The late stage of wheat growth refers to the stage from heading to maturity, and it is also the period in which the economic output (grain) of wheat is formed, and it is the most critical and most important period in wheat management. During this period, the water and nutrient supply of wheat fields have a direct impact on yield formation. Therefore, it is necessary to effectively regulate water and fertilizer to meet the physiological needs of wheat for normal development.
Special attention should be paid to prevent two extreme phenomena: one is defertilization (premature attenuation due to malnutrition), and the other is greed (because of overnutrition often leads to prosperous growth and late ripening and dryness).

Special attention should be paid to prevent two extreme phenomena: one is defertilization (premature attenuation due to malnutrition), and the other is greed (because of overnutrition often leads to prosperous growth and late ripening and dryness).
Later management should focus on "rooting, leaf protection, grain preservation, and weight gain". Booting to heading is the critical period for wheat to require water throughout its life. If the wheat is affected by drought in this period, the yield will be severely reduced. Therefore, it is required that the soil moisture in the wheat field in this period should be suitable. At the same time, the application of fertilizers should be cautious. According to the conditions of the wheat seedlings, spray fertilizers on the outer roots and leaves. For wheat fields with normal seedling conditions, potassium dihydrogen phosphate should be added to increase the intensity and rate of grouting, increase grain and weight and increase yield. For wheat fields with signs of defertilization (yellow leaves, small and weak population growth, and red spider hazards), urea, amino acids, and micro-fertilizers should be added to promote greening, greening, and delaying aging.
For wheat fields that grow too vigorously and tend to grow greedy and green (the leaves are black and green, the population is too large and dense), it should prevent falling, disease, and late maturity, strictly control watering, and prohibit the use of *** fertilizers. Avoid droughts and watering, and do not spray nitrogen-containing foliar fertilizers, and only spray relevant pesticides to prevent diseases and insects in the later stage. Generally, spraying fertilizer can be combined with the prevention and control of plant diseases and insect pests, making overall planning and comprehensive utilization, and implementing "one spray and three prevention" from the booting stage to the filling stage. It can be used per acre with 150 grams of potassium dihydrogen phosphate (fertilizer), 20 ml of 1.8% abamectin EC (for insect control), 40 ml of 20% triadimefon EC (for disease prevention), and 5 grams of 0.1% 481 brassinolide (to promote growth) ), spray with 50 kg of water, spray 2-3 times in an interval of 7-10 days. However, it is necessary to adjust the increase or decrease of pesticides and fertilizers according to the conditions of wheat field seedlings, diseases and insects, to ensure the actual effect of preventing diseases and pests, reducing disasters and increasing production.

Professional aging products are based on "knowing the old and understanding the old". The design of aging products should meet the real needs of the elderly, facilitate the care needs of nursing staff, and adapt to the home-based elderly care environment.
The characteristics of the elderly are aging of the lumbar spine, discomfort of the cervical spine, osteoporosis, and fatigue. Therefore, it is particularly important for the elderly to protect the waist and neck to delay the aging rate and reduce the incidence of diseases and accidents.
First, the backrest of the Chair is large and strong, and it is equipped with armrests, so that the waist of the old man is close to the back of the chair and can support the head and shoulders of the old man.
Second, the height of the chair should be at the same level as the knee, that is, when the old man is sitting, his feet can be placed flat on the ground. At the same time, the length of the chair seat should be the same as the length of the old man's hip to knee, so that the knee joint can be maintained at about 90 degrees, and the ankle joint can be in a natural drooping rest state.
Third, the chair should have some weight, and 3-4 kg is the best. If it is too light, it is difficult to maintain certain stability and easy to slip. The chair material should not be too soft.
