Rice is an important support for China's food security. In terms of the current grain production capacity, it is difficult to supplement or replace other varieties of early rice, both in terms of planting area and output. For rice cultivation, the south can grow two crops a year, namely early rice and late rice.
Now with the improvement of people's living standards, more and more people do not only pursue rice yield, but the pursuit of rice taste, some people say that late rice is better than early rice, what is the reason? The following factors are inextricably linked:
First, the varieties are different. Early rice is generally indica.
The species of the work is tall and large. Early rice is sown in the spring and harvested in the summer. In the spring, the rain is relatively abundant, and the sun shines.
On the contrary, there are fewer rice planted at this time, and the growth of rice in the early stage is relatively slow. In rice flowering to knotting rice.
At that time, it is also the transition period of spring and summer when there is a lot of rain, and the rice sets ears at this time, and the rain often saturates the rice, so the rice planted will lack a lot of nutrients. After cooking, the grains of rice are loose, and they become pureed in the mouth, which is not sticky, and the taste is bland, and the taste is worse than that of late rice.
Late rice is generally planted in our country, which is mainly "hybrid", that is, hybrid rice.
However, late rice is usually sensitive to light, and when the days are getting shorter after the summer solstice, it induces flowering, a long growth cycle, more nutrient accumulation, full filling, and a better taste. As for what to plant, it depends on personal preference. No matter what the variety, the taste of late rice is delicate and soft, round and smooth, with a strong stickiness, and a faint sweet, soft and glutinous feeling.
Second, the growth cycle is different. The length of time determines the ripeness of the paddy. Generally, the growth period of early rice is 90-120 days, and that of late rice is 150 to 140-170 days.
As we all know, the more ripe the fruit in nature, the better it tastes, and rice is no exception. The variety of early rice is only suitable for growing before July, which is a matter determined by his unique character, leaving this time node it will lose the ability to grow and develop, so this time is only about 100 days, then its grains are difficult to ripen, so when harvesting early rice, there is still a faint green, which is not ripe, and the taste must be bad.
The growth cycle of late rice is about 140 days, more than a month longer than early rice, and it is the season of autumn when it is harvested.
So the higher the average temperature that the rice gets, the longer the light duration and the light intensity.
large, the more products of photosynthesis, the more abundant. The nutrients produced by photosynthesis in rice include starch, protein, and fat, to name a few. This is the main reason why late rice is better than early rice.
Therefore, the difference in varieties, seasons and growth cycles determines that early rice is not as delicious as late rice. In conclusion, the main reason why late rice is better than early rice is that the temperature and light are different during the planting process.

Late rice grows for a long time, has a good accumulation of protein, is more nutritious, and is a little more tasty. According to the different grain quality and harvest season, indica rice and japonica rice can be divided into two categories: early rice and late rice. As far as the same type of rice is concerned, in general, early rice has a large white belly and few grains, and the quality is worse than that of late rice.
Early rice rice is loose and has poor pressure tolerance, and it is easy to produce broken rice during processing, and the rice yield is low. On the other hand, late rice has solid quality, good pressure resistance, less broken rice during processing, and higher rice yield. In terms of the taste of rice, early rice is worse than late rice.
If the quality of the early and late rice is comparative, the quality of the late Indica rice is still better than that of the early Indica rice.
-
Early rice is more delicious because the growing period is relatively longer.
-
Rice and late rice are about the same, and they are delicious. Because they are all one variety of rice.

Early rice is a southern indica that has been cultivated earlier and matures early.
Medium-ripening rice is a medium-ripening type of rice that is seasonally between the early-maturing type and the late-maturing type. Late rice is rice that has a late transplanting stage or a late maturity stage.
The rice produced by early rice is called early indica rice.
or early rice, with poor taste, generally used as industrial grain or reserve grain.
Semi-late maturing rice is a medium-maturing type of rice that is seasonally between the early-maturing type and the late-maturing type. Generally mature in early autumn, most japonica varieties have medium photosensitivity, and the number of days from sowing to heading varies greatly depending on the region and sowing date, and the short days of high temperature weather are encountered.
The growth period is shortened. The photosensitivity of medium indica varieties is weaker than that of medium japonica, and the number of days from sowing to heading changes little and is relatively stable, so the adaptability range of varieties is wider, and late maturing and early indica in South China rice area are introduced to the Yangtze River Basin.
The rice area can be used for medium rice cultivation.
According to the growth period, sowing period, growth period and maturity stage: early rice, middle rice and late rice Hengdou. Generally, the growth period of early rice is 90 120 days, that of medium rice is 120 150 days, and that of late rice is 150 170 days.
Early rice generally has a larger belly white, fewer hard plasmids, loose rice quality, and poor quality, while late rice is better quality.

Summary. Hello dear. Early rice is a bit higher in sugar.
From the perspective of protein content, the protein content of early rice is generally higher than that of late rice. However, the protein content of early and late rice generally does not exceed 10%. Therefore, rice is not the main source of protein supplementation.
In general, there is not much difference in nutrition between early and late rice.
Hello dear. Early reed contains more than rice with a higher sugar content. From the point of view of the content of protein and old forest quality, the protein content of early rice is generally higher than that of late rice.
However, the white matter content of egg spine in early and late rice generally does not exceed 10%. Therefore, rice is not the main source of protein supplementation. In general, there is not much difference in nutrition between early and late rice.
The starch and sugar content in rice is relatively high, and if you eat early rice often, it is easy to cause blood sugar recurrence. Diabetic patients should pay attention to controlling fat and calorie intake in their diet, so they should try to eat less staple foods with high starch and calorie content.

