What to Do About Stunted Passion Fruit Seedlings? A Full Breakdown of the Latest Solutions
As a popular fruit in recent years, passion fruit has good market returns, and many regions have begun introducing and cultivating it. However, some growers have found stunted seedlings during the growing process, causing huge economic losses. So what should be done about stunted passion fruit seedlings? Let's take a look together.
1. Choose strong seedlings
The root system is relatively weak. If they are yellow clay soil seedlings, after transplanting into the field, if watering is not paid attention to, the soil is prone to hardening, the fibrous roots struggle to spread out, and stunted seedlings result. In addition, seedlings in non-woven bags with yellow clay substrate are difficult to degrade and will also constrain the root system. After diseased seedlings are planted, new leaves will also show mosaic and shrinking symptoms. Therefore, seedlings are very critical. It is recommended to choose virus-free passion fruit seedlings with well-developed roots and strong, robust plants, which will yield twice the result with half the effort.
2. Avoid damaging the roots
During the handling and planting of seedlings, damage to the root system caused by human, mechanical or other factors leads to a long recovery period after transplanting, which can also cause stunted seedlings. In addition, if planting is too deep, root extension will also be hindered, which can also lead to stunted seedlings. Generally, the soil covering height should preferably not exceed 1cm above the cup seedling soil. During transplanting, try to avoid root damage. After transplanting, check the seedlings promptly, and once stunted seedlings are found, replant them in time.
3. Use fertilizers and pesticides reasonably
To promote the slow recovery of seedlings and their subsequent growth and development, sufficient fertilizer is applied at transplanting. However, some farmers apply fertilizer too close to the roots, which easily causes seedling burn. Or when using herbicides, improper mixing of pesticides can easily produce phytotoxicity, causing bud tips to curl and even die. Therefore, when fertilizing, be careful not to let the roots directly contact the fertilizer, and herbicides must be used strictly and mixed reasonably according to the instructions.
4. Strengthen pest and disease control
Passion fruit is mostly transplanted in spring, which is exactly the season when pests and diseases are active. If root rot, Phytophthora and other problems occur, in mild cases they cause stunted seedlings, and in severe cases the plants wither and die. In addition, attention should also be paid to the control of underground pests, stem borers, thrips and other pests. This can be done in combination with land preparation and fertilization, nipping pests and diseases in the bud.
