"All living things depend on lighting" -- A discussion on using light to nurture the plant world

咋看这个题目有点“唬人”，似乎也有点“天方夜潭”，其实随着第三代半导体的LED脱颖而出（没有卡脖子问题），什么全光谱？什么多基色？什么去荧光粉的纯LED之光等应运而生。

在地球上，万物生长靠太阳，看似当正确，其实不然。尤其有了LED之光后，这个世界似乎会改变一些模样，光靠太阳显然不够，日出还要日落，白天还有黑夜。而灯光呢？只要你想，便可随心所欲地因需用光。

For example: rice is typically double-cropped in Jiangnan, but can reach up to four seasons in Hainan. If MLS Co., Ltd.'s plant cabin and plant lighting are used, cultivation under "persona-based light" inside the cabin can yield six harvests per year. This has already been demonstrated at the National 13th Five-Year Plan Achievement Exhibition. Of course, this is led by the team of Mr. Yang Qichang, known as the father of plant factories from the Chinese Academy of Agricultural Sciences. Calculated, it amounts to 60 days per crop cycle, with up to six cycles per year.

We deeply respect Academician Yuan Longping, who worked tirelessly to cultivate hybrid rice, braving wind and rain, relying on nature for trials. If this were today, it would be much simpler. Using a plant chamber, also known as a breeding accelerator, equipped with dedicated LED lights and an AI control system, could we not accelerate breeding trials? A few days ago, I was delighted to see corn cobs ready in just 70 days. Imagine if such high-tech methods were widely adopted; what vast development opportunities would exist beyond the 1.8 billion mu of arable land! Could we test planting Gobi rice, wheat, triticale, and even barley in places like Xinjiang?

The barley seedlings currently favored by the world, when one ton of seeds is soaked in water, can grow 16-18 cm within six to seven days, yielding 6 to 8 tons of seedlings. Cattle and sheep eagerly consume the fresh green grass, especially during the harsh winter season when it is particularly precious. According to our collaborative trials with livestock experts, adding 1 kg/day (fresh wheatgrass) to dairy cows' diet increases milk production by 0.74 kg/day (fresh milk). If widely adopted, just as for humans, livestock could enjoy fresh grass every day of the year, ensuring even higher quality milk.

已故领袖曾说过：“农业的根本出路在于机械化”，今天是否在机械化上加上垂直化和智慧化呢？

Since the outbreak of the COVID-19 pandemic, despite our excellent protective measures, outbreaks can still occur unexpectedly, requiring us to implement static management. If our streets and residential communities had plant pods, could we not simply "harvest vegetables directly from the pod"? Moreover, Shanghai is gradually becoming an aging city; providing unified meals for elderly residents has become essential. Equipping them with rapid-growth vegetable pods or mushroom pods would be incredibly convenient and safe!

万物生长靠太阳，当然这句话仍然是“对”的。在靠太阳(大自然赐予的)的同时，灯光有辅助的补光作用。当然灯光，也可比拟作全天候的阳光。

Lighting up the world, we lighting professionals have achieved it; nurturing the plant world with light, this work is only the beginning of a new long march. Friends with shared ideals, let us join together!
