  The effect of germination hastening,sowing materials and the kinds of fertilizer on exephant-foot yam yield was studied in 6 experimental sits of Qinling mountain region during 1993～1994. The results showed that the germination hastening in 13～20℃ for 15 days could yield 5.9%～22.2% higher than non-hastening and whole-tuber material used as seeds was best,and cutting-tubers with main bud was slightly better than cutting-tubers. Applying 2kg manure+0.2kg phosphorous fertilizer per stalk gave same yield as 1.0...

  By means of quadratic rotational combination design,a three-factor (N. P. K) experiment was conducted in a solar greenhouse. With the aid of computer,the mathematical models of the relationship between N. P. K and the effects on the yield and quality fo tomato were established. The results showed that N had a biggest effect on yield and quality of tomato,while the interaction between N. K is the most significant,and that the application rate of N. P. K all influence tomato s quality.

  Efficiency of hybridization of three pollination methods in bean was compared in greenhouse and plastichouse. The results show that protruding stigam without emasculation was the best in terms of hybridization percentage and number of seed set. More pads and seeds were obtained in greenhouse than that in plastichouse.

  Seed soaking time had a significant effect on germination of waxgourd‘Yichuanling’. Germinating potential and germination percentage decreased rapidly with seed soaking time. But high germinating potential and germination percentage were observed for the seeds without soaking treatment. The seed moisture only could be saturated 48 hours after both treatments of soaking and directly sowing on germination bed.
