| In order to improve the utilization of agricultural waste and reduce the environment pollution,This expriment took the cucumber species Jinlv No. 3 as material, and studied the effects of different ratios of thecow dung, peanut shell, peat, vermiculite and perlite on the growth and photosynthesis of cucumber seedlings. Theresults showed that the effect of different substrate ratios on the growth of cucumber was significant, the treatmentof C (peanut shell︰vermiculite︰Perlite=7︰3︰3, V︰V︰V) was the best after 40 days, the leaves of cucumberseedlings under C treatment were big, fleshy and dark green, and the plant height, stem diameter, aboveground andunderground fresh weight reached the maximum value, were 17.21 cm, 0.54 mm, 6.82 g and 2.26 g respectively,by 2.1 times, 1.5 times, 2.7 times and 1.1 times to control treatment respectively. The photosynthetic rate of Ctreatment was 13.95 μmol/(m2?s), which was slightly lower than that of A treatment, but no significant difference,and it was significantly higher than other treatments. Comprehensive each index, it was recommended that Ctreatment could be used in cucumber seedling by low cost and convenient source. |
