How to apply top dressing in the later stage of edible fungi? These methods must be mastered
In the later stage of mushroom fruiting, in order to enhance the stamina for fruiting, mushroom growers often use various means to add nutrient solutions for top dressing. But only by using the correct method of addition can the expected goal be achieved. Otherwise, it is like pulling up seedlings to help them grow, achieving the opposite effect and bringing losses to producers. 1. Pay attention to the method of addition. There are usually three methods for adding nutrient solution: spraying, soaking and filling holes. The time for spraying nutrient solution is suitable when fruiting bodies appear in large numbers. When spraying, care should be taken that the nozzle is not directly facing the fruiting bodies, and at the same time pay attention to the "four no-spray" rules:

Symptom Identification and Control Methods of Spruce Bud Rust
Spruce bud rust is a newly discovered disease in the forest regions of northern China. It has been reported in the natural forest areas of the Greater Khingan and Lesser Khingan Mountains. Abroad, it is mainly distributed in countries such as the United States, Canada and Sweden, where it damages white spruce, black spruce and Norway spruce. It harms the terminal buds and lateral buds of seedlings, saplings and mature trees, seriously affecting seedling quality and the normal growth of plantations. Symptoms appear in late May when new leaves begin to grow. During the same period, diseased buds grow faster and longer than healthy buds, but soon stop growing. The diseased leaves growing from diseased buds

Rose Winter Cutting Methods and Technical Key Points
From mid-October to early November, in conjunction with winter pruning of roses, select branches with evenly spaced internodes and plump dormant buds, remove the leaves, and cut them into 10 cm long cuttings (about 3 nodes), with the upper end cut flat and sealed with paint, and the lower end cut at an angle for later use. 2. Preparation of seedbed and nutrient bags: Choose a plot that is sheltered from the wind, faces the sun, has flat terrain, and loose soil, and make a seedbed 1 m wide, 5-6 m long, and 20-30 cm deep. Mix fully decomposed nutrient soil and fine sandy soil in equal halves to make moist nutrient soil, and treat with zinc

A Detailed Guide to the Harm Caused by the Jujube Leaf Beetle and Its Control Methods
The jujube leaf beetle belongs to the order Coleoptera, family Chrysomelidae. The larvae and adults of this insect damage jujube leaves and tender shoots. In outbreak years, the leaves are eaten bare, leaving only the bare fruiting branchlets, which greatly affects yield. The peak damage period for this insect is from mid-April to mid-May. Both larvae and adults damage jujube leaves, tender shoots, flower buds and flowers. Control methods: spraying mainly for flower protection is the primary approach. During the occurrence period of larvae and adults, spray 90% trichlorfon at 1500 times dilution or deltamethrin at 1.5 ten-thousand to 1.6 ten-thousand times dilution; generally the insecticidal effect is very good.

Harvesting, Processing Methods and Key Technical Points for Dwarf Lilyturf (Ophiopogon japonicus)
Dwarf lilyturf is harvested in the first or second ten days of April of the second or third year after planting. Choose a sunny day, first plow the soil to a depth of 25 cm so that the dwarf lilyturf is turned up, shake off the soil, cut off the tuberous roots and fibrous roots, put them separately into bamboo baskets, and place them in running water, trampling and rubbing them with the feet to wash away the mud and sand. Spread the washed dwarf lilyturf on a drying mat or in a drying yard to sun-dry; once the water has dried, rub it gently with the hands, then sun-dry again after rubbing, repeating this several times until the fibrous roots are rubbed off, then sun-dry until completely dry, and sieve out impurities to finish.
