Spring farming has been carried out in the northeast of China. The Ministry of Agriculture (MOA) held a meeting recently in Harbin, the capital city of Heilongjiang Province, promoting the technology for raising rice seedlings in plastic sheds. It is learned from the meeting that the areas planted with japonica rice in Heilongjiang, Jilin and Liaoning provinces are expected to increase this year, in view of good weather conditions, an early start of farming, a solid job and the great initiative of farmers. In addition, thanks to the promotion of the technology, the pace of seedling-raising in the northeast of China has witnessed a notable increase over last year. For example, by April 18, 2011, 86 percent of seedlings have been raised in Heilongjiang Province, up 22 percent year on year; in Jilin Province, the job of seedling-raising has been finished four to five days earlier than the previous year; and the performance in Liaoning is almost the same as last year.
The meeting holds that the breakthrough in the technology for rice cultivation has made a significant contribution to the current production of japonica rice. The breakthrough is demonstrated in three aspects: a. the breakthrough in the planting method by growing strong rice seedlings in dry nursery; b. the breakthrough in the seedling-raising method by adopting sparse planting; and c. the breakthrough in the method for increasing production by planned cultivation. The breakthrough in the technology for raising seedlings of japonica rice in plastic sheds in the northeast of China has moved up the nursery date by 7-20 days and gained 100-150℃ of accumulated temperature. As a result, local growers have successfully resolved the contradiction between the short frost-free period and low accumulated temperature in the northeast of China, especially the arctic-alpine areas of Heilongjiang Province, and the long growth period of fine-quality, high-yield rice; headed off late spring coldness, low temperature, chilly weather and early injurious frost, thus laying a solid foundation for the high yield of fine-quality rice.
The three provinces in the northeast of China have laid down principles and measures to accelerate the application of the technology for raising seedlings in plastic sheds. With their efforts, it is expected that across the three provinces, the number of plastic sheds used for raising seedlings will mount to 920,000; the total area of these sheds will increase to 660, 000 mu (about 44,000 ha); and the transplantable area will reach 54.02 million mu (about 3.6 million ha), an increase of 190,000, 160,000 mu (about 11, 000 ha) and 12.05 million mu (about 0.8 million ha) respectively over 2010.
