Guava is commonly known as Bale, remember in the movie "East into West" Liang Chaowei's classic scolding line "banana you bale", yes, Bala is guava.
Guava is native to the tropical regions of the Americas, belongs to the tropical fruit, until the 17th century was introduced to China, guava pulp is divided into red and white two kinds, red is mostly wild varieties, the flesh of the flesh is soft; white is mostly artificial cultivation, the taste is crisp. Because guava can hang fruit all year round, so the yield is high, and because of its low calories, it is a slimming health fruit for the three high people, so it has better planting benefits.
So in the cultivation of guava is prone to flower peel fruit, easy to fall fruit, hanging fruit situation, in the end what is the problem.
Guava belongs to the tree that constantly blossoms and hangs fruit, so some of the fruits on the tree are often ripe, and some only flower, generally from young fruit to maturity takes about 80 days. Generally about 3 years of trees, a year can produce 200-300, a quarter can produce 3-4 batches of fruit.
So what are the three magic weapons to solve the problem that guava is prone to flower peel fruits, easy to drop fruits, and few hanging fruits, and high yield and high quality?
Magic weapon one: reasonable pruning
First, the guava tree can not be too high, must be pressed short to control the height of the tree, in order to facilitate bagging, fruit picking, etc. The second is to control its tree shape, generally to maximize lighting and ventilation, natural happy shape is a commonly selected tree shape, like an umbrella. Third, guava is different from other fruits, because it produces fruit all year round, new branches germinate and grow faster, so every time a branch is cut, it will stimulate new shoots from other places to grow into branches, generally this new branch is easy to hang fruit. Therefore, through continuous pruning, cut off too high, too dense branches, stimulate the germination of new shoots, and then choose the right growth angle, which is conducive to growing into the required tree-shaped branches, and retain them as hanging fruit branches.
Magic weapon two: reasonable fertilizer water supply
General growers choose the compound fertilizer on the market to plant guava, so easy to cause soil compaction, unbalanced nutrients, usually using animal manure + compound fertilizer together fermentation to make organic fertilizer, animal manure is recommended to use cow and sheep manure, duck manure, try not to use chicken manure, especially fresh chicken manure, because it has too many germs.
Also because of the continuous fruit hanging of guava, then its consumption of nutrients in the soil is very large, the need for continuous replenishment, and to pay great attention to the protection of the soil, do not destroy the soil's aggregate structure, so the application of organic fertilizer to continuously help the soil recovery is essential.
The root system of guava is mainly horizontal roots, and the root system is shallow into the soil, and the fermented organic fertilizer can be directly sprinkled on the ground by fertilizing. In the later stage of fruit hanging, it is necessary to supplement fertilizer as appropriate according to the growth of the tree and the amount of fruit hanging, and fertilize a small amount of fertilizer many times. Water in time after fertilization and use water to immerse the fertilizer into the soil, so that guava can get nutritional supplements faster.
Then for moisture, in short, do not accumulate water at all, do not overly dry, and often keep the soil moist.
The third magic weapon: scientific bagging
Bagging is the best way to protect guava fruit from flowering skin, which is equivalent to putting on a protective coat for the fruit, which has a good protective effect on bird pests, insect pests and diseases.
Guava bagging is divided into two layers, the first layer is a foam mesh bag, it plays a role in isolating the second layer of plastic bags, protecting guava from burns, while protecting the epidermis from wind damage through the foam buffer, there are scratches; the second layer is a transparent plastic bag, in order to facilitate pan pomegranate lighting, the fruit it needs lighting to grow.
The time of bagging is generally to wait for the fruit to grow to 50 days, almost 2.5cm diameter when you can bagging, bagging too early fruit growth is not large, too late is prone to flower peel fruit.
The most important point is to carry out insecticidal sterilization work before bagging, to ensure that there are no germs and insect residues on the fruit when bagging. When bagging, to avoid contact between hands and fruits and bring in germs, usually open the mesh bag with both hands, let the fruit slip in by itself, and tighten the plastic bag on the second layer, pay attention to the tight mouth, do not enter the rain and insects.
