Abstract: Studies on the Optimum Cultivar and Intercropping Date of Garlic
Intercropped with Substrate Culture Tomato Under Plastic Tunnel
In order to select the best garlic cultivar and intercropping date for garlic intercropped with
substrate culture tomato under plastic tunnel，an experiment was conducted with split plot design during
the year 2011—2012 at the experimental research station of Northwest A & F University. The tomato
（called Difenni）was plated on 31st July 2011. During the growth of the tomato，two factors studied in this
experiment were three intercropping dates（09–01，09–21 and 10–11）as main plots and three garlic
cultivars（namely‘Zhengyue Zao’，‘Caijiapo Hongpi’and‘Gailiang Suan’）which have different maturity
dates as sub-plots. The data were recorded on sprouting of garlic，survival rate of plant，bolting rate，
characteristics of bulb and yield of tomato，which was planted on 30th March 2012. The experimental
results showed that the sprouting for 09–01 was much longer than that for 09–21 and 10–11，but the
sprouting date for 09–01 was much earlier than that for 09–21 and 10–11. The bulb characteristics of
‘Gailiang Suan’were significantly higher than that of‘Caijiapo Hongpi’and‘Zhengyue Zao’. The survival
rate of plant on 10–11 was higher than that on 09–21 and 09–01. The bolting rate was different with
different garlic cultivar and intercropping date. Intercropping showed significant effect on spring tomato
and intercropping with‘Gailiang Suan’significantly decreased the yield of tomato. Intercropping with
‘Zhengyue Zao’at 09–21 produced a highest net income. Therefore，‘Zhengyue Zao’and 09–21 are
recommended as a suitable cultivar and intercropping date for tomato/garlic intercropping in substrate
cultivation under plastic tunnel.
