Introduction of soilless cultivation technology and time of asparagus!

Asparagus is a common vegetable in China, which likes to grow in warm and humid areas and is more common in the south. It is also widely cultivated in various provinces and cities in the Yangtze River basin. What is the soilless cultivation technique and time of asparagus? The following will be answered slowly by the editor of Tuliu.com.

I. the basic situation of asparagus

1. The origin and alias of asparagus

Asparagus is an annual herb, also known as puccinellia oleifera, Ipomoea angustifolia, rattan vegetable, Tongcai and so on. It is commonly cultivated in the central and southern provinces of China, but it is relatively rare in the north. It is suitable to grow in places with warm and humid climate and fertile and humid soil. In addition, it is also partially distributed in tropical Asia, Africa, Oceania and other places.

two。 The value of asparagus

Hollow cabbage is rich in crude cellulose, vitamins and other nutrients, which can promote gastrointestinal peristalsis, laxation and detoxification, and it is a kind of alkaline food, which can reduce intestinal acidity and prevent intestinal flora imbalance. It is helpful to prevent cancer to a certain extent, and the effect of lowering cholesterol and triglyceride is more obvious. In addition to the efficacy of eating, the stems and leaves of asparagus can also be used as medicine, which has a certain auxiliary effect for the treatment of constipation, turbid, hematochezia, blood in urine, hemorrhoids, carbuncle, broken wounds, snakebite and so on.

2. cultivation time and soilless cultivation techniques of asparagus

In addition to the common soil cultivation, the current soilless cultivation technology is also very good, so here is a detailed introduction for you.

(1) cultivation time of asparagus

1. At present, there are two kinds of cultivation of asparagus in open field and greenhouse, so the planting time will be different. Generally sowing asparagus in the open field can be carried out in April-July of each year; if it is planted in greenhouse, it can be carried out in October-December.

two。 In addition, the planting time of asparagus is also different in different regions, such as Guangzhou from December to February, the middle and lower reaches of the Yangtze River from April to October, the northern region from April to July, and Shenyang can sow seeds in mid-April. Of course, the climate change is different from year to year, so we can adjust it according to the situation when planting.

(2) soilless cultivation techniques of asparagus

Because water spinach is a kind of amphibious plant, it can also be cultivated in soilless culture in addition to common soil cultivation, while water spinach (also known as leafy species or water spinach) is commonly used in soilless cultivation. The detailed soilless cultivation techniques are as follows:

1. The cultivation method of using substrates other than natural soil to provide water, nutrients and oxygen to crops is usually called soilless cultivation. Therefore, the cultivation of asparagus should first prepare the nutrient solution for cultivation and establish a suitable cultivation trough, and the size of the cultivation trough should be determined according to the situation in the field.

two。 Prepare the seedling substrate, sub-install the seedling substrate into the hole plate, compact the substrate soil and water thoroughly after sowing, keep the substrate moist before emergence, water after emergence, and supplement biogas liquid nutrient liquid; seedlings are ready to transplant after growing 3-4 true leaves.

3. Prepare the floating board, fill the cultivation trough with biogas liquid, then select the seedlings and fix the seedlings in the floating board planting hole.

4. If floating cultivation is used, biogas slurry nutrient liquid is generally added at one time or periodically, and water is replenished every 2-3 days.

5. Because the use of nutrient solution to cultivate asparagus, once diseases and insect pests occur, it is very easy to spread through the flow of nutrient solution, so in the process of cultivation, attention must be paid to the invasion of diseases and insect pests such as anthracnose, corruption, green insects and so on. Once found, it should be dealt with in time.

The method of soilless cultivation of asparagus is still relatively simple, generally can be carried out at home, interested friends might as well try to plant some of their own.
