Abstract:

Organic substrate planting board cultivation is suitable for automated organic fertilizer application in solar greenhouse. In order to investigate the effects of organic substrate planting board cultivation on the decomposition characteristics and nutrient releasing patterns of organic materials,and nutrient absorption and growth of crop,‘Zhongnong 46’cucumber(Cucumis sativus L.)was used as the experimental material,and conducted field experiment with organic substrate planting board cultivation and conventional soil cultivation.The results showed that the decomposition rate of organic materials was faster in the first 30 days under organic substrate planting board cultivation and in the first 60 days under conventional soil cultivation,then slowed down until the end of the experiment under both treatments in autumn-winter season in 2021. The decomposition rate of organic substrate planting board cultivation was 3.7 percentage points higher than that of conventional soil cultivation at 30th day,however,7.8 percentage points lower at 120th day. The total N content of organic materials declined rapidly, while total P and K varied little during the experiment. The contents of alkaline N at 0-5 cm layers and the contents of available P and K at 0-5 and 5-15 cm layer under organic substrate planting board cultivation treatment were higher than that of conventional soil cultivation in autumn-winter season in 2021. Besides, the coefficients of variation of nutrients in the root zone of organic substrate planting board cultivation were greater than that of conventional soil cultivation in 2021. In 2023,the variation tendencies of alkaline N contents in the root zone were same as that in 2021,while there was no difference between two treatments in the contents and coefficients of variation of available P. The contents of N,P and K in cucumber leaves of organic substrate planting board cultivation treatment were equal to or greater than that of conventional soil cultivation in 2021,however,K content was 9.6% lower at 120th day in 2023. Meanwhile,the net photosynthetic rate(Pn),dry weights of above ground of organic substrate planting board cultivation treatment were significantly higher than that of conventional soil cultivation in 2021 and 2023. The yields of organic substrate planting board cultivation treatment did not differ from that of conventional soil cultivation in 2021,and was 10.9% higher in 2023. It is concluded that,the organic substrate planting board cultivation can retard the decomposition of organic material,however cucumber absorbed more nutrients due to the superiority of concentrated distribution in the root zone.
