Reasons for Lotus Root Planting Failure

The growth of lotus root refers to the germination of lotus root, the elongation of lotus root and the extension of lotus leaves. In the same period, there is a difference in the speed of growth of lotus root after planting, while some varieties grow more slowly or even longer after planting. So what is the reason for this phenomenon? Let's get to know it.

1. Quality of lotus root

The quality of seed lotus root is the basic factor affecting seed lotus root germination, whip elongation and lotus leaf growth. Lotus root is an asexual reproduction crop, so as a kind of lotus root is actually a stem in the sense, planting lotus root is actually used as cuttings. The quality standard of seed lotus root is that the purity of the original species shall not be less than 97%, the field shall not be less than 93%, and the germination rate shall not be less than 90%. It is required that the number of terminal buds of a single lotus root branch is more than 1, and the number of internodes is more than 2-3. In order to improve the germination rate of lotus root and promote its early emergence, the basic requirements for the quality of lotus root are complete and intact structure, no damage, no disease, fresh and proper plenty of mud. no, no, no.

2. Chilling injury

The chilling injury mainly harmed the lotus root from harvest to planting period, and during the initial period of planting, half of the lotus root was from March to April, when the seed lotus root was already in the state of germination, and the germination rate was fast, so it was sensitive to the environment. March to April is also a period of large temperature change, during this period, once the occurrence of low temperature rainfall and other factors, it is very easy to produce chilling damage. When digging at low temperature, cover plastic film and straw curtain or rice straw in time, or temporarily store lotus root in a room that can shelter from wind and rain and cover straw curtain or straw. During storage, it is not suitable to water and prevent low temperature at night. Planting after the temperature rises, chilling injury can be reduced or prevented.

3. Planting period

There are suitable lotus roots in different areas, and the local growers all have experience, but for novice growers, because of lack of experience, it is easy to plant too early and inappropriately early. As a result, the low temperature led to poor germination of lotus root and poor plant growth in the early stage. Therefore, it is very important to select the appropriate planting period, and it is suggested that the average daily maximum temperature is more than 15 degrees and the minimum temperature is more than 5 degrees as the reference standard to determine the initial date of lotus root planting in the field.

The above is the introduction of the reasons why lotus roots are not planted. I hope I can help you. If you want to know more about it, please follow us.
