Abstract
The invention discloses a seed treatment agent suitable for flooding resistance of hemarthria and application. The seed treatment agent is prepared from the following components: 150-180 mg/L calcium chloride, 100-150 mg/L boric acid, 10-30 mg/L silica gel, 20-30 mg/L polyvinyl alcohol and 1-5 mg/L naphthylacetic acid. The seed treatment agent disclosed by the invention can be used for effectively improving the flooding resistance of hemarthria seeds, can be used for improving the germination rate of the seeds and promoting elongation of roots if being used, and has relatively huge promotional value.
Description
Technical field
The invention belongs to plant seed process field, be specifically related to a kind of seed treatment and the application that are suitable for the resistance to water logging of Hemarthria compressa.
Background technology
Hemarthria compressa, Hemarthria (
hemarthria), perennial gramineous plants, kind is many, main by rhizome radiation breeding; Under different niches, plant type difference is obvious; Open habitat species, be born in more river bank moisteningly, marshland, ephemeral stream spread unchecked meadow, rice field or the moistening moistening place such as the ridge, farmland, ditch, river shoal; Often can not form sociales, mostly for association or scattered kind, in Upper-middle Reaches of Yangtze River wild Hemarthria compressa normal with Bermuda grass, vacation thrifty (
eremochloaop hiuroides), ditch millet (
p. distichum) etc. warm season grass seeds be accompanied; Distributed more widely, all have distribution from height above sea level 39 m to 2215 m, all there is existence (Yang Chunhua etc., 2004) northeast, North China, Central China, south China, southwestern various places.
Current Hemarthria compressa is widely used in the plantation of falling zone regional plant, and by man's activity, reservoir level cyclic fluctuation, falling zone plant is also corresponding stands periodic water logging and arid.Under complete water logging condition, plant oxygen supply reduces, and anaerobic respiration aggravates, the utilization ratio of carbohydrate significantly reduces, in aggravation body, the consumption (Gibbs & Greenway, 2003) of carbohydrate, is unfavorable for plant strain growth, survival.Especially also do not have enough time to germinate at the Hemarthria compressa seed of plantation and just meet with the situation that heavy rain rises, Hemarthria compressa seed is when complete water logging, germination rate and rooting rate all can be restricted, and therefore, invent a kind of resistance to water logging tool improving Hemarthria compressa seed and are of great significance.
Summary of the invention
An object of the present invention is to provide a kind of seed treatment being suitable for the resistance to water logging of Hemarthria compressa, can improve the resistance to water logging of Hemarthria compressa seed, when water logging, does not affect its germination rate.Two of object is to provide a kind of seed treatment being suitable for the resistance to water logging of Hemarthria compressa and is improving the application in the resistance to water logging of Hemarthria compressa seed.Three of object is to provide a kind of application of seed treatment at raising Hemarthria compressa percentage of seedgermination being suitable for the resistance to water logging of Hemarthria compressa.Four of object is to provide a kind of seed treatment being suitable for the resistance to water logging of Hemarthria compressa and is promoting the application in Hemarthria compressa root growth.
For achieving the above object, the invention provides following technical scheme:
1, be suitable for the seed treatment of the resistance to water logging of Hemarthria compressa, its proportioning is as follows: calcium chloride 150 ~ 180mg/L, boric acid 100 ~ 150mg/L, silica gel 10 ~ 30mg/L, polyvinyl alcohol 20 ~ 30 mg/L, methyl α-naphthyl acetate 1 ~ 5mg/L.
Preferably, the above-mentioned proportioning being suitable for the seed treatment of the resistance to water logging of Hemarthria compressa is as follows: calcium chloride 160mg/L, boric acid 120mg/L, silica gel 20mg/L, polyvinyl alcohol 25 mg/L, methyl α-naphthyl acetate 3mg/L.
Seed is soaked 12 ~ 24h in above-mentioned solution, cleans with clear water after taking out seed, sow immediately after drying.
2, the seed treatment being suitable for the resistance to water logging of Hemarthria compressa described in is improving the application in the resistance to water logging of Hemarthria compressa seed.
3, the seed treatment of the resistance to water logging of Hemarthria compressa is suitable for described in the application improving Hemarthria compressa percentage of seedgermination.
4, the seed treatment being suitable for the resistance to water logging of Hemarthria compressa described in is promoting the application in Hemarthria compressa root growth.
The invention has the beneficial effects as follows:
The present invention has input low, high efficiency, feature simple to operate, the calcium chloride adopted, boric acid effectively can provide the nutriment required for seed germination, silica gel has the characteristic absorbing moisture, effectively can lock water, and polyvinyl alcohol can wrap up thin film around seed, reduce the immersion of moisture.
Seed soaks after 12 ~ 24 hours, and portion of water immerses seed, and silica gel pins portion of water, and after seed is by water logging, polyvinyl alcohol can have the quick infiltration slowing down moisture, and minimizing seed soaks for a long time and rots in water.Methyl α-naphthyl acetate effectively can promote that Hemarthria compressa germinates and take root.
The germination rate of seed can be improved after using, promote the elongation of root have larger promotional value.
Embodiment
The experimental technique used in following embodiment if no special instructions, is conventional method.
Material used in following embodiment, reagent etc., if no special instructions, all can obtain from commercial channels.
Embodiment
Process 1:
By calcium chloride 150mg, boric acid 100mg, silica gel 10mg, polyvinyl alcohol 20mg, methyl α-naphthyl acetate 1mg, add the aqueous solution, be uniformly mixed, constant volume is 1L.
Seed is soaked 24 hours in above-mentioned solution, cleans with clear water after taking out seed, sow immediately after drying.
Process 2:
By calcium chloride 160mg, boric acid 120mg, silica gel 20mg, polyvinyl alcohol 25 mg, methyl α-naphthyl acetate 3mg, add the aqueous solution, be uniformly mixed, constant volume is 1L.
Seed is soaked 18h in above-mentioned solution, cleans with clear water after taking out seed, sow immediately after drying.
Process 3:
By calcium chloride 180mg, boric acid 150mg, silica gel 30mg, polyvinyl alcohol 30mg, methyl α-naphthyl acetate 5mg, add the aqueous solution, be uniformly mixed, constant volume is 1L.
Seed is soaked 12h in above-mentioned solution, cleans with clear water after taking out seed, sow immediately after drying.
Process 4:
Seed is soaked 0h, 12h, 18h, 24h(control group respectively in clear water), clean with clear water after taking out seed, sow immediately after drying.
Planted respectively in seedling-cultivating tray by Hemarthria compressa seed through above-mentioned process, often kind of process is divided into 5 parts, after seedling-cultivating tray is immersed in the water 1,2,3,4,5 day completely, seedling-cultivating tray is taken out from water, places and observe under normal operation, record, its germination rate is added up, the results are shown in Table 1.As can be seen from the comparison result, method of the present invention is utilized to process seed, along with the lengthening of water logging time, percentage of seedgermination through process of the present invention and contrast groups all reduces, and visible Hemarthria compressa does not have patience to water logging, as can be seen from the contrast of the present invention and contrast groups, the present invention effectively can improve the resistance to water logging of Hemarthria compressa seed, and when water logging, the germination rate of Hemarthria compressa seed is obviously than untreated height, and the growing state of root is apparently higher than contrast groups.
The germination rate of table 1 different disposal Hemarthria compressa compares
Normal management is continued for the Hemarthria compressa germinateed, after 30 days, add up its root length, fibrous root number, the present invention contrasted control group, its root is long than contrast group leader 20 ~ 30%, fibrous root number more than control group 25 ~ 35%, visible the present invention can promote the growth of pizzle grass roots.
