Asparagus is a vegetable with high nutritional value, but it is difficult to buy on the market, and it can improve the body's immunity. It is used as a health care product to maintain health. There are so many farmers who grow asparagus now, so many people have begun to learn to grow asparagus. Once they can grow bamboo shoots for many years, then friends who want to grow asparagus, do you know how to grow?

1, thoroughly clearing the garden

Before the beginning of March, the asparagus garden should be cleaned up, including removing the dried stems on the ground, and the rotten leaves on the surface should be cleaned. This will prevent the spread of pests and diseases, reduce the incidence of diseased plants, and conduct a ground spray anti-virus after clearing the garden. Spray 45% of Schnein along the asparagus to kill the germs, or use 50% carbendazim and phoxim insecticide for a fully enclosed spray.

When removing dried stems, it should be noted that each of the asparagus should retain 1-2 asparagus seedlings as the basis for soil and bamboo shoots. The length of the retained shoots is 33cm.

2, watering and fertilizing

Generally, before pouring back to Qingshui in the middle of March, first apply 3000-5000 kg of fully decomposed organic fertilizer on the surface, and then apply the compound fertilizer for ditching, 200 kg per mu, and ditch in the place where the asparagus plants are 30 cm away. The depth of the ditch is 10-15cm, then cover the soil and pour back into the green water.

3, Pei ridge

Green asparagus does not need to be ridged, but it is necessary to cover the bamboo shoots properly. Generally, each plant covers about 15cm of soil, so that the heat preservation and moisturizing promotes early harvesting of asparagus, but planting white asparagus requires cultivating, along the asparagus planting line. The ridge is ridged, the width of the ridge is 60-80cm, the width of the ridge is 30-40cm, and the height of the ridge is 25-30cm. The ridge is generally carried out in the middle of March. The soil of the ridge is required to be dry and wet. If the soil is too dry, it should be watered and fertilized a few days in advance.

4, leaving the mother stem

The asparagus shoots we harvest, its growth mainly depends on the nutrients stored in the root system. The nutrients in the roots of asparagus are not able to meet the needs of collecting bamboo shoots all year round. If excessive shoots are taken, the roots will die and die, so they are harvested. Always keep the mother stem when you shoot the bamboo shoots.

When germination in early spring, each plant selects 3-5 strong asparagus stems as the mother stem, allowing it to grow naturally. When it grows to 1.2-1.5 m high, it tops and promotes the growth of side branches, so that the plants can produce more nutrients to the roots. The bulbs produce more tender stems, which increase yield.

The mother stem is easy to fall in the wind, and a wooden stake is placed along the asparagus planting every other distance. The middle is tied with a wire, and the mother stem is slightly tied to the wire to prevent lodging. Before July, the fruit grows on the mother stem. Remove it in time, so as to avoid the waste of nutrients and promote the robust growth of the mother plant.

5, harvest period management

In the first ten days of March, when a T-shaped or cross-shaped crack appeared on the ridge, it indicated that the tender shoots would be unearthed. Generally, the bamboo shoots began to be harvested in the middle of April. In theory, the bamboo shoots can last until the mid-November part of the ground, but Excessive harvesting of bamboo shoots in actual planting will cause the plant to die of aging, so it is generally harvested for 20-30 days in the first year after planting, 30-40 days in the second year after planting, and so on, with a maximum of 60 days of bamboo shoots per year.

The cultivation of asparagus has its particularity. It is very different from the cultivation of other vegetables. The asparagus on the ground in winter is dead, and the frozen water is poured, so there is no need to manage it. Spring needs to be managed. Mastering these five points, the asparagus grows well and the output is high.
