Description
Technical field
The present invention relates to a kind of strawberry seedling culture hole plate, be applicable to the numerous production of expansion of strawberry stolon seedling.
Background technology
Strawberry is rose family Fragaria perennial root perennial evergreen herbaceous plant, the upper berry tree that belongs to of horticulture classification.
Known Fragaria approximately has 20 Common Species, and modern cultivated strawberry kind all belongs to pineapple strawberry, calls large fruited strawberry, originates from the natural crossing of two America Zhong Fu state strawberries and Chilean strawberry.Strawberry berry is seedless without skin, bright in colour, aesthetic in appearance, tender succulence, sour and sweet palatability, fragranced is dense, contain the nutritive elements such as abundant vitamin C and phosphorus, calcium, iron, be not only of high nutritive value, also there is medical care effect, be a kind of suitable to people of all ages nourishing fruit, have the good reputation of " fruit queen ".
20 beginnings of the century of pineapple strawberry are imported China into, after founding of New, start to form certain planting scale, but slower development.Since reform and opening-up, China's Strawberry industry is flourish, becomes a new industry with fastest developing speed in Jin20Nian Lai China fruit growing.At present all there is cultivated strawberry in China each province (city, district), taking Liaoning Donggang City, Hebei all over the city, Sichuan double fluid, Jiande in Zhejiang, Changfeng, Anhui, Changping County, Beijing etc. are as major production areas.From 2003, Chinese Strawberry Industry cultivated area, output started to exceed the U.S..Approximately 11.73 ten thousand hectares of national strawberry cultivating areas in 2010,2,000,000 tons of gross yields, area and output all occupy first place in the world.18 Qi Jie worlds strawberry conference February in 2012 is successfully held at Changping County, Beijing, has advantageously promoted the fast development of the strawberry science technology and industry of Beijing and China.
High-quality strong sprout is the basis of strawberry high yield and high quality, the quality of seedling directly affects Yield of Strawberry and quality, common saying has the saying of " seven points in seedling, three points of management ", cultivated strawberry success or not, and key is to cultivate that flower bud differentiation is good, survival rate high strong sprout after field planting.And the expansion of current China strawberry seedling is numerous mainly taking open country land for growing field crops as main, the American-European kind that this seedling raising manners antagonism is strong is comparatively applicable, but the Japanese kind of suitablely eating raw, quality is better, resistance is poor, reproduction rate is low is especially not suitable for, and how thin and delicate the seedling bringing out is, and root system is few, rhizome is thin, flower bud differentiation is of poor quality, and after field planting, death rate high (average 20%-40%), causes output minimizing, quality to reduce, the income and the plantation confidence that directly affect certain kind of berries agriculture, restricted the development of Strawberry industry.
The breeding of strawberry, has four kinds of seminal propagation, propagation by division, stolon breeding and tissue culture propagatings.Strawberry can utilize seed to carry out seed propagation, but due to the result of cross pollination, between seedling, can produce very large variation, is difficult to keep the merit of former kind, general only for breeding work.Propagation by division is that the new stem with new root, new stem branch are separated with maternal plant with the biennial root-like stock with adventive root, become the method that independent plant is planted, branching emergence rate is lower, when only need changing ground replanting in plantation or lacking suitable seedling, adopts.Tissue culture propagating is to adopt stolon apical meristem (stem apex) and flower pesticide to carry out cultured in vitro, obtains strawberry virus-free seedling, is mainly used in seedling detoxification and new varieties more.Tissue culture propagating speed is fast, can carry out batch production production, but to operating equipment and environmental requirement high, technical strong, have a big risk, be applicable to having scientific research department and enterprise's application of higher level and stronger strength.Aborning, the breeding of strawberry mainly utilizes a large amount of stolon seedlings that maternal plant produces in process of growth to carry out vegetative propagation, the characteristic that this method is simple to operate, reproduction coefficient is high, be easy to get seedling, can keep kind, so it is numerous all to adopt this method to carry out a large amount of expansions in actual production.
