Culture method of balcony orchid

The sandy soil rich in humus and good drainage can be selected for the cultivation of Jian orchid on the balcony, the suitable temperature for growth is about 15-23 ℃, it can be cultured in a shady place in summer, appropriate light can be given in winter, watering can be carried out according to the soil conditions, yellowing and weak branches and leaves can be pruned in time, omethoate EC and carbendazim wettable powder can be used to control diseases and insect pests and propagate by means of ramets.

First, choose soil

The rhizome of Jianlan is relatively strong, which is suitable for breeding in sandy soil with rich humus and good drainage, as well as slightly acidic and iron-containing soil. The prepared soil is 40% humus soil and 40% burning soil.

2. Separate plant propagation

Jian orchid can choose a mud basin to cultivate. First, put the coarse plant material into the basin, fill it to 15% of the basin height, then select 1-2 clusters of plants, plant the plants in the middle of the basin, distribute the roots evenly during planting, avoid damage to the rhizome of Jian orchid, and then gradually fill in the fine plant material to 95% of the basin height, so that the orchid plant base is semi-exposed on the basin surface, and finally the soil can be gently compacted.

3. Suitable temperature

Jian Lan is a plant that is not tolerant to severe cold and high temperature. the growth temperature in winter should not be lower than 3 ℃, otherwise it will cause frost injury, and the growth temperature in summer should not be higher than 32 ℃, otherwise it will affect the healthy growth of plants. It is suitable for growing in places with an average annual temperature of 15-23 ℃. During the culture period, most varieties of Jian orchid can blossom twice in a year, or even 4 times in a year.

Fourth, reasonable lighting

Jianlan is a semi-negative plant, afraid of direct sunlight, it needs proper shade when entering summer, it can be shaded by 80% shading plastic, and it is necessary to maintain air circulation during the breeding period, and can sprinkle water around to lower the temperature. when entering the winter and spring season, it is necessary to give appropriate light to promote the growth of Jian orchid.

Fifth, timely watering

Watering according to the soil dry humidity, but should not be too much, the soil should be kept properly dry, into the summer and autumn, you can choose to water in the evening or in the morning, to ensure that the orchid leaves dry before nightfall, into winter and spring, watering can be carried out before and after sunrise, the amount of watering during the period should not be too large, which is helpful to restrain the occurrence of diseases.

VI. Thin application of fertilizer

According to the variety, seedling condition, physiological characteristics to fertilize, generally vigorous growth without disease can be fertilized, while weak growth does not need fertilization, leaves yellowing and thinning indicates lack of fertilizer, while black leaves and scorched leaf tips indicate excessive fertilization.

7. Pruning branches and leaves

In the process of cultivating orchids, the branches and leaves should be often pruned and the withered and yellow old leaves should be cut off in time, which is beneficial to plant ventilation, especially the leaves with diseases and insect pests, and should be pruned in time to avoid the spread of germs.

VIII. Control of diseases and insect pests

The common diseases and insect pests in Jianlan are anthracnose, black spot, shell insects and so on. The diseases can be controlled with 500x liquid 10% carbendazim wettable powder, while the pests can be controlled with 1500 times liquid 40% omethoate EC.
