How Does Wheat Spread Its Seeds? A Detailed Explanation of Wheat Seed Dispersal Methods
Wheat is one of the three major cereals and one of humanity's staple foods. After milling into flour, it can be used to make foods such as bread, steamed buns, biscuits and noodles, and after fermentation it can be made into beer, alcohol and baijiu. So, how does wheat spread its seeds?
1. How does wheat spread its seeds?
Wheat spreads its seeds by means of animals. Wheat seeds have awns, and the awns can hook onto animals' fur, letting the animals carry them to other places.
2. High-yield wheat cultivation techniques
1. Pay attention to choosing plots with high fertility and good water supply
High-yield, high-quality wheat varieties require soil nutrients to be comprehensive and sufficient in order to meet the needs of high-yield cultivation, so it is advisable to choose plots with high soil fertility and good irrigation conditions, to apply more organic fertilizer, and to adopt formula fertilization techniques.
2. Pay attention to sowing late at the appropriate time
According to the characteristics of the variety, determine the appropriate basic seedling number. Prevent excessive sowing rates, which would cause difficulties in later management.
3. Pay attention to preventing lodging, and apply heavy fertilizer at the jointing stage
Some of the promoted high-quality wheat varieties are not resistant to lodging. Especially for wheat fields with an excessively large population, a chemical control treatment must be carried out once from the greening stage to before jointing, and paclobutrazol or Maiyefeng can be sprayed. Apply heavy fertilizer at the jointing stage, control the formation of excess lower ears, and promote large ears with many grains.
4. Pay attention to watering well at the grain-filling stage and the wheat-yellowing stage
Watering well at the grain-filling stage plays an important role in increasing grain weight and preventing dry hot winds. In dry weather, using wheat-yellowing water is beneficial for interplanting the next crop and preventing premature aging. In early to mid-May, in combination with pest and disease control, spray 2 to 3 times with foliar fertilizer, such as 0.2% to 0.3% potassium dihydrogen phosphate, which can reduce the harm of dry hot winds and has an obvious yield-increasing effect.
5. Pay attention to pest and disease control
Generally speaking, high-quality wheat is more susceptible to pests and diseases, such as wheat sheath blight and powdery mildew, and aphids occur earlier and more severely than in conventional varieties. Early control should be carried out according to forecasts.
Spray Xiaomaibao once at around the time before wheat heading and flowering, to activate the activity of biological enzymes in wheat, promote coordinated development of female and male organs, enhance photosynthesis of functional leaves, increase the seed-setting rate and 1000-grain weight, and achieve a yield-increasing effect.
