Coil without native cuttage and seedling culture method in cave, a kind of gardenia rice fieldTechnical field
The present invention relates to nursery technology field, relate in particular to cave, a kind of gardenia rice field and coil without native cuttage and seedling culture method.
Background technology
Cape jasmine (Gardenia jasminoides Ellis), being the evergreen dwarfing shrub of Rubiaceae Gardenia Ellis, is good Landscape Trees, is also important potted flower and cut-flower, cape jasmine is also important traditional Chinese medicine simultaneously, needs to breed a large amount of nursery stocks in production.
Cape jasmine propagation method has the breeding of growing directly from seeds, division propagation, propagation by layering, tissue cultivation and cottage propagation etc.
The breeding of growing directly from seeds can not keep maternal merit, adopts press strip and division propagation, and reproduction coefficient is low.Though tissue cultivate can breed in enormous quantities the seedling cycle long, technology requires high relatively.
Water cutting method is taken root soon than the slotting method of soil, and without soil-borne disease, in cape jasmine breeding, application is general.Traditional method has water tank to insert and a bottle water cutting, and south is general compiles a circular basket or case with reed bar or bamboo, at the bottom of the cuttings of cape jasmine is inserted in basket, swims in the clean water surface, gives free rein to take root; The north is placed on cuttings in the vial of water storage summer, is placed under sunlight, needs duty to change water, rinses blade and temperature and humidity control etc.Current also useful cystosepiment does supporter water cutting breeding gardenia, floats on indoor container and the surface of open water.But water planting cuttage at present not yet on a large scale for the production of.
The hard branch of in July, 2000 (Zhong Xiulin) clip in the middle ten days cape jasmine, the long 10-20cm of its trunk, stay the 5-6 of branch, insert in the rice field of vigorous growth, on branch, original blade is not extractd or removes in right amount, and the cuttage degree of depth is 5-8cm, can form the cape jasmine seedlings with 21 roots, but cuttings limited amount system, excavates nursery stock inconvenience, affects paddy rice harvesting.
Summary of the invention
The invention provides cave, a kind of gardenia rice field coils without native cuttage and seedling culture method.
The technical scheme that the present invention takes is:
Cave, gardenia of the present invention rice field dish is as follows without the concrete steps of native cuttage and seedling culture method:
(1) rice planting: the wide 90-120cm of paddy rice furrow, length is not limit, spacing 40-60cm between furrow, the reserved cave dish of placing in vacant lot between furrow; Adopt the seeding row spacing of peasant household's custom use in rice transplanting in the first tenday period of a month in May.
(2) cuttings is chosen: in the 7-8 month, on the good cape jasmine female parent without damage by disease and insect, choose the vigorous growth semi-lignified young sprout of a year with 3 joints, long 10-15cm, cut sth. askew in lower end, otch is level and smooth, retains young sprout upper end two and saves blade (5-6 sheet leaf);
(3) cuttings processing: the cape jasmine cutting of having pruned is rinsed well with clean water, the branch base portion 2-5cm 800mgL that submerges after draining away the water-1indolebutyric acid solution in dip 2-3 second;
(4) cottage method: pack cutting medium into 72 Confucian Garden wood caves dishes, matrix is from rim, cave mouth 0.5cm, every hole one strain cuttings, cuttage degree of depth 3cm, is placed on after cuttage is complete between paddy rice furrow on vacant lot;
(5) cuttage management: guarantee rice field depth of water 2-5cm after cuttage in month, owing to there being certain nutrient in paddy field water either, without the foliar application of normal cutting propagation, after three weeks, cuttings otch starts healing and taking root, survival rate generally can reach more than 98%, transplants or further cultivate nursery stock before rice harvest.
In step (1), the wide 100cm of paddy rice furrow, spacing 50cm between furrow.
In step (2), the long 12cm of semi-lignified young sprout.
In step (3), the branch base portion 3cm 800mgL that submerges-1indolebutyric acid solution.
In step (4), cutting medium is peat and perlite, and both weight ratios are 1: 1.
In step (5), after cuttage, in one month, guarantee rice field depth of water 3cm.
The present invention adopts rice field without the cuttage of soil pit dish, air humidity more than 80% between reserved paddy rice furrow during cuttage rooting, and 25～30 ℃ of temperature, light transmittance 10-30%, is applicable to cuttage rooting.
The dish cuttage of cave, rice field is carried out photosynthesis than the blade of the many reservations of conventional method, and cuttage in summer this season can form more than 20 nursery stock of root system.Without building booth, building sunshade net, and save the area, without often water spray moisturizing, without intertill and clean tillage etc., simple and convenient management also can amount reproduction.
This method adopts soilless substrate, and disease is few, and the nursery stock of breeding can be used for hydroponic flowers, also can transplant basin or ground cultivation.Transplanting hole tray seedling is not hindered root simultaneously, and without seedling-slowing stage, survival rate is high, grows vigorous.
Good effect of the present invention is as follows:
The present invention adopts rice field without the cuttage of soil pit dish, and in the ranks air humidity is more than 80% for reserved paddy rice, and blade can be not wilting because of dehydration, light transmittance 10-30%, and band leaf as much as possible can carry out photosynthetic, and cuttage in summer this season can form 20 above nursery stocks of root system.
This method adopts soilless substrate, and disease is few, and the nursery stock of breeding can be used for hydroponic flowers, also can transplant basin or ground cultivation.Without building booth, building sunshade net, without often water spray moisturizing, without intertill and clean tillage etc., simple and convenient management also can amount reproduction.Utilize space between paddy rice furrow, cultivate nursery stock, the cycle is short, and about two wheat harvesting periods, do not affect rice yield, saves the area, can mass breeding.
Embodiment
The following examples are to describe in further detail of the present invention.
Embodiment 1
