The critical period of nutrition refers to the fact that the absolute amount of fertilizer nutrient requirements for wheat is not large, but the period of need is very urgent. If such nutrients are lacking at this time, the growth and development of the crop will be significantly affected, and the resulting loss will be difficult to recover or make up even if it is applied later. Phosphorus critical period of nutrients in wheat seedling stage, because the root system is still very weak, poor absorption capacity, so the need for phosphorus at the seedling stage is very urgent. The critical period of nitrogen nutrition is when vegetative growth turns to reproductive growth, and winter wheat is during the two stages of tillering and spikelet differentiation. The application of nitrogen fertilizer in the late growth stage can only increase the nitrogen content in the stems and leaves, and it has no obvious effect on increasing the number of grains per spike or increasing the yield.
The term “maximum nutrient efficiency†refers to the period when wheat has the most absolute nutrients, the fastest absorption rate, and the highest fertility yield. The maximum nutrient efficiency of winter wheat is from jointing to heading, at which time it grows vigorously and its ability to absorb nutrients is strong. Fertilizers need to be topdressed in a timely manner to meet the greatest demand for nutrients from wheat and to obtain the best fertilization results.
Fruit and vegetable powder also means fruit and vegetable juice powder. The making method is about first crush the fruit and vegetable to juice, then vacuum concentrate it, and then use high temperature to spray it to powder. Do not add any flavors and artificial colors. To a great extend retain the nutrition, color and flavor of plants and fruits.
