【摘要】：千屈菜(Lythrum salicariaLinn.)是一類良好的草花,它的植叢規(guī)整俊秀、素雅,景觀里可以池塘里作為花境。千屈菜的生命力非常強,耐寒、耐貧瘠,有著很好的推廣運用遠景,苗木需求量不斷增加。為加速培養(yǎng),配合景觀改造配置的要求,展開各式各樣形式千屈菜培養(yǎng)實驗,以最高的效率供給大批需求。采取迥異的種植方式將嫩枝扦插成團的千屈菜開展栽培實驗,尋求最好的種植渠道,探尋效率佳、景觀效果好、經(jīng)濟效益顯著的繁育方法。本試驗為不同部位的千屈菜根據(jù)試驗設(shè)計在不同灌水周期、不同的生長條件和不同的施肥條件下觀測千屈菜的生長狀態(tài)。采取觀測千屈菜生長的生物量指標的方式,通過正交試驗得出適宜千屈菜生長為最佳景觀效果的最優(yōu)栽培前提,為千屈菜在內(nèi)蒙區(qū)域的景觀效益種植推廣供給。這次試驗的的研究方法設(shè)計為9個區(qū)域開展,并且重復(fù)一次,具體安排的因素分別為:植株部位為全株、半株、留兩葉,灌水周期的三個水平為3天、7天、14天,種植條件為覆膜、搭弓棚、裸地,追肥種類為不追肥、尿素、復(fù)合肥。重點研究在不同栽培條件中千屈菜的成活率以及植株苗高增量、分枝數(shù)增量、葉片數(shù)增量等,以此選出適宜及不適宜其生長的環(huán)境條件和景觀效益最優(yōu)組合。定期觀測千屈菜的生長指標,如成活率、苗高、分枝數(shù)、葉片數(shù)、葉面積、開花數(shù)量、開花高度、地上部分和地下部分的重量。試驗得出如下結(jié)論:(1)在覆膜情況下,以3天為灌水周期,追復(fù)合肥的留兩葉千屈菜苗高長勢最好;在弓棚情況下,以3天為灌水周期,追尿素的半株千屈菜苗高長勢最好;在裸地上,以14天為灌輸周期,追尿素的留兩葉千屈菜苗高長勢最好。綜合分析,在覆膜情況下,以3天為灌水周期,追復(fù)合肥的留兩葉千屈菜為全部千屈菜植株中苗高長勢最好的。(2)全株千屈菜在以14天為灌水周期,地面搭弓棚,追復(fù)合肥的情況下,開花高度增量最高;半株千屈菜在以3天為灌水周期,地面覆膜,追復(fù)合肥的情況下,開花高度增量最高;留兩葉千屈菜在以7天為灌水周期,地面不處理,追復(fù)合肥的情況下,開花高度增量最高。(3)本次正交實驗的最佳組合是A1B1C3D3也就是在千屈菜是全株,灌水周期為3天,種植條件為塑膜覆膜時,追復(fù)合肥時,千屈菜存活率、苗高、生長情況、開花效果等達到最優(yōu)。
[Abstract]:Lythrum salicaria Linn.) Is a good kind of grass flowers, its plantations are beautiful, elegant, the landscape can be used as a flower pond. The vitality of Qianqu is very strong, cold-resistant, barren, has a good prospect of promotion and application, seedling demand continues to increase. In order to speed up cultivation and meet the requirements of landscape transformation and configuration, various cultivation experiments were carried out in order to supply large quantities of demand with the highest efficiency. In order to find the best planting channel, the cultivation experiment was carried out by using different planting methods. The breeding methods with good efficiency, good landscape effect and remarkable economic benefit were explored. According to the experimental design, the growth state of Dioscorea chinensis was observed under different irrigation periods, different growth conditions and different fertilization conditions. By using the method of observing the biomass index of the growth of Dioscorea davidii, the optimum cultivation premise of the optimum landscape effect was obtained by orthogonal experiment, which was the supply of landscape benefit planting in Inner Mongolia. The research method of this experiment was designed for 9 regions and repeated once. The specific factors were as follows: whole plant, half plant, two leaves, three levels of irrigation cycle were 3 days, 7 days and 14 days, respectively. The conditions of planting were film mulching, bow shed, bare land, non-topdressing, urea and compound fertilizer. The survival rate, seedling height increment, branch number increment, leaf number increment and so on were studied in different cultivation conditions, so as to select the best combination of environmental conditions and landscape benefit that were suitable and unsuitable for their growth. The growth indexes such as survival rate, seedling height, branch number, leaf number, leaf area, number of flowers, flowering height, weight of aboveground and underground parts were observed regularly. The results showed as follows: under the condition of film mulching, under the condition of film mulching, the period of irrigation was 3 days, the height of seedlings with two leaves of compound fertilizer was the best, and in the case of bow shed, the seedling height of half a plant of Urea was the best when the period of irrigation was 3 days. On bare ground, 14 days inculcating cycle, the highest seedling height of Urea was the best. Comprehensive analysis showed that under the condition of film mulching, under the condition of 3 days as the irrigation cycle, the best seedling height of the whole plant was the leaves of two leaves of the compound fertilizer, and the highest seedling height. (2) the whole plant was irrigated with 14 days as the irrigation cycle, and the ground bow shed was set up. In the case of compound fertilizer topdressing, the flowering height increment was the highest; the flowering height increment was the highest in the case of three days of irrigation, the highest increase of flowering height in the case of surface mulching and compound fertilizer, and the highest increase of flowering height in 7 days. The best combination of this orthogonal experiment is that A1B1C3D3 is the whole plant, the irrigation period is 3 days, and the planting condition is plastic film mulching, when the compound fertilizer is applied, the best combination of this orthogonal experiment is when the plant is the whole plant, the irrigation period is 3 days, and the planting condition is plastic film mulching. The survival rate, seedling height, growth condition and flowering effect were optimal.
