What are the key cultivation points of the potato-rice-vegetable rotation model?
The potato--rice--vegetable model is mainly promoted in mid- to high-altitude areas. The key cultivation points are as follows: (1) For potatoes, choose late-maturing varieties with high resistance to late blight, such as Jizhangru No. 5. (2) For late rice, it is advisable to choose high-quality combinations such as Liangyou 2186 and D702 Youduoxi No. 1, so as to take advantage of the large day-night temperature difference in autumn in mid- to high-altitude areas and the good grain filling of rice. (3) In mid- to high-altitude areas, winter temperatures are relatively low, so for winter vegetables it is advisable to choose cold-tolerant types and cold-tolerant varieties.
