Weeding is to reduce the competitiveness of weeds, prevent Houttuynia cordata from competing for nutrients and water, and affect the growth and development of Houttuynia cordata Thunb. Weeding in the seedling stage is very important, because it is directly related to the growth and yield of Houttuynia cordata Thunb.

2. Water management

Houttuynia cordata Thunb is a kind of crop that likes to be wet and afraid of dryness. In the growth period of Houttuynia cordata Thunb, the soil should be kept moist, and the soil water content should not be less than 75%. Watering in time after sowing or cutting to promote the rooting and sprouting of Houttuynia cordata. Especially in summer and other high-temperature and dry weather, moisture must not be too little. Pay attention to the method of watering, try to use small water drip irrigation to prevent excessive water from causing soil consolidation, which is not conducive to the growth and development of Houttuynia cordata Thunb.

4. Pick the heart and buds

Regular observation of the growth of Houttuynia cordata Thunb, to prevent the growth of Houttuynia cordata Thunb too dense, the emergence of excessive growth and other phenomena. When this situation is found, the branches that are too prosperous and too dense should be removed in time, and then the plant should be done the heart-picking work to inhibit the growth of lateral branches. Let the nutrition concentrate on the rhizome, promote the nutrient accumulation and expansion of the rhizome, and enhance the quality. And if the purpose of planting is not flowers, then they should be removed at the early stage of the bud to reduce the nutritional consumption of flowers and prevent the two growth modes from competing for nutrients.

The above is a brief introduction to the field management methods of Houttuynia cordata Thunb, of which one of the more important is pest control. Pest control is the most important in all management work, Houttuynia cordata Thunb has many different diseases and insect pests, will have varying degrees of impact on Houttuynia cordata Thunb, so as to reduce the yield of Houttuynia cordata Thunb, I hope we must pay attention to it.
