It is a common hydroponic vegetable and can also be used as medicine. It has the effect of clearing away heat and diuresis. At present, it has been introduced into China for many years and has rich planting experience. In order to achieve high-yield cultivation techniques, the following points should be done well. Let's take a look at it now.

First, sowing seeds

After sowing and raising seedlings, and then transplanting, the small seeds can raise seedlings in the nutrition plate, wash the nutrition plate, disinfect the culture soil, prevent carrying germs, and sow 2 to 3 seeds in one hole to ensure the emergence rate. Then, the main thing is to water it every day, but to prevent the occurrence of catchment disease and downy mildew, the small arch shed should pay attention to more ventilation and humidity in cloudy and rainy days, and to maintain the temperature needed for germination, but it should be breathable at noon on a sunny day to prevent high temperature burning of seedlings.

II. Planting

In the Yangtze River basin, seeds can be sown in October, and then, planting seedlings, to remove weak seedlings, diseased seedlings, require that the planted seedlings are short and strong seedlings, not slender stems, slender seedlings, and then ask not to plant too deep, affecting the root system growth and absorbing nutrients. Planting roots should cut off most of them to promote the growth of new roots.

III. Management

Loose and breathable sandy loam should be used as planting fields. Then the soil is required to be finely broken, which is conducive to root growth and reduce resistance. Apply 2000 jin of barnyard manure per mu to ensure that the soil is fertile. It is necessary to irrigate the shallow water layer in the field, within 2 centimeters, so that it is suitable for growth, pull out weeds and prevent competition for nutrition. After one harvest, 30 jin of urea can be sprinkled per mu to supplement nutrition.

IV. Harvesting and keeping species

Grow to more than 20 centimeters high can be harvested, harvesting is generally the harvest of tender shoots, or directly all harvested and re-planted. Then the varieties that do not bear seeds can keep the seeds and can only stay over the summer. Cover with shade, cool down and leave seeds. Those who have seeds should pick seeds when they crack in the pods. Dry in the shade.

The specific content of watercress cultivation technology is these, if you have not considered, you can operate according to your own experience.
