Rape weak seedlings turn strong measures
During the winter of rapeseed during the winter, drought and freezing are superimposed (the temperature is below 0°C for about 40 days). Under this rare climate condition, the development of rapeseed is inhibited, and freezing injury is widespread and very serious. According to the province's statistics for the planting station in March, the province's area of ​​rape damage was 3.998 million mu, an increase of 1.514 million mu over the same period of last year, accounting for 66.7%, an increase of 27.5 percentage points over the same period of last year. At present, the number of green leaves of rape is less, the growth is weak, and the imbalance is large. Some plants are short, stems are fine, and early flowers are grown. Due to the combination of long-term drought, low temperature, and frost damage during the winter and this spring, the main stems of weak seedlings, young seedlings, and tall seedlings that were planted in late sowing were dead or prevented. The rain and snow before and after the Spring Festival restored the growth of undead seedlings in the underground. Some of the seedlings germinate new shoots from the root of the neck. After the application of fertilizers and temperature rises, “old seedlings†and tufted plants are formed. The seedbed should be left as required. Pay attention to thin uniform seeding, cultivate large seedlings, uniform seedlings, strong seedlings, and improve the ability of plants to respond to disasters. The production potential of rapeseed varieties such as Shilifeng and Shilijia for large-scale production has great potential. The timely application of Linhua fertilizer in the field of fertilizer shortage can increase the number of effective branches and grain weight, and make up for the loss of seedlings and missing trees.
