Embodiment Construction

[0017] A method for controlling temperature and humidity in rice seedling-raising greenhouses, comprising the following aspects:

[0018] (1) From sowing to the emergence stage, in order to ensure that the seedlings emerge neatly, the temperature in the shed should be controlled at 30°C, and at the same time, heat insulating agent should be applied to the soil. When the temperature exceeds 35°C, the temperature should be ventilated in time to prevent high-temperature steaming of buds;

[0019] (2) When raising seedlings in winter and spring, due to the low temperature, the mode of turning on the electric light in the greenhouse should be adopted to increase the temperature, and at the same time, straw should be covered outside the shed to ensure that the minimum temperature index required for each leaf age of the seedlings is reached;

[0020] (3) Seedling tray and air humidity are mainly based on spraying water, while spraying humectant on the leaf surface to ensure that the c...

Abstract

The invention discloses a method of controlling the temperature and the humidity of a rice seedling greenhouse. The method of controlling the temperature and the humidity of rice young seedlings disclosed by the invention is scientific and reasonable; a used technical means is suitable for the growth requirement of the rice young seedlings; a large amount of organic humus are added into a heat preservation agent, so that the buffering capacity of soil to temperature can be improved; the diurnal temperature difference is reduced; a plurality of raw materials added into a moisture preserving agent have high film-forming properties and high moisture preserving properties; after the moisture preserving agent is sprayed on leaf surfaces, film surfaces are generated to reduce the loss of water; meanwhile, the moisture preserving agent contains nutrients in a chelating state, and the nutrients are extremely easily absorbed by the leaf surfaces, and have an extremely strong assisting effect in accelerating the development of young seedlings; an active effect on increasing the yield of rice is achieved.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a method for controlling the temperature and humidity of a rice seedling-raising greenhouse. Background technique [0002] With the development of society and economy, the production situation of my country's rice has undergone profound changes, and it has become an inevitable trend to promote the mechanization of rice with machine transplanting as the key technical link. There have been many years of demonstration and promotion of machine-transplanted rice in my country, but it is still not popularized. There are many reasons for this. Among them, due to the high requirements for machine-transplanted seedlings, it has not been possible to cultivate standards that are suitable for both transplanting operations and high-yield agronomic requirements. Strong seedlings have become the biggest technical obstacle. [0003] The quality of seedlings plays an important role in the number...
