【摘要】：本試驗(yàn)采用隨機(jī)區(qū)組設(shè)計(jì),研究噴施寶對(duì)圓齒野鴉椿兩年生苗生長及生理特性的影響,以篩選出促進(jìn)圓齒野鴉椿苗木生長、提高苗木抗逆性的噴施寶最佳使用濃度,為圓齒野鴉椿苗木生產(chǎn)提供參考。試驗(yàn)結(jié)果表明:(1)噴施寶具有促進(jìn)圓齒野鴉椿苗木生長的作用。當(dāng)噴施寶濃度為0.50 m L·L~(-1)時(shí),苗高增長量最大,與對(duì)照相比差異達(dá)極顯著水平;噴施寶濃度從0.33 m L·L~(-1)~2.0m L·L~(-1)之間差異均不顯著。當(dāng)噴施寶濃度為2.0 m L·L~(-1)時(shí),地徑增長量最大,與對(duì)照相比差異達(dá)顯著水平;噴施寶濃度從0.25 m L·L~(-1)~2.0 m L·L~(-1)之間差異不顯著。噴施寶濃度為1.0 m L·L~(-1)時(shí),苗木生物量和根冠比最大,但各處理之間差異不顯著。故從保護(hù)生態(tài)和降低成本的角度考慮,促進(jìn)圓齒野鴉椿苗木生長的噴施寶最佳使用濃度為0.33 m L·L~(-1)~0.50 m L·L~(-1)。(2)噴施寶具有提高圓齒野鴉椿苗木葉片中的可溶性糖、可溶性蛋白質(zhì)的含量,以及超氧化物歧化酶(SOD)、過氧化物酶(POD)、過氧化氫酶(CAT)的活性,從而可以提高苗木的抗逆性。利用隸屬函數(shù)法對(duì)苗木的抗逆性進(jìn)行綜合評(píng)價(jià),結(jié)果表明,各處理苗木的抗逆性由強(qiáng)到弱排序依次為:處理3(0.50 m L·L~(-1))處理2(0.33 m L·L~(-1))處理1(0.25 m L·L~(-1))處理4(1.00 m L·L~(-1))處理5(2.00 m L·L~(-1))CK(噴清水),即處理3:噴施寶濃度為0.50 m L·L~(-1)時(shí)苗木的抗性最強(qiáng)。(3)噴施寶可顯著提高圓齒野鴉椿苗木葉片中葉綠素及氮素養(yǎng)分的含量,從而促進(jìn)苗木生長。噴施寶濃度為1.0 m L·L~(-1)~2.0 m L·L~(-1)時(shí),苗木葉片中的葉綠素及氮元素含量最高。并且葉綠素及氮元素含量均與苗高增量呈顯著正相關(guān),與地徑增量呈極顯著正相關(guān)。(4)噴施寶還可顯著提高土壤中的氮含量,噴施寶濃度為1.0 m L·L~(-1)~2.0 m L·L~(-1)時(shí),土壤氮含量最高。噴施寶對(duì)土壤中磷含量無顯著影響,但施用噴施寶后土壤含磷量均較噴施前土壤含磷量低;此外,噴施寶會(huì)顯著降低土壤鉀含量,可見,噴施寶可促進(jìn)苗木對(duì)土壤磷、鉀的吸收;因此,生產(chǎn)上在施用噴施寶葉面肥的同時(shí),應(yīng)增加磷、鉀肥的施用量。
[Abstract]:In this study, a randomized block design was used to study the effects of spraying Bao on the growth and physiological characteristics of two year old seedlings of Toona sinensis, in order to screen out the best concentration of spraying Bao to promote the growth and improve the resistance of the seedlings. It provides a reference for the seedling production of Toona davidifolia. The results showed that the effect of spraying treasure on the seedling growth of Toona sinensis was improved. When the concentration of spraying treasure was 0.50 mL / L, the seedling height increased the most, and the difference was very significant compared with the control, but there was no significant difference between spraying concentration from 0.33 mL / L ~ (-1) ~ (-1) to 2.0 mL / L ~ (-1). When the concentration of spraying treasure was 2.0 mL / L ~ (-1), the increase of ground diameter was the largest, and the difference was significant compared with the control, but there was no significant difference between the concentration of spraying treasure from 0.25 mL / L ~ (-1) ~ (2. 0 mL / L ~ (-1) ~ (-1). The biomass and root-shoot ratio of seedlings were the largest when the concentration of spraying treasure was 1.0 mL / L ~ (-1), but there was no significant difference among the treatments. Therefore, from the point of view of protecting ecology and reducing the cost, the optimum application concentration of spraying treasure to promote the growth of Toona sinensis seedlings is 0.33 mL / L Lnelmina (0.50 mL / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L / L ~ (-1) / L ~ (-1) ~ (-1). The activities of superoxide dismutase (SOD), peroxidase (POD) and catalase (catalase) can improve the stress resistance of seedlings. The method of membership function was used to evaluate the stress resistance of seedlings. The order of the stress resistance of each treatment was: treatment 30.50ml / L / L ~ (1 / L) treatment 2n / 0.33m / L / L / L / L / L ~ (1 / 1) treatment _ (1n ~ (0.25) m / L / L / L ~ (1 /) treatment (41.00 m / L / L / L / L / L ~ (1) treatment (52.00m / L / L / L / L / L ~ (1) CK (treatment 3: spraying concentration = 0.50 mL / L / L / L ~ (-1) the resistance of the seedlings was the strongest. (~ (3) ~ (3) ~ (1) = 0.50 mL / L / L / L / L ~ (+) ~ (-1) Spraying with Bao could significantly increase the content of chlorophyll and nitrogen in the leaves of Toona sinensis seedlings. So as to promote the growth of seedlings. The content of chlorophyll and nitrogen in seedling leaves was the highest when the concentration of spraying treasure was 1.0 mL / L ~ (-1) and 2.0 mL / L ~ (-1) / L ~ (-1). There was a significant positive correlation between chlorophyll and nitrogen content and seedling height increment, and a very significant positive correlation between chlorophyll content and basal diameter increment. (4) spraying Bao also significantly increased the nitrogen content in soil. The soil nitrogen content was the highest when the spraying concentration was 1.0 mL / L ~ (-1) and 2.0 mL / L 路L ~ (-1). Spraying treasure had no significant effect on phosphorus content in soil, but the phosphorus content of soil after spraying treasure was lower than that before spraying, in addition, spraying treasure could significantly reduce the content of potassium in soil. Therefore, the amount of phosphorus and potassium fertilizer should be increased when applying leaf fertilizer in production.
