How can citrus cultivation be protected against drought and made drought-resistant?
How can citrus be planted to prevent and resist drought? Please give guidance. Citrus cultivation is prone to damage from spring drought and summer drought. Spring drought mainly occurs from February to May, and the damage shows as affected flower bud differentiation, water loss in late-maturing citrus, and abnormal flower drop during the flowering period; leaf curling, an increase in deformed flowers, granulation and water loss of the fruit segments, and declining quality. In high temperature and drought during the flowering period, the flowering period shortens, affecting pollination and fertilization...

Ten management practices for protected cultivation of apricot trees
Because large flat apricot trees are cold-resistant and drought-resistant, they are mostly planted on poor, barren slopes, and because their root systems are strong and spread throughout the orchard, plowing and turning the soil is difficult. In addition, the land preparation standard at planting time is not high, which often leads to soil compaction, poor permeability, easy occurrence of soil-borne diseases (such as root rot), difficult fertilization, and laborious intertillage, ...

Spring Pest and Disease Control Methods for Protected Plum Trees
1. Mound soil at the base of the trunk. Before overwintering adults emerge from the soil (mid to late May), build a 10 cm thick mound of soil around the tree basin and tamp it down firmly so that emerging adults cannot come out of the soil. 2. Apply pesticide to the ground. Before overwintering adults emerge (after petal fall), spray the tree basin with 75% phoxim emulsifiable concentrate at 0.5 kg/mu, or 40...

Detailed Explanation of Key Techniques for Protected Cultivation of Strawberries
Strawberry is a berry plant commonly cultivated around the world. It is rich in nutrients, with juicy, sweet-and-sour, tasty fruit. It propagates easily and delivers quick returns; with certain measures, planting in the same year can bear fruit in the same year. Like cucumbers, tomatoes and other vegetables, strawberry varieties with different ripening periods can be reasonably combined in planting or...

When is the covering time for protected cultivation of apricots?
For most apricot varieties, they must undergo a low-temperature period of 700-1000 hours below 7.2°C to break dormancy. Therefore, protected cultivation must raise the temperature only after the apricot's chilling requirement has been met, for success to be possible. If the temperature is raised too early, the apricot trees cannot sprout and bloom normally, and in severe cases it will cause a large number of flower buds to drop, uneven flowering, and severe flower and fruit drop. The timing of temperature increase should also be carefully decided based on the variety's chilling requirement and weather conditions. 1. Covering time for plastic greenhouses: Plastic greenhouses have poor insulation performance, so apricot trees must pass dormancy under natural conditions. The suitable covering time is generally from late January to early February, and the covering time is the temperature-raising time. If the weather is abnormal, such as a warm winter, the covering time should be appropriately delayed. For plastic greenhouses, ground film should be applied 15-20 days before covering to allow the soil temperature to rise slowly.

What are the key points for choosing peach varieties for protected cultivation?
The correctness of variety selection is the key to successful protected cultivation. The purpose of protected cultivation of peach trees is to bring them to market early, so when selecting varieties, priority should be given to early-maturing and extremely early-maturing varieties with a short development period. A fruit development period of 60 to 70 days is appropriate, and no more than 80 days. Varieties should also have a short natural dormancy period and a low chilling requirement (cumulative chilling below 7.2°C of less than 850 hours), abundant pollen, a high self-fruitfulness rate, high yield, large fruit, good fruit quality, and tolerance for storage and transport. If they can
