Pear trees do not result

To avoid partial nitrogen fertilization, some rural households use pear trees to plant sweet potatoes. In order to cut the potatoes and vines to raise pigs, pig manure is often poured into the fields, causing the pear trees to grow tall and large. To stop pig manure in this situation and increase the application of phosphorus and potassium fertilizer, potassium dihydrogen phosphate solution can be sprayed on the canopy drip and canopy.

Excluding waterlogging pear trees are planted in the fields. Although the soil is deep, the soil is fertile and the pears grow well, the drainage is poor. In the flowering period, there is usually too much rain. Because of the waterlogging, the growth of the pear tree is frustrated, so that there is very little fruit or even fruit. It is necessary to open a drainage ditch for this situation so that it can be filled with drought and it will not rain on rainy days.

Proper pruning branches and some pears grow too vigorously. Cut down the main branch and some of the branches. Pull the long branches into the canopy at the edge of the canopy. This can not only control the vegetative growth, but also increase the light-receiving area and light intensity, which is beneficial to the results.

The pollination tree planted with pollinated tree seedlings was cultivated. The fruit set rate within pollination was very low, even without fruit set. The increase of pollination varieties can promote the pollination results of pear trees. The ratio of pollen tree and original planting tree is 1:3.

Artificial-assisted pollination Selection of varieties with strong affinity and large amounts of pollen as pollination varieties, collection of mature anthers that are about to crack or have just cracked, drying in the sun, padding newspapers, cracking the anthers, collecting pollen, and then artificial pollination.

Spraying plant growth regulators to spray plant growth regulators at the flowering stage can increase the fruit setting rate; spraying the plant growth regulators during the expansion period of young fruit can reduce fruit drop, promote fruit weight, improve quality and increase yield. The types of plant growth regulators include 920, protopine, and Penshibao.

By taking an organic farming and processing approach, the main characteristics of organic foods come from organic farming systems that are eco-friendly. Organic food production and processing, do not use chemical pesticides, chemical fertilizers, chemical preservatives and other synthetic substances, and genetically engineered organisms and their products, therefore, (organic food) is a truly from the nature, nutrition, high quality and Safe and environment-friendly (ecological food), Xihuangcao active ingredient Xihuangrouxin A, Mei-Mei A, has anti-cancer activity, has a significant inhibitory effect on human cervical cancer cells
