When farmers turn to the ground to reduce labor intensity, they use rotary cultivators to turn the ground. However, according to a survey conducted by the reporter, the effect of using different rotary cultivator blades to turn the floor is not the same. The vegetable cultivator should use the right rotary plough blades according to his own needs.
When fertilizing the soil before the high-temperature stuffy shed, the vegetable grower can use a straight hook-shaped rotary knife. It is understood that this kind of rotary knife can turn the fertilizer spread on the surface into deep soil, and the fertilizer can be more evenly turned into the tillage layer. At the same time, the soil clod produced when turning over the ground is large, which is also conducive to the downward movement of heat. Conduction to enhance the drapery effect. Moreover, the use of a straight hook-shaped rotary knife is effective for breaking the soil plow bottom layer, especially for soils with poor soil viscosity and permeability to water.
The left and right machete blades, which are bent on the head of the rotary cultivator blade and have a long blade on the outer arc, are currently the most widely used type of blades. The cutting ability of the blade is strong, and the clods caused by turning the ground are fine, but the depth of tillage is limited, only about 15 centimeters. Using this type of rotary cultivator for a long time may easily cause the ground of the soil plow to be too shallow, which is not conducive to the vegetable root system. tie. Moreover, such blades have poor soil-turning ability and it is difficult to turn the manure applied to the soil into the underlying soil. The reporters found that when using this type of blade to turn the ground, manure is mostly distributed in the soil within 10 cm, and the distribution is concentrated, which is not only prone to burning seedlings, but also is not conducive to guiding roots under the bar, plant growth potential difference. Therefore, it is not advisable for vegetable growers to use the rotary cultivator with such blades to turn the floor.
