Planting method of asparagus

Asparagus likes viscous and fertile soil, likes high temperature and humidity environment, and is not resistant to frost and cold. Soak the seeds in 50-60 warm water for 15-30 minutes before sowing, put them in a greenhouse to accelerate germination, and sow seeds when a large area begins to whiten. Reasonable close planting should be watered and fertilized when it grows to 5cm to keep the soil moist.

1. Environmental requirements

Asparagus is not strict with the soil, but it likes viscous and fertile soil and likes high temperature and humidity environment. It can withstand temperatures of 35-40 degrees. The optimum growth temperature is 25-30 degrees. It is not resistant to frost, the stems and leaves will die in case of frost, and the temperature below 10 degrees will stop growing; it likes the environment with high air humidity, the environment is too dry, the fiber increases, the stem is thick and old, and the edible sense is reduced.

2. Sowing seeds

The epidermis of asparagus seeds is thick and hard, if directly sown and germinate will be very slow, affecting the planting cycle, and if it is long-term rainy weather, it may lead to seed rot. So soak the seeds in 50-60 warm water for 15-30 minutes before sowing, stir when soaking to avoid scalding the seeds, then soak them in clean water for one day, put them into the greenhouse environment to accelerate germination, rinse once a day for germination, until a large area begins to whiten, you can sow seeds. Can sow or strip sowing, the amount of seed per mu is about 2 kg, after sowing, cover a layer of fine soil, watering to maintain soil moisture.

3. Field management

The growth of asparagus has a great demand for fertilizer and water, so it is necessary to apply sufficient base fertilizer when planting. When it grows to 5cm, it should be watered and fertilized to make it grow rapidly, and after that it should be watered frequently to keep the soil moist. In addition, it is necessary to apply fertilizer in time after harvest, so that it can grow for the second time, and nitrogen fertilizer is the main fertilizer. In addition, although hollow cabbage can be closely planted to a certain extent, it is too close-planted, so that it can not accept light exposure and may rot.
