施利康解硅菌剂肥对膜下滴灌水稻发育阶段生理性状的影响

Effect of Mulched Drip Irrigation by Silicon Bacterial Fertilizer "Shilikang" on Physiological Characters of Rice Development Stage

为探明施利康解硅菌剂肥对膜下滴灌水稻发育阶段生理性状的影响,本研究选取4个适宜膜下滴灌水稻栽培的品种进行试验。通过对它们在施用硅肥与对照5个发育时期株高、叶绿素含量以及净光合速率的调查与测定,结果显示:施用"施利康"解硅菌剂肥可正负调节膜下滴灌水稻的株高,可以扶壮弱苗,限制旺苗;还可以提高水稻植株的叶绿素含量,并将之稳定在一个高位范围,防止叶片的早衰;最后可以显著增强膜下滴灌水稻剑叶的净光合速率,而且还能改善水稻弱苗的光合能力。

Selecting four rice varieties which suitable for mulched drip Irrigation to discuss effect of mulched drip irrigation by silicon bacterial fertilizer ＂Shilikang＂ on physiological characters of rice development stage. By survey and determinate plant height of developmental stage, chlorophyll concentration and net photosynthetic rate, the result indicated that using ＂Shilikang＂ can adjust plant height and seedlings, it also can increase chlorophyll concentration of plants and will be stable it in a high range to prevent leaves from early aging. Then it can significantly enhance the net photosynthetic rate and improve photosynthetic capacity of weak seedling.
