Introduction to the latest course of asparagus planting techniques and methods

Asparagus is a kind of herb belonging to Liliaceae and Asparagus, which is widely distributed in China. At present, there are still some wild resources in Xinjiang, but most of them are cultivated artificially in other areas. Asparagus is not only a vegetable, but also a medicinal material. When it is used as a vegetable, it is mainly in the tender seedling stage. Do you know how to grow asparagus? What kind of process is asparagus planting? Today we will learn the planting techniques of asparagus together.

1. Soil and fertilizer management

Asparagus has strong resistance and is generally easy to plant. The survival rate of cultivation can basically reach more than 95%. Asparagus has a good adaptability to the environment, and general planting land can be used to grow asparagus. However, if you want asparagus to grow well, yield well and quality well, then the soil should be fertile, rich in organic matter, rich in water resources, pollution-free, deep in soil layer, good in permeability, strong in water and fertilizer conservation and sufficient in light. Note that previous crops should not be lily plants, and do not plant in sticky fields. Before soil preparation, we should sprinkle enough farm manure, the dosage should be controlled at about 1,000 kg, and the soil preparation should be carried out with about 20 kg compound fertilizer. We should deeply plow, make the soil fine, and then furrow and make the ridge flat.

2. Breeding methods

We should choose good asparagus seeds, and at the same time, we should soak seeds and germinate. Because the hardness of asparagus seeds is relatively large, water absorption capacity is poor, so we have to put the seeds into the warm water temperature of about 30 degrees for two days, in the process of soaking, generally change the water once a day, and wash once a day with clean water to avoid rotten seeds. Asparagus seeds in the process of germination, if there are about 10% of the seeds exposed bud white, we can carry out sowing, which is also a difference between it and other crops germination. Sowing is generally the use of direct seeding and drilling methods, the seeds will be evenly scattered in the field, and then cover the soil, watering again, waiting for the seeds to emerge.

3. Cultivation techniques

After the asparagus seeds emerge, when the seedlings grow to about 15 cm, we can carry out thinning and transplanting, and the density should be controlled at a row spacing of 40 cm and a plant spacing of about 25 cm. After planting survival, it needs to cover soil twice, which is about half a month after planting survival and about one month after planting survival. When the earth is covered, the weeds that grow in the field should be cleaned up. When the seedlings grow to about 12 cm, the first topdressing is carried out, mainly based on cake fertilizer. Later topdressing needs to be carried out according to the growth of asparagus, but the last fertilization is before the annual frost, which can improve the resistance of asparagus, so that it can safely winter. There is also that we in the process of topdressing, or to apply more organic fertilizer, as little as possible with chemical fertilizer. Finally, we need to keep the soil moist. In the hot and dry season, we should water it in time, while in the cold or whitebait weather, we need less watering and timely drainage.

4. Disease and pest control

The main diseases of asparagus are anthracnose, brown spot and rust. These three diseases are the most harmful in the growth process of asparagus. Therefore, after the diseased plants, they should be burned in time and the soil should be disinfected. Before and at the beginning of the disease, we can use anthrax, benomyl and fuxing emulsifiable concentrates to control it, spraying once a week, usually two to three times. The most common pests are aphids, red spiders and grubs. When pests are found, they should be killed in time, or low-toxicity insecticides should be used to kill insects.

Asparagus planting is actually very simple, we generally as long as according to the above planting process for planting, basically no big problem. Of course, there are also some details of management technology to understand, if you are interested, you can pay attention to us oh.
