  The experiment on effect of soil water on blotchy ripening in tomato fruit was conducted with variety Jiafen No.10 in greenhouse. The results indicated that incidence and index of blotchy ripening in tomato fruit were increased at high level of soil water (>16%) for a long time,and high level of water in soil could result in underdeveloping of roots and decreasing of root activity.

  The line P 1168 with parthenocarpy of cucumber sets fruit well without pollination,the daily increased values fruit weight (FW),fruit length (FL) and fruit size (FS) of P 1168 with pollination or unpollination are 23.64g,27.88g;2.33cm,2.72cm;0.61cm 3,0.65cm 3 respectively. The fruits of UP 3315 with nonparthenocarpy stop growing 3 days after anthesis,and then can get no yield. The contents of carbon and nitrogen of fruit increase rapidly with the fruit development. There is positive correlation between...

  The effect of plastic house and plastic film mulch on ginger’s growth and yield was studied. The result indicated that the ginger plants cultivated in plastic house broke the earth earlier than the control,had larger growth quantities,higher rate of leaf strentching,higher and stronger shoots and more branches,also gave more accumulation of dry matter and higher yield. The ginger mulched with plastic film in plastic house grew best and had the highest yield amoung the three treatments.
