Cultivation method for improving photosynthetic efficiency of tobacco

A technology of photosynthetic efficiency and cultivation method, which is applied in the field of cultivation to improve the photosynthetic environment of crops and increase production, can solve the problem that the cultivation technology and measures do not meet the technical needs of tobacco leaf production areas, do not promote intercropping or intercropping of other crops, and are not conducive to the cultivation of crops in Longgou. Improve the sensory quality of tobacco leaves, promote the formation of yield and quality, and facilitate ventilation

Problems solved by technology

For example, the patented three-dimensional planting method of wheat in furrows and ridges with the publication number CN1774970 discloses a method of raising ridges in the field and simultaneously sowing seeds on the ridges and in the furrows, so that the wheat field forms a high-light-efficiency canopy structure with ups and downs of wheat rows. The disadvantage is that direct sowing in the furrow is not conducive to the drainage and waterlogging of the crops in the furrow
Another example is that the patented rice terraced cultivation method with the publication number CN101904285A discloses a cultivation technique for raising paddy fields and planting rice respectively on both sides of the paddy f

Embodiment 1

[0018] Burley Tobacco Eyan No. 1 was used as the cultivar. figure 1 And attached figure 2 As shown, the high ridge specification with L1 as the longitudinal axis of the ridge body is ridge height h1 is 25cm, the ridge surface width a is 40cm, and the ridge bottom width c is 80cm, and the low ridge specification with L2 as the ridge body longitudinal axis is ridge height h2 ridge surface width b is 50cm, ridge bottom width c is 80cm, high and low ridge bodies are set at intervals, and the distance d between the longitudinal axes of adjacent ridge bodies is 120cm; when transplanting, the planting point P1 of high ridge tobacco plants deviates from the axis L1 of the ridge body The deviation distance e of the low ridge tobacco plant colonization point P2 from the ridge axis L2 is both 10cm, and the distance n between two adjacent plants on the same ridge along the longitudinal axis of the ridge is 50cm.

[0019] The existing cultivation method is a single ridge body height, the...

Embodiment 2

[0021] Take flue-cured tobacco K326 as the cultivar, as attached figure 1 And attached figure 2 As shown, the high ridge specification with L1 as the longitudinal axis of the ridge body is ridge height h1 is 25cm, the ridge surface width a is 40cm, and the ridge bottom width c is 75cm, and the low ridge specification with L2 as the ridge body longitudinal axis is ridge height h2 ridge surface width b is 60cm, ridge bottom width c is 75cm, high and low ridge bodies are set at intervals, and the distance d between the longitudinal axes of adjacent ridge bodies is 120cm; when transplanting, the planting point P1 of high ridge tobacco plants deviates from the ridge axis L1 The deviation distance e of the low ridge tobacco plant is 10cm, the deviation distance f of the planting point P2 of the low ridge tobacco plant from the ridge axis L2 is 15cm, and the distance n between two adjacent plants on the same ridge along the longitudinal axis of the ridge is 55cm.

Abstract

The invention discloses a cultivation method for improving the photosynthetic efficiency of tobacco, which belongs to the field of crop planting method. The cultivation method comprises specification and arrangement method of ridges of a tobacco cultivation land, and a transplanting method of tobacco plants; and the cultivation method is characterized in that high and low soil ridges are arranged at specified intervals, low ridges are arranged at two sides of each high ridge, and high ridges are arranged at two sides of each low ridge. The transplanting of tobacco plants is as follows: the tobacco plants are planted in a staggering way at two sides of the surface vertical axes of the high and low ridges with equal distance to the axes, the axial distances between the staggeringly planted adjacent tobacco plants are the same, and the tobacco plants are distributed in a wave mode on the surfaces of the high and low ridges which are arranged at intervals. Compared with the traditional cultivation method, the cultivation method disclosed by the invention enables the plant spacing to be increased by 4 to 14 centimeters, the net photosynthetic rate of tobacco growing stage is improved by 5 to 70 percent, the tobacco yield is increased by 10 to 30 percent, the quality of tobacco leaf is remarkably improved, and the harmful component TSNAs of tobacco is reduced by 5 to 30 percent so that the industrial usability of the raw tobacco material can be greatly improved.

Description

technical field [0001] The invention relates to a cultivation method for improving the photosynthetic efficiency of tobacco, which belongs to the field of crop planting methods, and in particular relates to a cultivation method for improving crop photosynthetic environment and increasing production. Background technique [0002] Compared with the world's high-quality tobacco leaf countries, my country's tobacco leaf producing areas generally suffer from insufficient light resources during the field growth period, which leads to varying degrees of restrictions on tobacco leaf production and quality. Improving the utilization rate of photosynthetically active radiation so as to improve the level of yield and quality has always been the goal pursued by the tobacco planting field. At present, there are three main ways to improve the utilization rate of photosynthetically active radiation of crops, that is, to increase the photosynthetic efficiency of crops: [0003] (1) Accordi...
