Abstract

The invention relates to the field of crop planting, and particularly relates to a cultivating method of potato seedlings, which comprises the following steps: slicing potato seeds into blocks to obtain seed potato blocks; soaking the seed potato blocks in a rooting solution; then coating the soaked seed potato blocks and sprouting to obtain potato seedlings. According to the cultivating method of potato seedlings, the sliced seed potato blocks are soaked in the rooting solution so that the rooting solution penetrates into the seed potato blocks so as to provide a good base for the subsequent sprouting and rooting; after being coated, the soaked seed potato blocks are sprouted, and the coating treatment is mainly used for prevention of pests and diseases. Finally, the potato seedlings vigorously grow and have emerald green color. After the obtained potato seedlings are sown, the yield is greatly increased, the pests and diseases during planting can be alleviated, and a remarkable effect can be achieved.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a method for cultivating potato seedlings. Background technique [0002] Potato is favored and valued by the world for its characteristics of drought resistance, barren resistance, high yield and high efficiency, wide adaptability, complete and rich nutrients, and long industrial chain. In recent years, China's potato planting area has also been on the rise, reaching 4.887 million hectares in 2005, making it the country with the largest potato planting area in the world, accounting for more than 20% of the world's planting area and about 70% of Asia's. But the national average yield is still lower than the world average, only 14.5 tons / ha. [0003] At present, potatoes mainly have the following problems: first, low yield; second, serious pests and diseases. [0004] In view of this, the present invention is proposed. SUMMARY OF THE INVENTION [0005] The object of the present in...
