The latest cultivation methods of Banana in pots

Banana is strong, adaptable, likes sunny, warm and hot environmental conditions, but also more cold-resistant, lax requirements on the soil, can grow in all kinds of soil, but the soil layer is deep and fertile soil grows well. The suitable temperature for growth is higher than that of ordinary flowers, which is 25: 30 ℃. Below, the editor of Qiannong Network will introduce the cultivation method of banana pot.

It is suitable to choose dwarf varieties for potted canna. Generally, the proportion of rotten leaf soil, vegetable garden soil and rice chaff ash is 1.5-0.5, and a small amount of bean cake, bone meal and other fertilizers are added. From March to April in spring, the tubers were taken out, the decaying parts were removed, and the tubers with 2 or 3 strong buds were buried in the basin soil, and the bud tip was best exposed. Because canna is very fond of fertilizer and resistance to moisture, the basin should be watered thoroughly. When the fifth leaf grows to the fifth leaf, mature topdressing is applied every 7-10 days, and then watered after fertilization. Generally, 1% ferrous sulfate fertilizer and water is applied once a month, or a small amount of plant ash is added to make the stem straight and strong, the leaves green and thick, and the flowers bright. Stop fertilizing at the flowering stage. If you put it in a cooler place during flowering, you can prolong the flowering period. When the flower at the tip of the stem lags behind, the stem branches should be cut off from the base at any time in order to sprout new buds.

When potted canna is planted, the budding treatment in greenhouse can bloom earlier. During the operation, the old root should be covered with wet sand or loose peat soil from February to March, so that the rhizome should be covered properly and germinated at 16 ℃. When the buds on the rhizome germinate, cut the old stem into several pieces, each with more than one bud, planted in a flowerpot with a diameter of 10 cm and 12 cm, and change the pot again in April. According to the actual situation, a pot of 15 cm diameter can be used. It was moved to outdoor maintenance in the middle of May or planted in the open field, and it could blossom from July to August.

Potted canna sometimes shows scorched and yellowed leaves, mainly due to excessive application of ferrous sulfate or exposure to drought and hot sun. In the hot summer, if poured too cold water will also cause the leaf edge scorch, such as in the heat of summer fertilization is too thick, there will be cauterization of the rhizome to "burn". Therefore, when the temperature is more than 40 ℃, the canna can be moved to a cool and ventilated place. Before and after Frosts Descent, the potted canna can be moved to a temperature of 5: 10 ℃ to survive the winter safely, and fertilization should be stopped during the overwintering period.

Potted canna should pay attention to leaf curl pests from May to August every year so as not to damage its tender leaves and inflorescences. It can be sprayed with 1000 times of 50% dichlorvos or 50% EC of dichlorvos. There are occasional ground tigers in the banana, which can be caught manually or poured into the root soil with 600-800 times solution of trichlorfon.
