To study the growth rules, the output and the influence factors of cultivated Phyllanthus urinaria, and provide basis for standardized cultivation.
Orthogonally designed field experiments with three factors and three levels, comparing the characters of cultivated plants and the wild ones of P. urinaria.
Under the manual planter condition, the characters, such as branching number, single dry weight, single output etc, enhanced enormously, and the increase of single output reaches 3.27 times. The sowing time was the most sensitive factor, which affected the single character and the yield per unit of area, whereas the different levels of sowing thickness and fertilizer also remarkably influenced the output. When the seeds were sowed at the mid-April earlier period, drilling with the 20 cm row spacing, they started to emerge about 1 week later, the growth flush period was from June to August, the growth slowed down in September, and the output per hectare could reach to 5.750 kilograms at harvest in late October.
研究栽培叶下珠的生长规律、产量及影响因素，为规范化栽培提供依据。
采用三因素三水平正交设计田间试验，比较栽培叶下珠与野生叶下珠的性状。
在人工种植条件下，叶下珠的分枝数、单株干重、单株产量等性状大幅提高，单株产量增幅达3.27倍。播种时间是最敏感因素，影响单个性状和单位面积产量，而不同播种厚度和施肥水平也对产量有显著影响。4月中旬早期播种，行距20厘米条播，约1周后开始出苗，6-8月为生长旺盛期，9月生长减缓，10月下旬收获时每公顷产量可达5750千克。
