| Sabina vulgaris and Herba Portulacae are two kinds of excellent plant resources with a variety of agricultural active ingredient. Therefore, they are widely used in scientific research and product development. However, they also produce a large number of plant residues, which results in a series of issues, such as wasting resources, polluting environment and increasing product cost. Therefore, they are composted by Research & Development Center of Biorathional Pesticide, Northwest A&F University. This dissertation focused particularly on study the growth and diseases of cucumber systematically with S. vulgaris compost,H. Portulacae compost and their compost tea. The main results are as follows:1. The Effect of the refuse compost of two pesticide plants, Sabina vulgaris Ant and Portulaca oleracea L, on population number of microbes, the growth and development, yield and quality of cucumber was studied by field trials in greenhouse. Results showed that use of the two compost both can improve soil microbial numbers in rhizospher, induce the growth and development, raise yield and quality of cucumber. Compared with the control, cucumber yield increased by 12.2% and 28.0%, respectively; soluble sugar and soluble proteins contents in cucumber increased by 16.62% and 4.04%, respectively, after use of the refuse compost of S. vulgaris Ant; and increased by 30.98% and 2.40%, respectively, after use of the refuse compost of P. oleracea L. The content of nitrate in fruits had no obvious change, but the content of Vc decreased.2. The inhibitory activity of the compost tea of Sabina vulgaris Ant and Portulaca oleracea L on Botrytis cinerea Pers, Psudoperonospora cubensi and Collectotrichum lagenarium was determined by methods of spore germination and potted plants, respectively. Results of the method of spore germination indicated that the compost tea of P. oleracea L had high inhibitory activity on spore germination of B. cinerea Pers and C. lagenariu, with the inhibitory rate of 78.69% and 60.28%, respectively, but low on that of P. cubensis. The inhibitory activity of the compost tea of S. vulgaris Ant on the three diseases was contrary to that of P. oleracea L and had high inhibitory activity on spore germination of P. cubensis with inhibitory rate of 59.75%. Results of the potted plants indicated that the control effect of two compost tea on the three diseases increased with increasing concentration. The two both showed highest inhibitory activity on B. cinerea Pers at the content of 100%, with the protective effect of 66.30% and 61.02%, and the therapeutic effect of 78.72% and 76.75%, respectively, followed by P. cubensis and C. lagenarium.3. The stress resistance of cucumber plants caused by S. vulgaris compost and H. Portulacae compost were tested. Results showed that the chlorophyll content both increased after application of two composts and decreased the content of MDA. Meanwhile, they can induced enhanced activity of SOD,POD and CAT. Therefore, it was concluded that the two composts both can enhanced the dresses-resistant of the cucumber plants.4. The effects of S. vulgaris compost and H. Portulacae compost on control of Meloidogyne incognita and their oocyst and hatch of individual eggs was tested in vitro and in vivo. Results (in vivo) showed that the S. vulgaris compost exhibited high inhibitory effect on hatch of oocyst, with inhibitory rate of 37.10% when that content of S. vulgaris compost was 60%. The S. vulgaris compost and H. Portulacae compost exhibited high inhibitory effect on the hatch of individual eggs, with inhibitory rate of 39.34%,46.72%and 37.70%, respectively, when 40% and 60% content of S. vulgaris compost and 40% of H. Portulacae compost. The potted trials results showed that the number of root- knot and the number of nematodes in soil and root were obviously lower than that of the control 30 d later, which decreased by 40.69%,39.39% and 45.46%, respectively, after using of S. vulgaris compost (40%) and decreased by 42.16%,27.38%and 35.29%, respectively, after using of H. Portulacae compost (40%).
