Description

A kind of plant cultivation method

technical field

The invention belongs to the field of tobacco planting, and in particular relates to a plant cultivation method.

Background technique

Tobacco, belonging to Tubulariaceae, annual or limited perennial herb of Solanaceae, with slightly lignified base. Inflorescences terminal, paniculate, many-flowered; capsules ovate or oblong, about as long as persistent calyx. It blooms and bears fruit in summer and autumn. Mainly distributed in South America, South Asia and China.

However, the existing tobacco plants have poor economic performance and cannot meet the higher level of smoking quality needs of users. At the same time, there is still a low tobacco yield, which does not meet the needs of today's society for high-efficiency mass production.

Therefore, a production-increasing plant has been developed to solve the technical defects that the existing tobacco plants have poor economic performance and cannot meet the higher-level smoking quality requirements of users.

detailed description

The invention provides a plant cultivation method, which is used to solve the technical defects that the existing tobacco plants have poor performance in economic properties and cannot meet the higher-level smoking quality requirements of users.

The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

In order to describe the present invention in more detail, a plant cultivation method provided by the present invention will be specifically described below in conjunction with an embodiment.

Example 1

Determine the planting quality of parental tobacco plants according to the number of seed production. Generally, the planting density of the planting field is 1100-1300 plants/mu, and the ratio of parental tobacco plants is 1:2-4. The pollen of the male parent is collected at the full flowering stage and transferred to the female parent. On the stigma of the flowers, harvest the seeds when 80% of the capsules of the female inflorescence turn yellow or light brown, pick off the whole inflorescence and hang it in the air-seeding room for post-ripening, and after the seeds are dry, they are threshed to obtain the male sterile hybrid combination YK1085 Seed.

Using YA17-1 as the male parent and MSYB55 as the female parent, a male sterile hybrid combination YK1085 was prepared. Among them, YA17-1 belongs to Dicotyledonae, Picofloweres, Solanaceae, Nicotiana and Common Nicotiana in plant taxonomy. In plant taxonomy, MSK326 belongs to Dicotyledonae, Tubeflowers, Solanaceae, Nicotiana, and Nicotiana common species. At present, no new varieties bred with the same parents as the sterile hybrid combination YK1085 have been found in China. YK1085 has obvious differences from existing varieties (tobacco varieties that have been accepted or approved), with stable genetic traits, morphological characteristics and biological characteristics. unanimous.

Example 2

The average value of the first-generation male sterile hybrid combination YK1085 in the 2-year production area from 2013 to 2014 was measured. The yield of YK1085 mu was 186.04 kg, which was 28.73% higher than that of the control K326. The average price was 20.38 yuan/kg, which was 10.49% higher than that of the control K326. The average output value per mu was 3889.53 yuan, an increase of 44.04% compared with the control, the proportion of top-grade tobacco was 42.2%, an increase of 46.69% compared with the control, and the proportion of upper-medium tobacco was 76.7%, an increase of 10.26% compared with the control. Please refer to Table 1 for details.
