Wheat field suffers from snow after rain
2023-03-17 04:06:55
On November 6, the winter wheat growing area in Hebei province generally welcomed a rain and snow weather. Although this rain and snow increased the water holding capacity of the wheat field, improved the soil moisture in the wheat field, eased the drought situation in the current wheat field, and created favorable conditions for the safe wintering of winter wheat, but the rain and snow earlier than in previous years, It was 4 days earlier than the sudden drop in snowfall in 2009, which inevitably affected some wheat fields.
To achieve high yields of wheat, it is necessary to cultivate strong seedlings with well-developed root systems at the seedling stage to lay a sound foundation for the creation of a reasonable high-yield group in the coming year. At present, most of the wheat is in the period of 2 to 3 leaves. This is the critical period when the nutrients in the seeds are consumed and the wheat roots are unable to absorb water and fertilizer, and the worst resistance during the lifetime (commonly known as the weaning period). If the cold wave is attacked at this time, a lighter degree will postpone the wheat tillering period, affecting the effective ear of the wheat field in the coming year, heavy wheat seedlings will suffer from various degrees of frost damage, and the dry tip leaves will wither, which will seriously cause the death of the aboveground parts. occur. The severity of the impact is closely related to wheat seedlings.
1. A class of strong seedlings should be cleared and suppressed promptly after the weather is warm. The current type of seedlings is in the three-leaf stage of wheat, and the three-leaf wheat will begin to deliver with the accumulation of nutrients. That is, people commonly known as the "full moon" produce secondary roots on the base of the stem, also known as Divide the roots. It is also a critical period for obtaining effective panicles and creating high-yielding populations for wheat next year.
At this time, the ploughing can effectively increase the ground temperature by 3 to 5°C, prompting the wheat to start delivery earlier, and prevent the cold wave (wind and snow) from coming into contact with cold injury to lay a good foundation. The cracking of the wheat fields can break up the soil, consolidate the soil, make up for cracks, and prevent the snow and wind from freezing and damaging the roots of the wheat seedlings caused by surface cracking.
2. After the weather in the second and third crops is warmer, you can use 5 ml of Dodge + 40 g of potassium dihydrogen phosphate or 30 ml of shamrock + 15 g of Boron Boron or 3 grams of BiGuard to spray a bucket of water. , Interval 5 to 7 days, continuous 2 or 3 times better.
3. Straw returned to the wheat field in time to suppress the wheat field. And when the temperature is warmer after the crackdown, use 5 ml love to receive more + 40 grams of potassium dihydrogen phosphate or 30 ml backing more than + 15 grams of Phosphorus to spray a bucket of water, interval 5 to 7 days, continuous 2 ~ 3 It is better to avoid cold injury.
4. Post-emergence weeding in wheat field Immediately after entering the autumn crop of weeds in the wheat field, we will control the periods of wheat, brome, aegis, and broadleaf weeds. Due to the low temperature and dry and rainy weather after sowing wheat this year, the thin root system of wheat seedling leaves is underdeveloped, and the overall adverse resistance is poor. In addition, the rain and snow have just been subjected to the surprise attack. If the autumnal weeds occur at this time, It is tantamount to "increasing the severity of the problem" and has a serious impact on the delivery of wheat. Therefore, it is recommended that the prevention and treatment period should be postponed until the weather turns warmer and wait for an opportunity to spray pesticides. If the spraying agent is added with an appropriate amount of mitigating phytotoxicity regulator or foliar fertilizer, it will be very good to avoid yellowing or seedling emergence of wheat seedlings. In addition, the wheat crops will return to early morning without premature aging, and the grains will be full, which will lay a good foundation for high yields in the coming year. Foundation.
