Abstract

The invention discloses an artificial breeding method for tomato seeds. The method comprises the steps of tomato seed preparation, tomato seed soaking for pretreatment, tomato seed pharmaceutical treatment, tomato seed disinfection, tomato seed germination accelerating and tomato seed sowing. Compared with the prior art of tomato seedling raising, the seed germination percentage in the artificial breeding method is 96-98%, the seedling transplanting survival rate is 90-93.5%, cultured seedlings are strong in growth vigor, developed in root system and high in disease resistance, the incidence rate of gray mold, bacterial wilt and leaf mold is obviously lowered during culturing, the adaptability is high after transplanting, the flower rate and fruit setting rate of tomatoes are significantly improved, fruit development is good, and fruit flesh quality is good.

Description

The artificial raise seedling method of a kind of tomato seeds

Technical field

The present invention relates to field of planting, particularly relate to the artificial raise seedling method of a kind of tomato seeds.

Background technology

Tomato is that Solanaceae belongs to herbaceous plant, comprises determinate growth, half determinate growth and one dimensional infinite wall. Condition can grow time suitable for many years. It is various in style, vegetative period is long, is loved by the people, and becomes one of main raise crop of the main vegetable crop of warmhouse booth and winter-spring season. The tomato seeds percentage of germination of order existing planting technology plantation is low, kind shoot survival percent is low, thus can improve production cost.

Summary of the invention

In order to overcome above-mentioned deficiency, the present invention provides the artificial raise seedling method of a kind of tomato seeds.

The present invention is achieved through the following technical solutions:

An artificial raise seedling method for tomato seeds, comprising:

1) preparation of tomato seeds: select natural maturity, healthy and strong tomato seeds to be used for nursery;

2) dipping pretreatment of tomato seeds: at tomato seeds is put into 30-35 DEG C mass percent be 1.5% sodium hydrogen carbonate solution soak 1 hour, it is possible to break the dormancy of seed to a certain extent, promote the permeability of seed coat, then take out, drain;

3) chemicals treatment of tomato seeds: utilize medicament to soak tomato seeds 4-6 hour, described medicament is by mass percentage by 2% sodium-chlor, 0.1% paddy skin myron liquid, 1.5% sucrose, 0.01% potassium permanganate, all the other are clear water composition, each interaction between component, seed dormancy can be broken further, improve the permeability of seed coat, seed coat can be played the effect of shallow virus killing, and the growth of embryo can be promoted;

4) tomato seeds sterilization: above-mentioned tomato seeds adopts potassium permanganate, 6% sodium-chlor and the 1% sodium hydroxide mixing solutions of 0.2% carry out immersion treatment, treatment time is 10 minutes, can alleviating and control the disease of some common virus diseases, bacterium one class, especially gray mold, bacterial wilt, leaf mold sickness rate obviously reduce;

5) tomato seeds vernalization: tomato seeds is placed in culture dish, vernalization 20 hours under the envrionment temperature of 28-35 DEG C, when 15th hour, adopts the magnetic field treatment of change, to more than 95% tomato seeds shows money or valuables one carries unintentionally to seed, the magnetic field of described change, the scope of change of magnetic field strength at 0-45mT, when magneticstrength is 0, starting every 5s increases progressively once, each incremental change is than last many 1mT, and first 5s magneticstrength increasing amount is 1mT, until magneticstrength is increased to 45mT, and then, starting every 5s successively decreases once, and each decrement is than last many 1mT, and first 5s magneticstrength reduction is 1mT, until magneticstrength reduces to 0, follow-up circulate successively, in the magnetic field treatment starting to adopt change for 15 hours of vernalization, the activity of various enzyme in enzymatic reaction can be promoted, strengthen the breathing of cell further, accelerate seed absorbing nutritive substance, and each increasing amount of magneticstrength is increased to 9 from 1, when magnetic field increases, magneticstrength is changed in the way of becoming acceleration, when magnetic field reduces, magnetic field is changed in the way of becoming deceleration, can effectively regulate the cell cycle of the corresponding cell of tomato seeds, promote cell fission, and the fruit-setting rate after tomato seeds can being developed into plant promotes has great promoter action,

6) tomato seeds sowing: the tomato seeds showed money or valuables one carries unintentionally is sowed.

The invention has the beneficial effects as follows: compared with existing tomato seedling technology, the present invention has extremely significant advantage, technique scheme is adopted to carry out tomato seeds nursery, rate of emergence is at 96%-98%, seedling replanting surviving rate is at 90%-93.5%, the seedling cultivated, growth potential is strong, well developed root system, and disease resistance is strong, nurturing period gray mold, bacterial wilt, leaf mold sickness rate obviously reduce, transplant after strong adaptability, and the flowering rate fruit-setting rate of tomato all tool increase significantly, fruit development is good, the content of vitamin A obviously increases, and meat quality is good.

Embodiment

An artificial raise seedling method for tomato seeds, comprising:

4) tomato seeds sterilization: above-mentioned tomato seeds adopts potassium permanganate, 6% sodium-chlor and the 1% sodium hydroxide mixing solutions of 0.2% carry out immersion treatment, and the treatment time is 10 minutes, it is possible to alleviate and control the disease of some common virus diseases, bacterium one class;

Adopting technique scheme to carry out tomato seeds nursery, rate of emergence is at 96%-98%, and seedling replanting surviving rate is at 90%-93.5%.
