| Tripterygium wilfordii Hook. F is a new type of medicinal materials plant which has the very higheconomic value, because its demand rising, natural resources is reducing day by day, and develop artificialTripterygium wilfordii Hook. F planting has became a solution to solve exhaustion resource. So furtherunderstanding of its biological characteristics and ecological characteristics, refer to the other tree"fertilization and nutrition diagnosis research" method and the technical route, in view of its biologicalcharacteristics and ecological characteristics of its fertilization practice and nutrition diagnosis research isvery necessary. The Tripterygium wilfordii Hook. F annual seedlings as materials, Reach the influence ofthe Tripterygium wilfordii Hook. F salt stress and different fertilizer treatment on the active ingredients, themain results are as follows:⑴In the change of electrolyte permeability and malondialdehyde and the condition of salt stress,plant leaves electrolyte permeability are different degree of increased, in certain NaCl concentration range,the plant can reduce regulation through own salt stress on leaf of the cell damage, the plant can maintainthe stability and integrity of the cell, improve the salt stress adaptability to the environment of plants, thelimit for18mmol/LNaCl. Mda content of leaves in15days before the start of stress is increasing,15daysin reach maximum, and then began to decline, which ease in the limit of22.5mmol/L.⑵In proline content, in salt stress condition, in the period of seven processing in salt stress,20daysbefore of plant proline content of leaves in the relatively moderate growth,20days later began to rapidgrowth, and in the30days to peak, different NaCl concentration of salt stress under processing,45mmol/Lthe treatment effect is the most significant, and9mmol/L processing test the late with the increase of thecontent of proline played the inhibition.⑶In the enzyme activity, different NaCl concentration of processing tripterygium wilfordii blade SODactivity into different change trend, the treatment to27mmol/L in25days in the leaf blade handle SODactivity of the highest, and the ability to salt stress against the strongest. Along with the stress the extensionof time, the plant in the leaf blade is after rising to POD activity of the decline of the trend, tripterygiumwilfordii leaf in POD activity in22.5mmol/L treatment will reach the maximum under. Different NaClunder salt stress concentration of tripterygium wilfordii leaf in CAT activity mmol/L except for zero handlechange is more steady other seven processing are significantly more apparent fluctuations, including45mmol/L and27mmol/L of processing significantly higher than other CAT activity processing.⑷Different ratio fertilization for tripterygium wilfordii annual biomass and seedlings seedlings of highimpact on the potted tripterygium wilfordii annual seedlings use3414fertilization trial design, and theresults show that N, P, K three fertilizer fertilization for different ratio of tripterygium wilfordii biomassand seedling height has the influence of different level, the mathematical model we can calculate theoptimal scheme of the biggest growth for plant height35.10865cm, right now the most suitable N, P, K forthe amount of3.6g/basin respectively, and1.8g/basin,3.3g/basin. Begins in June to September theprocessing of the miao fresh weight increases rapidly, in addition to the11th processing (have seriousleaves phenomenon), and in July, the nutritional growth after started to diminish. The mathematical model we can calculate the optimum scheme of the biggest fresh weight of28.13598g, right now the mostsuitable for N, P, K for the amount of4.3g/basin respectively, and1.5g/basin,4.6g/basin.⑸Different ratio fertilization for tripterygium wilfordii annual seedlings physiological indexes effects,including activities of nitrate reductase, chlorophyll content, photosynthesis and plants medium armorelement content. After14to treatment5months of data processing, can draw N fertilizer for the usage ofthe annual tripterygium wilfordii seedling activities of nitrate reductase decisive role. The mathematicalmodel we can calculate the optimum scheme of the biggest activities of nitrate reductase for61.8u g g-1 h-1, right now the most suitable for N, P, K for the amount of4.1g/basin respectively, and1.9g/basin,3.6g/basin.⑹For different ratio fertilization, we can see,14processing content of chlorophyll in the main period inJune and July, and tripterygium wilfordii annual seedlings growth period of nutrition is consistent, of whichplants chlorophyll content is the highest annual10processing. The mathematical model we can calculatethe optimum scheme of the biggest chlorophyll content is4.1mg g-1 Fw, right now the most suitable forN, P, K for the amount of6.77g/basin respectively, and4.8g/basin,7.3g/basin.⑺For different fertilization for annual tripterygium wilfordii seedlings of the influence of photosynthesis,once upon a time in the data we can see that in July and August and September when the plant of the netphotosynthetic rate achieve maximum, among them with9and10processing the net photosynthetic rate isthe highest. The mathematical model we can calculate theoptimum scheme of the biggest netphotosynthetic rate of4.1mg g-1 Fw, right now the most suitable for N, P, K for the amount of6.4g/basin respectively, and3.1g/basin,3.2g/basin.⑻For meat content in plant medium armor, the mathematical model we can calculate the optimum schemeof the biggest net photosynthetic rate of4.1mg g-1 Fw, right now the most suitable for N, P, K for theamount of6.4g/basin respectively, and3.1g/basin,3.2g/basin. |
