Abstract
The invention relates to a method for enhancing germination rate of cocksfoot seeds. According to the invention, a penicillin solution is utilized to carry out seed soaking treatment on cocksfoot seeds, wherein the concentration of the penicillin solution is 100-500 mg/L, and the treatment time is 6-24 hours. The germination rate of the cocksfoot seeds, subsequent growth property and the like are obviously enhanced as compared with the conventional clear water seed soaking, the germinative force of the cocksfoot seeds can reach 75-78%, and the germination rate can reach 78-83%; and the germinated cocksfoot seeds, which are subjected to seed soaking in the penicillin solution, have favorable growth property.
Description
The present patent application is application number 201210196504.6, the applying date on 06 14th, 2012, the dividing an application of denomination of invention " a kind of method that promotes that seed of cocksfoot germinates ".
Technical field
The present invention relates to a kind of method that improves percentage of seedgermination, particularly a kind of method that improves the seed of cocksfoot germination rate.
Background technology
Orchardgrass is vegetation well known in the art, is a kind of herbage raw material that is widely used in the livestock-raising, but it also has unique physiological feature; Orchardgrass (having another name called halymenia dentata, orchard grass, Dactylis glomerata L.) is perennial herb, dredges the clump type.The system of fibrous root is clouded in 10～30 centimetres the soil layer, and dark reaches more than 1 meter.Upright or the base portion knee song of stalk, high 70～120 centimetres (reaching more than 150 centimetres of cultivation).Leaf does not have hair slightly, and closure reaches more than the middle part usually, top tool ridge; Long 4～8 millimeters of the tip of a leaf, shape is torn on the top; Long 20～30 (45) centimetres of blade, wide 7～10 (12) millimeters.Panicle is carried out, long 5～20 (30) centimetres; The small ear poly combines in the top of branch, contains 2～5 flowers usually; The grain husk lanceolar, tip is point gradually, and long 4～5 (6.5) millimeters, tool 1～3 arteries and veins; First lemma and small ear are isometric, and the top tool is about 1 millimeter short awns.Caryopsis is long avette, yellowish-brown.
The under-supply situation of herbage grows in intensity at present.China's Developing of Animal Industry is very fast, and large-scale large-scale cultivation field is more and more, and intensive degree is also more and more higher, yet in raw material supply, supply does not reach the demand of animal husbandry development far away.Particularly on herbage produced, this breach was particularly huge.So how improving forage yield on the basis of existing cultivated area is exactly the major issue of needing solution at present badly.
Summary of the invention
The object of the present invention is to provide a kind of method that improves the seed of cocksfoot germination rate, adopt this method to handle seed of cocksfoot and can obtain higher germination vigor, germination rate and growth performance preferably.
The objective of the invention is to be achieved through the following technical solutions:
A kind of method that improves the seed of cocksfoot germination rate is characterized in that: it comprises adopts penicillin solution to the seed of cocksfoot processing of soaking seed, and the concentration of described penicillin solution is that 100mg/L～500mg/L, processing time are 6～24 hours.The inventor has creatively adopted penicillin solution to the seed of cocksfoot processing of soaking seed in long term production, the germination rate of discovery seed of cocksfoot, subsequent growth performance etc. are soaked seed than significantly improving with the clear water of routine, the germination vigor of its seed of cocksfoot can reach 75～78%, and germination rate can reach 78～83%; And it is good through the growth performance after the seed of cocksfoot germination of above-mentioned penicillin solution seed soaking.
Specifically, a kind of method that improves the seed of cocksfoot germination rate, carry out according to the following steps:
A. clean seed of cocksfoot: adopt machinery to clean also can adopt manually and clean, but artificial cleaning efficiency is low, time-consuming;
B. husky the Tibetan: seed is embedded in 1 ℃～4 ℃ the cold sand handle, the husky Tibetan time is 30 days;
C. seed soaking: adopt the processing of at room temperature soaking seed of the penicillin solution of 200mg/L, soak time is 18 hours;
D. alternating temperature is handled: placed room temperature following 5 hours with above-mentioned through the seed of cocksfoot after the seed soaking, and then be placed on 35 ℃ following 5 hours, 24 hours so repeatedly, during keep seed of cocksfoot moistening.In " the seed sprouting rules " of this area, the moistening definition of pair seed is arranged; Heating-up temperature is advisable with 35 ℃, and temperature is not crossed low not too high yet, otherwise does not reach the effect of heat treated or cause illeffects.
The present invention has following beneficial effect:
The penicillin of particular procedure concentration of the present invention soaks seed of cocksfoot, finds that its sprouting and growth are had facilitation.Adopt warm-cold seed treatment to accelerate the metabolic process of seed before sprouting, by the cold change of heat, promote kind of a skin fine fisssure, change its gas permeability, promote its suction, expansion, sprouting, its superiority is very outstanding; The inventive method is easy, simple to operate, can effectively improve the germination of this gramineous forage grass seed of similar orchardgrass with this method.
In addition, the inventive method is hidden effective cooperation that processing, specific seed soaking processing and specific alternating temperature are handled by sand, make the gained seed of cocksfoot that higher germination vigor, germination rate and growth performance preferably be arranged, the germination vigor of seed of cocksfoot can reach 85%, germination rate can reach 88%, has improved 15%～25% than common seed germinating method; The seed germination coefficient is up to 16.56; And at the back long 19.36cm of being of leaf that recorded plant in 20 days of emerging, the plant leaf area is 7.98cm
2Recorded the long 32.84cm of being of leaf of plant after emerging 40 days, the plant leaf area is 13.67cm
2The plant of more common germinating method has remarkable advantages aspect growth performance.Therefore adopt the present invention to promote the seed of cocksfoot germinating method, not only promoted the germination of seed of cocksfoot effectively, also improved the plant strain growth performance after seed of cocksfoot germinates simultaneously.
