Planting methods and time in yam bean.
The planting time in yam bean is around April in spring, which means that high temperature, warm climate and high soil moisture can increase the probability of yam bean seeds germination. If it is potted, it can be earlier, the time is about March, and the indoor temperature can reach about 20℃.
When planting yam bean, we should choose seeds with bright colors, full terminal buds and thick tubers, and ensure that the tuber length is about 15cm. If the seeds in yam bean are too small, it will lead to poor breathing and difficulty in absorbing water and nutrients.
Germination must be accelerated before planting yam bean. First, yam bean is buried in wet sand and covered with a layer of sand with a thickness of 3-5cm. Then, put yam bean in an environment with a temperature of 25 degrees Celsius and wait for the plants to germinate.
After yam bean germinated, he first dug a ditch in the soil with a hoe, then transplanted it into the prepared soil, keeping the distance between each seed about 15cm, and finally leveled the soil around yam bean with a shovel.
After planting in yam bean, appropriate amount of nitrogen fertilizer should be applied to make the seeds absorb nutrients and promote the growth of branches and leaves. When applying fertilizer, it should be diluted with clear water, so as to avoid the high concentration of fertilizer and burn the roots of yam bean.
Management technology
1. Weeding: During the growth of seedlings in yam bean, there are often many weeds and weeds that seize the nutrients and moisture in the soil and affect the growth of plants. Therefore, in the process of planting and management, it is necessary to weed regularly to keep the soil clean and the growing environment of plants.
2. Loosening: During the growing period, the density in the soil will gradually increase, which will affect the growth and development of plant roots. Therefore, it is necessary to loosen the soil regularly in the management process. You can use manual or mechanical equipment to gently break the lumps and lumps in the soil, so that the roots of plants can grow and absorb nutrients better.
3. Watering: yam bean needs a lot of water in the process of seedling growth, but excessive watering should be stopped in time to avoid affecting the absorption of nutrients by roots and the growth of plants. Usually, the interval of watering and the amount of watering are determined according to the local climate, the nature of the land and the growth state of plants, and need to be flexibly adjusted according to the actual situation.
4. Insect control: During the growth of yam bean seedlings, they are often attacked by many pests, such as aphids, locusts and termites. Therefore, in the process of management, it is necessary to regularly check the growth of plants, find and deal with pests and diseases in time, so as not to adversely affect the yield and quality of seedlings in yam bean.
