摘要:
The present invention discloses a plant culture device. The plant culture device comprises a culture box body and a partition plate; the partition plate is arranged in a middle part of the culture boxbody so as to divide the culture box body into an upper external root absorption space and a lower root system absorption space; and the external root absorption space part in the culture box body isprovided with a ventilation opening and a liquid discharge opening, the root system absorption space part in the culture box body is provided with a water inlet and a water outlet, planting holes arearranged in the partition plate, and the liquid discharge opening is suitable for discharging liquid stored in the overground part absorption space. The plant culture device can separate the root system absorption space and the external root absorption space of plants so as to research substances such as nutrients, etc. separately absorbed by plant root system, overground stems, leaves, fruits, etc. in plant growth process from the external environment, transportation and accumulation mechanisms of the absorbed substances in plant body, and comparisons of contributions of root system absorption paths and external root absorption paths to element accumulation in the plant body.

The invention belongs to the technical field of powder milling and crushing, and particularly provides a ball milling tank with an ellipsoid-like inner cavity. The ball milling tank comprises a tank body and a tank cover, wherein the inner cavity of the ball milling tank is formed by the tank body and the inner cavity of the tank cover together. The inner cavity of the ball milling tank is an ellipsoid-like cavity obtained by stretching an ellipsoidal cavity upwards and downwards to the same height along the horizontal symmetry axis of an ellipsoid. According to the ball milling tank with theellipsoid-like inner cavity, the friction between materials and the inner wall can be increased, the ball milling is more uniform, the energy is larger, and the problems such as material sinking and agglomeration are solved.

The invention discloses a melon and fruit antiseptic and fresh-keeping agent. The antiseptic and fresh-keeping agent comprises the following raw materials: 0.04%-0.1% parts of scutellaria baicalensisextract, 0.1%-0.15% parts of clove oil, 0.04%-0.1% parts of cinnamon oil, 0.05%-0.1% parts of saponin extract, 0.15%-0.2% parts of patchouli oil, 0.15%-0.2% parts of calamus oil, 0.3%-0.5% parts of camellia meal extract, 1.3%-5.5% parts of emulsification thickener, 2.3%-7% parts of other additives, the balance water, and the total amount of raw materials is 100%. The invention also discloses a kiwi fruit antiseptic and fresh-keeping agent, a preparation method thereof and a melon and a melon and fruit storage method. The raw materials of the plant-derived antiseptic and fresh-keeping agent ofthe present invention are all plant-derived extracts, without any chemical organic reagents, and have good antiseptic and fresh-keeping effect. After being mixed with water, the agent can be used to form a film on the surface of fruits and vegetables to inhibit the growth of pathogenic bacteria. At the same time, the film can reduce and inhibit the physiological metabolism of the fruit after harvest, thereby improving the quality of the fruit, and extending shelf life.

The invention discloses an intelligent vegetable aerial fog planting device which comprises a planting tank, an intelligent control system, a cultivation system and a nutrition liquid spraying supplyand backflow system, wherein the intelligent control system, the cultivation system and the nutrition liquid spraying supply and backflow system are mounted on the planting tank; the cultivation system comprises a plurality of cultivation shelves; the cultivation shelves are internally provided with cavities; fixed planting holes are formed in side surfaces of the cultivation shelves; fixed planting baskets for cultivating vegetables are mounted in the fixed planting holes; bottoms of the fixed planting baskets extend into the cavities; a nutrition liquid supply tank communicates with the cavities through nutrition liquid spraying conveying pipelines; and the cavities are connected with a nutrition liquid backflow tank through a nutrition liquid spraying backflow pipeline. The device is asoilless cultivation mode that demands of vegetable root systems on water and fertilizers are met through two modes of atomization and spraying of a nutrition liquid, the production efficiency of sealed aerial fog cultivation equipment can be improved, and the effective utilization rate of a three-dimensional space can be increased.
摘要:
The invention provides a low-temperature-resistant seed soaking agent for rice in a bud stage as well as a preparation method and application thereof. The rice bud stage low-temperature-resistant seedsoaking agent is formed by mixing an abscisic acid solution with the mass concentration of 9-11 mg/L, a monopotassium phosphate solution with the mass concentration of 5-7 g/L and a uniconazole solution with the mass concentration of 29-31 mg/L, wherein the volume ratio of the abscisic acid solution to the monopotassium phosphate solution to the uniconazole solution is (2-4): (1-3): (0.5-1.5). The low-temperature-resistant seed soaking agent for the rice in the bud stage can effectively improve the seedling rate and the strong seedling rate of rice seedlings at a low temperature, reduce the harm of the low temperature to the rice seedlings and achieve the effect of improving the low temperature resistance of the rice seedlings.
