摘要： A noninvasive method of source-sink regulation in rice belongs to the technical field of rice production. In this method, the source-sink relationship is regulated by a rice sterile line and its identical type of maintaining line being subjected to mixed-planting and insulated pollination, or sowing and transplanting at different times and insulated pollination, so as to construct rice plant samples with gradient difference of source-sink levels. The present invention is a kind of native, natural noninvasive method of source-sink regulation, which could broaden the traditional thinking of source-sink theoretical research, especially overcome the deficiency in conventional methods such as leaf-cutting, spikelet-thinning that lead to physical injury or physiological interference. The method provides a brand new approach and solution for thoroughly investigating source-sink relationship in rice, wheat, maize and other crops, and will play an important role in enriching crop source-sink theory and also promoting the development of the related disciplines.

摘要： The present invention provides a soil heavy metal curing agent for controlling accumulation of heavy metals of crops and its preparation method. The curing agent is made from the following parts of raw materials by weight: 60˜140 parts of substance containing carbon-carbon double bond; 1˜400 parts of sulfo-compound by sulfur; 50˜500 parts of organic matter by 10% water content; 0˜400 parts of water; 0˜100 parts of an initiator; 0˜200 parts of a reducer; and 0˜200 parts of a strong base. The curing agent for heavy metals in the soil according to the present invention can reduce the cadmium, lead and mercury content in the soil and further greatly reduce the roots' absorption of these heavy metals.

摘要： A organic fertilizer for controlling pollution or accumulation of heavy metal cadmium in rice and a preparation method and an application method thereof are related to the technical field of fertilizers. The fertilizer is, based on 100 kg of organic material with a water content of 15%, added with 0.05-5 kg of iron salt calculated as iron, and is also added with manganese salt, zinc salt and copper salt, wherein a mass ratio of the iron salt calculated as iron, the manganese salt calculated as manganese, the zinc salt calculated as zinc and the copper salt calculated as copper is 1:0.2-8:0.08-2:0.001-0.5.
