| Abstract: | Several factors causing chlorosis of hawthorn were preliminarily summed up from imvestigations: The pattern of its occurrence and development,its pathogeny and its negative effect on hawthorn production. Obvious effect can be seen by using the new-developed ferrous nitrofulvate which is highly effective,cheap and convenient to store and transport. The cure rate of chlorotic plants is 40%-87%. The number of chlorotic plant of 3rd-rate was reduced by 360%-100%. The chlorophyll content was increased by 64%-224%. The yield per tree treated was 25% higher than that of control. The contents of sugar, acid, fruit gum, Ca and Fe element in the fruit were also increased,and quality of the fruit was improved. |
