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

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.

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.

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

Four protections to do well in spring field management of wheat
To ensure high and stable wheat yields, after the beginning of spring, four protections should be emphasized in wheat management. First, prevent waterlogging damage. After the beginning of spring there is generally more rain, and if drainage is poor and soil moisture is too high, waterlogging damage is very likely to occur. Ditches should be cleared and drainage carried out in time, and plant ash should be spread between the rows to loosen

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.

How to protect walnut trees from the cold? A detailed guide to cold-protection techniques for walnut cultivation
Because walnut tree branches have a large pith and high water content and poor cold resistance, they are prone to freeze damage in the colder and drier areas of the north, causing branch dieback. Therefore, to ensure the normal growth of young trees and prevent freeze damage, winter cold-protection work should be strengthened to reduce the harm