Stolon is the strawberry a kind of special terrestrial stem of extending that crawls, and is the main organ of multiplication of strawberry, and stem is thin, soft, internode is long, axillary bud sprouting by new stem forms, nascent is upwards grown, be bent downwardly subsequently, along earth's surface to strain clump less, sunshine good place extend.The stolon of the large fruit pineapple of cultivated species strawberry pumping be all in even number joint position raw stolon seedling, the new stem of growing point pumping cripetura of even number joint position, before appearing, new the 3rd leaf of stem start to occur adventive root downwards, in the time that root touches wetland, just penetrate in soil, form the sub-strain of the first generation (stolon seedling).The sub-strain of the first generation again can pumping second generation stolon, produces the sub-strain of the second generation, and the sub-strain of the second generation again can pumping third generation stolon, produces the sub-strain of the third generation.The rest may be inferred, can form many for stolon and the sub-strain of Duo Dai.Odd number joint position does not produce sub-strain, and axillalry bud keeps dormancy or produces stolon branch.Every stolon can grow stolon seedling 3-5.
There is the number of stolon in each plant, has substantial connection with kind and external condition in 1 year.Can there is 3-5 strain of generation in general northern area 1 strain maternal plant, and southern area can reach 10-12 generation, the about 30-85 strain of total sub-strain number, and many persons can reach 100-200 strain.In kind, general American-European kind stolon generation quantity is more, and Japanese product speciogenesis negligible amounts, some kind is only 10-20 strain.
When after a large amount of stolons of maternal plant pumping, more extensive management method is to let alone free growth at present, take root at random, comparatively meticulous management is manually each stem to be controlled evenly on the vacant lot of maternal plant both sides, and on the joint position of raw seedling, train Nutrition Soil and keep down the vines of a creeping plant, be beneficial to seedling and take root growth, be configured by space simultaneously, avoid each stem overlapping, intersect, affect seedling and evenly grow.
During strawberry conventional seedbed system is produced, how stolon seedling directly takes root in the soil in the periphery seedbed centered by maternal plant, centered by maternal plant, radially distributes, and the seedling seedling age far away apart from maternal plant is less.This seedling grew in the rain heat 7-8 month of the same period more, the easily multiple diseases such as excessive growth and infection anthrax, and the seedling breeding out is many and thin and delicate, flower bud differentiation is of poor quality.Just can play transplantation of seedlings when Strawberry seedlings reaches certain seedling age, when lifting, first water permeable, if field planting nearby, preferably balled transplanting, if need long-distance transportation, can not multi-band soil, after Lao Ye and stolon etc. are cut, be bundled into wisp by kind, size fractionation, this seedling is called bareroot seedling.Because bareroot seedling inevitably will hurt root system in lifting and transportation, after lifting, root system is exposed in air, mismanagement very easily causes root system dehydration phenomenon, and this bareroot seedling of field planting, often needs to delay greatly seedling, survival rate is on average only at 50%-70%, need repeatedly to fill the gaps with seedlings in large quantities, the seedling after slow seedling is differed in size, growing way difference is very large, brings inconvenience and trouble to unified management, fill the gaps with seedlings and plant rear management and also expended in a large number cost of labor, obviously having reduced the economic benefit of plantation.
For a change open country is bred the shortcoming of bareroot seedling, and people also attempt improving seedling-cultivating method from many aspects, as changed open country into facility, change soil into matrix, level land are changed into overhead etc.Also polypots, porous cave dish etc. conventional when introducing on container for plant growth and having utilized vegetable crop to grow seedlings are grown seedlings, also obtain certain effect, but in application process, also exist can not meet seedling development, cannot evenly water, the problems such as operational administrative inconvenience, therefore need exploitation badly and be applicable to the special container for plant growth that strawberry is grown seedlings.
