The invention discloses a method for cultivating schisandra chinensis. The method includes the steps that a forest of wild schisandra chinensis is selected on a mountain, 1500-2000 breeding parental plants are reserved, and other plants are removed; then, at the flowering phase of the next year, cross pollination and repeated crossing pollination are conducted on the reserved breeding parental plants, 1000-2000 excellent seeds are selected for growing seedlings after fruits are grown, and flat ground open-air cultivation and domestication are carried out under a full exposure condition; trunks of the seedlings need to be cut as low as possible in domestication, each seedling can germinate 3-4 main vines from a base part, slight cutting is conducted in the growing process, and an erected support is full of branches and tendrils; at last, seedling growing and planting are conducted on the seeds grown by the schisandra chinensis which is subjected to cultivation and domestication, and accordingly a schisandra chinensis variety is obtained. The schisandra chinensis variety cultivated through the method has obvious stress resistance, and the schisandra chinensis can still grow normally under the high temperature and slight arid condition; meanwhile, the yield of the cultivated schisandra chinensis is improved obviously compared with the yield of the wild schisandra chinensis, and the yield is about 1.3 times of the yield of the wild schisandra chinensis.

The invention discloses a domestication method for hydroponics flowers. The domestication method includes the following steps that root systems of the flowers are planted into water media to be subjected to seedling recovering treatment, and the planting depth of the flowers into the water media needs to satisfy the condition that the root systems can at least expose in air partially to grow aerial roots; the flowers after seedling recovering treatment are subjected to hydroponics planting. According to the domestication method for the hydroponics flowers, first, the flowers with the root systems fixed through fixing devices are planted into the water media to be subjected to seedling recovering treatment, part of root systems expose in the air during seedling recovering treatment to induce the aerial roots, the flowers can adapt to the water environment primarily through seedling recovering treatment, the certain quantity of aerial roots with ventilating tissue grow out, then the flowers completely adapt to the water environment through hydroponics planting, and therefore the training effect is improved.

The invention discloses an evening primrose cultivation method. The evening primrose cultivation method comprises the steps of 1, seed treatment, wherein seeds are soaked with cold water for 1-2 hours, bailed and put into a bag, the bag with the seeds is put at the temperature of -10 DEG C for 24 hours, and then the seeds are taken out and air-dried for standby; 2, sowing, wherein the seeds treated in the step 1 are soaked with water for 5-6 hours, a land mass where the soil is fertile and flood drainage is easy are bedded and ridged to serve as a seedbed with the width of 1.2 meters, the landmass is thoroughly watered one time, after water permeates, 1-5 g/m<2> seeds are uniformly broadcast each time, and after broadcasting is completed, the seeds are covered with a covering with the thickness of 0.2-0.4 centimeter; 3, seedling raising, wherein the seeds in the step 2 grow seedlings, when there are six leaves on each seedling, the spacing between the seedlings is fixed to 4-5 centimeters, and when the seedlings are 50-60 days old, and the heights of the seedlings are 10-15 centimeters, the seedlings are transplanted in field; 4, transplanting, wherein the seedlings in the step 3are transplanted in the field, 1-2 plants are planted in each hole, and the spacing in the rows and spacing between rows are 50 centimeters and 60 centimeters. The evening primrose cultivation methodhas the advantages that seed introduction and domestication cultivation research on evening primrose are conducted, the growing adaptability and the biological characteristics of the evening primroseare improved, and the evening primrose is conveniently popularized, demonstrated and planted especially in the Karst region.

The invention provides a zooplankton culture device. The zooplankton culture device comprises a support, at least one floating body fixed to the support, a culture cabin, a first suction pump, a water inlet pipeline and a induction light source; the culture cabin is fixed to the support, the culture cabin is in an open shape and comprises a pump chamber, a domestication chamber, a first breeding chamber and a second breeding chamber, the first breeding chamber and the second breeding chamber are located between the pump chamber and the domestication chamber, the bottoms of the first breeding chamber and the second breeding chamber are in communication connection, wherein the first breeding chamber is closer to the pump chamber than the second breeding chamber, the second breeding chamber communicates with the top of the domestication chamber, a water inlet screen plate is arranged at the bottom of the pump chamber, and the domestication chamber is provided with a water outlet; the first suction pump is arranged on the water inlet screen plate; the water inlet pipeline is connected with the first suction pump, and a water outlet of the water inlet pipeline is positioned above the first breeding chamber; the induction light source is positioned in the second breeding chamber.

The invention provides ceramic membrane sewage treatment equipment and method based on domestication of active microorganisms. The equipment comprises a reaction tank which comprises a water inlet anda water outlet; a first membrane assembly, of which a ceramic membrane is communicated with a gas storage tank through a gas pipeline and is filled with microorganism culture gas in the gas storage tank, wherein a biological membrane layer is formed in an activated sludge environment, and the surface of the ceramic membrane of the first membrane assembly is covered with the biological membrane layer; and a second membrane assembly which is located at the downstream of the first membrane assembly, and the second membrane assembly is communicated with the water outlet through a water outlet pipeline. According to the invention, the problem of uncontrollable microbial population in the existing MBR technology is solved, and the problems of low water production rate and frequent replacement of the membrane assembly caused by easy pollution of suspended activated sludge to the membrane assembly in the existing MBR can be solved as the immobilized microorganisms are adopted to treat wastewater and have low sludge yield and good settling performance.
