Lemon flower protection and new measures

Lemon is one of the coldest species in citrus and is suitable for warmer winters, less hot summers and cooler temperatures.

In order to make lemon more flowering and more fruitful, it must be scientifically managed in water, fertilizer, pruning, etc., in order to increase the fruit setting rate and commodity value of lemon.

First, fertilizer and water management technology

After germination of spring buds, 0.2% zinc sulfate is applied first, and before flowering, young fruit, and fruit expansion, “melon and fruit sedum” +0.4% to 0.5% urea+0.2% to 0.3% of dihydrogen phosphate Potassium sprays together. After the young fruit is stable, it is necessary to keep the soil water abundant. The key is to drench the water once in the early 10 days before the spring. When the fruit is ripe yellow, stop fertilizing and reduce watering, so that the soil remains moist and slightly dry. If you continue to give too much fertilizer, the fruit will mature and fall early.

Second, control the summer shoot

During fruit growth, if the fertilizer is sufficient, the nutrition status of the plant is good, and some shoots will sprout new shoots. The growth of new shoots will inevitably divert some of the nutrients and affect the growth of the fruits, which is not conducive to flower bud differentiation. In order to keep the fruits, the new shoots should be promptly erased and trimmed. Trim wounds with "wound anti-corrosion film" in a timely manner smear sterilization.

Third, Baohuabaoguo

Lemon has prosperous characteristics, and the result tree can be controlled and prolonged by methods such as cutting off roots, controlling water, and cutting branches. During the flowering period from May to June, the circumcision technique was used. The blunt blade was used to cut deep into the xylem at the smooth part of the trunk, and afterwards, the “Huawang 2” was applied to protect the fruit and control the summer shoots.

Fourth, spray boron fertilizer

For boron-deficient orchards, 0.1% to 0.2% borax can be sprayed during the flower bud differentiation period, and then sprayed again after the flower is cut to increase the fruit rate and fruit quality.

Through the new measures for the preservation of fruits and fruits in the lemon tree, it is ensured that the nutrients in the flower and fruit period are sufficient, and nutrients are concentrated to provide stable production and high yield.
