What are the key technical points for summer management of kiwifruit?
1. Preventing wilting. Kiwifruit leaves wilt during the high temperatures of summer, mainly for two reasons: first, high temperature and drought, mostly occurring between 12 noon and 4 pm on sunny days, recovering in the morning and evening, usually occurring over large areas. When this happens, irrigate promptly in the morning and evening, and the wilting will be relieved. Second, the root system suffers from root rot, root-knot nematode disease, etc., which damages root function and causes pathological wilting. It is most severe at noon and lasts a long time; in severe cases symptoms also appear in the morning and evening, and it tends to occur sporadically. Once discovered, dig down to check the roots. If it is indeed caused by pests or disease, appropriately prune branches and leaves, remove some or all of the fruit, and use agents such as Nongkang 120 and Junlimie for root drenching.

Control Methods and Technical Key Points for Gray Mold in Greenhouse Chinese Chives
When humidity inside a greenhouse for Chinese chives is high, gray mold is likely to occur. After the disease develops, pale grayish-brown to white spots gradually appear on the leaves from the tip downward, on both the upper and lower surfaces; after expanding, they become elliptical or spindle-shaped lesions and merge with each other into large dead patches. When air humidity is above 85% and the temperature is 15°C~20°C, warm and humid conditions favor the occurrence of this disease.

Key Technical Points for Light Regulation in Greenhouse Grape Cultivation
In greenhouse grape cultivation, because the light intensity inside the shed is often less than 70% of that outdoors, it has a significant adverse effect on grape growth and fruiting, often causing serious flower and fruit drop, poor fruit coloration, low sugar content, poor flower bud differentiation and other phenomena, greatly reducing grape yield and quality. Therefore, enhancing...

What are the key technical points for spring grape management?
Spring is the season when grapes bud and unfold leaves, canes extend, and clusters form and flowers set fruit. Strengthening spring grape management can improve grape yield and quality. From mid-to-late February to early March, during the budbreak stage, irrigate to promote budbreak and apply quick-acting nitrogen fertilizer. At this stage, orchards with the conditions should irrigate the whole orchard promptly to ensure uniform budbreak. And at this time...

Key Technical Points for Spring Garlic Production Management
First, ensure adequate water supply. As garlic enters the critical water-demand period of bulb expansion, combined with rising temperatures and more frequent windy weather, garlic's demand for water increases. Garlic growers should pay full attention to water management in garlic fields and strive to give one general irrigation (watering) for bulb expansion, so as to meet the water demand for bulb expansion....

Key technical points for hand pollination of watermelon
(1) Flower-to-flower pollination method: Gently lift the female flower's stalk so that the stigma is exposed, then select a male flower that opened the same day, pick it together with its stalk, turn the petals outward to expose the stamens, and gently smear the pollen onto the stigma of the female flower at the fruit-setting node, so that the pollen is evenly scattered on the stigma. Generally, 1 male flower can pollinate 2...

A Complete Analysis of the Key Technical Points of Cherry Cultivation
(1) Soil management. For soil management, a good foundation must first be laid before planting, and the soil must also be continuously improved after planting. 1. Expanding the planting hole and deep plowing. The method is to start from the edge of the planting hole and expand outward every year or every other year, digging a ring-shaped trench about 50 cm wide and 60 cm deep, until the deep plowing trenches between two trees connect. Deep plowing...

Key Technical Points for Topdressing Management in Onion Cultivation
I. Selecting Superior Varieties In production, purple-skinned varieties such as Ziyu No. 1, Ziyu No. 2, Zixing, and Shuanghuanhong can be selected. These varieties have the characteristics of strong pungency, high yield, excellent quality, and suitability for export. These varieties generally yield about 5,000 kg per mu, and high-yielding plots can reach 7,500 kg per mu. II...

Key Technical Points for Early, High-Yield and Efficient Cultivation of Sweet Cherry
1. Selection of Orchard Site Based on the characteristics of sweet cherry, such as drought tolerance, poor waterlogging tolerance, poor cold tolerance, poor saline-alkali tolerance, and shallow root system, the sweet cherry orchard site should be selected in areas with deep soil layers, loose loam or sandy loam soil, low groundwater level, no water accumulation, good drainage and irrigation conditions, and not prone to wind damage. In areas with high groundwater level, overly heavy soil...
