Method for controlling rice seedling growth by optical spectrum, and raising spectrum regulating appliance and equipment

Abstract

The invention provides a method for controlling rice seedling growth by optical spectrum. According to the technical scheme, the method includes distributing light emitting diodes on two sides and / or over a paddy field to allow the sides and top of rice seedlings to be irradiated by the light emitting diodes; allowing both red light emitting diodes and blue light emitting diodes in the light emitting diodes to be distributed on the sides and / or over the paddy field; and controlling the red light emitting diodes and the blue light emitting diodes to emit light in the raising stage to regulate seedling growth and make the seedlings grow healthily so as to raise strong seedlings. The LEDs are used as a light source to supplement lighting and control growth of the rice seedlings, so that the problem that consumption of common light energy is high is solved. The LEDs serving as the light source can be designed to be able to emit single light, the targeted LEDs with spectrum required by growth of the seedlings are selected to serve as the light source, and accordingly energy consumption is lowered and utilization rate of the light source is increased substantially.

Description

technical field [0001] The invention relates to rice planting technology, in particular to a method, device and equipment for regulating the growth of rice seedlings. Background technique [0002] With the development of society and economy, mechanized transplanting of rice is becoming the main way of rice cultivation in my country. Especially in line with the development and application of machine-transplanted rice technology, the industrialized seedling-raising centers with greenhouse and greenhouse seedling-raising facilities as the core have developed rapidly, improving the large-scale operation of rice machine-transplanted rice seedlings, the level of social services, the centralized supply of seedlings, and the standardization of rice seedling raising The level and efficiency of rice planting can be reduced, and the risk of traditional farmers' scattered seedling raising can be reduced. [0003] The standard rice seedlings for machine-transplanted rice require a gener...

Problems solved by technology

However, the sensitivity of different rice varieties to paclobutrazol is different. If the amount of paclobutrazol used is too small, the effect of seedling height control is not good, and if the amount of paclobutrazol is used too much, the growth of seedlings will be excessively inhibited, which will affect the later growth.

In addition, the residual time of paclobutrazol in the soil is very long, and the continuous use of paclobutrazol will cause paclobutrazol to accumulate in the farmland soil, which is likely to have a bad inhibitory effect on subsequent crops

[0004] Seedling raising in greenhouses and greenhouses is prone to leggy growth due to insufficient light, and the use of ordinary light sources consumes a lot of energy and cannot control the growth of seedlings
