High-yield cultivation of broad bean in dryland of high-cold area
Broad bean is an important food crop and economic crop in the alpine mountainous region. Due to its characteristics of strong adaptability, wide use, high yield, etc., it has attracted more and more attention. The main cultivation measures are as follows.
1. Soil conditions Vicia faba should be selected for cultivation on sandy and fertile medium-to-upper plains. The relatively wetland under relatively high temperature should be the best. Before sowing, deep soil preparation should be performed to achieve soil looseness and fineness.
2. Fertilization Vicia faba should be dominated by basal fertilizer, supplemented by topdressing, basal organic fertilizer and superfluous calcium, the general Mushi organic fertilizer 2500-4000 kg, about 40 kg of superphosphate, top dressing with nitrogen fertilizer, Sales of ammonium for trade, generally about 20 kilograms of chasing, and to be applied at the flowering stage.
3. Selection of excellent species generally use horse teeth broad bean, must be strictly screened before sowing, selection of disease-free, full, healthy seeds without injury.
4. Reasonable rotation of broad bean beans should not be disturbed. It must be cropped. General selection of wheat stubble and potato stubble is appropriate. Rotation method is generally: broad bean - yam - ramie or broad bean - flax - yam.
5. Standardization of cultivation and management sowing date is suitable for small to full-grained seedlings. The sowing volume is about 20 kilograms, that is, about 22,000 mu leaves, 2 cultivators, 9-15 cm seedling height, shallow cultivating, and budding before deep cultivating. Cultivate soil, promote later growth, and timely control pests and diseases throughout the growing season. Vicia faba is most prone to red leaves. Appropriate late planting can prevent red leaf disease. Early underground pests should be promptly prevented before sowing.
