试验选用高产中熟蕃茄品种苏杭6号(简称A品种)及抗性较强,茎秆粗壮,产量较低蕃茄BF兴津101号(简称B品种)进行土培试验,探讨不同品种蕃茄生育特性及根系活力对土壤养分吸收的差异。结果表明A品种吸收的总养分量高于B品种,且70%—90%的养分输送到果实中去,而B品种输送到果实的养分只有30%—60%。A品种根系活力较B品种强,吸收土壤速效钾量大于B品种。B品种根量较A品种大,吸收土壤非交换性钾量占总吸收钾量的比例比A品种高。在富钾的土壤上对吸收速效钾能力强的蕃茄品种增施钾肥,效果不显著。
In the experiment, tomato varieties BF-Jin-101 (referred to as B variety) with high yield and medium maturity tomato variety Suhang-6 (referred to as A variety) and strong resistance stalks with low yield were selected for soil culture test. Differences in Characteristics and Root Vigor of Soil Nutrients Absorption. The results showed that the total amount of nutrients absorbed by the A variety was higher than that of the B variety, and 70% -90% of the nutrients were transported to the fruit while the B variety was only 30% -60% of the nutrients delivered to the fruit. The root activity of A variety was stronger than that of B variety, and the available potassium content in soil was greater than that of B variety. B varieties than A varieties of large roots, the absorption of soil non-exchangeable potassium content of total absorption of potassium than the A variety of high. In potash-rich soil, the effect of applying K fertilizer to tomato varieties with quick available potassium was not obvious.
