The latest fertilization method of Atractylodes macrocephala Koidz
Atractylodes macrocephala Koidz is a perennial herb whose main economic value is rhizome and generally grows in the south of the Yangtze River. It has high medicinal value and has been in great demand in the market at present. There are a large number of artificial cultivation, but in order to obtain high yield, high yield and high quality rhizome, fertilization is needed to help the growth. If there is any need for fertilizer in Atractylodes macrocephala Koidz, how to apply it, what to do there, and how much to apply, read the following questions with such questions to find the answer.
I. Fertilizer demand
Atractylodes macrocephala Koidz mainly depends on expanding roots to stabilize its plants, and beard roots to absorb water, nutrients, and other organic matter. Therefore, the root absorptive capacity is not strong, inflated roots need to be protected, only a small amount of multiple fertilization, fertilization can not apply high concentration fertilizer, do not apply high calorific fertilizer. Fertilizer retting can reduce some heat, and sterilize, easy to absorb. The root of the root is not wide, the depth is less than 20 cm, fertilization should not be spread throughout the garden, concentration is conducive to absorption.
II. Fertilization methods
Centralized fertilization is more conducive to root absorption and utilization, can be in the middle of the planting row to open a depth of 10 cm wide 10 cm to apply, so that it is not far from the root, will not hurt the root and can be well absorbed. Or the method of annular ditch application is used, that is, each plant's root system is 10 cm away from the root to dig an annular ditch to fertilize, the ditch depth is about 10 cm, so that fertilization absorption is the most comprehensive and not wasteful.
III. Fertilization
1. Base fertilizer
First of all, select the land before planting, if the selected place is relatively barren, then you need to apply fertilizer to improve the soil, and apply it together with base fertilizer to increase some usage. About 1500 jin of farm manure is applied per mu, and if the land is more fertile, then some amount can be reduced, about 1000 jin per mu. When the soil is turned deep, it is time to bury it in the soil. Rotary ploughing and breaking the soil is beneficial to mix together and make it fully uniform.
two。 Slow seedling fertilizer
After the first topdressing is planted in the seedlings and after the slow seedling stage, it is necessary to water and fertilize once in time, and no fertilizer can be applied during the slow seedling period. This time it is mainly watering, providing water for the plant to stand upright to transport light and action products. But fertilizers should be added to promote the growth of leaves and roots to produce more nutritional products and speed up growth.
3. Flowering and strong root fertilizer
After flowering, the main thing is to turn to the reproductive growth of the underground rhizome, and topdressing is needed for the growth of the rhizome in the later stage. Flowering needs to consume a lot of nutrients, generally mainly to apply more phosphorus fertilizer, to meet flower growth, less nitrogen fertilizer, to avoid excessive growth on the ground. When it comes to the main growth period of the rhizome, we need to apply more potash fertilizer to strengthen the rhizome, and the use of nitrogen fertilizer can satisfy photosynthesis.
4. Postharvest fertilizer
Atractylodes macrocephala Koidz is a perennial plant, so after the rhizome is harvested, the plant will still grow and continue to grow roots in the coming year. Therefore, farm manure must be applied within a week after harvest, which can actually be counted as part of the base fertilizer for the second year. These fertilizers are also required to keep growing normally in winter. About 500 jin per mu of fertilizer.
Atractylodes macrocephala Koidz needs a good continuous supply of fertilizer in order to maintain good growth without external influence, so we should pay attention to fertilization, targeted fertilization, not lack of fertilizer, which has a certain guarantee for yield and quality.
