Causes and control measures of not growing new roots of wax gourd

Wax gourd is not only eaten as a vegetable, but also can make a lot of candy and snacks, such as the most common is wax gourd sugar, and wax gourd is adaptable, so it is planted in all major areas of our country. In the process of planting wax gourd, it often occurs that new roots do not grow, so many growers worry about white, so what is the reason why wax gourd does not grow new roots? Are there any prevention and control measures? Let's take a look at the pro-farm network.

1. The temperature is too low

Although the wax gourd has a winter name, it is not a vegetable grown in winter. It is actually a temperature-loving and heat-resistant vegetable that grows well at high temperature, while it is easy to freeze and grow poorly in an environment of low temperature and insufficient light. The suitable growth temperature is 25-30 degrees, if the growth temperature is lower than 12 degrees, then its root differentiation will be seriously affected, it is difficult to emerge, do not grow new roots, if kept at low temperature for a long time, it may lead to dead seedlings.

Prevention and control measures: when the temperature is low, it is necessary to raise the temperature, strengthen the duration of light, and promote the differentiation and growth of roots. In case of overcast and rainy weather, artificial heating and supplementary light can be carried out.

2. Improper fertilization

Applying immature fertilizer during fertilization gives off a large amount of heat in the process of fertilizer decomposition, resulting in root burning and seedling burning of seedlings, and the application of large amounts of chemical fertilizer in fertilization will lead to an increase in soil concentration. resulting in a large amount of water loss of wax gourd roots, resulting in no new roots.

Prevention and control measures: when fertilizing, we should pay attention to whether the fertility is completely mature, should not be close to the root system, apply organic fertilizer and farm manure as far as possible, apply less chemical fertilizer, and water in time after fertilization to reduce the concentration.

3. Improper watering

Wax gourd likes humid environment, but avoid waterlogging. If too much water is watered during planting or long-term overcast and rainy weather occurs, the soil will absorb too much water, resulting in heavy soil viscosity, resulting in poor permeability, affecting the respiration of wax gourd roots, hindering the absorption of nutrients by roots, affecting the normal growth of roots, and not growing new roots.

Prevention and control measures: watering a small amount frequently, each watering should not be too much, timely drainage in case of overcast and rainy weather, regular ploughing, loosening soil, and strengthening permeability.

4. Diseases and insect pests

The root nematode disease of wax gourd is also the reason for not growing new roots. after being infested by root nematodes, the root system will bite through the root tissue, secrete saliva and form chemical action in the root tissue, resulting in the formation of nodule-like root knot in the root system, so that the root system can not absorb water and nutrients, affecting normal growth.

Prevention and control measures: disinfect seeds and soil before sowing, remove diseased and residual roots in time, and kill root nematodes with medicament when disease occurs.

The above are the reasons and control measures that the pro-agricultural network brings you that the wax gourd does not grow new roots. After reading it, I hope it can help you, more agricultural knowledge, please pay attention to the pro-agricultural network.
