Alpine Dutch bean back-season cultivation

The Dutch bean season was cultivated for winter sowing and harvesting in spring, so after the end of June, there were very few Dutch beans available on the market. Utilizing the cold summer climate to cultivate Dutch beans, the output value per mu can reach about 2,500 to 3,500 yuan. The anti-season cultivation of the Dutch beans is not exactly the same as the seasonal cultivation. Attention should be paid to the following aspects.

Choosing a suitable altitude The Dutch bean is a low-temperature type crop that is not tolerant to high temperatures. In the case of high temperatures, especially viral diseases, the yield is low, and the quality is poor. Some even do not produce Dutch beans. To choose a place where the summer is not hot. According to the law that the temperature drops by 0.6°C every 100 meters above sea level, it is better to plant in high mountains, and it is generally preferable to plant at 600-800 meters above sea level.

Select the appropriate varieties of semi-fascicular species can choose Japanese summer wolfberry peas, second female No. 2, the species can choose to use Taichung on the 11th, Japan's Songdo No. 30. These varieties are disease resistant, strong branching, and heat-resistant.

The timely application of boron fertilizer, molybdenum fertilizer, every 8 to 10 days spray 1 green Fenwei 1 or spray Shibao have significant yield increase effect; for the creeping species, when the seedling height of 20 cm or so, pay attention to promptly insert the rod stand ;Pest Control. Root rot can be seeded with carbendazim and Jinggangmycin before sowing, and the application of the drug after 5 to 6 days of spraying in Dutch beans can control brown spot and powdery mildew.
