近年来,我省各地正在引种栽培川楝。但是,由于它内果皮坚硬发芽困难,出苗不整齐,不利于培育壮苗。为此,我们进行了不同水温浸种催芽试验。一、试验方法供试验的川楝核果由成都调来,核果大小基本相同。以随机抽样法分为8个组合,每组20粒,重复两次。于1977年3月10日用50℃温水为始温,每隔10℃为一梯度进行浸种处理。自然冷却后连续浸泡3天,并用室温水和干核果作对照。在3月16日播种,按常规育苗技术进行管理。从开始发芽起,每隔5天统计发芽数一次,
In recent years, the province is introduced and cultivated Chinensis. However, due to its hard germination inside the pericarp, emergence is not neat, is not conducive to nurturing strong seedlings. To this end, we conducted a different temperature soaking germination test. First, the test method Chrysophyllum drupe for the test transferred from Chengdu, drupes size is basically the same. Randomly divided into eight sample combinations, each 20, repeated twice. On March 10, 1977 with 50 ℃ warm water for the initial temperature, every 10 ℃ for a gradient soaking treatment. After natural cooling, soak for 3 consecutive days, with room temperature water and dried drupe as controls. Sowed on March 16 and managed by conventional seedling raising techniques. From the beginning of germination, germination number once every 5 days statistics,
