Is it better to grow rice on dry land in the mountains or rice grown in paddy fields

Rice planting, transplanting and water seeding in paddy fields, and dryland planting is rice drying. The difference is still relatively large. Transplanting and transplanting rice is the most common and widespread way of growing rice.

Adopt the method of raising seedlings in greenhouses or paddy fields, and enter Honda when the seedling age is suitable.

Transplanting. The advantages of this method are high yields, stable yields, resistance to stress and resistance to adverse weather conditions. But the disadvantage is also obvious, that is, the cost is high, especially the labor cost.

Especially in the current stage when rice is not strong, the shortcomings of rice transplanting and transplanting are becoming more and more obvious.

1. The efficiency of dry-seeded rice is high, and the technical operation eliminates the need for multiple processes such as pulping and watering, and can be prepared on dry land when there is no water, and the daily sowing can even reach hundreds of acres. 2. It is conducive to high yield, rice stubble is generally a dryland crop, which has high requirements for soil permeability, paddy field needs pulping to improve water retention, rice needs a relatively long drying time after harvesting, it is easy to miss the best sowing date of crops, especially wheat, and the soil permeability is good, which can improve the yield of wheat under stubble by 50-100 catties. 3. Reduce the occurrence of diseases, due to the low humidity in the field, the occurrence of diseases in dry rice is significantly lower than that in pure paddy fields.

Rice is planted in paddy fields, because the whole growth period of rice should be dry and wet, and the fertilizer is sufficient and more suitable for absorption, so the whole plant grows evenly, the rice is large, and the particles are many and full and round. When processed into rice, the taste is better than that of rice on dry land. Rice ears can reach about 120 to 140 grains.

So the yield is definitely better than that of dryland farming.

It must be rice grown in paddy fields that is good. But you should grow in paddy fields, why is it called rice? If it grows badly in dry land.

Of course, rice grown in paddy fields is good, but dryland rice is hard to cook and has a bad taste, and the yield of dryland rice is relatively low.

Upland rice is good, not because rice is called rice, rice is good, rice also has upland rice, and the taste and nutritional value are much better than rice, but because rice is good and has a high yield, it is popular. There is still upland rice growing in Laos, and after eating it there for two months, it really tastes like rice.

I've eaten it, and it's still good for dryland rice.

Upland rice is also called upland rice, and its biological characteristics, external morphology and internal anatomy are similar to rice, such as upland rice also has a fissed aeration tissue suitable for swamp growth, which is connected by roots and stomata through stems and leaves to absorb air to supplement the lack of oxygen under flooded conditions. Therefore, it can be considered that upland rice is an evolved rice type from rice and is suitable for dry farming. The biggest difference between upland rice and rice is that upland rice is suitable for cultivation and cultivation under completely dry field conditions, as long as the soil contains a certain amount of water, it can grow well.

At present, upland rice is cultivated in many countries around the world, especially Brazil, which is known for its large cultivation area and high yield. It is also cultivated in China's Yunnan-Guizhou Plateau and northern rice areas. But the yield is relatively low compared to rice.

Rice is a kind of herbaceous rice, which belongs to cereals, and it is also the most important and oldest kind of grain in the rice genus, which is different from upland rice. Rice is native to China and India, and was cultivated by the ancestors of the Yangtze River valley 7,000 years ago.

The fruit of rice is rice, and the rice is called brown rice after removing the glume husk, and the brown rice can be obtained by grinding off the rice bran layer.

Upland rice is also called land rice. It is an eco-type crop formed by the long-term domestication of rice in dryland conditions without aquifer. It is suitable for cultivation in dry land, and can also be planted in paddy fields or depressions, mainly distributed in dry land, hillside land with stable rain in summer but lack of irrigation conditions, or low-lying areas that are dry in spring and prone to flooding in summer and autumn.

Rice is relative to upland rice, upland rice produces millet that is very similar to rice, but the yield is generally lower, and the rice is slightly smaller, rice is planted in paddy fields, and upland rice is planted in the ground.

Courseware Cultivated rice is generally called rice Even Wikipedia "rice" is directly to the entry "rice" The most basic division is often distinguished according to the conditions required for rice growth, that is, water irrigation, so rice can be divided into rice and upland rice. However, most of the institutions that study rice cultivation are aimed at rice, and the proportion of upland rice is relatively small. Latin is the Latin for cultivated rice, and there is no direct division, they are a species, according to the differentiated type of rice

There are two kinds of cultivated rice: indica rice and japonica rice, each of which is divided into early, middle and late three, and each is divided into two kinds of rice and upland rice (i.e., upland rice), each of which is divided into sticky rice and glutinous rice, and if you want to subdivide it, there are 23 species, all of which are of the genus Oriza, with different species names.

One doesn't need a water environment, and one needs a water environment.

Indeed, there was a kind of upland rice earlier, and the rice that was ground out was called japonica rice, and in the past when rice was in short supply, japonica rice was a good choice for people, it did not have the rice that was ground out of rice, and it did not have the taste of rice, and even no rice to carry hunger.

But japonica rice is not useless, compared to the low planting cost of this kind of rice, short maturity time, good management, labor and labor saving and no water, etc., the main disadvantage is low yield, low income.

Rice: Native to tropical Asia, rice was widely cultivated in China and gradually spread to other parts of the world.

Upland rice: upland rice, drought-tolerant, cultivated rice suitable for dryland planting, also known as upland rice, generally refers to cultivated rice that can adapt to grow in boundless dryland, slope land and arid ecological environment, and is a variant of rice.

Which is harvested earlier or upland rice, this early depends on what variety you buy early or late, but there is a little upland rice that is definitely not as delicious as rice rice.

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.

The breeding of upland rice varieties will be an innovation in the history of rice cultivation for China, which has more than 1 billion mu of dry land, and will be of great agricultural strategic significance. Cultivated rice is actually a big family, with many brothers and sisters, and they have different forms.

First, the personality is different, rice and upland rice are one of the members, the biggest difference between them is the dependence on water, rice is much more dependent on water than upland rice. However, in life, people know far less about upland rice than about rice, and upland rice seems to be forgotten in the corner. However, in the face of severe global water scarcity, the drought resistance of upland rice has provided a tremendous impetus for a new path in food production.

At present, the irrigation water consumption per mu of paddy field is 700-900 cubic meters, and if high-yield and high-quality drought-resistant varieties are planted, only about 200-300 cubic meters per mu are needed. Each mu can save 500-700 cubic meters of water, and if 10 million mu of high-yield drought-resistant rice is promoted in irrigated paddy fields across the country, 50-7 billion cubic meters of water can be saved. As we all know, the rapid increase in rice yield in a certain period of time is due to the application of hybrid rice technology by Chinese scientists.

At present, in China's new drought-resistant rice variety "Zhonghan No. 3" has been bred, and the next step is to popularize the work throughout the country, and China's scientists are very optimistic about the development prospects of upland rice.

In general, there is still a certain gap between the quality of upland rice and the quality of rice, and the whole rice rate, imperfect grain and chalky are the main quality indicators of upland rice. Chalkiness and whole rice rate have a great direct negative effect on upland rice yield, which is a difficult point in improving the quality of upland rice.

The most basic rice requires more water than upland rice.

If it is some arid areas, you must choose the former, if it is relatively rich in water, you must try to choose the latter.

Upland rice in the north is better than rice in the south, because the rice in the north is mostly one-season rice, which grows for a long time, and the starch amylopectin in the rice is high, and the viscosity is chewy.

The temperature difference between day and night is large, and the fragrance and sweetness produced are good.
