How should Houttuynia cordata be managed? A detailed explanation of the latest technical key points

Houttuynia cordata is a very traditional Chinese medicinal herb in our country, and now in many regions it is also made into pickles to eat. However, the taste of Houttuynia cordata is very strange, and many people cannot accept its taste, but there are also very many people who like to eat it. So the market demand is not low either, and the area planted with Houttuynia cordata is now relatively wide, but some people do not know how to manage it after planting. Today, the editor brings you the field management of Houttuynia cordata, let's take a look!

1. Intertillage and weeding

After Houttuynia cordata is sown and emerges, it should be closed in rows in time to provide a good growing environment for Houttuynia cordata. According to the soil condition and the growth of the seedlings, carry out intertillage and weeding in time. Intertillage is to improve the ventilation and air permeability of the soil, promote the respiration of the roots of Houttuynia cordata, and enhance the ability to absorb nutrients. Weeding is to reduce the competitiveness of weeds, prevent them from competing with Houttuynia cordata for nutrients and water, and affect the growth and development of Houttuynia cordata. Intertillage and weeding during the seedling stage are very important, because they are directly related to the later growth and yield of Houttuynia cordata.

2. Water management

Houttuynia cordata is a crop that likes moisture and fears dryness. During its growth period, the soil should be kept in a moist state, and the soil water content must not be lower than 75%. After sowing or cutting, water in time to promote the rooting and sprouting of Houttuynia cordata. Especially in summer and other high-temperature and dry weather, the water must not be too little. Pay attention to the method when watering, and try to use the small-drop drip irrigation method to prevent excessive water from causing soil compaction, which is not conducive to the growth and development of Houttuynia cordata. Pay attention to water quality when watering, and do not irrigate with seriously polluted or deteriorated water, otherwise it will cause various diseases and insect pests.

3. Timely topdressing

Before sowing Houttuynia cordata, apply sufficient base fertilizer, because Houttuynia cordata prefers fertilizer. If the base fertilizer is sufficient, then during the growth of Houttuynia cordata, topdressing can be reduced or even omitted. However, around Qingming Festival is the vigorous growth period of Houttuynia cordata. During this period, in order to ensure that Houttuynia cordata has sufficient nutrients, topdressing should be carried out appropriately. The fertilizer can use decomposed farmyard manure, and the amount should be controlled well, generally at 1500kg/mu. And in order to improve the yield and quality of Houttuynia cordata, foliar fertilizers such as potassium dihydrogen phosphate can be appropriately applied as topdressing. About one month before the harvest of Houttuynia cordata, stop topdressing to prevent wasting fertilizer.

4. Pinching and removing buds

Observe the growth of Houttuynia cordata regularly to prevent it from growing too densely and from showing excessive vegetative growth and vigorous growth. When such a situation is found, promptly remove the branches that are growing too vigorously and too densely, and then do the pinching work on the plants to inhibit the growth of side branches. Let the nutrients concentrate in the rhizome part, promote nutrient accumulation and expansion in the rhizome part, and enhance quality. And if the purpose of planting is not for flowers, then the flower buds should be removed at the early bud stage to reduce the nutrient consumption of the flowers and prevent the two growth modes from coexisting and competing for nutrients.

The above is a brief introduction to the field management methods of Houttuynia cordata, among which another relatively important one is pest and disease control. Pest and disease control is the most important among all management tasks. Houttuynia cordata has many different diseases and insect pests, all of which can affect Houttuynia cordata to varying degrees, thereby reducing the yield of Houttuynia cordata. I hope everyone will attach importance to it. That is all for today's introduction. This article is for reference only. Thank you for reading and supporting.
