The number of ears per mu is the decisionWheatOne of the important factors of yield, it refers to the total number of ears of wheat per acre, which can be directly reflectedWheatgrowth and yield levels. In order to improveWheatWe can promote it by increasing the amount of seeding, sowing seeds at the right time, and rational fertilizationWheatof multi-tillering, and then increase the number of ears per mu. However, we need to note that only effective tillering can form ears of wheat, while ineffective tillering cannot form ears of wheat and have a great impact on yield. Therefore, the reduction of ineffective tillering is improvedWheatAn important measure of yield.
Invalid tillering pairsWheatThe impact of production is mainly reflected in the following aspects. First of all, too much ineffective tillering can lead to:WheatThe growing space is crowded, affecting the distribution of nutrients and water, thus affectingWheatnormal growth and development, ultimately reducing yields. Secondly, ineffective tillering will makeWheatThe excessive density in the field affects the ventilation and lightness between wheat plants, reduces the formation of photosynthetic products, and further affects the increase of yield. Therefore, reducing ineffective tillering can be madeWheatThe growth environment is more superior and improvedWheatproduction levels.
1. Precise control of the sowing amount can provide sufficient nutrients for the growth of each wheat plant by reasonably controlling the sowing amount, and can also ensure the normal occurrence of tillering.
For high-yield wheat fields, the sowing amount per mu should be controlled at 22 25 catties, and for medium-yield wheat fields, it should be controlled at about 30 catties per mu. For varieties with strong tillering ability or wheat fields sown earlier, it is necessary to reduce the sowing amount appropriately to prevent too many ineffective tillering.
2. Sow seeds at the right time
Sowing at the right time is a guaranteeWheatImportant measures for the normal occurrence of tillering. By sowing at the right time, it can be promotedWheatBefore winter, tillering is normal and strong seedlings are formed, and the tillers before winter can become panicles, and there is basically no ineffective tillering. In general, winterWheatVarieties should be sown when the accumulated temperature reaches 700 800 degrees before winter, and the leaf age should reach about 7 leaves and 1 heart before winter, and there are 3 first-class tillers. Only by meeting these requirements can timely sowing be achieved in the field and the production of ineffective tillers can be reduced.
3. Control vigorous growth
In order to ensure that every tiller can be spikeped, we need to be inWheat3 Measures should be taken to control vigorous growth and reduce the production of ineffective tillers at the 5-leaf stage. Specific methods include: the use of chemical agents for peak control, sprayingPotassium monobasic phosphatewithPaclobutrazolTo control the wang long, the spraying time interval is 7 to 10 days;Upper growth is controlled by suppression or tillage of broken rhizomes, promotingWheatFormation of strong seedlings;For weak seedling plots, appropriate fertilizer should be supplemented to promote more tillering before the year and reduce the production of ineffective tillering after the year.
4. Promote polarization
InWheatAfter the tillering is stopped, all tillering beginsPolarization, some of the large tillers in the low position can develop into spikes, which belong to the effective tillering, while the small tillers in the high position gradually die and belong to the ineffective tillering. For the sake of accelerationPolarizationprocess, we can be inWheatCultivating and topdressing are carried out before getting up to jointing to speed up the development of tillers and use them at the same timeUreaCarry out top dressing, apply about 25 catties per mu. The tillage operation should be carried out before and after regreening, with an appropriate depth, usually around 5 cm.
By controlWheatIneffective tillering, can be effectively raisedWheatof production. In the actual planting process, we can control the vigorous growth and promotion by precisely controlling the amount of seeding, sowing at the right time, and controlling vigorous growthPolarizationand other measures to achieve the purpose of reducing ineffective tillering. These measures are both guaranteedWheatThe normal growth and development of the mu can effectively increase the number of ears per mu, thereby improvingWheattotal production.
In the actual planting process, growers also need to pay attention to observation and adjustment. By adjusting the sowing amount, fertilizer amount and fertilization time, etc., it can be adjusted according to the specific situation to adapt to the requirements of different varieties and growth environments, and minimize the occurrence of ineffective tillering. In addition,ScienceThe management and rational use of farmland resources are also improvingWheatAn important factor in yield. PassedScienceMeasures such as fertilization, crop rotation and recreation, and improvement of soil quality can optimize the soil environmentWheatThe growth provides better conditions for further improvementWheatof production.
To sum up, reduceWheatIneffective tillering is an important measure to improve yield. Through reasonable control of sowing amount, timely sowing, control of vigorous growth and promotionPolarizationand other measures can effectively reduce the production of ineffective tillers and improveWheatproduction levels. At the same time, growers also need to pay attention to observation and adjustment, and carry out planting management according to the specific situation to maximize the performanceWheatgrowth potential to achieve a bumper harvest.
