In addition, the research and development of existing plane monitor method and supporting technology get more and more, especially in recent years some desertificated area revegetations and plane monitor method utilize technology to promote at home and abroad to come, being exclusively used in caragana microphylla plane monitor method and Bush Cutter as have developed in the Inner Mongol.But these technology crops for rotation are low, not easily implement in southwestern Mountainous Area, promote difficulty large.Compared with prior art, the present invention adopts high-stubble rejuvenation technique, has both improved the biological yield of shrub, realizes again the mechanization of stump, has simple to operate, that cost is low advantage, has greater promotion potential and practical value in southwestern Mountainous Area.
Summary of the invention
The object of the invention is: provide a kind of shrub Sophora viciifolia high-order plane monitor method method, it can effectively raise economy and the ecological benefits of shrub Sophora viciifolia shrubbery, have simple to operate, that cost is low advantage, after Sophora viciifolia stump, resume speed is very fast, and stump harvesting is than being easier to.
The present invention is achieved in that the high-order plane monitor method method of shrub Sophora viciifolia, and Sophora viciifolia more than 1 age is carried out stump at non-acoustic detection, and crops for rotation height is apart from ground 45-55cm, and the annual stump of Sophora viciifolia once, promotes crops for rotation 1-2cm next time.
Stump generally should carry out Sophora viciifolia poor growth or plateau at the beginning of the winter, and in the middle of 1 year, Sophora viciifolia general early April starts to branch out, 5, bloom June, July, young fruit was formed, and August, seed started maturation, 9 to October self-sow, the middle and later periods in November binds, and this is relevant to local temperature and rainfall.
Different stump cycle, stump period and stubble height have a certain impact to growing of Sophora viciifolia, and therefore, research stump cycle, stump period and stubble height aborning tool have very important significance.Inventor is to the investigation of Dushan County, Guizhou Province county in the Sophora viciifolia stump of sowing in 2010, and investigation result is as shown in table 1-3:
(1) the stump cycle is on the impact of shrubbery growth recovery
, Cong Mengzhi number, every batch clump biomass and New shoot growth amount high to the 2 years clumps of raw Sophora viciifolia shrubbery after 2012-2013 stump are investigated, through the recovery of 1 Growing season after stump, the proterties such as Cong Gao, Cong Mengzhi number, every batch of clump biomass and New shoot growth amount all there occurs change.Compared with non-stump, stump number of times 4 times, 2 times and 1 clump is high has recovered 40.66%, 66.91% and 71.89% respectively successively, Cong Mengzhi number returns to 4.8 times, 3.6 times and 1.9 times of non-stump Cong Meng branch number respectively, clump biomass reaches 1.29 times, 1.68 times and 1.25 times of non-stump respectively, and New shoot growth amount is respectively 1.9 times, 4.9 times and 3.2 times of non-stump.Visible, after stump, 1 year resume speed is very fast, and now due to leading thread recovery extent < 2cm, stump harvesting is than being easier to.
(2) Various Seasonal stump is on the impact of shrubbery growth recovery
Show the result that the Sophora viciifolia germination rate of spring, summer, autumn, the four seasons in winter stump is observed, the stump germination rate of Various Seasonal has certain otherness, safer with stump in winter, and the lethality after stump is lower.Further from the shrubbery age, along with the increase in shrubbery age, the lethality after stump is reduction trend, and wherein the stump mortality difference level in each season of 2,3 years is little.To 1 year raw shrubbery, each season all there are the phenomena of mortality in various degree in Sophora viciifolia stump; 1 year raw Sophora viciifolia shrubbery spring and autumn stump there will be Serious Mortality phenomenon, 2 years raw Sophora viciifolia shrubberies spring stump there are the phenomena of mortality, but lethality is lower, and this is with spring drought and easily drain relevant.Therefore, the Sophora viciifolia shrubbery within life in 1 year does not advocate stump.
(3) different stubble height is on the impact of shrubbery growth recovery
To stubble height be 5,10,20,30,50, the Sophora viciifolia of 70cm is when annual clump is high, descendant number, sprout tillers branch length and growing way situation are investigated, to determine that the stubble height be suitable for is instructed stump operation.Growth selection uniform 2 years raw Sophora viciifolia shrubberies, carry out test observation and compared with (CK) before stump, stump stubble height is 5,10,20,30,50,70cm time, the average clump of Sophora viciifolia shrubbery is high then reaches 62.21%, 60.5%, 68.29%, 65.94%, 71.97%, 79.26% before stump respectively; Sophora viciifolia is best when stump stubble height is 50cm, and Cong Mengzhi number, New shoot growth amount reach 400.17% and 250.45% before stump respectively; Secondly be toothing 70cm.Therefore, the suitable height of stump is 50cm, the operation of portable brush saw stump operation.
