How to fertilize asparagus

The asparagus here refers to the recognized tender tip of bergamot melon. I hope there will be no misunderstanding. Generally speaking, the cultivation and fertilization of asparagus has its own characteristics, which is different from other vegetables or bergamot planting, and there will be different demand for fertilizer when planting. Therefore, I would like to introduce to you the physiological characteristics of asparagus and the methods of fertilization and high yield.

I. growth characteristics

Asparagus is mainly planted by sowing, mainly in barren mountains and fields. It is generally planted in the open field, but it can also be cultivated in facilities. The main variety is the tender shoot of bergamot melon, the root distribution is not deep, mostly around the root system, generally the main harvest is the tender stem of the plant, and can be harvested all the time during the growth period.

II. Fertilizer requirements

The growth of tender stems needs compound fertilizer with more nitrogen fertilizer, which can not only make the leaves and stems of the plant green and tender, but also ensure the necessary interaction and produce nutrients. Can apply less potash fertilizer, potash fertilizer mainly strong rhizome, apply more potash fertilizer will appear stem hardening phenomenon, can be more in the early stage of planting, less application. Farm manure is the best nutrient of leafy vegetables, which contains a variety of nutrients.

III. Fertilization methods

The seedling base fertilizer is used comprehensively, and the field base fertilizer can only be applied on the ridge. Topdressing is mainly used after the emergence of seedlings to the whole growing period. Topdressing mainly uses strip ditch fertilization, ditching around the ridge surface, and then evenly used in the ditch. Or directly apply fertilizer and water, but may affect the root system and tender stem taste. It's better to do it in a ditch.

IV. Fertilization period

The base fertilizer can be used before sowing or before planting in the field, but after fertilizing and mixing the soil, it is still necessary to cover 2 cm of soil before sowing to avoid damage. Base fertilizer generally applies 1000 jin of farm and livestock manure per mu, or cow manure plus soil pile to make manure. Then there is topdressing, which can always be used in the seedbed and can be fertilized about once a week to promote growth. Once topdressing is used with farm manure and water, urea should be applied in ditches to avoid burns, and topdressing is about 100 jin per mu. Is to set up a frame to plant, constantly harvest and seedling bed to harvest seedlings are the same as topdressing for many times.

Fertilization should be based on the growth characteristics and the main fertilization needs of the harvest site, so that attentive fertilization can achieve twice the result with half the effort. It is most beneficial to the growth of asparagus, and fertilizer can give full play to its role. This is the high-yield fertilization method of asparagus.
