 42.34g / kg, the alkaline nitrogen is 224.86mg / kg, and the available phosphorus is 30.68mg / kg. Available potassium is 107.22mg / kg. The breed is K326. The organic matter of the three-cake-in-one bio-organic fertilizer ≥ 70%, N, P 2 o 5 、K 2 The O content is 5.0%, 1.5%, 1.5% respectively, and the number of effective viable bacteria is ≥ 0.5 billion / g; the N, P, and K contents of the tobacco-specific base fertilizer are 8%, 10%, and 11% respectively; the N, P, and K contents of the seedling fertilizer are respectively The contents of P and K are 20%, 0%, and 8.8% respectively; the contents of N, P, and K of special top dressing are 10.0%, 5.0%, and 29.0% re...

Abstract

The invention provides a rice stubble flue-cured tobacco transplanting safety fertilizer and its application method, which belong to the field of agricultural planting technology. Anhe fertilizer, Anhe fertilizer concentrated application of flue-cured tobacco root zone soil. The transplanting safety fertilizer of the present invention concentrates the advantages of fire soil ash and bio-organic fertilizer, does not carry pathogenic bacteria harmful to flue-cured tobacco, and has the functions of keeping warm and refreshing water, enriching microorganisms in the root zone of tobacco seedlings, and optimizing the micro-ecological environment of the root system; The invented transplanting safety fertilizer is concentrated on the soil in the root zone of tobacco plants, which can seal the gap between the tobacco seedlings and the large paddy soil, and the roots, soil and fertilizer are in full contact, so that the fertilizer is concentrated in the root zone of the tobacco seedlings and is easier to absorb , which is more conducive to the early and rapid growth of flue-cured tobacco, and has obvious effects of promoting growth, increasing production and improving quality.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for improving the soil environment in the root zone of rice stubble flue-cured tobacco and promoting the early growth and rapid emergence of flue-cured tobacco. Background technique [0002] Flue-cured tobacco with rice stubble (planting rice after harvesting flue-cured tobacco within one year) is the main way of flue-cured tobacco cultivation in southern tobacco-growing areas. During the transplanting of flue-cured tobacco in southern rice-growing tobacco areas, the low temperature and rainy weather, coupled with the large soil clods in the tobacco planting soil from the plowed paddy fields, lead to a large gap between the tobacco seedlings and the large paddy soil, which affects the early growth of tobacco seedlings. In order to make up for these defects, rice stubble flue-cured tobacco is often used when transplanting flue-cured tobacco to us...
