A Detailed Guide to Common Pests and Diseases of Plum Trees and Their Control Methods
After the first pinching of plum trees, pinch the new secondary shoots when they reach 20 cm, and pinch the developing branches when they reach 60-80 cm. If there are many branches, some can be thinned out; if the branches are not too dense, thin as little as possible and rely more on control. Before mid-July, clear all weeds from the orchard. 1. Bacterial shot hole disease, can use carbendazim...

Correction Methods for Nitrogen Deficiency in Nectarines
Soil nitrogen deficiency can turn the leaves of the whole tree from light green to yellow. The petioles and veins turn red. At this point, the growth of new shoots is hindered, leaf area decreases, and the branches and leaves become relatively hard. If the nitrogen deficiency is too severe, within 1 to 3 weeks, red or reddish-brown spots appear in the mesophyll between the large veins. In the later stage, many...

Peach Tree Powdery Mildew: Control Methods and Key Technical Points
Control methods for peach tree powdery mildew: 1. After leaf fall, remove diseased leaves to reduce the source of infection. 2. Spray fungicides for protection during the growing season: in the early stage of the disease, spray 0.2 to 0.3 degrees Baume lime sulfur mixture, or a 2000 to 3000 times dilution of 15% wettable powder triadimefon, or a 1500 to 2000 times dilution of thiophanate-methyl. 3. Improve ventilation and light penetration...

How to control alternate bearing in plums? These methods are essential
Plum trees have been cultivated in China for more than 3,000 years. The Book of Songs records "the blossoms are peach and plum" and "you throw me a peach, I return you a plum." The Guanzi states, "On the five fertile soils, the trees suited to them are plum and apricot." This shows that plum trees and apricot trees have a long history of cultivation in China and adapt well in both the north and the south. But for a long time, our...

What Are the Symptoms of Phosphorus Deficiency in Peach Trees? Detailed Guide to Prevention and Control Methods
I. The Role of Phosphorus in the Growth and Development of Peach Trees Phosphorus has two roles in the growth and development of peach trees. On one hand, it can strengthen tree vigor, maintain healthy tree growth, promote flower formation, lead to earlier fruiting, promote the maturation of fruit and seeds, increase sugar content, and improve fruit quality. On the other hand, it can enhance the peach tree's adaptability to the external environment...

Peach Tree Pest and Disease Control Methods and Technical Key Points
1. Note that peach trees are chlorine-sensitive crops. Applying chlorine-containing fertilizer easily causes root rot and yellowing leaves; in mild cases the tree vigor weakens, and in severe cases the plant dies. Therefore, do not apply chlorine-containing fertilizers. 2. Be careful about watering during the flowering period. Watering during flowering can easily lower soil temperature and reduce soil air content, affecting root growth and absorption, leading to...

A Detailed Guide to Dragon Fruit Cultivation Techniques and Field Management Methods
I. Orchard Establishment Dragon fruit is relatively heat-tolerant, water-tolerant, and prefers warm, humid, sandy soil rich in organic matter. Before planting the seedlings, set up 100-110 square concrete pillars measuring 10×10×250 cm per mu at a spacing of 1.5 m × 2 m, with the concrete pillars buried 50 cm into the soil to support the climbing dragon fruit branches. On both sides of each concrete pillar, at 5-1...

Detailed Explanation of Dragon Fruit Propagation Methods and Key Technical Points
1. Cuttings are best taken in spring and summer. Select plump, well-grown stem segments about 15 cm long as cuttings. After the wound has air-dried, insert them into a sand bed; roots will form in about 15-30 days, and once the roots reach 3-4 cm, they can be transplanted to the seedling bed. 2. For grafted seedlings, select healthy, pest-free, vigorously growing "Liangtianchi" (a wild cactus genus plant) with plump stems as rootstock...

Pitaya (Dragon Fruit) Water and Fertilizer Management Methods and Precautions
Pitaya is relatively drought-tolerant. Water once every 2 to 3 days in the early stage after planting, and thereafter just keep the soil moist. The root system of pitaya is distributed relatively shallowly, so fertilizer should be applied in small amounts but frequently to prevent root burn and root rot. After the planted seedlings sprout, apply dilute human manure and urine in the planting hole about 10 cm from the seedling, about 1 kg per plant, and thereafter...

Strawberry Summer Pest and Disease Control Methods and Precautions
Applying Boron and Iron Fertilizer Can Improve Strawberry Quality. Strawberries are currently being marketed in large quantities, but as strawberries grow and fruits are harvested, farmers neglect the application of micronutrient fertilizers, and combined with unreasonable fertilization, this causes a deficiency of trace elements needed for strawberry growth, especially with boron and iron deficiency symptoms being particularly obvious, which has already affected strawberry yield...
