Detailed Explanation of Key Field Management Techniques for Hyacinth Beans
The hyacinth bean is a perennial twining vine that is cultivated to some extent in tropical regions around the world. Its pods, flowers and other parts are all edible, and it offers various benefits such as strengthening the spleen, stopping diarrhea and reducing tumors. It is a vegetable with relatively high economic value, so how should we manage it when growing hyacinth beans? Below, the editor brings you the key field management points for hyacinth beans. Let's take a look!
1. Plant training
Because the hyacinth bean is a vine, we need to do a good job of trellising after the plants have established. Guide the vines onto the stakes, and set up the trellis with reasonable distribution according to the planting row and plant spacing of the hyacinth beans. Secure the tops of the stakes well to prevent them from being blown over by wind, then connect the tops of nearby adjacent stakes with wire. This makes it easier for the hyacinth beans to climb and grow, satisfying their hedge-type growth habit. After the hyacinth beans enter the growing period, pay attention to controlling the number of leaves on the plants. Promptly thin out overly dense leaves, old and weak leaves, and poor-quality leaves affected by pests and diseases. This avoids excessive nutrient consumption, improves air circulation within the plants, and promotes the growth of the hyacinth bean pods.
2. Temperature management
Hyacinth beans have certain temperature requirements during growth. When growing hyacinth beans, we should adjust the temperature reasonably according to their growth stage and condition. For example, during the flowering and pod-setting stage, the temperature should be controlled at 17-26 degrees, with around 20 degrees being the optimal temperature. Temperatures that are too high or too low will have a great impact on the flowering and pod setting of hyacinth beans. When the temperature is above 31 degrees, it will worsen flower and pod drop in hyacinth beans and reduce quality. Therefore, when the temperature is too high, ventilation and cooling must be carried out in time; conversely, when it is too low, good insulation work should be done.
3. Fertilizer and water management
About 3 weeks after transplanting and establishing the hyacinth beans, apply a suitable topdressing of nitrogen fertilizer and compound fertilizer once to promote the growth of the seedlings. Then, during the flowering and pod stage of the hyacinth beans, control the amount of water and fertilizer, and it is best not to apply irrigation. Wait until the first inflorescence has set pods before starting water and fertilizer work. If there is plastic film mulching, then when watering it is best to water under the film, together with well-rotted farmyard manure. When applying nitrogen fertilizer, pay attention to the use of ammonium nitrogen; excessive use of ammonium nitrogen will hinder the growth of hyacinth beans. Therefore, when topdressing nitrogen fertilizer, it is best to mainly use nitrate nitrogen, and control the amount well to avoid fertilizer damage.
4. Pest and disease control
Pests and diseases can have a great impact on the yield and quality of hyacinth beans. When growing hyacinth beans, we must pay attention to pest and disease control work. Common pests and diseases of hyacinth beans include viral diseases, rust, and the small gray butterfly, among others. They all harm different parts of the hyacinth bean to varying degrees, hindering its growth. So we should try to understand the common pests and diseases of hyacinth beans well and master the symptoms of onset, so that after onset we can promptly identify the specific condition and then carry out corresponding control work. Do not use pesticides blindly, to prevent pesticide damage that would instead affect the growth of the hyacinth beans.
The above is a brief introduction to the field management of hyacinth beans. The management work for hyacinth beans is very important. When growing them, whether management is good or bad directly determines the yield and quality of the hyacinth beans, so everyone must pay close attention! That is all for today's introduction.
