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 a rose family Fragaria perennial root perennial evergreen herbaceous plant, and the horticulture classification is gone up and belonged to berry tree.
Known Fragaria has 20 common kinds approximately, and modern cultivated strawberry kind all belongs to the pineapple strawberry, and the another name large fruited strawberry originates from the not natural crossing of state strawberry and Chilean strawberry of two America kinds.It is seedless that the strawberry berry does not have skin, and lovely luster is aesthetic in appearance; Tender succulence, sour and sweet palatability, fragranced is dense; Contain nutritive elements such as abundant vitamin C and phosphorus, calcium, iron, not only be of high nutritive value, also have medical care effect; Be a kind of suitable to people of all ages nourishing fruit, the good reputation of " fruit queen " is arranged.
20 beginnings of the century of pineapple strawberry are imported China into, begin after the founding of New to form certain planting scale, but slower development.Since the reform and opening-up, China's strawberry industry is flourish, becomes over nearly 20 years a new industry with fastest developing speed in China's fruit growing.At present all there is cultivated strawberry in China each province (city, district), with Donggang City, Liaoning, Hebei all over the city, Sichuan double fluid, Zhejiang Jiande, Changfeng, Anhui, Changping, Beijing etc. are the major production areas.From 2003, Chinese strawberry cultivating area, output began to surpass the U.S..National strawberry cultivating area was about 11.73 ten thousand hectares in 2010,2,000,000 tons of gross yields, and area and output all occupy first place in the world.The 7th world's strawberry conference on February 18th, 2012 successfully held in Changping, Beijing, advantageously promoted the fast development of strawberry science and technology with the industry of Beijing and China.
High-quality strong sprout is the basis of strawberry high yield and high quality; The quality of seedling directly influences strawberry output and quality; Common saying has the saying of " seven minutes in seedling, management in three fens ", the cultivated strawberry success or not, and key is to cultivate that flower bud differentiation is good, survival rate high strong sprout after the field planting.And the expansion of current China strawberry seedling numerous be main mainly with the open country land for growing field crops, the American-European kind that this seedling raising manners antagonism is strong is comparatively suitable, but to suitable eat raw, quality better, resistance is poor, reproduction rate is low Japanese kind is especially suitable; How thin and delicate the seedling that brings out is, and root system is few, and rhizome is thin; Flower bud differentiation is of poor quality, and death rate high (average 20%-40%) causes output minimizing, quality to reduce after the field planting; Directly influence the income and plantation confidence of certain kind of berries farming, 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 because the result of cross pollination can produce very big variation between the seedling, is difficult to keep the merit of former kind, generally only is used for breeding work.Propagation by division is that the new stem that has new root, new stem branch are separated with maternal plant with the biennial root-like stock that has adventive root; Become the method that independent plant is planted; The branching emergence rate is lower, adopts in the time of only need changing the ground replanting in the plantation or lack suitable seedling.Tissue culture propagating is to adopt stolon apical meristem (stem apex) and flower pesticide to carry out cultured in vitro, obtains the virus-free seedling of strawberry, 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 fit to have the scientific research department and the enterprise application of higher level and strong strength.Aborning; A large amount of stolon seedlings that the breeding of strawberry mainly utilizes maternal plant in process of growth, to produce 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 is so it is numerous all to adopt this method to expand in a large number in the actual production.
Stolon is a kind of special terrestrial stem that strawberry crawls to extend, 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 growth upwards, is downwarping subsequently, along the face of land to the strain clump less, sunshine good place extend.The big fruit pineapple of cultivated species strawberry take out living stolon all be in even number joint position give birth to the stolon seedling; The growing point of even number joint position is taken out the new stem of living cripetura; Adventive root takes place downwards in beginning before new the 3rd leaf of stem appears; When root touches wetland, just penetrate in the soil, form the sub-strain of the first generation (stolon seedling).The sub-strain of the first generation can be taken out living second generation stolon again, produces the sub-strain of the second generation, and the sub-strain of the second generation can be taken out living third generation stolon again, 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 the stolon branch.Every stolon can grow stolon seedling 3-5.
What of stolon take place in each plant in 1 year, with kind and external condition substantial connection is arranged.3-5 strain of generation can take place 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 the 100-200 strain.General American-European kind stolon generation quantity is more in kind, and Japanese article speciogenesis negligible amounts, some kind is merely the 10-20 strain.
After maternal plant was taken out living a large amount of stolons, more extensive management method was to let alone freely to grow at present, takes root at random; Comparatively meticulous management is that manual work is controlled each bar stem evenly on the vacant lot of maternal plant both sides; And training nutrition soil pressure is climing on the joint position of giving birth to seedling, is beneficial to seedling and takes root growth, is configured by the space simultaneously; Avoid overlapping, the intersection of each stem, influence seedling and evenly grow.
During the strawberry conventional seedbed system was produced, how the stolon seedling directly took root in the soil in peripheral seedbed that with the maternal plant is the center, is that the center radially distributes with the maternal plant, and the seedling seedling age far away more apart from maternal plant is more little.This seedling grew in the rain 7-8 month of the hot same period more, was prone to multiple diseases such as excessive growth and infection anthrax, and the seedling that breeds out is many and thin and delicate, flower bud differentiation is of poor quality.Just can play transplantation of seedlings when the strawberry seedling reaches certain seedling age, water earlier during lifting permeable, if field planting nearby; Preferably balled transplanting if need long-distance transportation, then can not be with soil more; After Lao Ye and stolon etc. cut, tie into wisp by kind, size fractionation, this seedling is called bareroot seedling.Because bareroot seedling will hurt root system inevitably in lifting and transportation, root system is exposed in the air behind the lifting, and mismanagement very easily causes root system dehydration phenomenon; This bareroot seedling of field planting often needs big slow seedling, and survival rate is on average only at 50%-70%; Need repeatedly to fill the gaps with seedlings in large quantities, the seedling behind the slow seedling is differed in size, the growing way difference is very big, brings inconvenience and trouble to unified management; Fill the gaps with seedlings and plant back management and also expended cost of labor in a large number, obviously 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 changing open country into facility, change soil into matrix, the level land is changed into overhead etc.Also introduce on the container for plant growth and when having utilized vegetable crop to grow seedlings polypots commonly used, porous cave dish etc. grow seedlings; Also obtain certain effect; But in application process, also exist can not satisfy seedling development, can't evenly water, problems such as operational administrative inconvenience, therefore need exploitation badly and be fit to the special-purpose container for plant growth that strawberry is grown seedlings.
