木豆是紫胶虫的主要寄主树之一,也是紫胶虫越冬保种的一个优良寄主.在紫胶生产中,以采用的木豆树都是靠人工栽培的,因此,弄清木豆的合理施肥方法对紫胶生产是有意义的.这次试验的内容主要分三个方面:1.磷肥的施用量和施用方式;2.氮肥(硫酸铵)、有机肥(猪粪)、草皮泥和磷肥(钙镁磷)的单独施用以及各者分别与磷肥配合施用的效果; Pigeon is one of the main host trees of the lac insect and is also an excellent host for the overwintering conservation of the lac insect.In the production of lac, the pigeons are all cultivated by artificial cultivation, The reasonable fertilization method is of great significance to the production of shellac.The contents of this experiment are mainly divided into three aspects: 1. The application rate of phosphate fertilizer and the application mode; 2. The nitrogenous fertilizer (ammonium sulfate), organic fertilizer (pig manure) Mud and phosphate fertilizer (calcium magnesium phosphate) and the individual application of phosphate fertilizer alone with the effect;