(4) shrubbery is suitable for the determination of stump phase
shrubbery non-acoustic detection joint stumpshrubbery non-acoustic detection joint stump--resting stage stump.Sophora viciifolia shrubbery saves (December first arrival February next year) stump at whole non-acoustic detection, and the plant lethality caused is very low.1. branch crude protein content is more stable; 2. now branch is more crisp, and artificial felling work efficiency is than high at Growing season, and be again farm slack season, labour is sufficient, stump advantage of lower cost simultaneously; 3. spring can germination and growth as early as possible, and vegetative period good for the year of issue only is long, and biomass is large, next year just can be solid on a small quantity, then just can be normally solid.
the shrubbery nutrition stump phaseshrubbery nutrition stump phase--the best nutritional stump phase.The measurement result of Various Seasonal Sophora viciifolia shrubbery branch nutrient composition content shows, be worth best at summer nutritional, now carrying out stump has following advantage: one is the recovery that stump can not affect Sophora viciifolia shrubbery, and after stump, plant lethality is also low; Two is summers is shrubbery vigorous growth peak periods, and now the florescence is shortly past entering pod bearing period, and greatly, the feeding quality of processing is better, and gross protein value is higher than non-raw season, and crude fiber content is low, and in raw fiber, content of lignin is low for spray amount and leaf amount.
the shrubbery maximum biomass stump phasesophora viciifolia shrubbery is after the best nutritional phase in summer, and the crude protein content of branch is on a declining curve, minimum to autumn.Summer, stump had certain phenomena of mortality; Autumn is then that dry accumulates maximum months then, in the period that branches and leaves amount is many, also has certain phenomena of mortality after stump; Season at the beginning of winter, stump was that shoot germinated plantlet Seedling height is about to the transition period of stopping then, and clump strain amount of growth has been tending towards slow, and germination and growth is fast, and riotous growth biomass of turning green the 2nd year spring is large.
shrubbery is suitable for the determination in stump cyclesophora viciifolia shrubbery is suitable for the determination in stump cycle, and because of the difference of Land use systems and object, specific requirement is also different.Low as feed request degree of lignification, branch is fresh and tender, and in crude fibre, raw fiber, content of lignin is low, is conducive to processing and improves utilization ratio and feeding quality etc., needs suitably to shorten the cutting utilization cycle.Think according to test observation result, a large amount of High quality processing raw material be obtained, significantly improve stump, processing effect and shrubbery quality of the fodder, the renewal of the plane monitor method of Sophora viciifolia shrubbery should be utilized the cycle foreshortened to by 1 year and be advisable the 6-10 month.
shrubbery is suitable for the determination of stump modethe protection of ecology and resource must be taken into account to the cutting utilization of Sophora viciifolia shrubbery feed.With interlacing by stages, stump is for major way year by year, and namely plane monitor method upgrades and utilizes the cycle to be 1 year, with every 1 row or 2-3 capable stump 1 row, effectively can reduce rock land table water erosion harm, improve shrubland water retention capacity.For obtaining more shrubbery feed manufacturing raw material, also can take every 1-3 capable stump 1 row.During stump, stubble height answers >30cm, can strengthen rudiment occurrence rate after stump like this, be beneficial to next cutting utilization.No matter when stump, all must not injure plant tillering point.The shrubbery age is less, and the shrubbery particularly below 1 age is unsuitable stump in Growing season.
Owing to have employed technique scheme, compared with prior art, the present invention solves the increase at Sophora viciifolia shrubbery age, easily occurs the problem growing decline; The research and development of existing plane monitor method and supporting technology get more and more, and some desertificated area revegetations and plane monitor method utilize technology to promote at home and abroad to come, being exclusively used in caragana microphylla plane monitor method and Bush Cutter as have developed in the Inner Mongol especially in recent years.But these technology crops for rotation are low, not easily implement in Southwest Mountainous Areas, promote difficulty large.Compared with prior art, the present invention adopts high-stubble rejuvenation technique, has both improved the biological yield of shrub, realizes again the mechanization of stump, has simple to operate, that cost is low advantage, has greater promotion potential and practical value in Southwest Mountainous Areas.The inventive method operating procedure is simple, is easy to promote, and effectively can reduce rock land table water erosion harm, improve shrubbery forage yield, and rudiment occurrence rate after enhancing stump, destroys plant diseases and insect pests, produce larger economic benefit and ecological benefits.
