Water bamboo is a thermophilic plant, with a suitable growth temperature of 10-25°C, and is intolerant of cold, high temperature and drought. Double-season wild rice is mostly planted in plain areas. Double-season wild rice has loose requirements on the length of sunshine and high requirements on water and fertilizer conditions. Temperature is an important factor affecting the growth of wild rice. Wild rice has a well-developed root system and requires a lot of water. It is suitable for clay loam or loam with sufficient water sources, easy irrigation, deep and soft soil, fertile soil, rich in organic matter, and strong water and fertilizer retention capabilities.

There are two types of wild rice: single-season wild rice produced in autumn and double-season wild rice produced in autumn and summer. Both are propagated by divisions. Single-season wild rice in the Yangtze River Basin is planted in separate piers from Qingming to Guyu. Summer and autumn double-season wild rice can be divided into spring and autumn. Spring is planted before and after Guyu, and autumn is planted before and after Beginning of Autumn.

Wild rice can be divided into four stages:

(1) Germination stage begins in March and April after spring. The minimum temperature is above 5°C, preferably 10 to 20°C. .

(2) The tillering stage is from late April to the end of August. Each plant can produce more than 10 to 20 tillers, and the suitable temperature is 20 to 30°C.

(3) During the pregnancy stage, double-season wild rice gestates once from early to late June and again from late August to late September. Single-season wild rice plants only germinate from late August to early September, and the suitable temperature is 15-25°C. If the temperature is lower than 10°C or higher than 30°C, wild rice won't germinate.

(4) During the growth stagnation and dormancy stage, when the post-pregnancy temperature is lower than 15°C, the growth of tillers and above ground will stop, and below 5°C, the aboveground parts will die, and the underground parts will overwinter in the soil.
