Description
Technical field
The present invention relates to artichoke technical field of cultivation, be specifically related to a kind of artichoke floating seedlings culturing method.
Background technology
Artichoke is one draft perennial plant for many years during composite family cynara scolymus belongs to, and originates in Mediterranean.In natural situation, a local strain artichoke can be survived the more than ten years.In production, local farmer upgrades once for general 3 ~ 5 years.In China, artichoke mostly is annual cultivation, and the overwhelming majority is all use seed seedling-raising.Due to weather, artichoke can be bloomed in China but can not be solid, and annual seed all needs import, expensive, and seedling cost is high.And artichoke seed is achene, its kind of skin depth and hard, nursery is more difficult again.This just makes artichoke seedling growing process become a bottleneck problem of this industry development.
The reason of artichoke nursery difficulty has the following aspects:
1. temperature is suitable not: China starts sowing September, and now temperature is substantially more than 30 DEG C,
And the preference temperature of artichoke seed sprouting is 25 DEG C, so its germination requirement not too suitable under natural conditions, facility cultivation should be used.
2. germination rate is low: hard because of its kind of skin depth, water absorbing capacity is poor, and seed is difficult to sprout.And seed soaking is urged
After bud, its vigor can be affected again.
3. emerge irregular: the only need of emerging the earliest 7 days, the need of emerging late 25 days, front and back difference is larger.
4. transplanting survival rate is low: the leaf of Ji seedling is comparatively large, and easy dehydration, transplanting survival rate is low.
5. easily susceptible: seedling stage is easy to susceptible, as downy mildew, damping off etc.
At present, China mainly contains three kinds for the seedling growing process of artichoke: cultivation, plug media nursery and feeding block seedlings raising are directly sowed in vernalization.But no matter be live by presoaking and germinating or plug media nursery, emergence rate is all very low, emerges also uneven.And although feeding block seedlings raising technology emergence rate can reach 70 ~ 75%, effort of taking a lot of work, complex operation, labor cost is high.Seedling-growing time long (sow neat seedling time about need 15 ~ 20 days), emerges uneven.Punching is also needed during transplanting.Nutritive cube weighs again, transplants inconvenient.Nutritive cube has cut off main root and more root system when transplanting, and making artichoke by axial root system crop people for becoming system of fibrous root crop, have impact on root system development and plant strain growth.
