Question 2: How to fertilize potted grapes? What fertilizer is better for applying all-element compound fertilizer? It is best to spray potassium dihydrogen phosphate on the leaves often, which can promote the flowering and fruiting of plants. Grapes like light, so it is better to put them in a bright and ventilated place on the balcony. Just dry them and pour them thoroughly. Dry them without watering, for fear of waterlogging.
Question 3: When should potted grapes be fertilized? Fertilization time:
1) Nitrogen fertilizer should be applied 1 2 times in the early stage of germination to promote the vigorous growth of branches and leaves and facilitate flowering;
2) Before flowering, apply 1 ~ 2 times of thin fertilizer mainly containing phosphorus and potassium;
3) When the flowers wither and set fruit, dry cake water should be applied every 7 days ~ 10 to make the fruit swell. In order to reduce the evaporation of odor, dry cake water should be applied in furrow. First, dig a 2 cm to 3 cm ditch around the basin edge, put the cake fertilizer water into the ditch, and immediately cover the soil, so that the fertilizer will change from light to thick. You can also spread the decomposed cake powder on the surface of the pot soil, let it ripen again in the pot, and mix it evenly with the soil after 7 days to 10.
Matters needing attention in fertilization:
The fertilization principle of potted grapes is to apply less frequently.
1. Generally, potted plants that have not yet borne fruit start from the height of about 20cm (that is, 6-7 leaves) and apply 1 time cake fertilizer every 7- 10 days until the end of September.
2. In order to ensure the requirements of fruit development, it is best to apply potted grapes 1 time every 5 days. After the fruit is harvested, it should be applied according to the pot seedlings. Pay attention to watering immediately after applying liquid fertilizer every time.
3. Foliar spraying can also be carried out.
(1) In the early growth stage of potted grapes, 0. 1%-0.3% urea solution can be sprayed 2-3 times;
(2) From the fruit swelling stage, 0.3% potassium dihydrogen phosphate solution can be sprayed 3-4 times every 7- 10 day.
Question 4: Potted grapes. I don't know how to fertilize grapes Before flowering, we need to promote the growth of roots. The special water-soluble fertilizer for Fujinmen can be used to promote rooting and improve the flowering and fruit-setting rate, the high nitrogen and high potassium water-soluble fertilizer can be used to protect flowers and fruits, and the special water-soluble fertilizer for expanded fruits can be used to promote root growth and improve the quality and yield of grapes during the fruit expansion period.
Question 5: Do potted vines need fertilization? Just go to the flower shop to buy compound fertilizer and bury 20 pieces in a pot. The amount should not be too much, which will cause fat loss.
Question 6: Is it difficult to cultivate potted grapes? What fertilizer should be used? Potted grapes need a bigger pot, but it is not necessary to bury animal carcasses in the soil. It is best to use other organic fertilizers instead. When animal carcasses are decomposed and fermented, the smell is too bad and the pollution is particularly heavy.
Generally speaking, chicken manure, pig manure and cow dung are suitable as organic fertilizers. When these fertilizers are not available, sesame sauce residue (sesame oil residue) or bean cake can be selected instead, and the effect is equally good.
If there are many rotten leaves in the basin, it can be directly mixed with river sand, and then topdressing can be done during the growth of grapes.

Question 7: Fertilize potted vines. What I bought was the use of compound fertilizer. How much to fertilize flowers at a time should be timely and appropriate, and at the same time, we should grasp the season and time. Generally speaking, fertilization is carried out during the growth period of flowers, and flowers that grow vigorously need more fertilizer; Apply total nutrient fertilizer at seedling stage, mainly phosphate fertilizer at flowering and fruiting stage, mainly nitrogen fertilizer at foliage flower stage, and stop applying fertilizer at dormancy flower stage. In addition, we should also master the principle of "thin and fat application", that is, "eat less and eat more meals" It is best to apply thin fertilizer every 10 day during the growth period of flower seedlings, and the best effect is to apply fertilizer at night. Avoid applying fertilizer around noon, because high soil temperature is easy to damage the root system. Organic fertilizer must be fully decomposed before it can be applied. The fertilizer efficiency of controlled release fertilizer developed in recent years can reach half a year or even longer, and its one-time application amount can be greater than that of water-soluble fertilizer, and the gradual release of nutrients can meet the long-term nutrient demand of flowers. There are two ways to fertilize flowers, base fertilizer and topdressing. Base fertilizer refers to the fertilizer applied to the soil before planting flower seedlings. When planting flowers in the open field, first mix the base fertilizer into the soil, and then cover the soil to raise seedlings. Indoor potted flowers, you can put base fertilizer at the bottom of the pot soil, such as bean cake, fish bone powder and so on. Pay attention to the fact that the root system cannot directly contact the fertilizer. Some flower production enterprises have begun to use controlled release fertilizer as base fertilizer. Topdressing refers to topdressing in the growing season of flower seedlings. For flowers in the open field, dry fertilizer can be applied around the seedlings and then watered, or directly irrigated with fertilizer. Potted flowers can be sprinkled with dry fertilizer powder on the surface of the pot soil, and then loosened and watered. Soaking liquid such as bean cake, sesame sauce residue, horseshoe slice and ox horn. Used for topdressing, fermented and made into fertilizer water for application. Fat water is suitable for large potted flowers in flower beds or open air. Flowers in strongly acidic soil in South China, such as camellia, rhododendron, gardenia, Michelia, Milan, jasmine, etc. Adding 0. 1% ferrous sulfate to the soaked fertilizer water can make alum fertilizer water. It can also be used as topdressing after various fertilizers are mixed and extruded. Or spray 0. 1% fertilizer solution (1 two fertilizers plus 100 kg water) on the aboveground part of the flower seedlings to make the leaves of the flower seedlings dark green and shiny, and at the same time prevent the flowers from falling and falling.
Question 8: Do potted grapes need fertilization? If yes, what fertilizer should be applied, which is good and how? Grapes like fertilizer, but it is difficult to bear fruit without adequate fertilization. Even if some grapes bear fruit, it is easy to lift the base and fall off. During the growing period, dilute liquid fertilizer was applied every 10 day, and nitrogen fertilizer was the main fertilizer during the growth of stems and leaves, and phosphorus and potassium fertilizer were the main fertilizer before flowering and after fruit setting.
Question 9: Who can tell me what fertilizer to use for potted grapes? Before Qingming, some old roots can be pruned, new culture soil can be added and base fertilizer can be applied at the same time. The base fertilizer can be bean cake, eggshell, crab shell, bone meal, etc. Top dressing once every 0/0 day after new buds germinate. After bean cakes, fish heads, fish intestines and other sprouts grow, each liquid fertilizer is decomposed and applied. Don't apply too much fertilizer, but be sure to water it after application. The principle of fertilization is "applying thin fertilizer frequently". In May, more nitrogen fertilizer was applied during flowering and leaf opening. After June, nitrogen, phosphorus and potassium fertilizer were mainly applied, and after July and September, potassium fertilizer could be applied.
Question 10: Grape grafted seedlings can be fertilized a few days after planting, and can only be fertilized 15 days after germination. At this time, the injured root system can be completely recovered and has absorption ability.
