Description

Technical Field

[0001] The utility model belongs to the technical field of water and fertilizer supply, and particularly relates to a farmland soil turning and water and fertilizer supply device. Background Art

[0002] Greenhouse tillage is a type of farmland tillage, which refers to a series of agricultural work such as turning, tilling, and leveling the soil in the greenhouse to achieve the effect of improving soil quality and increasing crop yields. It includes several aspects such as preparation before greenhouse tillage, tillage methods, and soil management after tillage. Greenhouse tillage includes: manual tillage, which is carried out using tools such as shovels and hoes. The fluctuating soil depth is difficult to grasp, the labor intensity is high, and the time cost is high; mechanical tillage, currently commonly used are tractor-type and shovel-type machines, which are simple and convenient to operate and highly efficient. It should be selected according to local soil environment, crop requirements and uses.

[0003] The preparation work before turning the soil in the greenhouse includes: adding fertilizer. Adding an appropriate amount of chemical fertilizer can improve soil fertility, enhance the soil's ability to retain water and fertilizer, and promote crop growth; moistening the soil with water. A few days before turning the soil, watering can be carried out to allow the soil to fully absorb water and maintain appropriate humidity, laying a good foundation for turning the soil.

[0004] Recycled rainwater can be used for greenhouse farmland irrigation. First of all, agriculture does not have such high requirements for water sources. Those who have lived in rural areas know that most of the irrigation of rural farmland comes from rainwater or water in ponds, which is basically directly equal to recycled rainwater. Moreover, rainwater itself has natural nutrients. When using recycled rainwater to irrigate crops, it can also improve the growth quality of crops. Using rainwater for agricultural irrigation can reduce dependence on groundwater and also achieve the effect of saving water resources.

[0005] In the prior art, most of the rainwater collection devices for greenhouses only collect rainwater into a water tank for subsequent use, and their functions are relatively simple. When water and fertilizer need to be applied before turning the soil in the greenhouse, the water tank used for rainwater collection is indeed difficult to mix rainwater and fertilizer. Even if fertilizer is put into the water tank, it is difficult to fully dissolve and mix the rainwater and fertilizer due to the lack of a stirring component. Utility Model Content
