Degradates On The Meadow And Improves And Resumes Studing In The West Of Jilin Province

Was unreasonable in view of the recent years aneurolepidium chinense lawn use, number of animals sustainable oversized, appeared the varying degree degeneration and the salination question. In order to improve the lawn plant survival requirement, to the degeneration, the salination lawn carried on a kind of grass, has herded, the different measure improvement experimental study. The result indicated that, after planted 4 pasturages to improve the soil nutrient condition, increased in the soil the nitrogen, the phosphorus and the potassium, the haughty Chinese alfalfa effect was best, the total nitrogen and the fast-acting nitrogen contentincreased 0.50% and 31.91mg/Kg separately, in the soil the entire phosphorus and the fast-acting phosphorus content increases 0.252% and 11.33mg/Kg separately, in the soil the fast-acting potassium content increases 24.37mg/Kg. The salt content and pH have the varying degree to reduce, is best is the alkali cogon grass, the salt content and pH drops 0.058 separately and 0.9, next for Hordeum brevisubulatum (Trin.) Link.cv.Junxu No.1, the salt content and pH drops 0.04 separately and 0.74. Compatible, combats drought, resists the cold, bears salt alkaloid, the output high, the quality is good. Three kind of improvements all improves sloppily the habitat, the increase soil fast-acting nutrient, the increase forage grass accounts for the proportion in the grass group. Applies fertilizer the improvement to cause the leguminosae and the compositae forage grass the proportion increases 39.9%-19.8% separately in the grass group compared to the control farm plot and 27.5%-34.4%, causes the gramineae forage grass proportion to reduce 21.3%-15.3%, may eat the forage grass output to increase 22.0%-57.8%. The railing seals nurtures causes the leguminosae and the compositae forage grass increases 26.7-13.4% separately and 4.7%-9.0%, may eat the forage grass output to increase 13.1%-78.0%. Shallowly plows under causes the leguminosae and the compositae forage grass proportion increases 27.3%-17.7% separately, 23.2%-36.3%, the gramineae forage grass proportion reduces 12.1%-10.1%, may eat the forage grass output to increase -28.5%-28.6%. From this obtains, applies fertilizer with the railing seals nurtures is the lawn improvement effective way. Through herds the intensity to the aneurolepidium chinense lawn vegetation and the domestic animal production influence research, herded the intensity varying degree to change the soil nutrient condition, three kinds herded the intensity land-flora plant community,the density, the degree of cover, the frequency, may eat the forage grass output highly not to have the obvious change, the group the difference are not remarkable (P > 0.05). Herds the intensity influence wether body weight. The wether date growth along with herds the intensity to reduce but increases, wether growth quantity take center group as best, center the component compared to the low group, the high group do not enhance 30.4%, 17.6%, the mean diurnal growth quantity group the difference is remarkable (P < 0.05); The forage grass dry matter archery target picks the food quantity influence wether growth quantity, but the date picks in the food quantity the thick protein to compare the influence which the dry matter confrontation wether grows to be more important. The lawn herds take the center herds the intensity (6/hm2) as best.
