Lessons to Remember After Losing Out by Not Applying Organic Fertilizer to Jujube Trees
This year, the selling prices of jujubes varied greatly. The price differences were mainly due to differences in sweetness and crispness, and apart from varietal characteristics, the main reason for the differences in sweetness and crispness was the different types of fertilizer applied. Currently, it is the second root development period for jujube trees. The first root growth peak occurs from late May to early June after new shoots stop growing, and the second root growth peak occurs from after fruit harvest to early November. From surveys of jujube growers, many farmers are only accustomed to fertilizing fruit trees in spring,

Detailed explanation of the specific operation techniques for flower and fruit thinning in pear trees
1. Master the timing of flower and fruit thinning. Flowering, fruit set, and the number of cells in young fruit are mostly determined by stored nutrients. Remove as many excess flowers and fruits as possible to reduce wasteful consumption and concentrate all nutrients on the flowers and fruits that should be retained, so they can grow into large fruits. Therefore, from this reasoning, earlier thinning is better: thinning flower buds is better than thinning flowers, and thinning flowers is better than thinning fruits. However, decide whether to thin buds, thin flowers, thin fruits, or combine all three according to the year's flower quantity, weather during the flowering period, tree vigor, fruit-setting ability, and other conditions. For pear orchards with a large flower quantity (an "on" year), good weather, and a heavy workload, you can

In which regions are Korean pine (Pinus koraiensis) tree species mainly distributed?
The distribution area of the Korean pine (Pinus koraiensis) tree species is: Korean pine is produced in the mountainous areas of Heilongjiang, Jilin and Liaoning in China at altitudes of 300 to 1800 m. Its natural distribution roughly coincides with the range extending from the Changbai Mountains and the Greater Khingan Mountains. It has been introduced and cultivated in Beijing and in such places in Shandong as Mount Tai, Mount Lao and Mount Kunlun. Korean pine has a fairly wide tolerance for light conditions, and as the tree age increases, its light requirement gradually rises. It most prefers deep, fertile mountain dark brown forest soil with good permeability. Korean pine is a shallow-rooted tree species, its taproot is not well developed, and its lateral roots spread very widely horizontally, which helps it absorb soil nutrients.

As spring warms and flowers bloom, insects begin to become active. During a recent science-and-technology outreach activity in the countryside, it was found that a pest called the box tree pyralid had begun to occur and cause damage on boxwood along the roadsides of the park. The box tree pyralid is one of the common pests on plants such as boxwood, small-leaved box, large-leaved box, littleleaf box, Chinese box, spoonleaf box, Korean box, and holly, and it occurs in Shanghai and other provinces and cities. In Shanghai it has 3 to 4 generations per year, with severe overlapping of generations. It usually becomes active in March in spring, begins pupating in mid-April, begins emerging in late April, and the first-generation lar

What are the control methods for bacterial shot hole disease in peach trees?
(1) Damage symptoms. Peach bacterial shot hole disease mainly damages peach leaves, and also infects twigs and fruit. After leaves are affected, nearly round or irregular brown lesions appear, and the lesions gradually dry up and fall off to form shot holes, hence the name shot hole disease. In severe cases, several lesions often join together to form large scorched patches, causing most of the leaf to dry up and resulting in early defoliation, so the disease is also called peach early defoliation disease. (2) Control methods. 1. Strengthen comprehensive management of the peach orchard. Apply more organic fertilizer, avoid

Technical measures for snow and freeze protection of mulberry trees, tea trees and fruit trees
I. Fruit: (1) Citrus: Before freezing, spray an anti-transpirant insulation agent on the tree canopy, and light smoke in the orchard to improve the freeze protection effect. For citrus affected by freezing injury, promptly remove curled, frost-killed leaves and withered shoot tips, bandage branches damaged by snow pressure, prune and shape branches broken by pressure, treat wounds with a wound protectant, promptly spray foliar fertilizer, and strengthen fertilizer and water management. For lightly frozen trees, apply 0.5% urea as a foliar topdressing 2-3 times; for severely frozen trees, it is advisable to apply light fertilizer multiple times in split applications. (2) Loquat: Insulate the tree disk by hilling soil or covering it with rice straw;
