以2种含不同体积的腐熟花生壳为育苗基质,2种控释肥为研究对象,研究了基质中添加不同种类和不同用量控释肥对番茄育苗效果的影响,以期筛选出适合育苗的基质配比和控释肥种类及用量。结果表明:与对照(不掺肥)相比,在S1和S2基质中,CRF-A3处理(即N 540mg·L~(-1),P_2O_5270mg·L~(-1),K_2O 540mg·L~(-1))的番茄幼苗在株高、茎粗、地上部干质量和叶绿素含量上差异显著,并优于其它处理,且在S2(V/V)=5∶4基质中综合表现最好,株高和茎粗分别比对照增加83%和14%,壮苗指数达到0.231。
Two kinds of matured peanut shells with different volumes were used as seedling substrates and two kinds of controlled release fertilizers. The effects of adding different types and dosage of controlled release fertilizers on the growth of tomato seedlings were studied in order to screen out suitable substrates for seedling raising Proportion and controlled release fertilizer types and dosage. The results showed that CRF-A3 treatment (ie N540mg · L -1, P_2O_5270mg · L -1, K_2O 540mg · L -1) in the S1 and S2 matrices compared with the control (-1)) of tomato seedlings showed significant difference in plant height, stem diameter, aboveground dry weight and chlorophyll content, and was superior to other treatments and showed the best overall performance in S2 (V / V) = 5: 4 , Plant height and stem diameter increased by 83% and 14% respectively compared with the control, seedling index reached 0.231.
