Leafy vegetables Leafy vegetables refer to vegetables that use the tender leaves and leaf stalks of plants as edible parts, mainly cabbage, green cabbage, spinach, amaranth and so on.
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: organic fertilizer is mainly used for base fertilizer, quick-acting nitrogen fertilizer is mainly used for top dressing, and phosphorus and potassium fertilizers are used in combination. At the same time, other elemental fertilizers should also 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 added in an appropriate amount 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.
Fruit vegetables Fruit vegetables refer to vegetables that have a relatively long growth period, bloom and bear fruit, and use the reproductive organs of the plant as the edible part. They mainly include 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 require a lot of nitrogen fertilizer, but excessive application of nitrogen fertilizer can easily cause excessive growth, prolong flowering and fruiting, and cause falling flowers and fruit. 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.
Root vegetables Root vegetables refer to vegetables that use plant roots or tubers as the edible part, mainly radishes, carrots, and vines.
Features: After the root vegetables enter the vigorous period, the leaves will gradually stop growing.
Fertilization skills: organic fertilizers should be used as the main application, chemical fertilizers should be used with phosphorus and potassium fertilizers, combined with nitrogen, phosphorus and potassium; more nitrogen fertilizers should be applied in the early stage of vegetable growth, and potassium fertilizers should be increased in the middle and late stages of growth, but the amount of nitrogen fertilizer should be reduced; Control fertilization to avoid falling flowers, fruit and leaves; topdressing should be done in time during the young fruit period and harvesting period to promote fruit expansion; high-concentration fertilizers are strictly forbidden, and topdressing is forbidden when the soil is moist. Concentrated fertilization is strictly prohibited.
