Scientific management holds up the brand Nanguo pear

1. Through winter and spring pruning, fruit trees are pruned to create an umbrella-shaped crown, which is ventilated and transparent. Pay special attention to summer shearing (summer shearing), remove all the overgrown branches, upper back branches and new branches of adult fruit trees, reduce the waste of nutrients in the tree body, maintain the moderate state of the crown, and make all the nutrients produced by leaves effectively used for fruit growth and tree development.

two。 Farm manure is the most ideal fertilizer to improve fruit quality because of its complete nutrients. Bao Dianhong's orchard applies farm manure once every two years, with 200 kilograms of fully mature farm manure per tree, plus some chemical fertilizer every year. He believes that this can not only ensure the health of the tree, but also control the overgrowth of the tree and cause six shades in the crown, ensure the coloring of the fruit and improve the quality of the fruit.

3. Artificial pollination and rare fruit artificial pollination are effective measures to improve the fruit setting rate, and it is better to use Xuehua pear, Yali pear and white pear pollen. He advocates that each inflorescence (usually 5-7 flowers per inflorescence) should be artificially pollinated and sit on the fruit. In order to improve the speed of pollination, he used a special breeding gadget developed by himself, which could pollinate all the flowers of the inflorescence at once. In the case of sparse fruit, one of the best fruit is selected for each inflorescence, and the rest are all removed, which is one of the important measures to improve the quality of fruit.

4. The prevention and control of diseases and insect pests in Nanguo pear orchard mainly include pear heart borer, peach heart borer, pear wood lice, yellow powder aphid, scab, powdery mildew and so on. He observed the orchard every day, and once he found the situation of diseases and insect pests, he sprayed the medicine in time. The concentration of the pesticide should be appropriate, not the higher the concentration, the better, and the spraying should be uniform. Under the tree, outside the tree, and on both sides of the leaves must be sprayed: the orchard can solve the problem of diseases and insect pests by spraying only 4 or 5 times a year.

5. The abalone Dianhong does not advocate shoveling the weeds in the tree plate. On the contrary, let the tree plate be covered with grass. When the grass grows to 20-30 cm high, it will turn over the soil to fertilize the field. At the same time, the grass in the tree plate is conducive to the breeding of the enemy and plays a role in biological control of diseases and insect pests.

6. Artificial leaf picking to promote the coloring of Nanguo pear Bao Dianhong once accidentally found that almost all the leaves had fallen on the branch of Nanguo pear, but the fruit was red. So he carried out a leaf-picking experiment in the second year, and the effect was quite good. In the 10-15 days before harvest, concentrated efforts will prevent Nanguo pear from being exposed to light, that is, all the leaves in the range of 10-15 cm around the fruit will be removed, so that the fruit will be fully exposed to sunlight. After 4-15 days, all the Nanguo pears on the tree are all colored, he believes, one more colored Nanguo pear, one more income.

In the autumn of 2006, Professor Guo of Shenyang Agricultural University came to Yingbu Village to conduct a training course on artificial leaf picking to promote coloring techniques. Bao Dianhong realized that manual leaf picking not only promoted the coloring of Nanguo pear, improved its appearance quality and commodity value, but also significantly improved the quality of Nanguo pear, greatly increased sugar content, reduced fruit acidity, and increased the content of anthocyanin and vitamin C. it can be said to kill two birds with one stone. In 2007, all 200 Nanguo pear trees in Bao Dianhong's orchard were treated with leaf removal. The red fruit rate was 84%, the yellow fruit rate was 9%, and the green fruit rate was 7%. The leaf picking and coloring of Nanguo pears sold 2 yuan more per kilogram than those without treatment. His family produces 10,000 kilograms of Nanguo pears every year, which can increase the benefit by 20,000 yuan.

7. In 2006, he started the fruit sticker experiment. Before the fruit was colored, he pasted some auspicious words such as "Kung Xi Facai", "all the best" and "Happiness and longevity", which further improved the commodity value of the product.
