How to plant alfalfa grass
Today, the editor will elaborate on how to plant alfalfa grass and share experience in the aspects of green plant maintenance, such as alfalfa grass cultivation techniques and management. Next, the editor will introduce it.
Alfalfa grass is a major feed source for many herbivorous animals, containing abundant crude protein, which greatly helps to improve breeding efficiency. It is now commonly used in pig breeding and is known as the lucky clover. So, how should alfalfa grass be planted? Let's learn about it together!
1. Land preparation
Before sowing, it is necessary to select a suitable planting area. Alfalfa grass is generally planted in loose, fertile, acidic soil. Before planting, pay attention to deeply turn the soil, remove weeds from the field, and apply decomposed organic fertilizer to provide nutrients for the alfalfa grass.
2. Sowing and seedling raising
Alfalfa grass can usually be sown in spring and autumn, and can also be intercropped with other crops, such as oilseed rape and corn. Sow at a certain spacing, cover with fine soil, water sufficiently to ensure uniform and strong seedlings, which is very helpful for the high and stable yield of alfalfa grass in the later stage.
3. Weeding
Removing weeds is to reduce nutrient consumption and facilitate the rapid growth of alfalfa grass. This is usually done during the seedling stage and after the summer harvest. Alfalfa grass is severely affected by weeds at this time, so weeding should be done promptly. Herbicides can be used, but the selection of herbicides should be cautious to avoid harm to livestock caused by pesticide residues on the alfalfa grass.
4. Irrigation and drainage
Alfalfa grass consumes a lot of water and should be watered before winter, after turning green, and during dry spells. Low-lying areas should pay attention to drainage during the rainy season to prevent root rot and death, which would result in the loss of planting value.
5. Disease and pest control
When alfalfa grass encounters diseases and pests during its growth and development, it is necessary to control them in time, otherwise it will affect yield and quality. Generally, insecticides such as fenvalerate, dimethoate, and cypermethrin are used for spray control of pests. If rust, brown spot, or downy mildew occurs, fungicides such as carbendazim and thiophanate-methyl are used for control.
6. Harvesting
Harvesting begins during the flowering stage and should not be started after the peak flowering stage. The number of harvests depends on the growth of the alfalfa grass, usually 3-4 times a year. The timing of harvesting should be controlled to avoid affecting nutrient accumulation.
In summary, this is the introduction to the planting method of alfalfa grass. If you want to plant good alfalfa grass, you must do a good job in field management and reduce the occurrence of diseases and pests.
