Analysis of the reasons why lotus roots do not grow vigorously after planting

Lotus root growing vigorously refers to the sprouting of the lotus root, the elongation of the lotus root and the extension of the lotus leaves. At the same period, after planting lotus roots, there will be differences in the speed of growing vigorously, and some varieties grow vigorously half a month slower or even longer after planting. So what causes this phenomenon? Let's find out together.

1. Quality of seed lotus roots

The quality of seed lotus roots is the fundamental factor affecting the sprouting of seed lotus roots, the elongation of runners and the growth of lotus leaves. Lotus root is a vegetatively propagated crop, so the seed lotus root is essentially the stem in that sense, and planting a seed lotus root is actually using it as a cutting for propagation. The quality standards for seed lotus roots are: varietal purity of foundation seed must not be lower than 97%, and for field production not lower than 93%; germination rate not lower than 90%; the number of terminal buds on a single seed lotus root segment must be greater than 1, and the number of internodes greater than 2-3. In order to improve the germination rate of lotus roots and promote their early vigorous growth, the basic requirements for the quality of seed lotus roots are complete and intact structure, no injury and no disease, freshness, and appropriately carrying more mud.

2. Cold damage

Cold damage mainly harms lotus roots from harvest to planting, as well as during the initial period after planting. Lotus root harvesting and pre-planting generally occur in March-April, when the seed lotus roots are already in a sprouting state, and the sprouting speed is relatively fast, so they are more sensitive to the environment. March-April is also a period when temperatures fluctuate greatly. During this period, once factors such as low temperature and rainfall occur, cold damage is very likely to happen. When low temperatures are encountered during harvesting, plastic film and straw curtains or rice straw should be covered promptly, or the seed lotus roots should be temporarily stored indoors where they can be sheltered from wind and rain and covered with straw curtains or rice straw. During storage, it is not advisable to water, and measures should be taken to prevent low temperatures at night. After the temperature rises, planting can be carried out, which can reduce or prevent the occurrence of cold damage.

3. Planting time

Different regions have suitable times for lotus root planting. Local growers all have experience, but for novice growers, due to lack of experience, it is easy for them to pursue early planting too much and plant prematurely, resulting in poor sprouting of seed lotus roots and poor early vigorous growth of plants due to low temperatures. Therefore, choosing a suitable planting time is very important. It is recommended to use an average daily maximum temperature greater than 15 degrees and a minimum temperature greater than 5 degrees as reference standards for determining the starting date of field planting for lotus roots.
