The Latest Environmental Requirements for Growing Yardlong Beans
Yardlong beans are also called cowpeas, a vegetable we often eat in our daily lives. The cultivation of yardlong beans also covers a relatively large area in our country, and the market for yardlong beans is growing larger and larger, yet many people still fail at growing them. In fact, growing yardlong beans is not as easy as it seems; yardlong beans have certain requirements for their environment. Below, the editor has put together the environmental conditions yardlong beans need. Let's take a look!
1. Soil
Yardlong beans have fairly strong adaptability and do not demand much from soil fertility, but if you want to grow yardlong beans with high yields and strong quality, then we should still try to choose deep, soft, sandy soil with strong permeability. The previous two crops in the soil should not be crops of the same family and genus, otherwise various pests and diseases are more likely to occur. In fact, the choice of soil for artificial cultivation is quite important to the growth of yardlong beans; although they can grow normally in all kinds of soil, their yield and the quality of the yardlong beans will certainly be affected to some degree.
2. Temperature
Yardlong beans are fairly fond of warmth, and the temperature should be neither too high nor too low; their heat tolerance and cold tolerance are both rather poor. After sowing, the temperature should be kept at around 22 degrees to promote seed germination; outside the range of 8-35 degrees, their germination speed is extremely slow, and they may even fail to germinate. After the seedlings break through the soil, the temperature should be adjusted to around 19 degrees and must not fall below 13 degrees. Then, when they reach the flowering and pod-setting stage, the most suitable growing temperature is around 25 degrees. If the temperature is too high or too low, it is very easy to cause yardlong bean flowers and pods to drop. Also, after sowing, if the accumulated temperature is below 700 degrees, then even if they flower later, they will not set fruit, so in spring you should pay attention to the sowing time.
3. Light
The growth of yardlong beans does not demand much light, and the duration of light will not have too great an effect on their growth. However, this mainly depends on the growth stage of the yardlong beans; during vigorous growth periods such as the flowering and pod-setting stage, yardlong beans do have a certain demand for light. If the light needs of yardlong beans are not met during the vigorous growth period, it can easily lead to various physiological problems such as excessive vegetative growth and flower and pod drop. This has a relatively large impact on the growth of yardlong beans, so when planting we must control light well and create a good growing environment for yardlong beans.
4. Water
Yardlong beans like to grow in a moist environment, but they are not tolerant of waterlogging, though their drought tolerance is not bad. So during the growth period of yardlong beans, the soil should be kept in a moist state; the soil moisture content should be neither too much nor too little, and keeping it at around 65% is sufficient. If there is too little water, the flowering and pod setting of yardlong beans will be affected, delaying the flowering time and reducing the amount and quality of pods. Yardlong bean seeds also need a certain amount of water to germinate, but it must not be excessive; if it is excessive, it can easily cause seed rot and affect the benefits of cultivation.
Therefore, when planting, we must do a good job of watering, both meeting the water needed for the growth of yardlong beans and preventing excessive water from causing waterlogging, root rot, and problems such as pests and diseases, which pose a threat to the growth of yardlong beans.
