The Latest Tutorial on Fertilization Techniques for Star Fruit
Star fruit is an evergreen small tree of the wood sorrel family (Oxalidaceae) and a very typical tropical fruit. The star fruit is very unusual: cut it crosswise and it forms a five-pointed star shape. Star fruit has very high nutritional value and strong growth capacity, with high nutrient demands, so fertilization is essential in cultivation. So how exactly should star fruit be fertilized when growing it? Below, the editor brings you the fertilization techniques for star fruit. Let's take a look!
1. Apply sufficient base fertilizer
Base fertilizer is the key to ensuring robust early growth of star fruit, and it is generally applied into the planting hole when the fruit trees are newly planted. The base fertilizer is mainly decomposed farmyard manure, combined with an appropriate amount of superphosphate. Usually the amount of base fertilizer in each planting hole is kept at about 20 kg, with farmyard manure accounting for 80%. When applying the base fertilizer, it needs to be thoroughly mixed with the soil and then backfilled. When backfilling, be careful to keep it about 20 cm above the ground to prevent water accumulation from affecting the growth of star fruit seedlings. Base fertilizer needs to be applied after harvest every year, in order to ensure flowering and fruiting of the star fruit trees the following year.
2. Topdress at the right time
Topdressing for star fruit is mainly determined by various factors such as the age of the star fruit tree and the amount of fruit it bears. For example, during the young tree stage, the nutrient absorption capacity is not strong, but a certain amount of nutrients is needed, so during the young tree stage, the main approach is to apply more frequently in small amounts. Topdressing is needed once every year until before November, and when the growth rate of the star fruit tree gradually declines, stop applying nitrogen fertilizer. Then at the winter solstice, apply decomposed farmyard manure in a hole for each tree to strengthen the vigor and cold resistance of the star fruit tree. Pay attention to the amount; do not apply too much, as excessive application can easily cause fertilizer burn, leading to pests and diseases and affecting the growth of star fruit.
3. Winter fertilizer
The main application of winter fertilizer is very important, because after harvest, most of the nutrients in the fruit tree leave with the fruit, resulting in nutrient deficiency in the fruit tree and a decline in tree vigor; moreover, winter temperatures are low, which is very unfavorable to the growth of star fruit trees. Therefore, applying winter fertilizer well can restore the vigor of star fruit as quickly as possible, reduce the harm of low winter temperatures, and improve the cold resistance of star fruit. To prepare for the next year's growth, the fertilizer is mainly organic fertilizer, and the amount applied should be determined according to the size of the tree, its growth vigor and the amount of fruit borne.
4. Fertilizer to promote shoots
The fertilizer to promote shoots is mainly applied around April each year when the spring shoots of the star fruit tree sprout, and the fertilizer is mainly nitrogen fertilizer. The purpose is to promote the sprouting of spring shoots, ensure robust growth, and increase the amount of flowering. Then in summer, topdressing should be done about twice more, which can play a role in protecting flowers and fruit for some star fruit trees that bear fruit more than twice. However, in the south, it is in the rainy season, and fertilizer is easily washed away by rain, so it should be applied in stages. At the same time, pay attention to controlling the amount well to prevent fertilizer burn and increase cultivation costs.
The above is a brief introduction to star fruit fertilization techniques. Fertilization work for star fruit is very important. Because star fruit has a large fertilizer requirement, if nutrients are insufficient, the flowering and fruiting amount of star fruit will drop sharply, affecting planting benefits.
