When to sow wheat?

On the issue of wheat sowing time, due to the different regions, there will be differences, the south and the north to see, the difference of half a month is a very normal phenomenon, some special areas, can be a month difference, so, from the time alone to analyze the time, probably in the following time period.

Generally, our country every year in March to April sowing spring wheat, 8 to November sowing winter wheat. But different regions have their own suitable sowing period. Winter wheat: September and October sowing, that is, between October 1 and October 23 for fall wheat sowing is the most appropriate. Every year in September and October is the peak of wheat sowing, but about the specific time of sowing, each wheat producing areas are still different.

The following April and May harvest (mainly south of the Great Wall) spring wheat: sown after the Spring Festival, harvested in August and September (mainly north of the Great Wall) winter wheat: winter wheat area in the middle and lower reaches of the Yangtze River, planting area accounted for 12.3% of the total output accounted for 45%. North China winter wheat area, is China's main winter wheat area, the sowing area of 47% of China, the total output of 53% of China. Spring wheat: Northeast spring wheat area, Heilongjiang, Jilin, low temperature, spring wheat is suitable. Northwest spring and winter wheat area, irrigation and loess plateau area.

Wheat to be high-yielding timely sowing is the key:

The timely sowing is to make full use of local light and heat and soil and water resources. It is an important technical measure to create a suitable starting point for the group, cultivate strong seedlings before winter, ensure the safety of seedlings over winter, build a reasonable group structure, prevent frost damage in winter and spring and late collapse and early failure, and lay the foundation for stable and high yield.

Wheat sowing time and temperature and variety characteristics of the closest relationship. Henan Province, the current promotion of wheat varieties are semi-winter or weak spring varieties, these two types of varieties of pre-winter formation of the main stem 5 ~ 6 leaves, single tiller 3 ~ 5, secondary roots 5 ~ 8 strong seedling standard of the appropriate cumulative temperature of 500 ~ 600 ° C. If the cumulative temperature of the pre-winter less than 400 ° C, will lead to insufficient tillers, small groups, secondary roots are poorly developed, the seedling situation weak; greater than 750 ° C is prone to cause pre-winter exuberant, and the winter is prone to frost damage, and the winter is prone to frost damage, and the winter is the first time that a variety of varieties are not available. winter and spring prone to frost damage, and for the late occurrence of collapse and early decline buried hidden trouble.

Districts in the specific determination of wheat sowing season, but also take into account the local wheat field fertility levels, soil moisture, topography and labor and the situation of the whole sowing machine to make appropriate adjustments. To be especially reminded that, because of the high temperatures this fall, and high temperature lasts a long time, autumn crop maturity harvest early, coupled with the province in late September, many precipitation process, the vast majority of areas of soil moisture is suitable, farmers must pay attention to do not grab moisture sowing, so as to avoid the pre-winter exuberant growth, winter and spring frost damage and late collapse, early failure to lay a hidden danger.

Be sure to seize the autumn crop harvesting early and recent good weather favorable opportunity to improve the quality of land preparation, scientific formula fertilization, strict control of the amount of sowing, mastering the appropriate depth of sowing, and vigorously promote pre-sowing or post-sowing suppression, and pay attention to the use of coated seeds or pharmaceutical seed mixing, for the current lack of moisture in the field of wheat but also in advance of the moisture watering to create moisture, to ensure that the moisture planting, and strive to improve the quality of sowing, for the normal growth and stable high yield of wheat. The first thing you need to do is to make sure that you have a good understanding of what you are doing and how you are going to do it.
