1. Leafy vegetables: refers to vegetables that use the tender leaves and petioles of plants as edible parts, mainly cabbage, green cabbage, spinach, amaranth, etc. Features: The planting density is relatively large, most of which are shallow-rooted vegetables, so the demand for quick-acting nutrients in the soil is more sensitive and urgent. If nutrients are not supplied in time, the leaves will turn yellow and the growth rate will slow down. Fertilization skills: The base fertilizer is mainly organic fertilizer, and the top dressing is mainly quick-acting nitrogen fertilizer, combined with phosphorus and potassium fertilizers, and other element fertilizers should be properly applied. The base fertilizer application should be sufficient, and the top dressing should be reasonable: the slow-acting fertilizer should be added in the early and mid-growth period, and the accelerating-acting ammonium bicarbonate should be applied in the late growth period. During the period of vigorous growth of vegetables, nitrogen fertilizer should be mainly applied, and appropriate amounts of phosphorus and potassium fertilizers should be added. 2. Fruit vegetables: refer to vegetables that have a long growth period and will bloom and bear fruit. The reproductive organs of the plant are used as the edible part of the vegetables, mainly melons, solanace fruits and beans. Features: The vegetative growth period and the reproductive growth period of fruit vegetables are carried out at the same time, the growth time is long, and the demand for the three major elements is large. Fertilization skills: Seedlings need a lot of nitrogen fertilizer, but excessive application of nitrogen fertilizer can easily cause excessive growth, prolong flowering and fruiting, and cause flower and fruit drop. During the reproductive growth period, the demand for phosphate fertilizers increased greatly, but the demand for nitrogen fertilizers decreased, so it is necessary to increase the application of phosphorus and potassium fertilizers and reduce the amount of nitrogen fertilizers. The base fertilizer and top dressing required for the growth of fruit vegetables are very important. Enough base fertilizer should be applied and top dressing should be made as early as possible. After the fruit is harvested, quick-acting nitrogen fertilizer should be applied immediately to promote the next wave of fruit growth. 3. Root vegetables: refers to vegetables that use plant roots or tubers as the edible part, mainly radishes, carrots, and vines. Features: After root vegetables enter the vigorous period, the leaves will gradually stop growing. Fertilization skills: Organic fertilizers should be used as the main fertilizer, and chemical fertilizers should be used with phosphorus and potassium fertilizers, combined with nitrogen, phosphorus and potassium; more nitrogen fertilizer should be applied in the early stage of vegetable growth, and potassium should be increased in the middle and late stages of growth, but the amount of nitrogen fertilizer should be reduced; fertilization should be controlled during flowering. Avoid flowers, fruit and leaves; topdressing should be done in time during the young fruit period and harvest period to promote fruit expansion; high-concentration fertilizers are strictly forbidden, and topdressing is forbidden when the soil is wet. Concentrated fertilization is strictly prohibited. Disclaimer: Some articles on this website are transferred from the Internet.

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.
