The invention relates to the technical field of planting, in particular to a rhodomyrtus tomentosa planting method. The method mainly comprises the following steps that (a) seed screening is performed, wherein high-quality rhodomyrtus tomentosa seeds are screened and dried and then are stored; (b) the seeds are processed, wherein the seeds are put in a saline solution for screening, and seeds obtained after soaking are uniformly mixed with silt; (c) transplanted seedlings are cultivated, wherein the seeds are scattered onto nutrient soil on a compartment face, a layer of straw is laid, and watering is performed to obtain the transplanted seedlings; (d) transplantation and planting are performed, wherein planting holes are formed, quick lime and planting base fertilizers are scattered in the planting holes, soil is backfilled, the transplanted seedlings are taken for transplantation, earthing is performed, a leaf fertilizer is sprayed on time within 2 months after transplantation, non-survived transplanted seedlings are supplemented in time to obtain survived transplanted seedlings; (e) field management is performed, wherein main seedlings are removed to promote side branch growth,and a pollination agent is sprayed in a flowering phase; (f) fruits are harvested. By adopting the method, the survival rate of planted rhodomyrtus tomentosa can be remarkably improved, the quality ofrhodomyrtus tomentosa fruits can be improved, the yield per unit area can be increased, and the economic benefit of planting is increased. The method is suitable for large-scale planting.

The invention relates to a citrus tree retaining preservative containing amino-oligosaccharin and cinnamic acid. The citrus tree retaining preservative is prepared from, by weight, 2-5% of amino-oligosaccharin, 1-3% of tea polyphenol and 1-3% of cinnamic acid, and the weight ratio of amino-oligosaccharin to tea polyphenol to cinnamic acid is (2-5):(1-3):(1-3). The fruit drop rate of citruses during tree retaining can be obviously reduced, and adverse influences of decrease of the next-year fruit setting rate caused by tree retaining preservation can be relieved.
