Abstract

The present invention discloses a kind of greenhouse youth-and-old-age cultivation technique, belongs to technical field of crop cultivation.The specific steps that the technology includes have：Sowing, pinching, illumination management, blooming period management.Greenhouse youth-and-old-age cultivation technique is standardized, become more meticulous by the present invention, is advantageous to improve its yield and is increased farmers' income.

Description

A kind of greenhouse youth-and-old-age cultivation technique

Technical field

The invention belongs to technical field of crop cultivation, and in particular to a kind of greenhouse youth-and-old-age cultivation technique.

Background technology

Youth-and-old-age flowers implied meaning is misses remote friends, and year in and year out, the youth-and-old-age florescence is very long, from June to September, flower Open successively, keep gay colours for a long time, signify Auld Lang Syne, the flowers are in blossom for youth-and-old-age first on top, then side shoot Top bloom it is higher than what first was opened, so name " Bubukao " again.Wide market, it is the good of peasant programme One of good approach.

The content of the invention

The technical problems to be solved by the invention are the deficiencies for existing greenhouse youth-and-old-age cultivation technique, there is provided greenhouse hundred Day careless cultivation technique, be advantageous to improve its yield and increase farmers' income.

To achieve these goals, the present invention is achieved using following technical scheme：

A kind of greenhouse youth-and-old-age cultivation technique, including following specific steps：

1. sowing:Youth-and-old-age, also can cutting propagation based on seminal propagation.It is general to sow in early April to late June, Seed disinfection is soaked seed 30 minutes with 1% potassium permanganate liquid, and 2 parts of leaf mould of matrix, 1 part of river sand, 2 parts of peat, 2 parts of perlite are mixed Conjunction is formulated, and can be sterilized with 0.05% potassium permanganate or 1000 times of formaldehyde, soil can use high temperature fumigation method, kill therein Germ, insect and grass seeds.Its seed tool dislikes photosensitiveness, after planting answers earthing, watering, moisturizing, can germinate within about 2-5 days.Germination For rate typically 60% or so, germination thermophilic is 22-25 DEG C.Youth-and-old-age growth is exceedingly fast, easy excessive growth, so wanting timely pinching, promotees Axillary bud growth is sent out, makes it spend strain sturdy, seat flower rate is high.Youth-and-old-age avoids continuous cropping, answers in good time crop rotation.

2. pinching:Short raw youth-and-old-age wants multiple pinching, for the first time in 6 leaf, stays 4 leaf pinching, altogether pinching 2-3 times, often Potassium dihydrogen phosphate is applied after secondary pinching, particularly buddings to blooming, often to spray within 5-7 days 0.2% potassium dihydrogen phosphate.Fertilising is anti- Disease.After plant strain growth is stable, ground moistening should be kept, summer respectively pours a water sooner or later, and Seedling Stage was applied one time 200 every 5-7 days The nitrogenous fertilizer and organic fertilizer of mg/litre, use composite fertilizer after applying 2-3 times instead, season in midsummer preferably applies thin fertilizer, with fertile Dai Shui.

3. illumination management:Youth-and-old-age growth potential is strong, likes warm, dry and sun-drenched environment, and it is cloudy to be also resistant to half.Growth Thermophilic is 20-25 DEG C, not heat-resistant, and when temperature is higher than 35 DEG C, growing way substantially weakens, and rareness of blooming, flower are also smaller.For Short-day plant, under the long-day (hour/day of illumination 14), blooming to postpone, and taken around 70 days from being seeded into bloom, this When ligulate flower can showed increased；Under short-day (hour/day of illumination 9), only needed 60 days from being seeded into bloom, flower now is then It is more with tubular flower.Strong adaptability, does not select soil, but soil layer is deep, it is optimal to be grown in well-drained fertile soil.It is more in summer In the case that rain or drainage of soil are bad, plant is elongated, flower diminishes.

4. blooming period management:10-12 centimetres of basin is colonized in during tree seedling 4-6 piece leaves.Zinnia lateral root is few, pays attention to during transplanting few Hinder lateral root.During 10 centimetres of height of seedling, pinching is carried out, promotes more points of side shoots.For dwarfed plant in production, 2 weeks after pinching, use 0.5% alar-85 is sprayed, significant effect.Also regulation florescence, Seedling Stage 0.25%-0.4% alar-85s can be come using growth regulator Spray solution, can Blooming, flower is close；0.4%-0.8% alar-85s or cycocel are such as used, sprays 2-4 times, postponement is bloomed.Open More top dressings (chemical fertilizer, decomposed manure etc.) before spending, general 5-7 days once, until blooming.In time by residual flower from scape base portion after spending (staying 2 pairs of leaves) cuts off, top dressing 2-3 times after trimming, ensures the liquid manure needed for plant strain growth, to extend the overall florescence.Youth-and-old-age is not Heat-resistant, rare, the less phenomenon of flower of blooming occurs in people's August of spouting, and need to strengthen irrigating, and prevents and treats red spider.So can to September Normally bloom, be solid.
