Problems solved by technology

The process of cutting seedlings needs to be based on the growth of the tobacco seedlings. Cutting the seedlings is difficult and the human factors are relatively large. If you are not careful, it is likely to cause irreparable damage to the tobacco seedlings, resulting in a low rate of tobacco seedlings. Seedling survival rate is not high and other defects, and multiple thinning will also increase the risk of disease transmission to a certain extent

Embodiment 1

[0061] 1. Site construction

[0062] One is to choose a shed site. The nursery site is chosen to be leeward and sunny, with flat terrain, low groundwater level, close to clean water sources, convenient irrigation and drainage, convenient transportation, rice fields or dry land where Solanaceae and Cruciferous crops have not been planted before, and isolated from poultry and livestock. It is forbidden to build sheds or nursery workshops at the tuyere, at the root of the mountain, or at places with high groundwater levels. The second is to build sheds and pools. The greenhouse built is Wulian sports seedling greenhouse. There is a shoe sole disinfection pool at the entrance of the greenhouse, which is disinfected with bleaching powder. When cutting leaves, the greenhouse is provided with 2 interstices longitudinally for each span, and each span is divided into 6 standard nursery ponds with a size of 19.75m×2.4m, and cement milk slurry is scraped inside the nursery ponds. Can...

Embodiment 2

[0085] Embodiment 2 is the impact test of different transplanting methods on the yield and quality of flue-cured tobacco

[0086] Compared with example 1, the seedling raising and pulling out method of example 2 is the same as example one, and the difference is only that in the process of transplanting and covering film, a control experiment is set, which is respectively transplanting under the film (T1, embodiment 1 scheme) and on the film Transplantation (T2, control).

[0087] The experiment was divided into two transplanting methods: transplanting under the film (T1) and transplanting on the film (T2). The floating seedlings with five leaves and one heart were selected for transplanting under the film and transplanted under the film according to the "Technical Regulations for the Cultivation of High-quality Tobacco Leaf". The large area is 0.5 mu (550 plants). The floating seedlings with eight leaves and one heart were selected for transplanting on the film and transplant...

Embodiment 3

[0091] Embodiment 3 is the summary of different coverings on tobacco leaf yield, quality impact test

[0092] Compared with Example 1, the way of raising and pulling out seedlings of Example 3 is the same as Example 1, the only difference is that in the process of transplanting and covering film, a control experiment is set, respectively, processing one (T1) is a routine treatment, and no covering is taken. Measures (i.e. the control treatment); treatment two (T2) adopts white microfilm covering; treatment three (T3) adopts straw covering,

[0093] There were 3 treatments in this experiment and 3 repetitions. The area of ​​each plot is 60 square meters, the spacing between plants is 0.5m, and the row spacing is 1.2m. There are 6 rows planned for each plot, 15 tobacco plants are planted in each row, and 90 tobacco plants are planted in each plot. The settings of each treatment are as follows: treatment one (T1) is a conventional treatment without any mulching measures (i.e. co...

Abstract

The invention discloses a plant pulling and under-membrane transplanting method for floating tobacco seedling raising, and relates to the technical field of tobacco planting. The method comprises the following steps: performing field building, preparing seedling raising plates and seedling raising substrates, loading the substrates to the plates and performing sowing, and performing management in a seedling stage to obtain strong seedlings; transplanting the strong seedlings in the seedling raising plates to tobacco ridges in time and in batches through an under-membrane transplanting method; and continuing to cultivate remained weak seedlings for 3-5 days, wherein the strong seedlings are tobacco seedlings which have a stem height of 6-10cm and a stem girth of 1-2cm, have 4-5 functional leaves, are subjected to leaf shearing for 1-2 times, are hardened for not less than 10 days, and have a seedling age of 60-70 days. According to the invention, the method for flue-cured tobacco seedling raising has the advantages of intensification, management normalization, tobacco seedling growth accordance, less diseases and insect pests, a short tobacco seedling restitution stage, robust tobacco seedlings, simple and convenient transplanting and the like; and tobacco seedling utilization rate through the under-membrane transplanting method is improved, the seedling restitution stage is effectively shortened, tobacco plant survival is facilitated, and flue-cured tobacco economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of tobacco planting, in particular to a method for transplanting tobacco floating seedlings for uprooting and transplanting under film. Background technique [0002] At present, floating seedling raising technology is a technology commonly used in tobacco industry seedling raising. It refers to floating the foam tray equipped with light seedling raising substrate on the water surface, and sowing tobacco seeds in the substrate, so that tobacco seedlings can be grown on the seedling raising substrate. It can take root and grow in the medium, and can absorb water and nutrients from the substrate and water bed, so as to better realize the cultivation of tobacco seedlings. [0003] However, the tobacco floating seedling raising method in the prior art is limited by the hole size of the seedling tray, and the distance between the tobacco seedlings is too small, and there is competition for light, temperature, fert...
