Key points of mango cultivation techniques in the year of planting mango

This variety was introduced from Thailand in 1990 and was selected from its excellent asexual breeding population for several years. After four consecutive years of multi-point planting experiments in Guangdong, Guangxi, Yunnan and other places from 1996 to 1999, the genetic characteristics of the excellent characters were stable, with the following characteristics:

First, it can blossom and bear fruit all the year round

The first plant blossomed from late February to late March and ripened from late June to late July; the second plant blossomed in late April and ripened in late July; the third plant blossomed from late July to early August and the fruit matured in late November; the fourth plant blossomed in late September and ripened in March-April of the following year.

Second, the flowering period can be adjusted artificially, and the off-season fruit is very strong.

The flowering of mango in four seasons does not need low temperature. under natural conditions, it can be adjusted to blossom and bear fruit in any season as long as it is cultivated by cultivation techniques (such as pruning, shaping, spraying or spraying growth regulators).

Third, rough birth is easy to grow, but the result is early.

Like other mango varieties, four seasons mango has fast growth rate and can obtain yield through extensive management. when grafted seedlings are planted in spring of that year, they can blossom and bear fruit in autumn.

Fourth, strong resistance and wide adaptability

The four seasons mango is resistant to stem rot, anthracnose and angular spot. As long as fruit bagging is implemented, more than 90% of the high-quality commercial fruits can be obtained. The drought tolerance is stronger, and the cold resistance is stronger than Zihuaomang. Flowering at 35 degrees Celsius, it can still blossom and set fruit, and it lasts about 80 days from Xiehua to fruit ripening. Where ordinary mango trees can live, they are suitable for planting mangoes in the four seasons.

5. High yield and high yield performance

The average annual yield of mango is more than 3 kg in the second year, 15 kg in the third year and 30 kg in the fourth year. It is one of the highest mango varieties in China.

The appearance of the fruit is beautiful and the quality is excellent

The appearance of the four seasons mango fruit is beautiful, and the single fruit weighs 200-300 grams. The flesh is thick, golden, less fiber, the edible rate is 76-83%, the soluble solid content is 20-24%, and the kernel is thin and slender. More than 60% of mature fruits after September show no nucleolus. The quality is better than the world famous brand mango-Lu Song Mang.

Due to the strong off-season fruiting characteristics and easy artificial adjustment of the yield period, this variety can obtain better economic benefits, so it is worth popularizing the planted varieties.

Key points of cultivation techniques:

The main results are as follows: 1. Choose loose soil and fertile land for planting: because of the large amount of mango fruit in the four seasons, more times and faster growth rate, there are more fertilizer and water than other varieties. As long as the tree is strong, high-yield and high-quality fruit can be obtained.

2. Prevent young and big trees from blooming sporadically and promote exuberant vegetative growth. Spray gibberellin + 0.3% 0.5% urea solution once a month in the season when flowers and fruits are not needed. (note: the dosage of gibberellin is 50-80ppm in summer and autumn and 100-150ppm in winter and spring).

3. Artificial florescence regulation method: from April to October every year, about 50 days before the selected flowering date, when the new shoots are ripe, spray 15% paclobutrazol (300g / 100jin water) + 300ppm ethephon (ethephon content is 40%) + 0.5% potassium dihydrogen phosphate (preferably potassium nitrate) about 30 days after application.

4. Apply the fertilizer of promoting flower and strengthening flower: (when the flower ear is 5 cm, spray 400 times cytokinin + Lvwang 2 (high nitrogen), at the same time, apply 1-2 rotten water fertilizer and add 0.5% multi-component compound fertilizer.

5. Bagging: after the fruit thinning, the fungicide pesticide is sprayed, and then the fruit is bagged. Use bluish blue plastic sand bags in summer, non-woven bags in winter or wax-treated paper bags all year round.

6. pest control: the pest of mango in the four seasons is relatively small, mainly to prevent diseases.

(1) pay attention to the control of mango heart borer at the beginning of each heading, and it is found that the insect can spray 20% permethrin 2000-3000 times, 40% Lesbon 1000 times or 40% omethoate 800 times.

(2) the main diseases of mango are anthracnose, bacterial angular spot and downy mildew. In the prevention and control of diseases in fruit protection work throughout the year, the key is before flowering and after fruit setting, the medication procedure is as follows: after spraying 1-2 times with Spock or methyl topiramate or methomyl, and then spraying Bordeaux solution or 77% cupric oxychloride.
