The tree length developed well and uniformly through the data collection times.
The tree develops to the 35th leaf (when the tree has fruited for 2 weeks), then proceed to cut the buds to develop fruit.
Supplement the tree periodically.
Plants begin to flower when they are 30 days old.
The net house control system helps to support timely watering and nutrition for plants with the following values:<\/p>\n\n\n\n- Soil moisture over 70%.<\/li>
- EC concentration 12.<\/li><\/ul>\n\n\n\n
The temperature should not exceed 45 degrees Celsius.<\/p>\n\n\n\n
- The amount of water for plants increased gradually over the weeks from 200ml to 700ml on day 30.<\/li><\/ul>\n\n\n\n

\u2013 The average number of female flowers of the plant is 10 flowers (calculating the female flowers from leaves 7 to 17):<\/p>\n\n\n\n- The best female flowers are from flowers 9 to 13.<\/li>
- The tree continues to produce female flowers after the 17th leaf, but the flowers are small at this time and the ability to set fruit and raise fruit is not high.<\/li>
- Due to growing in a net house, it is necessary to pollinate the plants.<\/li><\/ul>\n\n\n\n
After 1 week of flowering, the tree begins to bear young fruit.<\/p>\n\n\n\n

\u2013 Prune leaves around the left, cut the top at the 35th leaf.<\/p>\n\n\n\n
\u2013 During the fruit care period, it is necessary to add potassium with the ratio of nitrogen: phosphorus: potassium is 1: 1: 2 and gradually increase to 1: 0: 3 when the fruit begins to create a net around the left.<\/p>\n\n\n\n
\u2013 Hang the fruit on the rope when the fruit is heavy compared to the strength of the tree.<\/p>\n\n\n\n

Through the experiment, the research team noted a number of suggestions such as the need to take measures to prevent flooding of the net house due to heavy rain to avoid waterlogging of the plants. One point to note is that in the stormy season, high winds will easily cause the tree to fall, causing the tree to overturn and break the roots, affecting the growth of the tree.<\/p>\n\n\n\n
