Problems solved by technology

However, the method of sowing at the end of September will easily cause alfalfa to survive the winter and weeds to grow wildly in the next summer
In addition, because alfalfa seeds are small and the sowing rate is low, adjusting the sowing rate has always been a difficult problem in actual production, which is easy to cause difficult control and uneven sowing.
Alfalfa seedlings are thin and weak, with poor ability to top the soil, resulting in the actual germination rate being lower than the experimental data of germination rate, and deformed seedlings are prone to occur

Embodiment １

[0026] The plot requires a deep soil layer, an appropriate proportion of sand and clay texture, loose soil, ventilation and water permeability, water retention and fertilizer retention, and loam and clay loam are suitable. In addition, it is required to facilitate drainage and irrigation, and the groundwater level should be below 1.5 m. The pH value of the soil is between 6.5 and 8.0, and the soluble salt content is below 0.3%.

[0027] The seeds meet the national seed classification standards, the purity and clarity are not less than 95%, the germination rate is not less than 90%, and the seeds are not allowed to carry quarantine objects.

[0028] Before planting, the plot must be leveled and fined to make the soil particles fine and even, and the porosity suitable. The depth of deep plowing is 25-30 cm. On the basis of plowing, disc harrows and nail-toothed harrows are used to harrow the soil to level the ground.

[0029] Fields with few weeds can be manually removed, and ...

Abstract

The invention discloses a method for sowing alfalfa in spring and summer. The method includes that seeds of the alfalfa and millets are evenly mixed to form seed mixtures to be sown from April to July. The method has the advantages that growth of weeds can be effectively restricted by growth vigor of millet seedlings subjected to mixture sowing; the alfalfa can be favorably fixed in root due to long time span from summer sowing to winter time and water temperature condition is moderate, and the problem of getting through the winter is solved; the innovated method for sowing the alfalfa in spring and summer provides convenience for plant farmers to select sowing periods.

Description

technical field [0001] The invention relates to the technical field of alfalfa planting, in particular to a method for sowing alfalfa in spring and summer. Background technique [0002] Medicago sativa, formerly known as: Medicago sativa, also known as: Medicago sativa, Latin name: Medicago sativa Rosaceae, Fabaceae, Alfalfa is a perennial herb, with strong roots, deep into the soil, and well-developed root necks. The stems are erect, clustered or even recumbent, quadrangular, glabrous or slightly pilose, with lush branches and leaves. [0003] Alfalfa is known as the "king of forage grass". It is a long-day plant with strong resistance and long service life (5-7 years). From the analysis of biomass, alfalfa can mow 3-4 crops per year, which is 2-3 times higher than that of cereals; the crude protein content of alfalfa dry matter can reach 18-20%, and the annual protein output per mu is more than 300 kg, which is higher than that of cereals. 50% higher, planting alfalfa is...
