Potato Intercropping Cultivation Models and Key Technical Points
To improve land utilization and increase farmers' income, several intercropping and relay-cropping models with potato as the main crop are introduced here, for the reference of farmer friends and grassroots leaders in adjusting the agricultural structure. 1. Potato-cotton. Potatoes are sprouted in late January and sown in mid-to-late February, using plastic film mulch cultivation. The varieties selected are virus-free potatoes Zheng Yin No. 5 and Zheng Yin No. 7, bred by the Zhengzhou Fruit Research Institute of the Chinese Academy of Agricultural Sciences; for cotton, the large-plant, disease-resistant Biao Za A1 is preferable. Potatoes are planted in double rows on high ridges, with wide rows of 8

How to Store and Preserve Peaches? Key Technical Points Explained
Some peach varieties ripen in the high-temperature summer season, and their harvest maturity and eating maturity are reached almost simultaneously; in addition, the fruit is soft and juicy with poor storability. However, storability varies greatly among varieties. Honey peaches have the worst storability and can only be stored for about 1 week, while late-maturing varieties such as Fei peaches, winter peaches and Qingzhou honey peaches are more storable. The problems that peaches are prone to during storage include: over-ripening and softening, rot caused by pathogens, and chilling injury. The main technical measures adopted in production are: 1. Immediately pre-cool the fruit after harvest: immerse the fruit in 0.5-1°C

Control Methods and Technical Key Points for the Jujube Inchworm
Also known as the jujube looper or "arched-back worm," it is the "number one enemy" harming jujube trees. Its larvae damage young buds, young leaves, and flower buds, and spin silk that tangles and hinders leaf expansion; in severe cases they can strip all the leaves, while also causing heavy damage to crops such as apple, pear, peach, potato, and chili pepper. The jujube inchworm begins to emerge from the soil in mid-March, and when the jujube buds begin to swell, the larvae start hatching and damaging the jujube buds. Its main biological characteristics are: 1. One generation per year, overwintering as pupae concentrated in the surface soil around the root collar of jujube trees;

Pruning Methods and Technical Key Points for Flowering Peach During the Growing Season
In northern gardens, the flowering peach (Prunus persica) is an indispensable ornamental tree species for early spring. Its tree form is graceful and its flowers are charming, giving an excellent ornamental effect. However, it grows vigorously and produces many branches, and its canopy becomes dense, causing excessive nutrient consumption and poor ventilation and light penetration, which is unfavorable for branch ripening and flower bud differentiation. Therefore, it should be timely shaped and pruned, especially pruned during the growing season (also called summer pruning), which plays a rather important role in the cultivation and management of flowering peach. Summer pruning can reduce ineffective growth, save nutrients, improve light conditions, strengthen nutrient synthesis, and

Control Methods and Key Technical Points for the Peach Borer
The peach borer, also known as the peach fruit borer, peach fruit worm, peach borer worm, etc. It belongs to the order Lepidoptera, family Pyralidae. 1. Morphological characteristics: The adult is about 12 mm long, with a wingspan of 22-25 mm, orange-yellow, with more than 20 black spots on the forewings and more than 10 on the hindwings. The eggs are oval, initially milky white, turning reddish-brown before hatching. The larva is 22 mm long, with a dark brown head and neck, a pale red back, and several pale brown spots on each body segment. The pupa is about 13 mm long, brown, with 6 curled anal spines at the end of the abdomen.

Key Technical Points for Planting Birchleaf Pear Rootstock Seedlings in the Rainy Season
Birchleaf pear (Pyrus betulifolia) is an excellent rootstock for grafting pear cultivars, being drought-resistant, cold-resistant and tolerant of poor soil. It is generally planted in spring and autumn, but in remote mountainous areas short of water, the difficulty of transporting water and spring drought often affect the survival rate of planting. Fruit growers in our region have experience with planting birchleaf pear rootstock seedlings in the rainy season, which gives a high survival rate, rapid orchard establishment and low cost. The specific methods are as follows. 1 Plant after the continuous rainy season arrives, when the underground water content is close to saturation; planting in the rain or rushing to plant before the rain is best. 2 Dig up birchleaf pear sucker seedlings from nearby hillsides; generally a seedling diameter of 0

Management Methods and Technical Key Points for Adult Scorpion Breeding
The Chinese scorpion (Mesobuthus martensii) generally enters the adult stage after molting 6 times. At this point, individuals that are large and robust can be selected as breeding scorpions. The period from April to September is the breeding and mating season for scorpions. Female and male scorpions can be kept together in a ratio of 3:1 and allowed to mate freely. The site for breeding scorpions should be clean and quiet, with more fresh, juicy, and nutritious food provided, and the temperature and humidity should be suitable. The density of breeding scorpions should be reduced appropriately. During the period when the female scorpion is carrying young, its nutritional requirements are greater and better than those of ordinary scorpions. Therefore, more fresh and juicy insects should be fed.

Detailed Explanation of Key Technical Points for Soil, Fertilizer and Water Management of Geraniums
Soil, fertilizer and water management techniques for geraniums: When geranium seedlings reach 12 to 15 cm in height, pinch off the growing tips to encourage side branches. During the high temperatures of midsummer, strictly control watering; otherwise, if the potting soil of a semi-dormant geranium is too wet, the leaves often turn yellow and drop off. During the stem and leaf growth period, fertilize once every half month, but do not apply too much nitrogen fertilizer. If the stems and leaves grow too vigorously, stop fertilizing and appropriately remove some leaves, which helps flowering. During the flower bud formation period, apply an additional phosphorus fertilizer once every 2 weeks. Or use "Huiyou" 15-15-30 special fertilizer for potted flowers. In order to control the height of the excavated plant and achieve

Fertilization Management Methods and Technical Points for Pelargoniums
Pelargoniums are plants of the genus Pelargonium (Pelargonium), with more than 250 species in the genus, as well as various hybrids. The main types include zonal pelargoniums (English: Zonal Pelargoniums, Latin scientific name Pelargonium x hortorum), ivy-leaved pelargoniums (also known as peltate pelargoniums, English: Ivy-Leaved Pelargoniums, these plants originate from P. peltatum

Control Methods and Technical Key Points for Physiological Diseases of Button Mushrooms
Button mushrooms are relatively sensitive to their environment. A poor cultivation environment will hinder their normal growth and development, produce various abnormal phenomena, and lead to reduced yield and lower quality. Common physiological diseases of button mushrooms include excessive mycelial growth, hard opening of the caps, thin-skinned early opening, and the appearance of soil-level mushrooms and hollow-stemmed white-core mushrooms. They are described below: Symptoms of excessive mycelial growth: after the mushroom bed is cased and watered, the fluffy mycelium of the button mushroom will continuously grow toward the surface of the fine soil. In severe cases, it will form a fine, water-impermeable mycelial mat, thereby delaying the time of fruiting and reducing the mushroom
