[0002] The main components of general liquid mulch are lignin, cellulose, etc., which have a certain effect of heat preservation and water retention on the soil. However, when spraying liquid mulch on plants after planting (such as tomatoes, cucumbers, etc.), it is easy to spray the liquid on the stems and leaves of the plants, which may affect the photosynthesis and growth and development of the plants. At present, the spraying equipment of liquid mulch is mainly concentrated on crops planted in the open air, such as corn, wheat, peanuts, etc., and special liquid mulch spraying equipment for greenhouses is relatively rare. In addition, the cost of equipment specifically suitable for spraying mulch on planting crops is relatively high. Under the condition of high investment, the promotion of liquid mulch is limited.
[0003] Traditional nozzles can only spray in a directional manner, with a fixed spraying distance and range, and are generally used to spray from above the crops. When using traditional sprayers to spray liquid mulch, on the one hand, it is impossible to avoid plant stems and leaves, and most of the liquid mulch is blocked by plants during the spraying process and cannot cover the soil surface, resulting in low utilization of the liquid mulch; on the other hand, if the liquid mulch is accidentally sprayed on the stems and leaves of plants, it may have an adverse effect on the growth of the plants.
[0004] Therefore, a handheld agricultural liquid mulch sprayer was developed. This device can not only be easily installed on the common drug spraying device on the market, but also can be extended into the space between plant rows and spray close to the ground, reducing the impact of liquid mulch spraying on the stems and leaves of seedlings. It has low cost and simple factory processing technology, which is more conducive to market operation and lowers the threshold for the use of liquid mulch. Utility Model Content
