What month to plant rice in the northeast?

Northeastern rice 1 year 1 season, because of the cold weather in the northeast, often low temperature cold, winter rice survival rate affected, so the northeast rice is generally only planted 1 season.

The Northeast rice area is located in the Liaodong Peninsula, north of the Great Wall, east of the Daxinganling, including Heilongjiang, Jilin province and most of Liaoning province and northeastern Inner Mongolia.

The confluence of the three river plains of the Songhua, Heilongjiang and Ussuri rivers is the core production area of the Northeast Rice Region, which is suitable for rice growth. ?

A, Northeast rice a few seasons a year ?1, Northeast rice 1 year 1 season. Due to the cold weather in the northeast region, often low temperature cold, so the survival rate of rice in winter will be greatly affected, so the northeast rice is generally only planted 1 season. North China is a single-season rice in the north, need to be sown before Qingming, transplanted in late April to early May, if conditions allow, can also be transplanted in the rainy season. ?2, the northeast rice area is mainly located in the Liaodong Peninsula, north of the Great Wall, east of the Daxinganling, which includes Heilongjiang, Jilin province and most of Liaoning Province and northeast Inner Mongolia. Liaoning Province, a **** there is the Liaohe Plain, southeast coast, Liaodong Cold Lang mountainous area and west of Liaosi low hills 4 rice areas, including the Liaohe Plain rice area is the largest, about 7.001 million acres of rice, the level of yields is also higher, generally in this case, the acreage of production up to about 500 kg. ?3, the core production areas of the Northeast rice are Songhua River, Heilongjiang River, Ussuri River, the confluence of the three river plains, more suitable for rice growth. The land in the Northeast is the most nutrient-rich black soil in the soil category, and it can provide sufficient nutritional conditions for rice growth. Since the Northeast has a half-year-long cold winter, it largely reduces the occurrence of pests and diseases, and there is sufficient light in the fall, with a large temperature difference between day and night, which is conducive to the accumulation of nutrients in Northeast rice.

Two, the northeast rice when to start planting ?1, the northeast rice for the early single-season rice, generally in the early to mid-April each year for sowing, but the specific sowing time should be decided according to the local climate. Northeast early single-season rice rice crop area is located in the Liaodong Peninsula, north of the Great Wall and east of the Daxinganling, although the Northeast region has four distinct seasons a year, but its spring and summer is relatively short, rice needs a longer time to accumulate temperature and receive sunshine, so the growth cycle of the Northeast rice is generally in the 200-240 days or so. ?2, before planting rice must first turn the soil of the paddy field 1 time, this process is mainly divided into rough plowing, fine plowing and cover leveling, the former farmers usually use water buffalo for land preparation, now basically use machines.

The seedlings are raised by spreading rice seeds and then sprinkling 1 layer of rice husk ash on the soil. Most of the seedlings are now cultivated in nursery centers, and good rice seedlings are the key to successful planting. After the seedlings have been cultivated, they can be inserted into the paddy field. The traditional method of inserting rice seedlings usually uses rice ropes, rice markers or rice-planting wheels. 3, before planting rice should be preferred disease-resistant seeds, selected disease-free robust rice seeds, before the pharmaceutical treatment will be about 2-3 days of drying, which can reduce the source of bacteria and increase the vitality of the seed, improve the germination rate, germination potential. Then use the appropriate fertilizer for seed mixing, you can use 5% deep sea polysaccharides, dilute it 300-500 times, use 1 time can be, this can make the rice germination rate is high, germination Qi, improve the effectiveness of the drug, fertilizer effect.
