117 results about "Windbreak" patented technology

A windbreak (shelterbelt) is a planting usually made up of one or more rows of trees or shrubs planted in such a manner as to provide shelter from the wind and to protect soil from erosion. They are commonly planted in hedgerows around the edges of fields on farms. If designed properly, windbreaks around a home can reduce the cost of heating and cooling and save energy. Windbreaks are also planted to help keep snow from drifting onto roadways or yards. Farmers sometimes use windbreaks to keep snow drifts on farm land that will provide water when the snow melts in the spring. Other benefits include contributing to a microclimate around crops (with slightly less drying and chilling at night), providing habitat for wildlife, and, in some regions, providing wood if the trees are harvested.

Fast planting and high frequency mowing cultivation method of alfalfa in desert edge windbreak-free forest

PendingCN122623575AWindbreakNutrient solution
This invention discloses a rapid establishment and high-frequency harvesting method for alfalfa cultivation on desert edges without the need for windbreaks, belonging to the field of sandy land ecological agriculture and forage cultivation technology. This method is suitable for shifting sandy areas on desert edges, eliminating the need for windbreaks. Early-maturing forage oats are sown in single rows in spring. After the oats reach a height of 10-20cm and form a windbreak barrier, drought- and salt-tolerant alfalfa is sown in rows between the rows. Drip or sprinkler irrigation is used, and nitrogen, phosphorus, and potassium fertilizers are reduced by 20%-30% compared to conventional methods. Three to five days after each alfalfa harvest, a nutrient solution containing enzymatically hydrolyzed animal-derived small molecule peptides with a molecular weight <1000Da is applied with irrigation water. The oats are harvested in one go after maturity; the alfalfa is harvested frequently when the plants reach a height of 50-60cm, with 5-6 harvests per year. This invention utilizes oats for temporary wind protection, resulting in a lower than 15% mortality rate from wind and sand during the alfalfa seedling stage, enabling planting in the same year. The hay has a crude protein content of 19%–22%, a yield of over 1200 kg of hay per mu, and can be harvested continuously for 8–10 years. It is suitable for desert edge areas with annual precipitation <100 mm.

Sand-fixing method using haloxylon type pruning and sand burying

This invention discloses a sand-fixing method utilizing coppicing and sand burial of Haloxylon ammodendron, relating to the fields of windbreak, sand fixation, and vegetation restoration. Based on the natural growth angle of Haloxylon ammodendron branches, this invention applies coppicing and layering treatments to upright and inclined branches respectively. Inclined branches are laid flat against the ground and buried in sand, causing adventitious roots to sprout from the buried internodes and new suckers to grow upwards. These newly formed suckers are guided towards adjacent plants and buried perpendicular to the prevailing wind direction, creating a connected network structure between plants through their root systems and stolons. This invention classifies and treats branches according to their type. Coppicing upright branches reduces plant height and branch height, promoting tillering; sand burial of inclined branches induces adventitious roots, expands the water absorption area, lowers the center of gravity of branches and leaves, and increases ground cover, which is beneficial for improving the sand-fixing efficiency of vegetation, enhancing the water use efficiency of Haloxylon ammodendron, and promoting healthy shrub development.
