Culture method for plant seedlings

Abstract

The invention relates to a culture method for plant seedlings. The plant seedlings are cultured by a ventilated root division culture device, the side surfaces of two culture bowls of the device are in butt joint, a cover plate and a culture plate are arranged on the two culture bowls, culture holes are formed in the culture plate, and vent holes are formed in the two sides of the culture holes. The culture method comprises the followings steps: the plant seedlings of 3 days are taken and cultured in a Hoagland's nutrient solution with the concentration of 50 percent for 2 days then in a Hoagland's nutrient solution with the concentration of 100 percent for 12 days, the plant seedlings growing consistently are taken, the stems of the plant seedlings are wrapped by nutrient cotton and fixed in the culture holes of the culture plate, the roots of the plant seedlings are divided into a group A and a group B, the group A is put into the culture bowl containing the Hoagland's nutrient solution, and the group B is put into the culture bowl containing a nutritional deficiency nutrient solution; the pH values of the nutrient solutions are regulated to 6 at 8 o'clock in the morning and 15 o'clock in the afternoon; the nutrient solutions are changed every other three days; and after 4-12 days, the plant seedlings are taken out. The operation is simple, and the personal errors are reduced, so that the research result is more accurate, the culture time is saved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a method for cultivating plants, in particular to a method for cultivating plant seedlings by using a plant split-root cultivating device. Background technique [0002] Plant split root culture technology is widely used in many aspects such as the physiological function of plant nutrients, the movement of nutrients in plants, the effect of nutrients on the growth and development of plant roots, the signal perception and conduction of nutrient deficiency, and the expression of root genes. The technology relates to a simple plant root division cultivating device and a plant seedling cultivating method. The traditional method of cultivating plant seedlings using a split-root cultivation device is to fix the plant seedlings on a planting board, and the nutrient solution cultivation pot is separated into two nutrition rooms through a middle partition. This method and device are inconvenient for fixing plant seedlings. At the same t...

Problems solved by technology

The traditional method of cultivating plant seedlings using a split-root cultivation device is to fix the plant seedlings on a planting board, and the nutrient solution cultivation pot is separated into two nutrition rooms through a middle partition. This method and device are inconvenient for fixing plant seedlings. At the same time, when fixing the seedlings, it will affect the fixing of other seedlings. When adjusting the pH value of the solution and changing the nutrient solution, it is easy for one nutrient solution to splash into another nutrient solution, resulting in inaccurate test results and inconvenient direct observation of the solution. There are many interference factors and large errors in the growth of the middle root system and the cultivation process. The structure of the previous split root cultivation device is not reasonable, it is inconvenient to operate, the work efficiency is low, and the labor consumption is increased.
