To protect the ecosystem, farmers living on the banks of the Yangtze River have begun to dramatically reduce the use of chemicals and adopt biological pest control methods. Orange farmer Ran Xiaoli's orchard of navel oranges on the south bank of the river is a good example.

In addition to insect-trapping balls, solar-powered lamps and sticky cards, a special type of mite has been introduced to kill pests. One of the predatory mites, the size of a sesame seed, can eat an insect, such as a red spider, that's two or three times its size. A bag of 1,500 mites can kill all the pests on a citrus tree.

Ran, 37, is also director of Huolong, a community in Chongqing's Yunyang County. In 2005, she was the first in the area to plant orange trees and promoted the idea of green agriculture. Many fields had been abandoned, as young farmers left to work in the cities. Left-behind seniors grew traditional crops such as corn and rice. Some planted peach and plum trees. "Different crops and fruit trees need different types of pesticides and fertilizer," Ran said. "The total amount of chemicals used by the farmers was huge, which severely damaged the soil and water."

After some research, she decided to try growing oranges using as few chemicals as possible. Her success encouraged people in the community. Now, about 80 percent of the residents have joined her. "In the past, we spread pesticide five times a year," she said. "Now we use it only once or twice a year."

The world's third-longest river, the Yangtze stretches 6,300 kilometers from the glaciers of the Qinghai-Tibet Plateau eastward through Chongqing, Wuhan and Nanjing before reaching the East China Sea at Shanghai. More than 400 million people get their drinking water from the Yangtze, and water security has become a major issue in China's development. President Xi has attached great importance to restoring the river's ecology, and urged officials from provinces along the river to concentrate on restoration and protection, and to avoid large-scale development.

Chongqing, located in the upper reaches of the Yangtze, is among the 11 provinces and cities in the Yangtze River Economic Belt, a key national development strategy that has made ecological protection its most important mission. Orange farming has become popular in Chongqing and the Three Gorges Reservoir area. Wanzhou district in northeast Chongqing began building a national agricultural park to demonstrate the green agriculture concept in 2017. "It can help reduce the use of pesticides and improve air quality," said Wang Xiaowei, who works in the fruit tree department of the Wanzhou Agricultural Commission. "Farmers also make more money from those organic products."

為了保護生態系統,生活在長江岸邊的農民已經開始大幅減少化學品的使用並採用生物害蟲防治方法。橘子農夫冉小莉在河南岸的臍橙果園就是一個很好的例子。

除了昆蟲誘捕球,太陽能燈和粘卡之外,果園還引入了一種特殊品種的蟎來殺死害蟲。 其中一種掠食性蟎蟲,芝麻種子的大小,可以吃掉一整只昆蟲,如紅蜘蛛,而紅蜘蛛的大小是其兩到三倍。 一袋1500個蟎蟲可以殺死柑橘樹上的所有害蟲。

37歲的冉小莉是重慶雲陽縣火龍社區的主任。 2005年,她是該地區第一個種植橙樹並推廣綠色農業的人。因為年輕人紛紛投奔大城市,許多農田被遺棄。一些留守老人種植了玉米和大米等傳統作物,當然還有桃子和李子樹。“不同的作物和果樹需要不同類型的農藥和肥料,”Ran說。 “農民使用的化學品總量巨大,嚴重破壞了土壤和水。”

經過一番研究,她決定嘗試使用盡可能少的化學品來種植柳丁,她的成功鼓勵了社區裡的人,現在約有80%的居民加入了她。“過去,我們每年噴五次殺蟲劑,”她說。“現在我們每年只使用一到兩次。”

長江是世界第三長的河流,從青藏高原的冰川向東延伸6300公里,穿過重慶,武漢和南京,然後匯入上海的東海。超過4億人從長江獲取飲用水,水安全已成為中國發展的一個主要問題。習近平主席非常重視恢復河流生態,並敦促沿江省的官員集中精力進行恢復和保護,避免大規模開發。

重慶位於長江上游,是長江經濟帶的11個省市之一,是國家重點發展戰略,肩負著生態保護的重要使命。橙色農業已經在重慶和三峽庫區開始流行起來。重慶東北部萬州區於2017年開始建設國家農業園區,踐行綠色農業理念。“橙色農業減少農藥的使用,改善空氣品質,”在萬州農業委員會果樹部門工作的王曉薇說。“農民也從這些有機產品中賺到更多錢。”
