How to Manage Houttuynia cordata? Detailed Explanation of Key Planting Techniques
Houttuynia cordata is a very traditional Chinese medicinal herb in our country, and many regions now also make Houttuynia cordata 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 market demand is not low either, and now the planting area of Houttuynia cordata is relatively widespread, 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 together!
1. Intertillage and Weeding
After Houttuynia cordata is sown and emerges, the rows should be closed in time to provide a good growing environment for Houttuynia cordata. According to the soil conditions and the growth of the seedlings, carry out intertillage and weeding in time. Intertillage is to improve soil ventilation and air permeability, promote the respiration of Houttuynia cordata roots, and enhance nutrient absorption capacity. 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 directly relate 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 rooting and sprouting of Houttuynia cordata. Especially in summer and other high-temperature and dry weather, water must never be too little. Pay attention to the method when watering, and try to use small-drip irrigation 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. Do not irrigate with seriously polluted or spoiled water, otherwise it will cause various pests and diseases.
3. Timely Topdressing
Before sowing Houttuynia cordata, apply sufficient base fertilizer, because Houttuynia cordata likes fertilizer relatively much. If the base fertilizer is sufficient, then during the growth process 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, appropriate topdressing should be carried out. 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 harvesting Houttuynia cordata, stop topdressing to prevent wasting fertilizer.
4. Pinching and Bud Removal
Observe the growth of Houttuynia cordata regularly to prevent it from growing too densely and showing excessive vegetative growth. When such a situation is found, promptly remove the excessively vigorous and dense branches, then pinch the plants to inhibit the growth of side branches. Let nutrients concentrate in the root and stem parts, promote nutrient accumulation and enlargement in the root and stem parts, and enhance quality. And if the planting purpose is not for flowers, then the flower buds should be removed at the early bud stage to reduce the nutrient consumption of 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 them, another relatively important one is pest and disease control. Pest and disease control is the most important of all management tasks. Houttuynia cordata has many different pests and diseases, all of which can affect Houttuynia cordata to varying degrees, thereby reducing the yield of Houttuynia cordata. I hope everyone will definitely attach importance to it. That is all for today's introduction. This article is for reference only. Thank you all for reading and supporting.
