紫胶虫寄主以灌木生长较快投产较早。但大多数灌木寄主的开花结实率较高,花果期较长,消耗大量的无机元素,直接和间接地影响着寄主植物营养器官中碳水化合物、氨基酸等有机物质的合成与运输,从而影响到紫胶虫的生长发育和泌胶状况,且常常导致寄主树本身的生势下降,过早出现衰老,缩短使用寿命。本研究结果表明:应用乙烯利(0.3％)和尿素(2％)的混合水溶液喷洒花蕾,可抑制开花结实,刺激萌芽更新,增多侧枝,从而可提高冬代种胶的产量和质量,缩短寄主轮歇期。人工剪除花蕾,也有利于种胶产量和质量的提高。
The lac insect host grows faster with shrubs earlier. However, most of the shrub hosts have higher flowering and fruiting rate, longer flower-fruiting period and consume a large amount of inorganic elements, which directly and indirectly affect the synthesis and transport of organic substances such as carbohydrates and amino acids in the vegetative organs of host plants, thereby affecting The larval growth and development and secretions, and often lead to the host tree itself, the potential decline, premature aging, shorten the service life. The results showed that spraying the mixed buds of ethephon (0.3%) and urea (2%) could inhibit flowering and fruiting, stimulate sprouting and regeneration, and increase the number of lateral branches, thus improving the yield and quality of winter glum glue and shortening the host Turn-off period. Artificial cut buds, but also conducive to the increase of seed yield and quality.
