Description
Technical field:
The utility model relates to a kind of measurer, specifically refers to a kind of alfalfa Cutting Height positioning rule.
background technology:
Alfalfa is herbaceos perennial, and like clover, drought-resistant, cold-hot, output is high and of fine quality, can improve soil again, thus known.Extensive cultivation, mainly with haying, silage fodder or be used as herbage.Alfalfa is famous with " King of Pasture ", and not only output is high, and herbaceous stem is excellent, the equal eating of various livestock and poultry.Cultivated area about 1,330,000 hm^2 of China clover.Along with the development of commodity economy, Alfalfa industrialization scale development is very fast, and the cultivated area of clover expands.Alfalfa is the perennial grass of high yield, has good reviviscence, within 1 year, can cradle 3 ~ 8 times.Utilize farmland planting can obtain higher Herbage harvest and protein output, in Production of Large Fields, due to the difference of clover Clipping dates, its output, water content, protein content and crude fiber content have larger difference.
At present, China clover mainly with clover initial bloom stage for standard cradles, but during large area operation, Chang Yin cradles the impact of the factors such as speed, weather condition, soil condition, not only can not complete within a breeding time and cradle, even can be extended to next breeding time.The simultaneously determination of breeding time does not have absolute standard yet, therefore, is that clover cradles standard and can not instruct actual production accurately with breeding time.
For the correlation of the alfalfa height nutriment corresponding with it, related researcher tests, demonstrate between the growing height of alfalfa and its nutriment contained and there is corresponding relation, thus can to break with clover breeding time be that the tradition cradling standard cradles method, change into alfalfa growing height for standard, for the utility model provides a kind of alfalfa Cutting Height positioning rule to provide the foundation.
Principle and the process of relevant pale reddish brown alfalfa Cutting Height test are as follows:
Just regeneration period is entered through of short duration dormancy after pale reddish brown alfalfa cradles, the speed of pale reddish brown alfalfa regeneration presents the trend of " slow-fast-slow ", this test starts when reaching 20cm with pale reddish brown Growth of Alfalfa height to measure, namely when Medicago sativa height reaches 20cm, every 3d it measured and sample, when Growth of Alfalfa height reaches 60cm, sampling interval becomes greatly every 10d, until Growth of Alfalfa speed stops.
Correlation analysis is carried out to nutriment that differing heights samples, to determine that the best cradles standard.
1, by the best cut issue test of height gauge determination alfalfa
(1) experimental field in choose several communities, each plot area is 9m
2, start when this test reaches 20cm with Growth of Alfalfa height to measure, when namely Medicago sativa height reaches 20cm, every 3d, it measured, record, sample.
(2) breeding time that different districts is corresponding different respectively, each stubble all cradles at this cut issue, takes manually to cradle, and stubble height is 5 ~ 6cm.When cradling record cradle kind, time, place, weather conditions, temperature, surface temperature, air humidity, whether irrigate, fertilising etc.
(3) each community, each batch of alfalfa all need sampling about 500 grams after cradling, and are wrapped in newspaper, carry out mark, to carry out nutrient component determining in the future after oven dry.
(4), after nutrition measuration, complete that nutritive index is corresponding with different growing height to be shown.
The output of different growing height alfalfa and nutrient component (%DM)
The domestic research for the Growth of Alfalfa height corresponding to the suitableeest cut issue is less at present, does not correspondingly almost have the research of the special height gauge of location alfalfa cutting-height.
