Abstract
The strong sprout method of leaf-cutting is substituted in a kind of tobacco plant nursery of the present invention.In tobacco plant nursery, when tobacco seedlings it is long to tobacco stem 1-4cm high when, add last time nutrient solution, then first time foliage-spray is carried out, that is the Prohexadione calcium solution of the paclobutrazol solution of foliage-spray 20ppm-400ppm or 50ppm-400ppm cycocel solution or 20ppm-200ppm, nutrient solution is no longer added after spray, no longer leaf-cutting, it is suitable for the standard of transplanting when tobacco seedlings stem thickness root up to arrives strong sprout, second of foliage-spray is carried out again before tobacco seedlings transplanting, that is the ammonium nitrate solution of foliage-spray 3ppm-20ppm compound sodium nitrophenolate solution or mass fraction 0.1%-1%, then conventional transplanting is carried out.The present invention can inhibit tobacco seedlings to continue to grow tall, and promote stem length thick and root growth, to achieve the purpose that be not required to leaf-cutting and strong sprout to exempt leaf-cutting program exempts leaf-cutting equipment；It is artificial to exempt leaf-cutting；It reduces labor intensity；Shorten seedling raise period 15 days or more；Save nutritious fertilizer；The generation of the diseases such as virosis, fungi is reduced, tobacco seedlings are more healthy and stronger, and root system is more flourishing.
Description
Technical field:
The invention belongs to tobacco planting fields, and in particular to the strong sprout side of leaf-cutting is substituted in a kind of tobacco plant nursery
Method.
Background technique:
Tobacco is culturing and transplanting seedlings crop.Currently, tobacco business is promoting modern tobacco agriculture, tobacco seedling carries out factory
Change nursery, construction of modern Conjoined greenhouse, using floating seedlings or wet nursery, using sizing seedlings nursing plate, batch production preparation is educated
Seedling matrix, matrix carry out disinfection, control temperature and humidity, carry out leaf-cutting strong sprout, and educated tobacco seedlings are concentrated, quantity is more, neat, seedling quality
Height, breeding efficiency also greatly improve, and greatly advance the modernization of tobacco seedling production, improve production efficiency.But it is educating
Because density is closeer during seedling, tobacco seedlings long shoot comes into leaves, and tobacco seedlings are weaker, need to carry out leaf-cutting, and it is high that tobacco seedlings stem is controlled using leaf-cutting
Growth to promote stem thickness growth and strong sprout, leaf-cutting equipment need to be increased；Leaf-cutting again after the tobacco seedlings such as needing to grow tall after leaf-cutting, generally
It need to cut 3-4 times, it is artificial to increase leaf-cutting, enhances labor intensity, extends seedling raise period, wastes nutritious fertilizer；Especially exist
During leaf-cutting, leaf-cutting utensil and operation are very easy to the diseases such as transmitted virus disease, fungi, increase the occurrence probability of disease, pass through
The disease for often resulting in large area occurs.
Summary of the invention:
It does not need leaf-cutting the object of the present invention is to provide a kind of and substitutes the strong of leaf-cutting in the tobacco plant nursery of strong sprout
Seedling-growing method.
The strong sprout method of leaf-cutting is substituted in tobacco plant nursery of the invention, which comprises the following steps:
In tobacco plant nursery, when tobacco seedlings it is long to tobacco stem 1-4cm high when, add last time nutrient solution, then into
Row first time foliage-spray, the i.e. paclobutrazol solution of foliage-spray 20ppm-400ppm or 50ppm-400ppm cycocel solution or
The Prohexadione calcium solution of 20ppm-200ppm no longer adds nutrient solution, no longer leaf-cutting after spray, after 5 days when tobacco seedlings stem thickness root up to
It is suitable for the standard of transplanting to strong sprout, carries out second of foliage-spray, i.e. foliage-spray 3ppm-20ppm compound nitrophenol again before tobacco seedlings transplanting
Then the ammonium nitrate solution of sodium solution or mass fraction 0.1%-1% carries out conventional transplanting.
Above-mentioned nutrient solution is nutrient solution used in routine in tobacco plant nursery, belongs to the Conventional wisdom of this field,
Innovative point of the invention essentially consists in first time and second of foliage-spray.The formula of the nutrient solution is N:P:K=20:10:20
(in addition adding microelement in Ca, Mg, S etc.).
The plant growth retardents such as paclobutrazol, cycocel, Prohexadione calcium are to axis end Asia apical meristem cell or come into being
The cell division of meristematic cell has inhibiting effect, can inhibit the cell division and elongation growth of stem top lower area, can hinder
The biosynthesis of gibberellin, slows down growth rate, leads to plant shortened internodes, promotes the thickening and root growth of stem, but
Leaf size, lobe numbers, the number of section and apical dominance are not influenced, the formation of leaf, flower and fruit is not influenced.I.e.
By spraying the plant growth retardents such as paclobutrazol, cycocel, Prohexadione calcium, inhibits tobacco seedlings to continue to grow tall, and promote stem length
Thick and root growth, to achieve the purpose that be not required to leaf-cutting and strong sprout to exempt leaf-cutting program exempts leaf-cutting equipment；Exempt
Leaf-cutting is artificial；It reduces labor intensity；Shorten seedling raise period 15 days or more；Save nutritious fertilizer；Reduce the diseases such as virosis, fungi
Generation, tobacco seedlings are more healthy and stronger, and root system is more flourishing.
