Crop cultivation device facilitating plant spacing adjustment

Abstract

The invention discloses a crop cultivation device facilitating plant spacing adjustment, and belongs to the technical field of crop cultivation. The crop cultivation device can indirectly control a cultivation floating platform to adjust the plant spacing through an adjusting iron block by introducing a hydroponic mode and based on the suspension characteristic of the cultivation floating platform, the crop cultivation device is very convenient, and absorption of nutritional ingredients is more effective; meanwhile, a specially-arranged sensing floating ball can sense the absorption condition of a nutrient solution, the density is reduced after nutritional ingredients are consumed to a certain degree, the sensing floating ball sinks to pull a supplementing ball bin to release special nutrients, and the special nutrients are received and increased by the cultivation floating platform; and then, the cultivation floating platform also gradually sinks, so that the roots of the crops can absorb nutritional ingredients deposited at the water bottom, finally, after the cultivation floating platform is in direct contact with the water bottom, a multi-section ejector rod triggers the release action of nutrients to restore the density, then the cultivation floating platform and the sensing floating ball are reset again to start normal cultivation, the cultivation cost of the crops can be effectively controlled, and the absorption effect on the nutritional ingredients is improved.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, and more specifically relates to a crop cultivation device which is convenient for adjusting the distance between plants. Background technique [0002] Crops are various plants cultivated in agriculture. Including food crops and economic crops (oil crops, vegetable crops, flowers, grass, trees) two categories. Man regards food as his heaven, which expresses the relationship between man and food, and only a reasonable diet can bring health to human beings. The growth of crops is inseparable from scientific and technological production technologies, as well as machinery and equipment manufactured by new industries that can assist agricultural production. [0003] The so-called plant spacing is the planting distance between two plants. The plant spacing required by each plant is different, mainly depending on the degree of sunlight and nutrient absorption of each plant. When sowing plants...

Problems solved by technology

[0004] However, most of the existing crops are cultivated in soil. Not only the crops have limited absorption of nutrients, but also it is difficult to adjust the distance between the plants. It can only set a larger distance between the plants in the early stage of growth, resulting in a low space utilization rate and leading to poor cultivation of crops. Increased costs
