Summary. Expand knowledge: 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 the rice bran layer.

Nearly half of the world's population relies on rice as a staple food. In addition to being edible, rice can also be used as industrial raw materials for brewing and sugar making, and rice husks and rice stalks can be used as livestock feed. The main rice producing areas in China are mainly the Yangtze River Basin, the Pearl River Basin and Northeast China.

Rice is a direct cash crop, rice is the staple food of Chinese residents, the current domestic rice planting area is 100 million mu of conventional rice, and the planting area of hybrid rice is 200 million mu. A group of Chinese scientists has made a rare contribution to rice scientific research in the world: Academician Yuan Longping is known as:"The father of hybrid rice"Academician Zhu Yingying has made outstanding contributions to the research of hybrid rice, and farmer Hu Daishu has invented regenerative rice in the past few years.

Hello, dear, I am glad to answer for you, after the official inquiry, the introduction of the 1718 rice variety in the adaptation area from seedling to maturity is about 135 days, and it takes 10 active accumulated temperatures of about 2480-2550. The main stem and leaves of this variety, long-grained type, the plant height is about 98 cm, the spike length is about 22 cm, the hall contains the number of grains per spike is about 140 grains, and the weight of 1000 grains is about 27 grams.

The Chinese scientific Liang Lijia group has made a rare contribution to the scientific research of water rubber rice: Academician Yuan Longping is known as"The father of hybrid rice"Academician Zhu Yingying has made outstanding contributions to the research of hybrid rice, and farmer Hu Daishu has invented regenerative rice in the past few years.

Appearance characteristics: Longjing 3040 rice leaves are round-grained, and the plant height is about 93 cm. Yield characteristics:

In the 2019 production experiment, the average yield per hectare was kilograms. Fertilization characteristics: the method of segmented fertilization is adopted.

Special features of weeding: weeding is carried out in two ways: closed before and after cutting, or stem and leaf treatment in the later stage.

1. Appearance characteristics

Longjing 3040 rice belongs to grape japonica rice.

The whole growth period is about 127 days, the leaves are round grained, the plant height is about 93 cm, the spike length is about 15 cm, the number of grains per mu is 104, and the dry grain weight is grams, which is suitable for sowing from April 15 to April 25.

2. Yield characteristics

In the regional experiment of Longjing 3040 rice in 2017-2018, the average yield per hectare was kg, which increased compared with Longjing 46 rice, and in the production experiment in 2019, the average yield per hectare was kg, compared with Longjing 46, the yield increased.

3. Fertilization characteristics

Longjing 3040 rice can be fertilized in stages, and the base fertilizer, green fertilizer, tillering fertilizer and ear fertilizer can be applied reasonably and segmented during the plant growth period, so that it can have sufficient fertilizer during several growth periods with large fertilizer needs, and promote the healthy growth of rice.

4. Weeding characteristics

Longjing 3040 rice can be weeded in two ways: before and after transplanting, closed or late stem and leaf treatment, in which the stem and leaf treatment method should pay attention to not make the state tan used in the booting stage and flowering stage, the seedlings at this time are more sensitive, and a large number of empty grains may occur when the pesticide is applied.
