To explore the phenological characteristics of Polygonum viviparum introduced from high altitude to low altitude area.
To introduce the root and seed of Polygonum viviparum from high altitude to low altitude area and collect their growth and phenological data.
In low altitude area, Polygonum viviparum germinated at the beginning of March, grew from March to the end of July, withered during the whole August due to high temperature, recovered from the end of August to the beginning of October, and then withered again due to low temperature. Its reproduction lasted from April to the end of July, stagnated from the beginning of August to the middle of September, and recovered from the middle of September to the end of October.
The high temperature of August in low altitude area is the bottleneck season for Polygonum viviparum, yet it can grow normally while such technologies are applied to its culture as early seeding, culture seedling with fertilizing soil ball, complete overshadow etc.
探究从高海拔地区引种至低海拔地区的珠芽蓼的物候特征。
将珠芽蓼的根和种子从高海拔地区引种至低海拔地区，并收集其生长和物候数据。
在低海拔地区，珠芽蓼于3月初萌发，3月至7月底生长，8月因高温整月枯萎，8月底至10月初恢复生长，随后又因低温再次枯萎。其繁殖期从4月持续至7月底，8月初至9月中旬停滞，9月中旬至10月底恢复。
低海拔地区8月的高温是珠芽蓼生长的瓶颈期，但采用早播、带肥土球育苗、全程遮荫等栽培技术，珠芽蓼可正常生长。
