The booting stage is a key period for gaining the multiple kernel weight of wheat. In this stage, sufficient water and fertilizer supply should be provided to ensure flower growth and accumulate more nutrients, which has a good effect on preventing premature leaf senescence and improving the filling strength. Field management is mainly to maintain roots and protect leaves, extend the green time of the upper leaves, prevent premature aging or greed, keep flowers and increase grains, promote filling, and strive for full grain weight. Management should pay attention to the following points:
1. Water in time. Wheat needs a lot of water in the late growth period. This period is in the dry season, with less rainfall and more dry and hot winds. In order to ensure the normal and firm filling of wheat, the areas with conditions after heading should be watered with earing, popping, and grouting to meet the water requirement of wheat.
2. Prevent lodging. First of all, it is necessary to combine reasonable selection of anti-lodging varieties for close planting, deep ploughing and improve the quality of site preparation, promote root development before winter and greening, and adjust the group structure. Especially in the period of getting up and jointing, it is necessary to accurately judge the seedling condition, and rationally use fertilizer and water and chemical regulation. In addition, during the grouting period, pay close attention to the weather to prevent lodging caused by watering in windy days.
3. Top root fertilizer. After the flowering of wheat, the initial spraying of phosphorus fertilizer twice, the 1000-grain weight can increase 2 to 3 grams, an increase of about 10%, because the late spraying of phosphorus is helpful to increase the effective phosphorus and sugar content in wheat stems and leaves, can promote the filling, make the 1000-grain weight Increase, the maturity period advances. If the wheat leaves are yellow-green after flowering, there will be signs of premature aging, which can be combined with spraying phosphorus and spraying urea at a concentration of 1% to 2% (avoid excessive concentration).
4. Remove weeds in wheat fields in time. It is not advisable to carry out chemical weeding after the wheat is jointed. It is necessary to seize the time and manually remove it to prevent subsequent troubles caused by seeding.

Double Packed Yellow Waxy Corn Cob
The most common waxy and sweet corn market, waxy corn nutrient content is higher than ordinary corn, contains 70-75% starch (and almost all amylose), more than 10% protein, 4-5% fat and 2% multivitamin, has more grain, VA, VB1, VB2 than rice protein, fat and VB2 highest content. Yellow corn also contains carotenoids like rice and wheat. The molecular weight of glutinous corn starch is more than 10 times smaller than that of ordinary corn. The starch makes glutinous rice sticky and soft, which is softer than that of ordinary hard corn. It has more than 20 percent more digestibility than regular corn and is suitable for people with irregular teeth. At the same time, the amylose (a polysaccharide) content is very high, not suitable for diabetics.
Waxy corn is also called sticky corn. The grain has a coarse, waxy endosperm that resembles a glossy, transparent grain, such as a hard, dented corn. Its chemical and physical properties are controlled by a recessive gene located on chromosome 9. 100% of the starch in the endosperm is amylose.
