The cultivation method of water spinach, with planting time

Planting time: from April to July. Treat the seeds: soak them in clean water for 1 day, remove them and wash them, then put them in an environment of 30 ℃ at room temperature to accelerate germination. Prepare hole plates and substrates: choose 72-hole or 123-hole hole plates, and peat and perlite as substrates. Planting: put the seedling substrate in the hole plate, watering and infiltrating into the bottom, you can plant. Planting: line spacing should be controlled in the process of growth. Fertilizer and water management: apply fertilizer once for every harvest.

First, planting time

1. Asparagus is a kind of vegetable that loves light and high temperature, so it is necessary to choose the planting time according to its characteristics. Usually, April to July is the suitable time for planting asparagus. After planting, it can be harvested when it grows to the height of 30cm, and it can be picked once a week.

2. If you want to eat asparagus throughout the season, you need to top fertilize every time you pick it, which is conducive to promoting the growth of its branches and leaves, and you can also remove branches that are too long or too dense when picking. This is conducive to ventilation, uniform light, and the whole harvest period is relatively long, which can be eaten until about October in autumn.

Second, deal with the seeds

There are many varieties of asparagus, generally you can choose varieties with strong disease resistance and good growth, soak the purchased seeds in hot water for about 30 minutes, then soak them in clean water for 1 day, remove them and clean them, and put them in an environment of 30 ℃ at room temperature to accelerate germination. Throughout the budding stage, the seeds should be washed with warm water every day. After waiting for 7 days, the seeds will have white spots, and then they can be planted.

Third, prepare the acupoint plate and matrix

Generally, 72 holes or 123 holes can be selected for seedling cultivation, and peat and perlite are selected for substrates. As long as water retention and air permeability are good, the substrates need to be disinfected and sterilized in advance to avoid pests in the later stage.

IV. Planting

First of all, put the seedling substrate in the hole plate, then scrape off the excess substrate, then pour it thoroughly with water, and wait until the water permeates to the bottom, you can plant it. After the planting is completed, you need to cover it with a film to keep the water. Wait for the emergence of the seedling before opening the covered film, which is conducive to ventilation and light transmission.

5. Colonization

In the process of growing, the row spacing should be controlled, and the seedlings should be watered thoroughly when planting. After the water permeates, the seedlings can be planted in the substrate.

VI. Fertilizer and water management

1. After planting, it is necessary not only to maintain the base fertilizer, but also to harvest topdressing once. Watering depends on the growth. In general, asparagus is fond of moist growth environment, so it is watered about every 5 days.

2. Most people like the delicious and crisp taste of asparagus, especially when it is eaten right out of the pot. In addition to being eaten as a vegetable, it can also be regarded as a kind of feed and a kind of medicine.
