Embodiment 1

[0014] A kind of tobacco fertilization method of the present invention has conservation effect on tobacco planting soil, comprises the following steps: a. Apply base fertilizer: 20 days before tobacco transplanting, ditch is made on the land after levelling, and ditch interval is 120 centimeters, and ditch depth is 10 -15cm, ditch width 8-10cm, mix the fertilizer and apply it on the bottom of the ditch, and then ridge; apply bio-organic fertilizer 150-210kg, tobacco special fertilizer 20-28kg, potassium sulfate 9.5-13.3kg and Superphosphate 25-38kg; b. Transplanting: transplanting according to the requirements of high-quality tobacco leaf field management technical regulations; c. Topdressing seedling fertilizer: transplanting for 7 days, and planting 15cm deep at a distance of 15-20cm from the tobacco plant For the topdressing hole, apply 4.4-6.2kg / mu of ammonium nitrate with water, and seal the fertilization hole with soil after fertilization; Make a hole in the middle of th...

Embodiment 2

[0016] In 2013, 500 mu of land was demonstrated in Yuanbao Town, Lichuan City, including 50 mu of conventional fertilization technology; the soil in this area is yellow-brown soil with high fertility, convenient irrigation and drainage, good lighting conditions, complete baking facilities, and convenient transportation.

[0017] 1. Base fertilizer application: On April 5, ditch the flattened land with an interval of 120 cm, a ditch depth of 10-15 cm, and a ditch width of 8-10 cm. Apply the mixed fertilizer strips to the bottom of the ditch. Then ridging: 150kg / mu of bio-organic fertilizer per mu, 20kg / mu of special fertilizer for tobacco, 9.5kg / mu of potassium sulfate and 25kg / mu of superphosphate.

[0018] 2. Topdressing seedling fertilizer: On May 3, drill a topdressing hole about 15cm deep at a distance of 15-20cm from the tobacco plant, apply ammonium nitrate 4.4kg / mu with water, and seal the fertilization hole with soil after fertilization .

[0019] 3. Potassium topdres...

Embodiment 3

[0021] In 2013, 1,000 mu of land was demonstrated in Xuan'en Xiaoguan, including 100 mu of conventional fertilization technology; the soil in this area is yellow-brown soil with medium fertility, convenient irrigation and drainage, good lighting conditions, complete baking facilities, and convenient transportation.

[0022] 1. Apply base fertilizer: On April 1st, ditch the flattened land with an interval of 120cm, a ditch depth of 10-15cm, and a ditch width of 8-10cm. Apply the mixed fertilizer strips to the bottom of the ditch. Then ridges were applied; 180kg / mu of bio-organic fertilizer, 24kg / mu of tobacco special fertilizer, 11.4kg / mu of potassium sulfate and 21.3kg / mu of superphosphate were applied per mu.

[0023] 2. Topdressing seedling fertilizer: On May 2, make a topdressing hole about 15cm deep at a distance of 15-20cm from the tobacco plant, apply the remaining 30% nitrogen fertilizer ammonium nitrate (including N34%) 5.3kg / mu, mix with water After fertilization, sea...

Abstract

The invention relates to a tobacco fertilization method capable of conserving tobacco-planting soil. The tobacco fertilization method is characterized by comprising the following steps: a, fertilizing base fertilizer; b, transplanting; c, further applying seedling fertilizer; d, further applying potash fertilizer; and e, carrying out field management measures. By adopting the tobacco fertilization method capable of conserving the tobacco-planting soil, the volume weight, overall porosity, capillary porosity and aeration porosity of the soil are reduced, so that the capillary moisture capacity and moisture content of the tobacco-planting soil are increased, the quantity of microbes in the soil is increased, the pathogenic bacteria of tobacco bacterial wilt are reduced, and the yield, output value, average price and high and medium tobacco rate of tobacco are obviously improved.

Description

technical field [0001] The invention relates to a tobacco fertilization method which can protect tobacco planting soil. Background technique [0002] Tobacco leaf is one of the main economic crops in mountainous areas. In order to reduce labor and cost, improve quality and increase efficiency, tobacco farmers one-sidedly pursue the economic benefits of tobacco planting, neglect the soil fertility conservation of tobacco planting soil, and only use chemical fertilizers in tobacco leaf production for a long time, resulting in Soil compaction, acidification, aggregate structure damage, poor tillability, lack or imbalance of nutrients in the soil, etc. The degraded soil environment is not conducive to the normal growth of tobacco plants, and at the same time leads to the aggravation of tobacco diseases, which are becoming more and more serious. The degradation of tobacco planting soil has become one of the bottleneck problems in the sustainable development of tobacco leaf produc...
