Embodiment 1

[0026] The experiment site is Liuqu Village, Caojiawan Township, Long County, Baoji City. Select 9 mu of tobacco fields as the experimental site, of which 3 mu of tobacco fields are mixed with organic fertilizer and chemical fertilizer, topdressing fertilizer is applied in holes, and the tobacco field is irrigated with natural rainfall, as the experimental group T1, and the other 3 mu of tobacco fields are mixed with organic fertilizer and chemical fertilizer. Topdressing was treated with water and fertilizer integration, as the experimental group T2, and the last 3 mu of tobacco fields were only applied with chemical fertilizers, topdressing was applied in holes, and the tobacco fields were irrigated with natural rainfall, as the control group (CK). The variety of flue-cured tobacco is Liao 17, the organic fertilizer is distiller's grains, and the chemical fertilizer is special fertilizer for flue-cured tobacco, P fertilizer (P 2 o 5 ) and K fertilizer (K 2 O), distiller's ...

Embodiment 2

[0058] The experiment site is Xinwan Village, Datong Town, Hanbin District, Ankang City. Select 4 mu of tobacco field with organic fertilizer and chemical fertilizer, apply topdressing fertilizer in holes, and use natural rainfall to irrigate the tobacco field as the experimental group T1, and apply organic fertilizer and chemical fertilizer to the other 4 mu of tobacco field, and topdress fertilizer with integrated treatment of water and fertilizer, as the experimental group T1. In group T2, the other 4 mu of tobacco fields were only fertilized with chemical fertilizers, topdressing fertilizer was applied in holes, and natural rainfall was used to irrigate the tobacco fields, which served as the control group (CK). The variety of flue-cured tobacco is Yun 97, the organic fertilizer is rapeseed cake, and the chemical fertilizer is special fertilizer for flue-cured tobacco, P fertilizer (P 2 o 5 ) and K fertilizer (K 2 O). Rapeseed cake and chemical fertilizers were applied ...

Abstract

The invention discloses a water and fertilizer integrated drip irrigation method suitable for tobacco fields in dry seasons. Organic fertilizers and chemical fertilizers are applied in proportion, and are applied during ridging and the seedling stage, stretching stage, flourishing stage, and maturity stage of flue-cured tobacco. Water and fertilizer integrated drip irrigation supplements the necessary water and nutrients at different stages of the flue-cured tobacco growth period, improves the disease resistance of flue-cured tobacco, and reduces the incidence and disease index of climate spot disease. The invention is suitable for areas with less precipitation, drought years, inconvenient irrigation, and severe water shortages in dry seasons. The cost is low, the water and fertilizer utilization efficiency is high, and it is beneficial to the growth and quality improvement of flue-cured tobacco, and is suitable for the integrated management requirements of water and fertilizer in dry season tobacco fields. .

Description

technical field [0001] The invention belongs to the field of flue-cured tobacco cultivation, and in particular relates to an integrated drip irrigation mode of water and fertilizer based on combined application of organic fertilizer and chemical fertilizer, which is suitable for dry season tobacco fields. Background technique [0002] Flue-cured tobacco (Nicotiana tabacum L.) is a commercial crop for the purpose of harvesting tobacco leaves. Moisture is related to the intensity and direction of the metabolism of flue-cured tobacco, and also affects the formation and accumulation of various organic substances in flue-cured tobacco, which has a great impact on the yield and quality of tobacco leaves. For the tobacco fields that are inconvenient to irrigate and rely on rainfall to meet the moisture needs of flue-cured tobacco, once the rainfall is insufficient, it cannot meet the moisture and nutrient needs of flue-cured tobacco, which will affect the growth and development of ...
