You can take advantage of cement bags, sacks, pots, trays, foam boxes that are available indoors or empty plots in the garden to grow orange trees. Note: Perforated bottom of the tray for drainage. Planting tools are over 1m in size.
Orange is a light-loving tree and suitable for growing in areas with temperatures between 23 – 29 degrees C.
Land for planting
Orange trees can be grown in many types of soil from valleys, old alluvial soil, newly reclaimed hill land, alluvial soil and alluvial soil … The most suitable soil type is soil, much humus, good drainage, water level. underground under 1m. The arable layer is about 0.8 – 1m thick, the pH is 5 – 7.
Before planting, fertilize manure of decomposed animal manure, lime and dry it for 15-20 days before planting to treat pathogens in the soil.
2. Choose varieties and grow oranges
Currently on the market there are many varieties of saplings and you can choose varieties depending on conditions and preferences.
Oranges are usually propagated by seeds, branching or grafting. The kind of extraction of the branches will quickly turn left but the life expectancy is poor, the roots are weak. Grafted trees are healthier, longevity, healthy root development. Planting with seeds will take longer to produce fruit and productivity is often worse.
Seedlings you can find are available in the seed bar to save time and effort.
The most appropriate time for planting orangering oranges is at the end of the dry season at the beginning of the rainy season or at the end of the rainy season if conditions are available to irrigate.
When planting oranges oranges, holes of size 40 x 40 x 40cm or 60 x 60 x 60cm, high hills need to dig holes larger than 70 x 70 x 70cm. The distance of planting 4 x 5m oranges and oranges planted with a distance of 3 x 3m.
When planting, you use a hoe to dig a hole larger than a little bulb in the middle of the hole, put the seedlings in, use the foot to lightly compress the soil around the root, insert the stakes to fix the tree, avoid the wind to shake the roots, the plants are easy to die. If planting in dry season, after planting need to cover the roots with straw, dry grass to retain moisture.
After planting, immediately irrigate, then continue to water and keep the plants moist for 3 to 5 days during the first 1 month so that the plants can quickly root.
3. Take care
Need to provide enough water for the tree in the dry season, when the fruit is growing and the fruit is about to ripen.
To limit weeds, cover the roots with straw, dry grass, mulch, green manure to break the scum after heavy rains. Weeding the spring crop from January to February and the autumn season from August to September, clearing the entire area once per crop; a year of original cultivating 2-3 times.
After planting follow-up cut off the excess branches and buds growing from the rootstock. About 1-2 months when the tree has begun to root, sprout the tops in the afternoon of 70cm. Retain 7-10 healthy buds, evenly distribute stars around the root, avoiding obscuring light from each other. At the stage of mature trees, regularly remove old branches, pests and branches that have collapsed.
First year: After one month of anise, apply top dressing with diluted nitrogen fertilizer (1%), once every 15-20 days.
Phase 2 – 3: Each year apply 10kg of manure (micro organic fertilizer) + 100g urea + 300g super phosphate + 100g potassium divided into 4 times.
+ 1st time (September – November): 100% organic fertilizer + 100% super phosphate.
+ 2nd time (January – March): 40% urea + 40% potassium.
+ 3rd time (May): 30% urea + 30% potassium.
+ 4th time (July – August): 30% urea + 30% potassium.
Business stage (3rd year onwards) continues to keep the rate of fertilizer and number of fertilizer as above, but increase the amount of fertilizer for each year as follows: 30kg organic fertilizer + 500g super phosphate + 500g urea + 500g potassium.
Harvest when pods turn from green to yellow (about 20-30 areas of pods). Need to harvest at the right time to create plants to differentiate flower buds well, collect fruits on cool days.
Using scissors for cutting fruit stalks, collect fruits gently to avoid mechanical damage.
