Why is Heilongjiang so cool and rich in rice?

Some modern rice varieties can adapt to cold weather and can also be planted in high latitudes. The land in Northeast China is fertile and rice is harvested once a year. Compared with two or even three crops a year in the south, the growth cycle is longer and the sugar content is higher. So it tastes sweet and is very popular in the market.

In the final analysis, agricultural technology is developing. Where rice could not be planted before, it can be planted now. Some time ago, Teacher Yuan Nongping's team even succeeded in sea rice. Is there anything strange about northeast rice? There will be sea rice in the future.
