Control Methods and Technical Key Points for the Jujube Mealybug on Jujube Trees
(1) Manual and physical control. Bark scraping: During winter and early spring, scrape off the old coarse bark on the trunk, branches and forks and burn it in a centralized manner; spray the whole tree with 3-5 degrees Baume lime sulfur mixture, or apply a sticky insect glue ring about 1-2 cm wide on the main trunk and branches, to prevent the insects from climbing up the tree and from moving from concentrated overwintering branches to non-concentrated overwintering branches to cause damage, and to trap and kill some of the pests. (2) Chemical control. The application time should be chosen during the peak hatching period of the newly hatched nymphs, generally from late May to early June, early to mid-July, and early September.

What are the key technical points for post-harvest management of jujube trees?
1. Apply fruit-harvest fertilizer well. Apply fruit-harvest fertilizer once 3-4 days before harvest or 5-7 days after harvest. Generally apply 50-60 kg of organic fertilizer per jujube tree, applying it by the trenching method at the base of the main trunk of the jujube tree, and cover with soil immediately after application. 2. Spray quick-acting fertilizer. Immediately after harvest, spray 0.3-0.4% urea solution and 0.4%-0.5% potassium dihydrogen phosphate solution on the leaves to avoid leaf drop, improve photosynthetic efficiency after harvest, accumulate and increase tree nutrients, promote more flower bud differentiation, and reduce

Introduction to the New Tree-form Honeysuckle Variety
I. Characteristics and Advantages (1) Wide adaptability. It is drought-tolerant and waterlogging-tolerant, cold-tolerant and not afraid of heat, tolerant of poor soil, and fond of fertilizer and water. It performs well in slightly acidic, slightly alkaline, and neutral soils. (2) High flower-setting rate and many flower needles. The flower needles are thick and long. Compared with traditional honeysuckle, a traditional honeysuckle generally grows 2 flower needles at one node, called "double flowers," while the tree-form honeysuckle can grow 20-50 flower needles at one node, and up to more than 100 in some cases, and they are 1.5 times the length of traditional flower needles.

How to prevent and control frost damage to young and newly planted tea trees? These seven methods must be mastered
1. Apply winter manure. Young and newly planted tea trees have relatively weak cold resistance, so before overwintering, a heavy application of winter manure should be combined with earthing up and mounding around the base. The fertilizer should mainly be farmyard manure, stable manure and biogas residue, which have a certain heat-preserving effect, along with a certain amount of cake fertilizer, superphosphate and potassium sulfate fertilizer. Winter manure can not only preserve heat and prevent freezing and enhance the tea trees' freeze resistance, but also lay a good foundation for the tea trees' growth the following year. 2. Earth up and mound around the base. Preventing the root crown from freezing is a key measure for protecting young and newly planted tea trees from frost. Therefore, before young and newly planted tea trees overwinter, they should

How to prevent and treat gummosis in peach trees? A detailed guide to practical methods
1. Distribution: Peach gummosis, also known as resin disease, occurs commonly in all peach-growing regions of our country, and is especially severe in the south. The causes are complex, and it is not easy to completely control. Gumming weakens tree vigor, affects fruit quality, and can even kill branches and trees. 2. Symptoms: This disease mostly occurs on the branches and trunk of peach trees, and is most likely to occur at the main trunk and the forks of main branches. In the early stage, the diseased part swells slightly and gradually exudes a translucent gum, which worsens after rain. Afterwards the gum gradually becomes jelly-like, turns yellowish-brown after losing water, and becomes dark brown when dry. In severe cases, the bark cracks

What are the control methods for the jujube tree tortoise wax scale?
(1) Manual removal of the pest source: during winter and in early spring in March of the following year, use a stiff-bristled brush to scrape the insects off the branches and collect and kill them. If snow or fog freezes on the branches with a thick layer of ice, you can directly strike the branches to shake off the ice, and the insects will fall with it. (2) Protect and utilize natural enemy resources: this pest has many natural enemies; a single predatory Chilocorus kuwanae can prey on thousands of these insects in its lifetime; the larvae of the long-shield golden small wasp can parasitize under the pest's abdomen and feed on the scale eggs. The larvae of the long-shield golden small wasp can parasitize under the pest's abdomen and feed on the scale eggs. (3) Chemical control:
