Alfalfa is a leguminous plant. This kind of plant has thick roots, goes deep into the earth's surface and has strong vitality. For example, apples are mainly chameleon-shaped, with hairless surface, lush foliage and oval seeds. The flowering period is May-July and June-August every year.
Alfalfa is the favorite wild vegetable for people to eat every spring, and it is also the favorite pasture for many animals when they grow up in autumn.
Planting method, soil preparation and sowing of alfalfa 1
When planting alfalfa, soil preparation and sowing is the most important step. Dig deep into the land and apply sufficient fertilizer before planting.
Alfalfa seeds are relatively small and have thin teeth. If the surface soil capacity is particularly poor, the ground must be leveled and carefully cultivated during soil preparation.
When sowing, 7 kilograms of seeds can be prepared per mu. Before sowing, let the seeds dry for 2 to 3 days. When sowing, many different ways can be used, such as drilling, drilling and hole sowing.
2. Tian Tuan management
Field management is very important for planting alfalfa in a large area. If soil hardening is found after sowing and before emergence, the interface should be cleared in time. Only in this way can alfalfa with flowers emerge normally.
After she entered the seedling stage, she was particularly vulnerable to weeds. At this time, it is necessary to carry out intertillage and weed in time.
3. Fertilizer and water supply
When planting alfalfa at ordinary times, topdressing should be done in time during its growth process, especially after turning green in spring and after each mowing, and phosphorus and potassium fertilizers with rich nutrition can be selected.
Alfalfa has a well-developed root system and strong drought resistance, but it also needs more water during the growing period, so it should be watered in time when the weather is dry, but it should be drained in time when there is too much rain, so that there can be no long-term water accumulation in the field.