Early rice: Southern indica rice with earlier cultivation time and early maturity, which is distinguished from middle rice and late rice according to different production seasons.
Late rice: Rice with a late transplanting stage or a late maturity stage.
First, the light sensitivity is different.
Late rice: the vegetative growth period is the longest (days) and can be shortened by short days and high temperatures, the shortest basic vegetative growth period, and the basic vegetative growth is also small.
Early rice: The vegetative growth period is the shortest (23 days) shortened by short days and high temperatures, but the vegetative growth is slightly greater than that of late rice.
Second, the temperature sensitivity is different.
The upper limit temperature of rice growth is generally 40, and the upper limit temperature of development will not exceed 28. Late rice is more sensitive to temperature than early rice.
3. The harvest time is different.
The growth period of a season of rice sown in early May is generally between 140-160 days, and the harvest time should be in early to mid-October; In the area of double cropping in one year, early rice is generally harvested in late July.
Late rice is generally harvested in mid to late October, and its varieties have different growth periods. As for the Hainan region with three seasons a year.
-
Early rice and late rice are the southern sayings mainly in Guangdong and other southern, where the four seasons are warm, and you can plant three crops, one season of wheat, and two crops of rice, so the first season of rice is early rice.
The second crop of rice is late rice.
The main reason is that the production time is different.
Late rice is delicious and fragrant. Early rice is too rough.
-
The time of early rice is long and can be stored for a long time, and the time of late rice is short, and it is not hidden.
-
The distinction between late rice and early rice: their main difference lies in the different climatic environments of the cultivation season, which forms different adaptations to the cultivation season. In the growing season of late rice, the temperature is from high to low, the day length is from long to short, the light is from strong to weak, and the wind and rain are from more to less, while early rice is just the opposite.
Early rice can be used as late rice, which is called turning autumn, and the growth period is shortened. The growth period of late rice and early rice is prolonged, which affects the planting of late rice and is generally unusable. There seems to be a typhoon in northern Zhejiang in July, which can be referred to as follows:
Early rice was sown before April 5, and medium rice was better in mid-May. Late rice around June 10. Medium rice is one season, and early and late rice can be cropped in two consecutive crops.

The taste of rice is directly related to the nutritional content and structure of rice. The nutritional structure and composition of rice are closely related to the growing environment. The planting environment includes factors such as soil texture, fertilizer, moisture, temperature, light intensity, and geographical location.
Therefore, the formation of rice nutrient structure and composition has a greater and more direct relationship with temperature and light intensity, and has a deeper impact. Generally, the growth period of early rice varieties is slightly shorter, and the average temperature obtained during the whole growth period is lower than that of late rice, and the light time is shorter and the light intensity is weaker. This leads to a considerable difference in the nutritional structure and composition of Maosheng early rice and late rice, which is also the main reason for the difference in taste.
The higher the average temperature of rice, the longer the light time, the greater the light intensity, and the more abundant the photosynthetic products. The nutrients produced by rice photosynthesis include starch, protein, fat, etc. The higher the average temperature, the longer the light time, the greater the light intensity, the less amylose, the more amylopectin, the more protein, the more amino acid types, the more fatty acid types and contents, the better the taste of rice; Conversely, the worse the taste.
This is the main essential reason why late rice is better than early rice.

Summary. Answer; Hello kiss Hello rice is delicious early rice or late rice is delicious Generally speaking, late rice is more delicious and the varieties are different: early rice is generally planted with indica rice, the plant of this rice is taller and larger, and late rice is generally planted with "heterogeneous", that is, hybrid rice.
The growth cycle is different: under normal circumstances, the growth period of early rice is 90-120 days, and the growth cycle of late rice is about 140 days. Different levels of sensitivity to light:
Early rice is not sensitive to light, and late rice is sensitive to short days.
Answer; Kiss hello Large-scale rice is good for early rice or late rice for hidden burning Generally speaking, it is more delicious late and the varieties are different: early rice is generally planted with indica rice, and the plant of this rice is higher and the stove rent is empty, and the late rice is generally planted with "heterogeneous", that is, hybrid rice. The growth cycle is different:
In general, the growth period of early rice is 90-120 days, and the growth cycle of late rice is about 140 days. The sensitivity to light is different: early rice is not sensitive to light, and late rice is sensitive to short days.
Generally speaking, late rice is more delicious. Early rice generally has loose rice quality and poor pressure resistance, and it is especially easy to produce broken rice during processing, and the rice yield will be relatively low. Late rice is solid in quality, very good in pressure resistance, and broken rice will be high in processing, with little hunger and rent, and the rice yield is relatively high.
And in terms of the taste of rice, early rice is much worse than late rice. 2. The time to harvest rice in different seasons is also different, for example, in the middle and lower reaches of the Yangtze River in China, early rice is generally sown from the end of March to early April, and it can be harvested in July, medium rice is generally harvested in mid to late September, and late rice is generally harvested in early to mid-October. 3. Harvesting rice can also be determined according to rice plants, ears and seeds.
When most of the rice plant color turns yellow, you can harvest, if the rice ear from green to yellow, start from the middle, slowly the whole rice ear will turn yellow, generally rice seeds turn yellow and hard when Qi Zhao, it also represents full maturity.
Wearing cloth shoes to plant rice, no need to irrigate to harvest rice, this myth that sounds like a fantasy, now in the hands of scientists has become a reality, and in China's Anji orchards, Fuyang mountains, Guangxi arid areas, Beijing Qinhuangdao and other places to obtain a large area of harvest, the average yield per mu is 400 kilograms, this magical cultivated rice is a wonderful flower in the rice garden - upland rice. This is a paddy field with abundant grains and neat straws....This is the masterpiece of the Shanghai Agricultural Biological Gene Center, which has bred a new upland rice variety "Zhonghan No. 3", which has become the first batch of new upland rice varieties approved by the whole country in China. >>>More
