The sting has arrived! Wheat spring management is about to begin, and efficient management helps high yield
Today is a sting, after this day, it is the spring of wheat, how to raise, how to raise? Because wheat is different, the conditions are also different, so it is necessary to use appropriate methods for different regions and different conditions, and the following is the question of how to operate.
First of all, wheat can be divided into three types, namely: strong seedlings, secondary seedlings, yellow seedlings, weak seedlings, and late-sown seedlings. The first kind of wheat field (i.e., strong seedlings), soil moisture is large, watering can not be too early, must be postponed, otherwise too early topdressing at this time will not only lead to a drop in soil temperature, and then affect the growth, but also cause too much ineffective tillering, but also cause wheat to grow.
And what about the time of delay? Generally speaking, in the current situation, it is best to return to green, which is a very good time, because in the process of growth, the wheat will enter a polarization stage, and it is also a time when the demand for water and fertilizer is greatest, therefore, for this type of wheat, water and fertilizer should be postponed.
In addition, it is necessary to pay attention to the control of the growth of seedlings, in the early stage of Wang control, we have already said that physical control and chemical control can be used, that is, pressing and spraying Wang control agents. As for the best time to press and spray the anti-growth agent and the issues that need attention, you can refer to the previous article. All in all, no matter which method of controlling the growth is used, it should not be too early or too late, and the best time (i.e., from growth to early growth) should be grasped according to the actual situation.
Secondly, there are a large number of weeds in the farmland, which should be prevented in a timely manner after the temperature rises. In addition, when the ridge sealing period is about to enter, it is necessary to effectively prevent and control root diseases such as wheat sheath blight, root rot, stem base rot, etc., which is due to the fact that some diseases can be avoided, rather than **, and when it really appears, it is often too late.
In the process of prevention and control, we should pay attention to the prevention and control of pests in the wheat field, such as wheat spiders, etc., but also to add foliar fertilizers.
Then there is the second type of wheat seedlings, the third type of wheat seedlings, and the management of late-sown seedlings. If possible, furrow nitrogen fertilizer can be applied to accelerate the transformation of weak seedlings into strong seedlings. Even if you don't, you can take advantage of the gap between the three leaves and one leaf to spray the foliar once, which will also make the plant stronger, thus increasing the yield in the second year.
In addition, if weeds are found in the wheat field, it is necessary to wait until the wheat is strong before spraying, and safe herbicides should be used. In irrigation and fertilization, it can be earlier than a solar term for strong seedlings, and irrigation and fertilization can be carried out after the spring solar term, which is due to the promotion of late-sown wheat and the control of strong seedlings and strong seedlings as the focus, therefore, the management methods of different wheat are also different.
All in all, with the arrival of the stinging solar term, the temperature gradually rises, and the wheat has also entered the regreening stage, which is the most important stage for the number of ears and grains per hectare, so the management level at this time will directly affect the yield in the future, so it must not be taken lightly. However, it is necessary to manage wheat according to the type of wheat, and only by managing it properly can we obtain a better harvest.
