What is the annual output of asparagus after four years?

The annual output of asparagus in four years is 4000-5000 Jin. Under conventional planting, the yield of asparagus planted for 4 years is about 4000-5000 kg per mu, and the dry goods are about 400-500 kg.

Due to different sowing time, methods and management methods, the yield will be different. Asparagus is a perennial herb of Liliaceae, which is distributed in central and southern China, East China, Henan, Hebei, Shanxi, Shaanxi, Sichuan, Gansu, Taiwan Province and Guizhou provinces.

Planting method of asparagus

First, soil, because asparagus belongs to root plants, so we must pay attention to choose soil with good ventilation and drainage, otherwise if there is water in the soil, its roots will rot easily. Humus soil can be used with gardening soil and then river sand can be added, which can drain excess water from the soil well.

Second, propagation, asparagus can be propagated by ramets. Generally, a vigorous asparagus can be divided into three trees. After the wound is dried, it can be planted in the soil to keep the soil moist and maintained in the shade for half a month.

Third, change the pot because its roots grow faster, so pay attention to choosing a slightly larger flowerpot. The pot has to be changed every year. When changing pots, the old roots should be trimmed properly and the new soil should be replaced. When the asparagus in the flowerpot is full, it needs to be divided into pots, and the time can be chosen in autumn and September.

Fourth, water and fertilizer, when watering asparagus, we must be careful not to let water accumulate in the soil. Water once every three days in spring and autumn, and it is hotter in summer. Water it once a day and put it in a ventilated place after watering. Because it is an evergreen plant, we should pay attention to fertilization to make it grow better. We can use diluted compound fertilizer once a month.
