How to apply Fertilizer in greenhouse Flower maintenance

Flower conservation in addition to watering, fertilization is also an important environment, flower conservation how to fertilize to make plants grow well, let's share below.

The fertilizer commonly used in flower maintenance is mainly organic fertilizer, which mainly includes human manure, barnyard manure, poultry manure, cattle and sheep horseshoe horseshoe, mule horseshoe, fish offal, oil residue, bone meal, compost and so on. But organic fertilizer must be fully fermented and ripened before it can be used. Of course, we can also use Flower Fertilizer tablets or urea, thiamine and other inorganic fertilizers. Other chemical fertilizers need to be diluted to 1-2 parts per thousand before they can be used as topdressing.

There are generally two ways to fertilize flowers and plants.

1. Base fertilizer

Base fertilizer is generally applied when changing pots in combination with flowers in flower maintenance. Generally speaking, the method of applying base fertilizer is to mix a certain proportion of mature organic fertilizer into flower culture soil. Bauhinia, horseshoe slices or dried dung can also be placed at the bottom of the basin soil.

two。 Topdressing

Generally speaking, the methods of topdressing during flower maintenance can be divided into two types:

(1) the first method of topdressing is to spread dung, oil residue and bone powder on the surface of the basin soil, and mix fertilizer and topsoil with wire hooks.

(2) the second method of topdressing is to soak the hoof slices, toenails, fish viscera and oil dregs with water, and then use them after fully fermenting, ripening and throwing water to dilute them. Topdressing flowers generally need to be analyzed according to the growth and development of flowers and plants and seasons, and dry fertilizer is generally applied in the growing period of flowers and plants, which can be carried out once a month. Topdressing liquid fertilizer is usually carried out during the peak growth period of flowers and plants, which can be done every 7-10 days.

When the weather is cool in autumn, it can be applied once every 15-20 days.

In winter, there is no need for topdressing except flowers during the growing period.

Fertilization is strictly prohibited during the dormant period of flowers and plants.

The principle of topdressing for flowers and plants is to apply more thin fertilizer, and liquid fertilizer that is not mature or too thick can not be used. Forced liquid fertilizer should be carried out when the basin soil is dry, watering can be controlled 1-2 days in advance, and the fertilizer can be concentrated when most of the flower pot soil is dry.

Southern flowers need to be fertilized with alum fertilizer and water. The preparation method is 1 part of black alum, 3 parts of pig manure, 5 parts of bean cake, 100 parts of mixed retting with water, fermented into a black liquid after one month, and diluted with water. Add enough water after each use until the color becomes lighter and then soak again.
