Orchard grass cultivation is an ecological cultivation technique that has been advocated for many years. Without increasing organic fertilizer, the content of humus in the orchard soil can be maintained at 1% or more; at the same time, the loss of soil, fertilizer and water can be reduced, and the rain can be relieved. The harm to fruit trees is conducive to the formation of a good orchard microclimate and improved fruit quality. Orchard grass is simple to say. In fact, there are a lot of knowledge in it. Today we will talk about it in detail.
What kind of orchard can grow grass
For our province, most of the orchards can grow grass in accordance with local conditions. However, in dry areas, especially in areas where the annual precipitation is below 550 mm, it is not appropriate for the entire garden to grow grass. Orchard grass is divided into natural grass and artificial grass. As for which method to choose, it depends on the specific circumstances. Natural grasses have low input, but they do not require high irrigation conditions, but they cannot choose grasses. Artificial grasses can be planted selectively, but this requires certain economic strength and management level.
What kind of grass in the orchard?
At present, there are many types of grass suitable for orchard cultivation. The general requirements are dwarfing or breeding, strong adaptability, resistance to yin, resistance to trampling, low water consumption, no joint pests and diseases with fruit trees, and the ability to attract natural enemies. Herbs are preferred because legumes have a nitrogen-fixing effect that increases the amount of nitrogen in the soil. At present, more legumes are planted with pods, white clover, grass rhino, and wild peas. In addition, ryegrass, Dactylis, rat grass and zoysia can also be planted in the orchards.
Weeding between rows, weeding under trees
In addition to the conditions mentioned above, the orchards also need to pay attention to some details: the grass under the fruit trees should be removed, and grass and grass must be kept between the rows. Before the new orchard is built, it must be well designed and the distance between the rows should be larger. In the orchards with high plain and organic matter content, the amount of grass can be reduced.
How to manage water and fertilizer after weeding
No matter weeds or grasses are grown, they will inevitably compete with fruit trees to compete for water. Therefore, the orchard of the grass must be well managed. In the orchard orchard with irrigation conditions, the fertilizer solution can be sprayed directly onto the grass during fertilization, and the grasshopper can be rotted and then converted into organic fertilizer to be absorbed by the fruit tree. In order to speed up the transformation of the grass, generally productive orchards require 10-20 kilograms of nitrogen fertilizer per acre.
Will grasses cause more pests and diseases?
There are many varieties and quantities of grass on the ground. The general insects are willing to stay in the grass and mainly use herbivores. On the contrary, if the grass is cut off, that is, after ploughing, the insects lose their “homeland†and have to go to the tree. Therefore, in general, the grass in the orchard is beneficial to pest control. If there are more pests in the area, especially if there are more overwintering pests, after the grass is cut off, regular pesticides must be sprayed at the end of autumn or March of the following year. In addition, in order to prevent insect pests, artificial grasses require more than three species of grass to be planted.
How to cut grass in the orchard
When weeds grow more than 20 centimeters, they must be castrated in a timely manner. Usually, they are castrated 2-4 times a year. Legumes should be kept more than 15 centimeters, and grass should be about 10 centimeters. The grass was full of grass, and the cut grass was scattered in the ground or covered around the fruit trees, 20-30 centimeters from the trunk of fruit trees.
