The invention discloses a device and method for measuring the respiration rate of a fruit, and relates to the technical field of fruit respiration rate measurement. The device comprises a closed CO2 assimilation chamber and a photosynthesis tester, the photosynthesis tester is provided with two CO2 detectors, one end of a gas inlet pipeline and one end of a gas outlet pipeline are connected with the CO2 detectors respectively, the other end of the gas inlet pipeline and the other end of the gas outlet pipeline are communicated with the CO2 assimilation chamber, CO2 is introduced through the gas inlet pipeline, and during measurement, the fruit is placed in the closed CO2 assimilation chamber, and variation of CO2 in the CO2 assimilation chamber represents difference generated by the respiration of the fruit. The device is in a sealed state during measurement, and the measured data is accurate. A support is arranged under the assimilation chamber, so that the assimilation chamber can leave a test bed, the gas inlet pipeline and the gas outlet pipeline are connected to the bottom of the assimilation chamber, gas is introduced in the lower portion, and is mixed uniformly by a fan. Viathe method of the invention, the respiration rate of the fruit can be measured rapidly and accurately, and basis is provided for storage condition setting and further research of the fruits after harvesting.

The invention relates to a large-ridge platform kidney bean cultivation method, and belongs to the technical field of kidney bean cultivation. Soil preparation and ridging are performed in autumn, field ditches are arranged on the two sides of a ridge, a ridge platform is arranged on the ridge, the field ditches and the middle of the ridge platform are subjected to deep scarification, the land surface before ridging is adopted as the reference, the ridge deep scarification depth is 30-40 cm, and the deep scarification depth of the middle of the ridge is 15-30 cm; during soil preparation, the base fertilizer is applied to the middle of the ridge platform; the seed fertilizer is applied below the position of seed sowing; kidney bean seed sowing is performed on the ridge platform, seed sowing is performed on three rows, three seedling belts are formed, the seed sowing line spacing is 25-30 cm, the variety of kidney beans is erected or half-spreading type lodging-resistance high-yield kidney bean variety; the topdressing is applied to the outer sides of the seedling belts on the left and right sides of the ridge, and the topdressing is applied below the ridge platform. Due to the cultivation method of the combination of deep scarification, seed sowing and fertilizer application, the permeability is good, the stress resistance is strong, the production efficiency and fertilizer using efficiency of the kidney bean group photosynthesis are improved, and the high yield, high quality and efficient production can be achieved.

The invention discloses a carbon neutralization combined cycle device. The device comprises a boiler, a flue gas pipeline and an induced draft fan which are sequentially connected, an outlet of the induced draft fan is connected with greenhouses through pipelines, the number of the pipelines and the number of the greenhouses are multiple, and each pipeline corresponds to one greenhouse. The induced draft fan and the distributed pipelines are directly connected with inlets of the greenhouses, the induced draft fan can adjust the flue gas amount in a variable frequency manner, flue gas enters the plurality of greenhouses through the induced draft fan and the distributed pipelines through design, CO2 and a heat source penetrate through crops such as fungus grass or forage grass and other various plants, under the action of a light source and the heat source, the temperature in the greenhouses is adjusted to be within the temperature range most suitable for the plants, the plants make direct contact with the CO2, photosynthesis and the like are rapidly generated, and the plants grow rapidly. The greenhouses utilize waste gas and waste heat, so that a large amount of operation cost is saved, the growth period of the crops such as the fungus grass or forage grass is shortened, and the yield is increased.

The invention relates to a microorganism and enzyme mixed preparation for stripping dirt of aquatic plants as well as a preparation method and application thereof. The microorganism and enzyme mixed preparation comprises citric acid, starch, carboxymethyl chitosan, bacillus subtilis, cellulase, cysteine and diatomite. The preparation method of the stripping agent comprises the following steps of: 1, sequentially adding the substances according to the proportion; 2, uniformly stirring for 15 minutes by using a V-shaped stirrer or a three-V stirrer; and 3, mixing the obtained mixture with pond water according to a mass ratio of 1: 100 to 1: 200, and uniformly stirring to obtain the microorganism and enzyme mixed preparation for stripping dirt of aquatic plants. Dirt on the surfaces of aquatic plants is rapidly removed, and photosynthesis is improved. A high-quality ecological environment rich in aquatic plants, which is clear in water, high in dissolved oxygen content in water and few in harmful substances in the water, is provided for cultured objects.

The invention discloses a method for enhancing microalgae carbon sequestration and oil production by using diethanol amine. The method comprises the following steps: introducing CO2 into a microalgae culture system, and adding diethanol amine to enhance CO2 gas dissolution and mass transfer and stress microalgae oil production; by adding diethanol amine, the capacity of the algae liquid for storing carbon dioxide is firstly improved, and then the mass transfer process of dissolving carbon dioxide in the algae liquid from air is accelerated, so that the photosynthesis of microalgae is favorably improved, and the increase of microalgae biomass is accelerated; in addition, oil production metabolism can be promoted through stress of diethanol amine on microalgae cells, so that the oil content of the cells is increased. Through promotion of biomass and cell oil content, the final yield (oil yield = biomass * cell oil content) of microalgae oil is improved.

The invention discloses a chimonanthus nitens disease prevention liquid and an application method thereof. The chimonanthus nitens disease prevention liquid is prepared from, by weight, 40-60 parts ofchimonanthus nitens bark or stems, 15-25 parts of garlic, 18-22 parts of ginger, 16-24 parts of rock candy and a plurality of parts of water. The chimonanthus nitens disease prevention liquid of theinvention is safe to human and livestock, and has significant effect; after spraying with the chimonanthus nitens disease prevention liquid, the virus replication of tobacco plants infected with mosaic diseases and horse Y diseases is inhibited, leaves grow normally, chlorophyll is increased, photosynthesis is enhanced, leaf dry matter accumulation is increased, it is guaranteed that tobacco leaves grow mature, and no pesticide residues exist; and the chimonanthus nitens disease prevention liquid is suitable for all peasant households and units for tobacco planting and suitable for popularization.
