A Chinese rice seed needs to undergo variety selection, alien species infringement risk analysis, and approval before it can go from China’s hybrid rice experimental fields in the northern hemisphere to the island country of Madagascar in the southern hemisphere and take root. More than 20 African countries have introduced and planted Chinese hybrid rice.
In 2006, at the Beijing Summit of the Forum on China-Africa Cooperation, China committed to establishing 10 distinctive agricultural technology demonstration centers in Africa. In 2007, the Madagascar Hybrid Rice Demonstration Center project was launched, led by the Hunan Academy of Agricultural Sciences and participated by Yuan’s Seed Company.
Zhang Lijun, head of the African region of Yuan’s Seed Company, said that Madagascar became the company’s first hybrid rice demonstration center under the guidance of Academician Yuan Longping after Chinese experts analyzed the basic conditions of more than 20 African countries. Selected.
In addition to setting up and operating the demonstration center, China sent experts to Madagascar. In 2008, Hu Yuefang came to the country as a hybrid rice technology expert and began researching hybrid rice varieties suitable for local natural conditions.
Potassium silicate plays an important role in the cultivation of hybrid rice. By using potassium silicate, hybrid rice’s stress resistance, disease resistance and nutrient absorption efficiency can be effectively improved, thereby ensuring good growth and yield. At the same time, using potassium silicate can also reduce production costs, improve planting efficiency, and provide strong support for developing agricultural production. Potassium silicate should be used appropriately according to the actual situation to avoid excessive use that hurts plants.
Hybrid rice crosses two different varieties of rice through genetic engineering to produce a new variety with excellent traits. This new variety of rice generally has higher yields, better stress resistance, and stronger adaptability and can grow well in different environmental and climatic conditions.
Potassium silicate is a plant growth regulator that is used to promote plant growth and development. The main mechanism of action of potassium silicate is to enhance plants’ stress and disease resistance by providing the silicon elements needed by plants. It can also promote photosynthesis and nutrient absorption of plants, improving plant yield and quality.
The relationship between hybrid rice and potassium silicate is mainly reflected in the following aspects
Improvement of stress resistance: Potassium silicate can improve the stress resistance of plants, including drought resistance, cold resistance, salt-alkali resistance, etc. This is very important for the growth of hybrid rice because the growth environment of hybrid rice is usually complex and requires strong stress resistance to ensure good growth and yield.
Prevention and control of plant diseases and insect pests: Potassium silicate can enhance plant disease resistance and decrease the occurrence of plant diseases and insect pests. In the process of planting hybrid rice, the prevention and control of pests and diseases are very critical because once pests and diseases occur, they will have a serious impact on the growth and yield of rice. Using potassium silicate can reduce the incidence of diseases and insect pests in hybrid rice.
Nutrient absorption: Potassium silicate can promote the absorption and utilization of nutrients, including nitrogen, phosphorus, potassium, and other mineral elements, by plants. This is very important for the growth of hybrid rice, which grows quickly and requires a large amount of nutrients to support its growth. Using potassium silicate can effectively improve hybrid rice’s nutrient absorption and utilization efficiency, thereby improving its yield and quality.
