When will the wheat be planted? What's wrong with uneven seedlings?

Wheat is a common grain crop in China, which is planted in almost every region, but it is mostly in the north and is one of the main food rations in the north. When will the wheat be planted? What's wrong with uneven seedlings?

When will the wheat be planted?

1. The planting time of spring wheat is from March to April in Northeast China.

2. Winter wheat planting time: the planting time of winter wheat in North China is usually around November.

As the northeast of China is not yet winter, there will be a thick layer of snow, the temperature is very low, not suitable for the growth of wheat, so generally no longer planted in winter. On the other hand, the climate in North China is relatively stable throughout the year, and multiple rotation can be carried out, so it happens that other crops are sown in winter after the autumn harvest to prevent the land from being abandoned.

Second, what happened to the uneven wheat seedlings?

First, improper storage of seeds: before harvesting wheat, it must be carried out at noon on a sunny day, and the harvested wheat must be dried and finally put in a dry and ventilated place. If it is not properly preserved, the plumpness of the seeds will be reduced, thus reducing the germination rate. In daily life, many farmers like to mix new and old seeds, but this is not good, and it is most likely to lead to uneven emergence.

Second, the land is poor: wheat likes to grow in an environment with deep soil and strong ability to store water and preserve fertilizer. if the soil water spreads quickly or the soil is too loose, it will make it difficult for seeds to emerge, and the seedlings will naturally be uneven.

The third reason is insufficient nutrition: when wheat grows in plots where there is no base fertilizer or less base fertilizer, it will grow poorly due to lack of nutrition. in addition, if there is unrotten organic fertilizer in the base fertilizer, or fertilization is too low, there will also be the phenomenon of burning seedlings and seed injury.

Fourth, weather reasons: wheat seed germination and seedling unearthed have certain requirements on soil temperature and humidity. If the sowing time is too late and the temperature is low, it will reduce the seedling emergence rate and prolong the seedling emergence time. If the soil is dry during sowing, or if the clay is hardened by heavy rain, it will also affect seedling emergence.

Reason 5. Diseases and insect pests: without coating or chemical dressing before sowing seeds, they are easily harmed by underground pests such as grubs, ground tigers, golden needles, mole crickets and so on, resulting in lack of seedlings and broken ridges. In addition, wheat sowing too late, in the low temperature and high humidity environment is very easy to be infected by bacteria and dead seedlings, or the use of herbicides drug residues will also affect the normal emergence of seedlings.

Remedial measures for uneven emergence of wheat:

1, and time seedling replenishment: after the emergence of wheat seedlings, check the field situation in time, pull out dead and withered seedlings in time, and transplant seedlings in time where there are no seedlings or grow too dense, so as to ensure that the seedlings are complete.

2. Timely ploughing and loosening soil: during the growing period of wheat, the soil should be cultivated according to the soil consolidation, and the surrounding weeds should be removed in time, so as to improve the soil permeability and promote the growth of seedlings.

3. Do a good job in the prevention and control of diseases and insect pests: during the planting period, it is necessary to do a good job in the management of water, fertilizer, weeding and other management work to prevent the occurrence of diseases and insect pests.

The above is the introduction of wheat planting time and the reasons for uneven emergence and remedial measures. I hope it will be helpful to you.
