Cultivation methods and precautions of lemon flower: too strong sunlight and poor growth

Lemon blossom in summer, with mosquito repellent effect. It's very fragrant. If you put a pot of lemon flowers at home, you don't need to use air fresheners. The flowers of lemon flower are white and beautiful, which are deeply loved by everyone. So how is lemon flower cultivated? What good method is there in breeding? What matters should we pay attention to when breeding lemon flower? Please read down with me with your questions!

White lemon flower culture methods (basic knowledge): the best breeding time: cutting time is best in the rainy season, or in May, June rainy days.

The best growth soil: potted Lu soil should be made into permeable, water and fertilizer retaining, slightly acidic culture soil.

Growth humidity requirements: Lemon needs more water in the growth and development, too much water is not easy to rot root. In summer and autumn, water should be sufficient, but not too much, otherwise it will easily lead to flower and fruit drop.

The best growth temperature: the annual average temperature is above 15 ℃, the best growth temperature is from 23 ℃ to 29 ℃, stop growing above 35 ℃, and freeze injury occurs at - 2 ℃. Lemon generally does not need to cool down in summer. It can enter the room before frost and leave the room after Tomb Sweeping Day.

The best growth light: lemon is a light loving plant, but if the sunlight is too strong, it will grow poorly. Generally, the plants need to be placed in a mild environment suitable for growth at noon.

Notes on the cultivation of lemonade seedlings: fertilizer application: Lemonade prefers fertilizer. In addition to applying enough base fertilizer in pots and changing pots, the principle of thin fertilizer and frequent application should be adhered to in the growing period. The frequency and amount of fertilization should be determined according to the growth trend and phenological period. If liquid fertilizer is applied, the cake fertilizer water with full fermentation is better, and the ratio of cake to water is 1:200. The northern soil is alkaline, so ferrous sulfate can be added to the fertilizer solution to form a slightly acidic nutrient solution.

Key points of watering: in order to prevent excessive growth of summer shoots, accumulate nutrients and promote the formation of flower buds, water the potted lemon before summer.

Pruning tips: before spring shoots germinate, it is necessary to carry out intensive pruning, first remove dead branches, diseased branches, overgrown branches, inward branches, Cross branches, sprouting branches, etc. If the strong branch is cut weakly, 4 or 5 full buds will be left; if the weak branch is cut strongly, 2 or 3 buds will be left, so that each branch will have more robust spring shoots. In order to control the excessive length of the spring shoots, the 3 and 4 segments of the shoots can be cut off. In order to induce more summer shoots, the new shoots will be pinched when they have 6-8 nodes.

The pot culture pot must be changed during the cultivation process. The best time to turn the pot is half a month before lemon sprouting. Before turning over the basin, prepare a basin that is as big as the original one. Take it out of the basin. Don't break the mud. Cut off 1 or 2 cm thick topsoil along the mud. Cut off the dead roots and rotten roots. Cut off 1 cm thick soil at the bottom of the mud. Take out the tiles that fall into the soil. The drain hole of the new basin is laid with tiles. First, a layer of 2 or 3 cm thick drain layer is paved, and then a layer of 4 or 5 cm thick nutrient rich culture soil is paved, which is mixed with a small amount of superphosphate. Then put the lemon mud into the basin, fill the culture soil around to the mouth of the basin, slightly compact the basin soil, pour enough root setting water, place it in a ventilated and semi shady place, and put it back to the original place after a week for daily management.

Breeding points:

1. Cutting propagation: take annual strong branches, about 15-20cm long, the lower end should be flat. Cut off most of the leaves on the branches, leaving only 2 or 3 leaves at the top, and insert them into the sandy soil with good drainage. The soil should be disinfected in advance, not fertilized. Insert half the length of the branch. Pour enough water and put it in the underworld to keep the basin soil moist, but not ponding. After about 40 days, the branches will germinate.

2. Grafting propagation: take the strong root of Rough Lemon (a hybrid of lemon) as the rootstock.

Pest control: the common pests and diseases of lemon flower are coal pollution, scale insects, aphids, red spiders, etc., which can be controlled by relevant drugs. In northern China, due to the alkalinity of water, jarosite (ferrous sulfate) can be added during fertilization to adjust pH value and avoid physiological etiolation.

The experience of potted culture of lemon flower: the specific method of water deduction for lemon flower is that the water supply to potted lemon gradually decreases in more than ten days before summer; the water supply is stopped in the first five days, and the soil in the pot is dried due to a large amount of evaporation after being exposed to the sun; the root system loses water due to lack of water, resulting in withered and curled leaves. In order to prevent dehydration of leaves, water can be sprayed to the leaves early and late, and a small amount of water can also be sprayed to the basin soil.
