Embodiment 1

[0038] Embodiment 1: A drought-resistant and water-saving cultivation method for flue-cured tobacco

[0039] Including the following steps:

[0040] (1) Spring irrigation is carried out on the tobacco planting land one month before transplanting, using sprinkler irrigation, and the irrigation volume is 18m 3 / 666.7m 2 .

[0041] (2) 13 days before transplanting, the tobacco field was deeply plowed and sun-dried, weeds were removed and leveled, without large soil lumps, and the depth of plowing reached 28cm.

[0042] (3) if figure 1 As shown, adjust the distance between the blades of the ridging machine to 2.2m and then proceed to ridging. The height of the ridging is 28cm. After cultivating the soil, it reaches 30cm. The row spacing is 125cm, and the plant spacing is 58cm. Plant in wide and narrow rows, the crest of the wave is the tobacco planting row, double-row concave ridges, and plow a water collection ditch about 12cm deep in the middle of the ridges. The ridging m...

[0047] Embodiment 2: A drought-resistant and water-saving cultivation method for flue-cured tobacco

[0048] Including the following steps:

[0049] (1) One month before transplanting, spring irrigation was carried out on the tobacco planting land, using micro-spray irrigation, and the irrigation volume was 20m 3 / 666.7m 2 .

[0050] (2) Fifteen days before transplanting, the tobacco field was plowed and sun-dried, weeds were removed and leveled, without large soil lumps, and the depth of plowing reached 30cm.

[0051] (3) Adjust the distance between the blades of the ridging machine to 2.2m and then proceed to ridging. The height of the ridging is 30cm. After cultivating the soil, it reaches 35cm. The row spacing is 120cm, and the plant spacing is 60cm. Plant in wide and narrow rows, the crest of the wave is the tobacco planting row, double-row concave ridges, and plow a 15cm deep water collection ditch in the middle of the ridges. The ridging machine goes back and forth...

[0056] Embodiment 3: A drought-resistant and water-saving cultivation method for flue-cured tobacco

[0057] Including the following steps:

[0058] (1) Spring irrigation is carried out on the tobacco-planting land one month before transplanting, using micro-spray irrigation, and the irrigation volume is 22m 3 / 666.7m 2 .

[0059] (2) 18 days before transplanting, the tobacco field was deeply plowed and sun-dried, weeds were removed and leveled, without large soil blocks, and the depth of plowing reached 32cm.

[0060] (3) Adjust the distance between the blades of the ridging machine to 2.2m and then proceed to ridging. The height of the ridging is 32cm. After cultivating the soil, it will reach 32cm. The row spacing is 115cm, and the plant spacing is 62cm. Plant in wide and narrow rows, the crest of the wave is the tobacco planting row, double-row concave ridges, and plow a water collection ditch about 18cm deep in the middle of the ridges. The ridging machine goes back ...

Abstract

The invention discloses a drought-resistant and water-saving cultivation method for flue-cured tobacco, which comprises the following steps of: deep ploughing and land preparation combined with springirrigation; double-row and concave ridging; applying water retaining agent and root promoting agent in a tobacco pit; covering or returning straws; according to the ecological climate characteristicof the tobacco area, carrying out transplanting by using a deep planting method with small seedling films; carrying out the steps of field management measures and the like for drought resistance and preserving entropy. By using the method, the drought resistance of the flue-cured tobacco can be effectively improved, a good soil environment is provided for the growth and development of the flue-cured tobacco, the proportion of the three phases (solid phase, liquid phase, gas phase) of the soil is adjusted, the problems of insufficient effective raining and large difficulty of drought resistancewhen transplanting the flue-cured tobacco in regions with severe spring drought are solved, the soil structure is improved, the soil moisture nutrient loss is reduced, the utilization ratio of the water and fertilizer is improved, the straw covering is used as a mode of reasonable utilization of the straws, the transplanting survival rate of tobacco seedlings can be greatly improved, and the yield, the output value and the economic benefit of the tobacco leaves can be improved.

Description

technical field [0001] The invention relates to the technical field of flue-cured tobacco cultivation and farming, in particular to a flue-cured tobacco that combines spring irrigation, deep plowing, double-row concave ridges, high ridges, application of water-retaining agents, root-promoting agents, straw mulching or returning to the field, and deep planting of small seedlings under mulch A drought-resistant and water-saving cultivation method. Background technique [0002] Although there is abundant rainfall in my country's tobacco areas, the distribution of rainfall is uneven. Periodic droughts often occur in the middle and late stages of tobacco plant growth, and fertilizer and water cannot be coupled, which affects the growth and development of tobacco plants and the quality and availability of upper leaves. Therefore, drought resistance in the field is particularly important for stabilizing the yield of tobacco leaves and improving the quality of tobacco leaves. [00...
