Effect Of Substances On Eco-Organic Type Soilless Culture In Several Vegetable Plants

Aiming at the shortcomings of the soilless culture still exist and the current situation of the development of vegetable industry in Yanji. The experiment discussed the effect of different substrates for eco-organic type soilless culture of lettuce, cucumbers, peppers, tomato, strawberry growth. Investigate the weight and quality of the fruit from growth go postharvest, and select the best substrate formula to further solve these problems. For the future development in yanji organic ecotype soilless cultivation of vegetables industry foundation. The results indicated that:1. The growth characters of lettuce of substrate formulas T1 (peatmoss:perlite = 3:1) was the best. At this time, the number of the lettuce leaf is 43.4, the largest leaf length is 31.3 cm, the largest leaf width is 15.4 cm, and the highest production is 1105.3 g. The content of soluble sugar is 46.7 mg · g-1, the content of vitamin C is 5.01 mg · 100g-1.2. The growth characters of cucumbers of substrate formulas T1 (peatmoss: perlite= 3:1) was the best. At this time, the plant height is 135.3 cm, the stem diameter is 8.67 mm, the internodes lengths is 14.5 cm, the leaves of the plant is 12.4, and the petiole is 19.4 cm. The highest production is 857.3 g. The content of total sugar is 1.78%, the soluble solids is 3.8%, the organic acid is 0.132%, the vitamin C is 10.32mg·100g-1.3. The growth characters of peppers of substrate formulas T2 (peatmoss:perlite = 2:1) was the best. At this time, the plant height is 54.2 cm, the stem diameter is 8.76 mm, the leaves of the plant are 18.1, and the petiole is 3.4 cm. The highest production is 511.2 g. The content of soluble solids is 7.5%, the vitamin C is at 51.68 mg · 100g-1.4. The growth characters of tomato of substrate formulas T1 (peatmoss:perlite = 3:1) was the best. At this time, the plant height is 101.5 cm, the stem diameter is 5.87 mm, the internodes lengths is 2.8 cm, the leaves of the plant is 5.6, the area of leaf is 35.4 cm2. The highest production is 1106.0 g. The content of organic acid is 3.7%, soluble solids is 4.54%, the reducing sugar is 23.8 mg · g-1, the vitamin C is 35.69 mg·100g-1.5. The growth characters of strawberry of substrate formulas T1 (peatmoss: perlite=3:1) was the best. At this time, the plant height is 13.2 cm, the stem diameter is 2.8 mm, the stolen length is 26 cm, the number of stolen is 1.4, the area of leaf is 221.7 cm2. The highest production is 908.3 g. The content of acid is 0.873%, the vitamin C is 60.21 mg ·100g-1, the reducing sugar is 532.1 mg ·g-1.
