Fishy prairie is a wild vegetable grown in many places in the south, because it is loved by many people, some people began to seize the business opportunity to grow houttuynia cordata. Planting houttuynia cordata, like other vegetables, requires appropriate and meticulous management during the growing period, especially the growth is mainly promoted by fertilizer nutrition, so it is necessary to learn how to fertilize and when fertilization will have a better effect.

First, fertilizer requirements

Because it is mainly harvested its rhizome, and its rhizome is deep and widely distributed, and most of the plants will grow together, so fertilization should be comprehensive, and the fertilization site should reach the depth that all rhizomes can absorb. And should apply more potash fertilizer, less nitrogen fertilizer and phosphorus fertilizer. It takes a long time to take root, and it is best to apply farm manure. The amount of fertilizer should be sufficient.

II. Fertilization methods

In general, base fertilizer can be applied in the whole field combined with ploughing mixed soil, so a wide range of fertilization 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, without covering the soil, to avoid damage to the root system or root aging. In addition, combined with weeding, ploughing and fertilization, you need to mix the soil, you can no longer cover the soil. And in the prosperous period, potassium dihydrogen phosphate is sprayed on the leaves.

III. Fertilization

1. Base fertilizer

Before sowing, it should be applied during soil preparation, and after application, rotary tillage should be mixed and meticulous. Base fertilizer application of farm animal manure, leaf straw compost, do not apply poultry manure, high concentration, root damage. Generally, the application amount per mu is 2000 jin of farm manure, which is used evenly, and watering once a week after the application of base fertilizer is beneficial to absorption.

two。 Topdressing

The first time is to grow two leaves after emergence when the plant height is 5 to 10 centimeters. The main application of nitrogen fertilizer, such as urea, can generally be applied in a trench between the planting rows. Urea nitrogen fertilizer has high fertilizer efficiency, generally applying about 25 jin per mu, which can mainly promote the growth of seedlings. The second topdressing is used before and after the Qingming Festival, when the rhizome grows most vigorously. At this time, the rhizome will grow rapidly, so it is necessary to apply farm fertilizer and a small amount of phosphate fertilizer at this time, and apply a small amount of potassium dihydrogen phosphate outside the root. In the later stage, we can observe whether there will be fertilizer deficiency, if the lack of fertilizer can be applied many times, and Houttuynia cordata like fertilizer, many times topdressing, can make the root system stout, white and tender. However, fertilizer should be stopped one month before harvest to avoid waste.

If vegetables want to grow well, they all need fertilizer to protect them, and so is the planting of Houttuynia cordata Thunb. It likes to be fat and needs a lot of fertilizer. If it can meet its demand for fertilizer, the growth quality and yield of Houttuynia cordata Thunb will be more than half guaranteed.
