According to incomplete records, there are about 50 fungus diseases of rice in *** blast and sheath blight are the most destructive and cause severe damage. Other fungus diseases, such as rot, narrow brown leaf spot, leaf scald and brown spot are not serious. Four bacterial diseases of rice occur in china. Bacterial blight is the most common and destructive one, followed by bacterial leaf streak, rice brown spot and brown *** latter two appear sporadically and are less important. The virus and virus-like diseases of rice that have been recorded in china are rice yellow dwarf, rice dwarf, rice yellow stunt, rice black-streaked dwarf, rice stripe, dwarf-like diseases, rice orange leaf disease, rice transitory yellowing, and grassy stunt etc. They are distributed mainly in the southern part of china beyond the Yangtze River. Rice yellow stunt virus has recently become important and widespread in china. It causes 20-30% of yield losses in areas where it prevails.

The mechanization of rice production in china has experienced a comparatively long and an undulating process. The full-scale making of mechanization of irrigated rice cropping regions was started at the mid 1960’s, later than that of upland cropping and its average level of mechanization operation also lower than the average level of the country. During this peiod, however, a series of mechines were created, which adapted to the characteristics of rice cropping regions in china, and the foundation was laid for the later paddy field machinery. For example, transplanting machine (created in 1956), boat—shaped tractors (1961), paddy field ploughing and harrowing serial (1974), and single wheel plowing machines (1979) etc.

Magnetizing seeds of crops has been a new agrophysical technique in recent years. The experiment of magnetized rice seeds by Seed-Magnetizer was conducted in Yuping Dongzu Autonomous County, Guizhou Province, china in 1991. The seeds of three rice varieties (Wenyou 3, Shuanggui and Teqing) were treated with SG-I *** passed through the Seed-Magnetizer with the passing rate 4000g / min for three separate times. The magnetic field gradient was 10t/m and the magnetic flux 6.5×10~4 t / m~2. And then, the magnetized seeds and non-magnetized seeds (CK) were simultaneously sowed on Apr 24, transplanted on
