The conditions for the cultivation of sea rice should be planted in saline-alkali soil.

Sea rice needs to be planted in saline-alkali land, and the growth process does not need to be sprayed with pesticides, and the growth climate is similar to that of rice, and it needs to be irrigated with salt water of 6% salinity, which has the characteristics of drought and waterlogging resistance. it can be planted in semi-desert inland saline soil, eastern coastal saline-alkali land, northeast Songnen plain saline-alkali land and so on.

I. conditions for planting sea rice

The main results are as follows: 1. Seawater rice is suitable for planting in saline-alkali soil, but there are very broad saline-alkali land in China, which do not need to spray pesticides in the growth process.

2. It can be planted in semi-desert inland saline soil, coastal saline-alkali land in the east and saline-alkali land in Songnen Plain in Northeast China.

3. The growth climatic conditions of sea rice are more or less the same as those of rice, and it is easier to grow than rice.

4. Sea rice does not grow directly in the sea, but irrigates 6% salinity salt water when planting.

5. It has good drought and waterlogging resistance, and does not need to grow in high-temperature and humid soil.

II. Brief introduction of Sea Rice

In fact, sea rice is the visual name of saline-alkali tolerant rice, which grows in saline-alkali land such as seaside and tidal flat. It does not grow in sea water or in the sea, but can be soaked in sea water for a short time, and the beach is a necessary place for sea water rather than sea water.

There are 950 million hectares of saline-alkali land in the world, 320 million hectares in Asia and 1.5 billion mu in China, of which 280 million mu have been developed and utilized. China can use these 200 million mu of saline-alkali land to grow sea rice. According to the estimated yield of 200-300 kg per mu, it can increase its yield by tens of billions of kilograms and supply more than 200 million people.

As early as more than a hundred years ago, a large number of Korean refugees planted rice on the saline-alkali land along the coastal beach of Panjin, Liaoning Province. The real large-scale and modern cultivation of rice began with the Yingtian Co., Ltd., which was founded by General Zhang Xueliang in 1928.

In 1986, Chen Risheng began to study and popularize it in Zhanjiang City for a long time. Yuan Longping's participation in the research raised the degree of attention to the related work.

In the autumn of 2016, the highest yield of sea rice planted by Jiang Huilong in Hepu Town of Ningbo was about 600 kg per mu and the lowest was about 500 kg.

In the autumn of 2017, the highest yield of sea rice per mu was nearly 620.95 kg at the Qingdao Rice Research and Development Center chaired by Yuan Longping.

Large-scale trial planting was carried out in five types of saline-alkali land in China in 2018.

On July 22, 2018, more than 80 rice varieties, including "sea rice", planted by Yuan Longping matured in batches, which is a major good news for the Qingdao Rice Research and Development Center.
