Do you know the misunderstanding of winter wheat sowing?

There are many misunderstandings in the winter wheat sowing process. Do you know the misunderstanding of winter wheat sowing? Share it with you today.

Winter wheat also reached the time of concentrated sowing after the autumn season. According to previous years of planting experience, many wheat farmers do not pay attention to details when planting, it is easy to enter the misunderstanding of winter wheat sowing, affecting the emergence of winter wheat.

1 variety selection

It is very important to choose a variety. Sowing spring and weak winter varieties in the middle and early sorghum plots will cause the wheat seedlings to grow long before winter, which is not conducive to safe wintering. On the basis of early drafting and suppression, the roots of the soil should be engulfed before winter, or “Mengtou manure” should be applied to protect the wheat seedlings from wintering safely.

2 sowing too early

If the wheat is planted too early, the leaves will be long and narrow, and the leaves will be draped, and the tillers will be insufficient. The main stems and some of the large stalks will enter the two-edge period before the winter spikes. When the temperature is low at -10 °C in winter, freezing damage will occur. . Therefore, when planting, timely suppression should be carried out to inhibit the growth of the main stem and the big scorpion; after the pressing, timely slashing, combined with watering, apply 15 kg of ammonium per acre, if necessary, use 0.2% ~ 0.3% chlormequat solution leaves Spray to control the length of the child and resist frost damage.

3 sowing late

Due to the short growth period before winter and insufficient accumulated temperature, the growth of wheat seedlings is weak and there are few tillers. Therefore, the wheat farmers should focus on simmering and replenishing water, and apply 10~15 kg of ammonium per acre during the three-leaf period; the wheat field with poor soil moisture and fast water seepage, and timely pouring water after the three-leaf period. I would like to remind the wheat farmers that if the plot is suitable or the soil is heavy and the water seepage is poor, it is not suitable to water before winter.

4 sowing too shallow

The sowing depth of wheat is 3~5 cm, the seeding is too shallow, the wheat seedlings grow, the minced joints are bare, the tillers are many and small, and they are susceptible to freezing and premature aging. It is recommended that the wheat farmers should suppress the wheat several times before the emergence of the seedlings. After the emergence of the seedlings, the roots of the soil can be combined with the soil. If necessary, the soil can be covered or covered with the "small heads" during the wintering period to prevent wintering and freezing.

5 sowed too deep

If the wheat is planted more than 5 cm, it is too deep. If the seeding is too deep, the wheat will be slowly emerged, the leaves will be slender, the tillers will be small and small, the secondary roots will be weak and weak, and the wheat seedlings will be thin. The wheat farmers should carry out the clearing of the soil in time, start with the bamboo raft or the shovel from the center of the glutinous rice noodles, and traverse the ridges and ridges. When the last line is cleared, the remaining soil can be dragged onto the back of the raft. Remind everyone, McDonald's friends, for the wheat that is planted in a timely manner, the clearing of the trees before winter generally starts from the second leaf stage and ends when it comes to "small snow".
