A tobacco cultivation method combining semi-dry bed seedling raising with warm hole transplanting

Abstract

The invention provides a tobacco planting method combining half-dry land bed seedling and transplanting. The tobacco planting method comprises the two processes of half-dry land bed seedling and warm-hole type transplanting, wherein the half-dry land bed seedling and warm-hole type transplanting comprises the steps of fertilizing, ridging, tobacco-hole excavating, open-water transplanting, drug-spraying around the root of the tobacco, in-time film mulching, trepanning and ventilating, seedling drawing out and small-size ridge plowing and film uncovering and large-size ridge plowing. The tobacco planting method has the advantages that the problem that the tobacco seedling is delicate and not strong during the transplanting process is solved, the survival rate of transplanting is improved, the seedling recovering period is shortened, and the seedling cost is reduced, and a warm small space for the grooving of the tobacco seedling is created, so that the influence of low temperature and drought is avoided; premature and fast-growing of the tobacco seedling are facilitated, early blossoming of the tobacco seedling is prevented, deep cultivating can be realized thoroughly, flourishing root system of a tobacco plant is promoted, the drought-enduring capability of the tobacco plant is strengthened, occurring of viral disease is reduced, labor concentrating problem during the tobacco seedling transplanting period is also relieved, and the transplanting time can be advanced according to the local tobacco production status. The tobacco planting method combining half-dry land bed seedling and transplanting is suitable for the tobacco cultivation such as the flue-cured tobacco, the burley tobacco and the sun-cured tobacco.

Description

technical field [0001] The invention belongs to the technical field of tobacco cultivation, and in particular relates to a tobacco cultivation method combining semi-dry bed seedling cultivation with warm hole transplanting. Background technique [0002] Transplanting method is a key link in tobacco production, which is related to the yield and quality of tobacco leaves. Since the development of flue-cured tobacco seedling cultivation and transplanting technology, the use of greenhouse floating seedling cultivation technology to cultivate high-stem and strong seedlings and realize high-ridge deep planting has been widely recognized; flue-cured tobacco mulching cultivation has also formed a relatively complete technical system. The fertilizer effect played a positive role in the production of high-quality flue-cured tobacco. With the development of social economy and production in tobacco-growing areas, many tobacco-growing areas have encountered technical bottlenecks in actu...

Problems solved by technology

The previous transplanting technology can no longer meet the needs of the new situation, for this reason, the research and development of new transplanting technology is particularly necessary

In recent years, some new technologies have emerged in flue-cured tobacco transplanting. For example, Chinese patent 201110203197.5 discloses a method for transplanting flue-cured tobacco mulch-filmed well cellar seedlings. Although this method can shorten the seedling period after transplanting in tobacco leaf production practice , Scattered transplanting season labor, but did not solve the quality problem of tobacco seedlings, tobacco seedlings were transplanted directly without cutting leaves and hardening, resulting in weak and slow growth of seedlings, more seedlings, and irregular growth, especially in high mountain areas; In addition, this method has high requirements on the moisture content of the ridge body when making the transplanting well cellar, and it is easy to cause the hole wall to be smooth and destroy the soil structure around the smoke hole. It is conducive to the rapid rooting of tobacco seedlings, even rotten roots and dead seedlings, and it is easy to breed wild slugs, especially on flat land and sticky soil. The risk of freezing and frost, early flowering is more serious in some fields

Guo Hanhua and others reported a method of deep planting of flue-cured tobacco in the periodical "Crop Research" 2005 No. 1 article "Research on the Influence of Large Hole Deep Planting of Flue-cured Tobacco on Field Microclimate and Growth Period", although this method can be used in production practice. Defend against low temperature hazards and achieve early transplanting. However, due to the use of conventional tobacco seedlings and the need to arch the top of the hole with bamboo sticks, there is not much room for the growth of tobacco seedlings under the film, and the time for tobacco seedlings to stay under the film is relatively short, and the resistance to stress is limited. , and it is necessary to grab moisture before planting and cover with film, which is troublesome to operate and labor-intensive

Wang Xijin and others reported a technique of transplanting flue-cured tobacco seedlings under film in the journal "Modern Agricultural Science and Technology" in the first issue of 2014. Although this method can shorten the In the seedling raising stage, the cost of raising seedlings can be reduced, but it cannot solve the problems of weak quality of tobacco seedlings when transplanting, low survival rate of transplanting and long seedling return period. Moreover, because the tobacco seedlings are not planted in large holes, the growth space of the tobacco seedlings under the film is small and the tobacco seedlings The longest time for seedlings to stay under the film is only 8 days, the ability to resist stress is not strong, and they need to grab moisture for transplanting
