1. Different categories: Wheat is the collective name for wheat plants, which belongs to monocotyledonous plants and is a gramineous plant widely planted around the world; rice is herbaceous rice A species of the genus Oryza, which has been used as food for the longest time and is the most important species in the genus Oryza. 2. Different shapes: Wheat stalks are upright, clustered, and have a square and round base. The stems, leaves, and shriveled seeds of the plant can be used for medicine; rice belongs to the fibrous root system, and the ears are cone-shaped inflorescences, which are relatively loose and hang down when mature. 3. Different environments: Wheat is a long-day crop. If the light conditions are insufficient, it will not bear fruit; rice likes high temperatures and does not have high soil requirements.

1. The difference between rice and wheat

1. Different categories

(1) Wheat is the general name for wheat plants, which belongs to monocotyledonous plants. Gramineae are widely grown around the world. After a long period of development, they have become one of the food crops with the widest distribution, the largest area, the highest total output, the largest trade volume, and the highest nutritional value in the world. Wheat is one of the three major cereals and is an annual or biennial herbaceous plant. It is divided into winter wheat and spring wheat according to the sowing period. my country mainly produces winter wheat.

(2) Rice is a herbaceous species of the genus Oryza and a cereal. It is the oldest and most important type of food in the genus Oryza. It is an annual gramineous plant with monocotyledons and a temperature-loving climate. Wet, about one meter when mature, with slender leaves. Rice can be divided into indica rice and hard rice, early rice and late rice, glutinous rice and non-glutinous rice according to the rice type. The rice fruit is rice, which is called rice after removing the outer shell. It is one of the world's major food crops.

2. Different shapes

(1) The wheat stalks are upright and clustered, the leaves are flat, long-lanceolate, the apex is tapered, and the base is square-round. The spikes are upright and are called "wheat ears". The fruits are oblate or oval and light brown in color. The ends of the fruits are slightly pointed or rounded. The powder of the fruits is white. The stems and leaves of the plant are shriveled. Seeds, seed coats, etc. can all be used for medicine.

(2) The rice stalks are upright, and the leaves are alternate in two rows and are linear-lanceolate. Rice belongs to the fibrous root system. The panicle is a cone-shaped inflorescence, which is relatively loose, self-pollinated, has many branches, and has rough edges. It hangs downward during maturity. The spikelet is oblong in shape, with both sides flattened. It contains small flowers and is cone-like. Has short awns.

3. Different environments

(1) Wheat requires well-structured and deep soil to survive, which is conducive to water and fertilizer storage and promotes root development. Wheat is a long-day crop. If the light conditions are insufficient, it will not pass the light stage and will not bear fruit.

(2) Rice likes high temperature, humidity and short light environment, and does not have high requirements on soil.

2. The growth process of rice

1. Seedling stage: This stage is the stage when seeds germinate and organic matter accumulates in the plant, providing a material basis for growth and development.

2. Tillering stage: During this period, the tillering speed is slow, the growth becomes increasingly vigorous, the number of tillering increases sharply, and the fastest period of tillering is the peak tillering stage.

3. Jointing stage: This stage is the stage when the plant forms product organs.

4. Flowering stage: At this stage, tillering has stopped, so attention should be paid to the use of ear fertilizer.
