Planting method and time of asparagus

Asparagus is mainly distributed in the south, but it is rarely planted in the north due to climate reasons. It is rich in nutrition and has the effect of cooling blood and detoxification, so it is a more popular vegetable. The following pro-agricultural network brings you detailed methods and time for planting asparagus. Let's have a look.

Planting time

Asparagus is a sunny, hot and humid environment, seed germination requires a temperature of more than 15 degrees, so it is generally planted in April-July, while in the north, the temperature is relatively low, generally planted in June-August.

Planting method

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 in the greenhouse to accelerate germination, rinse them once a day until a large area begins to whiten, and then 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, except when it is planted with sufficient base fertilizer, but when it grows to 5cm, it needs to be watered and fertilized to make it grow rapidly, and the soil should be watered frequently in the future 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.

The above are the planting methods and time of hollow vegetables brought by pro-agricultural network, and the vegetables can be harvested repeatedly in the hollow vegetable market, but we should pay attention to leaving enough 2-3 nodes at the base of the stem when harvesting, so as to facilitate the germination of new buds after harvest, so as to promote high yield.
