Fertilization techniques of Saussurea involucrata

Yacon is also called chrysanthemum potato, because it has a fleshy root like potato. And because the root contains a lot of water and sugar, it is now often eaten as a fruit, which increases its value. There are many problems to pay attention to when planting snow lotus, but fertilization is very important and is the best way to promote results, so briefly introduce its fertilization method.

I. Requirements for fertilizer

The main harvest of snow lotus is fleshy roots, so nutrition is mainly to supply roots, and the other is to maintain the vegetative growth of leaves and stems on the ground. Roots need a lot of water and fertilizer. It needs to grow in deep, fertile, moist soil, and can be applied with a large amount of base fertilizer to improve the soil quality and soil structure. Plastic film mulching and transplanting can be used to prolong the growth period, enhance the photosynthesis and produce nutrients. Yacon is the root to absorb nutrients to supply branches and leaves, leaves and produce nutrients to supply root growth.

II. Fertilization techniques

1. fertilization

It is best to apply mild pig manure, cow dung, or humus soil mixed with fallen leaves, straw and soil. Do not apply poultry manure, heat is too high easy to burn, poor growth.

2. base fertilizer

Base fertilizer is used before planting, while ploughing, general fertilization, and finally mixed soil and then covered with fine soil about 5 cm. Prevent root damage. Its root system is underdeveloped, mainly distributed in 30 cm deep soil, base fertilizer application should be at the bottom of 30 cm, in order to absorb it should put some humus soil on the base fertilizer, which is conducive to absorption.

3. seedling fertilizer

Yacon is planted with bulbous roots, and the growth nutrition before root growth is provided by bulbous roots after planting, but the nutrition of bulbous roots is limited, so it needs to apply some light fertilizer water to promote growth and keep the soil moist. The concentration must be low, otherwise it is easy to hurt the roots.

4. fruit fertilizer

After the seedling stage, the main task is root growth, so topdressing can be applied two to three times throughout the fruit growth period. Every time an interval of one or two months, one mu of fertilizer is about 200 jin. Water and irrigate once a week after each fertilization. is beneficial to fertilizer absorption.

When planting yacon, fertilization should be carried out at different stages of the whole growth period according to its fertilizer requirements. According to the soil conditions, growth conditions to determine the specific implementation of the amount and implementation time. The above content can be used for everyone's reference and understanding, and the comparison is carried out.
