Latest: Reasons Why Chestnut Trees Only Bloom but Do Not Bear Fruit and Preventive Measures

Chestnut is a fairly common fruit tree, and many farmers grow it in their own yards, but during cultivation, chestnut trees often show the phenomenon of only blooming without bearing fruit, which gives farmers a big headache. So what should be done about the phenomenon of chestnut trees only blooming but not bearing fruit? Let's take a look together.

1. Reasons Why Chestnut Trees Only Bloom but Do Not Bear Fruit

There are many reasons why chestnut trees only bloom but do not bear fruit. First, it is caused by a poor variety. There are many chestnut varieties; just as there are good varieties, there are also poor ones, and some varieties bear fruit with relative difficulty. Second, the soil is not suitable for planting. Chestnut prefers slightly acidic soil with a pH below 7; for example, gneiss sandy soil with good permeability is more suitable. If the soil is on the alkaline side, it will cause the tree not to bear fruit. Third, soil drought and lack of water cause hardening, which can also lead to no fruit. Fourth, the chestnut plant has insufficient nutrients: large trees have many male flowers, and female flowers set no solid fruit; small trees have many male flowers but no female flowers.

2. Preventive Measures

1. Skillful fertilization

Chestnut's demand for fertilizer differs from that of other fruit trees. Mature fruiting trees should be given more fertilizer such as boron, manganese and calcium. In spring before flowering, 300-400 grams of urea plus 200-300 grams of calcium fertilizer can be applied per tree, and 6-7 grams of boron fertilizer can be spread per sq m. During the fruit enlargement stage, sufficient fruit-strengthening fertilizer should be applied, and 07-1 kg of ternary compound fertilizer can be applied per tree. After harvesting the fruit, combined with deep digging and hole expansion, heavy winter fertilizer should be applied, with 40-50 kg of farmyard manure and 1.5 kg of calcium magnesium phosphate fertilizer per tree. In addition, spraying a mixed solution of low-concentration borax, urea and monopotassium phosphate once every 10 days can significantly increase the fruit-setting rate.

2. Skillful pruning

Chestnut likes light, so the tree's ventilation and light transmission must be ensured, and vigorously growing extension branches and dense, weak branches should be thinned out in time. In spring, according to flower quantity and flower quality, shoot control and shoot removal should be done well to promote the sprouting of secondary shoots. For secondary shoots, generally 2-3 shoots are kept per branch. For branches that are too long or have a small angle, methods such as branch bending and branch hanging can be used to encourage the branch angle to open and flower bud differentiation, balancing vegetative growth and reproductive growth.

3. Skillful fruit preservation

Chestnut is a fruit tree that is pollinated by different flowers on the same plant, so more than 2 varieties should be configured in the orchard to facilitate pollination. If the variety is single, artificial pollination can be used to preserve fruit. After the chestnut sets fruit, fruit thinning should be done in time to improve the commodity rate of the fruit and maintain tree vigor, and the amount of fruit kept per branch should be kept balanced.

4. Skillful pest and disease control

Common pests and diseases of chestnut include anthracnose, clearwing moth, longhorn beetle, peach fruit borer and scale insects. To maintain high yield, timely spraying of highly effective, low-toxicity, low-residue pesticides should be carried out for control.
