Introduction to the key techniques of efficient cultivation and management of asparagus

Water spinach, also known as water spinach, water spinach, etc., is one of the favorite vegetables in people's life, because of its white trumpet flowers, and the center of the vegetable stem is empty, so it is named "spinach". Asparagus has been planted in many places in our country. Let's take a look at the key points of efficient cultivation and management of asparagus.

1. When do you usually plant asparagus?

Asparagus is usually planted from April to July every year and likes sufficient light, but it also has strong adaptability to close planting and loose requirements on soil conditions, but because it likes fertilizer and water, it is still better for the soil with relatively viscous weight and strong water and fertility conservation. Leaf tips grow a large number and rapidly, requiring large amount of fertilizer, strong fertilizer tolerance and high demand for nitrogen fertilizer.

1. Variety selection

Generally speaking, there are two common varieties for reference, one is bamboo leaf, as the name implies, its leaf shape is very similar to bamboo leaf, this kind of characteristic is heat resistance and waterlogging resistance, and grows faster in summer. There is also a variety of willow leaves, leaves into the shape of willow leaves, dark leaves, summer planting in the south, generally 20 days or so can be harvested.

two。 Planting management

Asparagus has no requirement for soil and can be grown in ordinary soil. To choose a higher terrain, the soil has a certain water content of the soil, is the most appropriate. In the early stage, it is necessary to loosen the soil in time to raise the surface temperature. But in summer, because the temperature is relatively high, asparagus grows fast and the demand for water is higher. It should be watered in time and flooded. If the weather is dry and the soil is dry, the taste of asparagus will be affected. After watering, you need to fertilize it. In autumn, weeding should be carried out in time, fertilizers should be applied, pests should be controlled, and so on.

3. Pest control

The easiest thing to get when growing asparagus is white rust. In order to avoid this disease, the first way is to carry out crop rotation. Before planting, the seeds should be mixed with pesticides. In the onset of the disease, but also spray related pesticides, usually once every seven days.

Specific method: to grow asparagus, be sure to choose healthy seeds and healthy land. Newly bought seeds are usually soaked in warm water of 50 degrees for 30 minutes before they can be planted. There is also management, which should be planted in high-lying, well-drained and well-ventilated places. There is an ample supply of fertilizer and some phosphate and potash fertilizer should be properly applied. There should also be an adequate supply of water, and once it is found that the asparagus has a disease, it should be pulled out in time. In the early stage of the disease, it is necessary to spray pesticides in time, usually once every seven days, and it can be controlled after three times.

4. Harvest and keep seeds in time

In the cultivation of asparagus, we must remember to harvest it in time, usually when it grows to about 20 centimeters. Generally, it can be harvested two or three times, leaving two nodes above the root of the stem.

After the harvest, you can leave the seed. Generally speaking, in May, the seedlings left behind are planted upside down in the earth, with a distance of about one meter and two seedlings in one hole. After the upside-down planting, there is no need to water and fertilizer, but to build a shed. Lead the main stem to the top of the shed, and then lead the side branches to the upper shed. If you keep the seed, you should pay attention to insect pests. It usually blossoms in August, and the seed will mature in October.
