How do you grow upland rice? What breed to say?

Upland rice seeds upland rice 297, upland rice 906, green drought 1, Zhenghan 9, Linhan 1, Qinai varieties are good.

1. Upland rice 297. It is a japonica-shaped conventional upland rice variety with a growth period of about 136 days. This variety has good yield, excellent rice quality, rice blast resistance, and strong drought resistance. It is suitable for dryland planting in the central and southern parts of Liaoning Province, the central and northern parts of Hebei Province, Beijing and Tianjin.

2. Upland rice 906. It is an indica-type conventional upland rice variety with a full growth period. The plant type is relatively compact, and the effective spike per mu is resistant to sheath blight and medium resistance to black streak dwarf shrinkage. The average yield per mu was higher than that of the control Fengliangyou.

3. Green Drought No. 1. It is an indica-type conventional upland rice, with moderate maturity, high yield, moderate susceptibility to rice blast, and weak drought resistance. It is suitable for one-season upland rice planting in some hilly areas with light rice blast and light drought in Zhejiang, Jiangsu, Hubei, Anhui, Jiangxi and Fujian.

4. Zheng Han No. 9. It belongs to japonica conventional early rice, with high yield, strong drought resistance, medium resistance to rice blast, and average rice quality. It is suitable for summer-sown early rice planting in the rice areas of the Huanghuai River Basin in Henan Province, Jiangsu Province, Anhui Province and Shandong Province.

5. Linhan No. 1. It belongs to japonica conventional upland rice. This variety has good yield, stable yield, strong lodging resistance, medium drought resistance, medium susceptibility to rice blast, and excellent rice quality. It is suitable for summer-sown upland rice planting in the Huanghuai River Basin of Henan Province, Jiangsu Province, Anhui Province and Shandong Province.

6, Qin Ai. Japonica conventional upland rice has a large panicle, broad-grained ovate, large grain, developed root system and strong drought resistance. Qinai is a variety with weak photosensitivity and weak temperature sensitivity, which can be interlaced with corn to increase the yield per unit area.

Moreover, the growth period is short, the harvest period is early, and it is published in wheat to sow early in time to catch strong seedlings.

What is the difference between upland rice and rice

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 dry land, slope land and arid ecological environment, and is a variant of rice.

Upland rice, also known as upland rice, is similar to rice in terms of biological characteristics, external morphology and internal anatomy, and it can be considered that upland rice is an evolution of 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 also relatively low compared to rice.

Dry rice farming can make full use of natural precipitation, so that rice planting is no longer limited by artificial irrigation, so that the rice planting area can be greatly expanded, and rice yield can be increased.

1. Find a suitable sowing area.

Since upland rice is a semi-arid and half-water plant, it is most suitable for planting in areas where water is scarce, commonly known as the harvest of the sky, and in low-lying areas where other dry crops are susceptible to waterlogging. Upland rice and wheat planting are the same as dry sowing, and as long as the soil has moisture throughout the growing season, there is no need to circle water in the field for maintenance.

2. Soil preparation and fertilization.

Land preparation requires refinement, deep ploughing, harrowing, flattening and other work, deep ploughing depth of about 20cm, pay attention to removing large soil clods in the field. Fertilization should be applied to the bottom of the plant, and the conditions for applying farmhouse fertilizer can make the combination of farmhouse fertilizer and chemical fertilizer, rice is relatively sensitive to nitrogen, and the amount of phosphate fertilizer and potassium fertilizer should not be too small.

3. Sow seeds at the right time.

In the middle and lower reaches, early rice is generally sown in late March and early April. Before sowing, the rice seeds should be left to dry in the sun for three or four hours, and the sun's ultraviolet rays can kill some germs and viruses on the seed husks. There are two types of sowing in drylands:

One is manual sowing, and the other is machine stripping. The sown upland rice is relatively uniform, but the amount of seeds is slightly more, the bottom fertilizer should also be sprinkled, and the fertilizer utilization rate of strip sowing is higher.

4. Reasonable irrigation.

Although it is upland rice, it is also necessary to carry out reasonable irrigation to ensure the water absorption of upland rice during the growth process, but do not flood irrigation, and irrigate when there is drought in the field.

5. Top dressing and weeding.

When the seedlings of upland rice grow to about 20 days, they officially enter the tillering stage. In order to make it have enough nutrients and more tillers, it is necessary to apply fertilizer once, which can be about 18 20 catties of urea per mu.

6. Pest control.

Common pests and diseases are rice blast and borer. Rice blast control: spray evenly with 40% rice blast wettable powder 400 times liquid + 2% spring budmycin water solution 500 times.
