Abstract

The invention discloses a treatment method for achieving high germination rate of tomato seeds. The method comprises the steps that the seeds are selected and air-dried to make the water content below 7 percent, flat seeds are removed, and the selected seeds are put into a drying oven to be baked for sterilization and disease prevention; the seeds are put in hot water for soaking, stirring is conducted during soaking, after seed husk mucus is washed through clear water, the soaked seeds are taken out, water control is conducted, and then the seeds are dried in the air; freezing treatment is conducted on the air-dried seeds, and then the seeds are packed in sacks to be in a loose state; stone and sand are added into a wicker basket, the sacks filled with the seeds are put into the wicker basket, then one layer of sand and one layer of the sack are stacked, the filled wicker basket is placed in a shade place, the treated seeds are watered with a nutrient solution once in every day morning, the seeds can be revealed after three days, and pregermination is completed. By means of the treatment method for achieving the high germination rate of the tomato seeds, bacteria carried by the seeds are reduced, the disease resistance is enhanced, seedlings can develop rapidly and be robust, the bud ratio is guaranteed, the situation that the seeds are rotten and wasted due to fact that partial seeds do not bud when direct seeding is conducted is prevented.

Description

A kind of tamato seed high germination rate processing method

Technical field

What the present invention relates to is field of agricultural cultivation, and what be specifically related to is a kind of tamato seed high germination rate processing method.

Background technology

Along with the development trend in market, in agricultural planting industry, improve for making vegetable grower's production imcome, agricultural product are allowed to carry out market in advance, and bring income, first just do from nursery, for promoting that seed sprouting is fast, pre-preventing disease and pest, strengthen rice shoot resistance and enhancing development, just to seed treatment before sowing, under normal circumstances, seed is directly sowed in ground, ground, sprout so slow, bud ratio is low, and the seedling quality sprouted is uneven, weak seedling is many, in process of growth afterwards, easy ill insect pest, difficulty is brought to field management, also add production cost, differ in the maturity in maturing stage, cause the prolongation of harvest time, be unfavorable for the plantation of lower first phase, thus reduce the problems such as income.

Summary of the invention

In order to solve above-mentioned run into problem, spy discloses the present invention.

A kind of tamato seed high germination rate processing method, comprises the following steps:

(1) select improved seeds and airing seed, make water content below 7%, the baking oven putting into 70 ~ 73 DEG C toasts 2min, is then placed in water by tamato seed, rejects the flat seed of bubbling through the water column and the low seed of quality;

(2) be placed on by seed in the hot water of 55 ~ 60 DEG C and soak 10 ~ 15 minutes, immersion limit, limit is stirred, and when water temperature is down to 30 DEG C, stops stirring, continues immersion 3 ~ 4 hours, after washing away seed coat mucus, takes out control water with clear water, and it is air-dry to put shady and cool place;

(3) by the tamato seed after air-dry, be placed on freezing 24h in refrigerator, temperature is set as-2-0 DEG C;

(4) be contained in flax silk bag by the tamato seed after freezing, every bag of band 0-2.5kg, treats vernalization;

(5) bottom pad paving stone in flat wicker basket, at covering one deck sand on it, then one deck packed tamato seed one deck sand, is put in shady and cool place's vernalization, every morning, irrigates one time of nutrition liquid, carry out vernalization; Described nutrient solution is the mixed liquor of gibberellin 300 times of liquid, Fluoxastrobin 200 times of liquid, brassin 500 times of liquid, a-Nafusaku 100 times of liquid, zeatin 400 times of liquid, amino-oligosaccharide 300 times of liquid 2:1:1:3:2:1 by volume.

Further, the gauze bag described in step (4) is the flax silk bag keeping flat size 30X50cm, limit mouth discontinuous edge sealing.

Beneficial effect of the present invention: tamato seed is nursery or live again after vernalization process, not only tomato seedling goes out together, looks strong, and growing way is well-balanced, there will not be the situation that tomato seedling is not of uniform size, precocious 5-7 days, the every mu volume increase 200-300kg of tomato can be promoted compared with live with routine, ensure that maturing stage uniformity, the invasion of damage by disease and insect can also be resisted.

Embodiment
