How to select and store sweet potato seed tubers? These methods you need to master
1. Timely harvest: If sweet potatoes are harvested too early, the yield is lower; if harvested too late, they are prone to frost damage, which affects storage. Therefore, it is generally best to begin harvesting when the temperature is around 18°C, and finish harvesting when the temperature is above 10°C (that is, before the frost-kill period). 2. Carefully select tubers: When harvesting and selecting good sweet potato varieties, you must dig and cut carefully to avoid wounds. In order to produce more sprouts, strong sprouts and lower costs, tubers weighing 150-200 g should be selected as seed. The selected tubers must be disease-free, free from flood damage, and also have the typical characteristics of the variety. At harvest,

How to grow spring-planted garlic for high yields? Master these four cultivation points
Garlic planted in spring and harvested in summer has a shorter seedling stage and less nutrient accumulation, so both yield and quality are inferior to autumn-planted garlic. To improve the yield and quality of spring-planted garlic, you must select good varieties and focus on management. The key is to do well in the following four aspects: 1. Choose suitable varieties: spring-planted garlic takes about 100 days from planting to harvest, and the whole growth period is very short, so choose short-growing-period purple-skin garlic as seed garlic. 2. Apply heavy base fertilizer: before sowing, while preparing the land, apply 3000 kg of high-quality human and livestock manure or barnyard manure per mu, 15:

How to rejuvenate 'Ai Datou' garlic? Master these key measures
Tongling County, Anhui Province, China is located in the middle and lower reaches of the Yangtze River. Garlic, as one of the "Eight Treasures of Tongling," has a long history of cultivation, especially the local variety 'Ai Datou', which has a unique flavor and is highly favored by people. Due to various reasons, 'Ai Datou' has shown serious variety degeneration: the per-unit yield of garlic scapes and garlic bulbs has dropped substantially, quality has deteriorated, and a large number of undesirable traits such as single-clove garlic, single-segment garlic and multi-segment garlic have appeared. 1 Causes of variety degeneration in 'Ai Datou' 1.1 Long-term asexual propagation 'Ai Datou' in the Tongling area

Seven key points that must be mastered in ornamental peach cultivation
The ornamental peach is a deciduous flowering small tree of the genus Prunus in the rose family. It likes light and fertilizer, is cold-tolerant and drought-tolerant, and is not tolerant of waterlogged conditions. The flower buds always form in the leaf axils of the new shoots of the current year, with 1 to 2 flowers per node, short pedicels and double flowers. The flowering period is usually from late February to early April. It has been a new favorite of the Guangzhou Lunar New Year flower market in recent years. In terms of management, the "seven musts" should be followed: (1) Timely pruning After the flowers fade, all vegetative branches should be cut back short in time, and crowded branches should be removed to ensure more flowers the following year. (2) Timely fertilizing From bud break

Fertilizing Cotton During the Flowering and Boll Stage Requires Care: Master the Correct Method
Name: Fertilizing Cotton During the Flowering and Boll Stage Requires Care Category: Crop Production Technology / Principles of Plant Physiology and Cultivation Techniques Scope of Application: Unrestricted Detailed Content: The flowering and boll stage is the critical period when cotton gradually shifts from vegetative growth to reproductive growth, and it is also the period when cotton has the highest fertilizer demand. For cotton in full bloom, since vegetative growth is still proceeding alongside reproductive growth, applying excessive nitrogen fertilizer at this time will cause vigorous growth and then excessive vegetative growth, which not only intensifies the shedding of squares and bolls but also triggers premature senescence. Therefore, for cotton in full bloom, the application should

How to fertilize cotton during the bud stage? These methods must be mastered
After cotton squares appear, it enters a period when vegetative growth and reproductive growth proceed together, while vegetative growth still predominates. During this period, a framework must be built for high cotton yields, fully supplying the fertilizer needed during the cotton bud stage. It is necessary both to meet the needs of the cotton plants and to prevent excessive or overly aggressive fertilization that causes excessive vegetative growth. For cotton fields with a low amount of base fertilizer, some decomposed human manure and urine, cake fertilizer, or a small amount of quick-acting nitrogen fertilizer mixed in can be applied at the bud stage, applied deeply in furrows so that the fertilizer gradually decomposes and takes effect at the flowering and boll stage. Spraying New High Lipid Film at the appropriate time greatly increases the effective component rate of the fertilizer.

What to do when a pig gets rheumatism? Master the prevention and treatment methods
I. Causes Rheumatism is a disease caused by triggers such as dampness, cold, insufficient exercise, and sudden feed changes, and is generally believed to be related to hemolytic streptococcus infection.

High-yield garlic cultivation techniques require attention to detail; these key points must be mastered
1. Pay attention to sowing time and sowing rate. The best sowing time is about 3 days after White Dew and about 5 days before the Autumn Equinox. Garlic seed should be sown in three grades: large, medium, and small, at 40,000 plants per mu, with 20 cm row spacing and 8 cm plant spacing. 2. Pay attention to crop rotation arrangement. Planting in muddy fields is preferable; garlic should not be grown continuously, otherwise pests and diseases will increase. The previous crop is best as sesame or soybean; fields previously planted with peanut or hemp crops are not suitable for garlic. 3. Pay attention to scientific fertilization. First apply sufficient farmyard manure, and also apply an appropriate amount of chemical fertilizer. On farmland with good soil quality, less chemical fertilizer can be used, but phosphorus and potassium fertilizer

Key points of two-season garlic cultivation techniques, master the method of growing two seasons in one year
Two-season garlic means growing one season of early green garlic and one season of plastic-film garlic within the year. Cultivating garlic can effectively improve land utilization and achieve "three plantings and three harvests" or "four plantings and four harvests" in one year, while also significantly increasing income. According to surveys, the per-mu output value of second-crop garlic increased by 52%-46.6% and 111.1% compared with single-season green garlic and single-season harvested garlic respectively; the per-mu net income increased by 53.3%-45% and 76.9% compared with single-season green garlic and single-season harvested garlic respectively.

How to care for lilies in summer? Master these care tips
Lilies come in a wide variety of colors and varieties, with large, trumpet-shaped flowers, and are widely loved because their name carries the meaning of "a harmonious union lasting a hundred years" and "a heart in harmony with all things." Summer is the main flowering and dormancy period for lilies, and care and management during this time is very important. Cooling and sun protection. The suitable growing temperature for lilies is 15°C to 25°C, within which they can maintain good growth and flowering. When flowering, the potted plants can be moved to a shaded spot, or a screen can be placed over the plants for shade, along with enhanced ventilation and cooling, which helps extend the flowering period. Lily bulbs cannot tolerate
