The latest fertilization management of Houttuynia cordata Thunb

Houttuynia cordata was originally a wild vegetable grown in many places in the south. Because it was loved by many people, some people began to seize the business opportunity to plant Houttuynia cordata. Planting houttuynia cordata, like planting other vegetables, requires proper and meticulous management during the growth period, especially growth is mainly promoted by fertilizer nutrition, so it is necessary to learn how to fertilize and what period of fertilization can have better results.

I. Requirements for fertilizer

Because it is mainly harvested its rhizomes, and its rhizomes are deeply rooted and widely distributed, and most of the plants will grow together, so the fertilization should be comprehensive, and the fertilization site should reach the depth that all rhizomes can absorb. And more potassium fertilizer, less nitrogen fertilizer and phosphorus fertilizer. Rooting needs fertilizer more fertilizer needs fertilizer for a long time, it is best to apply farm manure. The amount of fertilizer should be sufficient.

II. Fertilization methods

Generally, the basal fertilizer can be applied in the whole field combined with ploughing and mixing soil. This fertilizer application range is wide, which can help the whole field soil to be fertile and conducive to continuous absorption. Topdressing can mostly be applied directly to the surface of the compound quick-acting fertilizer, do not cover the soil is also OK, to avoid damage to the root system or make the root aging. In addition, it is combined with weeding, intertillage and fertilization, which requires mixed soil and can no longer be covered with soil. There is also in the long term, foliar spraying potassium dihydrogen phosphate.

III. Fertilization

1. base fertilizer

Before sowing, apply it when preparing the soil, and after applying it, rotate and mix carefully. Base fertilizer application farm livestock manure, leaves straw compost, do not apply poultry manure, high concentration, damage roots. Generally, the application amount of one mu is 2000 jin farm manure, which is evenly used. After applying base fertilizer, it is necessary to cooperate with watering once a week to facilitate absorption.

2. topdressing

The first time is after the emergence of two leaves when the plant height of 5 to 10 cm, mainly nitrogen fertilizer, such as urea, generally can be used in the planting row furrow. Urea nitrogen fertilizer efficiency is high, generally about 25 jin per mu, which can mainly promote the growth of seedlings. The second topdressing is used before and after Qingming, when the rhizome grows most vigorously. At this time, the rhizomes will grow rapidly, so it is necessary to apply farm manure plus a small amount of phosphorus fertilizer at this time, and apply a small amount of potassium dihydrogen phosphate outside the roots. Later period can observe whether there will be lack of fertilizer, if lack of fertilizer can be applied many times, and Houttuynia fertilizer, many times topdressing, can make the root system thick, white. But stop fertilizing a month before harvest to avoid waste.

If you want vegetables to grow well, you need fertilizer to protect them. The same is true for Houttuynia cordata planting. It likes fertilizer and needs more fertilizer. If it could satisfy its fertilizer requirements, then the growth quality and yield of Houttuynia cordata would be more than half guaranteed.
