Adopting the "three protections" technique in peanut cultivation significantly increases yield
1. Preventing excessive vegetative growth. For peanut fields with relatively high soil fertility, good water and fertilizer conditions, and vigorous plant growth, when growth is too vigorous and excessive vegetative growth occurs, spraying hormones, namely plant growth regulators, can inhibit vegetative growth, promote reproductive growth, and coordinate the relationship between vegetative growth and reproductive growth.

What are the key points for protecting longan from the cold in winter?
1. Cultivate robust autumn shoots. Autumn shoots are the fruiting mother branches of longan for the coming year and are also one of the main branches for longan to overwinter. Whether the autumn shoots are robust affects their ability to withstand cold during overwintering. Therefore, the last autumn shoots of longan are generally best controlled to emerge in mid to late October; before shoot emergence, it is best to

Three Key Protection Techniques for Four-Season Cultivation of Navel Orange
Along with the development of the navel orange industry in Gannan, the management techniques for navel orange throughout the four seasons of the year are becoming increasingly important. 1 Autumn shoot protection. Autumn shoots are the main fruit-bearing mother branches of navel orange, and autumn shoots should be promoted according to different climatic conditions. Generally one week after Minor Heat, nitrogen fertilizer is applied to promote budding according to the fruit load of the plant; after Major Heat the shoots are released; when the buds are half a grain of rice long, spray 25% bisultap 600-fold solution to control citrus leaf miner, spraying once a week until the autumn shoots stop growing; at the same time, spray a shoot-strengthening fertilizer once.

Reporter Yan Zhangwen reports: With the weather continuing cold and rainy, can navel orange trees withstand it? On the morning of January 28, the reporter conducted a telephone interview with Fang Yiwen, director of the Municipal Citrus Science Research Institute. Director Fang Yiwen, who was observing freeze damage on site, told the reporter that in parts of Ningdu, Yudu, Ganxian and other places in the north and central regions, some navel orange orchards at higher altitudes have already suffered freezing damage, with ice forming on the leaves; as temperatures drop, the freezing line will continue to advance toward the southern areas, posing a greater threat to navel orange trees. According to the weather forecast, the rain, snow and freezing weather will continue until the end of this month, and temperatures will continue to drop. There is no time to lose in doing a good job of protecting orchards against freezing, and Fang Yiwen urged the broad community of fruit growers to immediately implement the following emergency measures.

Sun protection, fruit protection and winter cold protection management methods for pineapple cultivation
(1) Sun protection and fruit protection. The development period of the main crop after the crown buds have been removed coincides with midsummer, and the fruit is easily sunburned by direct sunlight, affecting fruit quality. Therefore, sun protection and fruit protection work must be done well. Generally, 1 month before fruit harvest, cover the top with pine needles, fern, mountain grass, etc. Then

How to prevent twig dieback in young pomegranate trees in severe winter? Detailed explanation of cold protection methods
Twig dieback in young pomegranate trees refers to the phenomenon in which some branches shrink and dry out or die after the tree overwinters. In northern China, winters are cold and dry, early spring has little rain and much wind, and evaporation is high, while young pomegranate trees grow a lot each year and the pith of the branches has poor water retention. Therefore, in a severe winter, twig dieback is likely to occur.

Detailed Explanation of Key Points for Frost Protection Techniques in Citrus Cultivation
For fruit trees that have suffered relatively severe frost damage, adopt tree-preservation measures: First, mound soil to increase temperature. Mounding soil protects the root crown; the standard for mounding is that the root system is not exposed and the root crown is covered. Second, whitewash and wrap the branches and trunk. The trunk and main branches form the tree framework and are prone to frost damage, which leads to weakened tree vigor

How to protect citrus leaves in winter? These six measures you need to master
After citrus enters dormancy in winter, 40-60% of the tree's nutrients are stored in the leaves. Therefore, protecting leaves in winter not only helps enhance the tree's cold resistance and promote flower bud differentiation, but also benefits bud break, flowering and fruiting the following spring. Leaf protection measures mainly include the following
