Growing grass for pasture is a high-tech agricultural endeavor, far from simple as many might imagine.

Originating in Western countries, pasture grass cultivation requires precise matching of geographical conditions such as light exposure, intensity, temperature fluctuations, and soil types.

In the rapid development of this industry, grassland machinery has played an irreplaceable role, yet it also presents numerous challenges that require continuous exploration to resolve. The mechanization of grassland production involves multiple operational stages with high technical requirements, directly impacting the economic viability and development of the pasture industry.

Mechanized techniques for grass planting primarily utilize machinery to optimize the planting, management, harvesting, and utilization of grass, thereby increasing yield and optimizing grass structure.

In terms of practical application, this technology not only facilitates the sowing of different grass seeds but also significantly improves the physical and chemical properties of grassland soil through operations such as loosening, cutting, pressing, and fertilizing. This enhances soil fertility, and water retention capacity, and ensures high germination and survival rates, thereby improving the yield and quality of pasture.

Key technical points include:

1. In rotational grazing areas, plowing, harrowing, sowing, and fertilizing operations should have a depth requirement of 18-22 centimeters, while in shallow tillage areas for pasture, the depth should be 15-17 centimeters. Harrowing should be performed twice, both heavy and light, in a diagonal direction, followed by pressing.

2. For reseeding operations, the depth of loosening should generally be between 15-25 centimeters, with a larger range being preferable. Care should be taken to avoid damaging the original grass vegetation, and grooving should be minimal with a smooth surface.

3. Reseeding should ideally be carried out during the weakest growth period of existing plants to minimize their inhibitory effects. Spring and summer are generally suitable for reseeding, although in colder regions, "seed resting" before freezing can also be employed.

4. Seed quantities vary for different grass families (according to their characteristics), with grasses like black ryegrass requiring 5-6 pounds per acre, while legumes like alfalfa need 3-4 pounds per acre. Additional seeding may be necessary in natural grasslands due to low germination rates.

Some grass seeds require pre-sowing treatments such as cleaning, mixing, and soaking (e.g., alfalfa, rume grass, Mexican corn grass).

5. Sowing depth varies depending on soil density and seed size, typically not exceeding 3-4 centimeters for grasses and 1-2 centimeters for legumes.

Supporting machinery for grass planting mechanization primarily includes specialized equipment for plowing, sowing, and pressing, as well as combined loosening and reseeding machines. Other traditional agricultural machinery can be used for soil preparation and grain-grass sowing operations. Specialized grass plowing and sowing machines can be categorized based on seeding methods (row seeding or broadcast seeding) and loosening methods (shovel or powered disc).

When arranging the operation process and matching machinery, considerations should be made to improve efficiency while also aligning with soil conditions and the types of machinery available.
