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

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

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

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 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,

Pruning honeysuckle can increase yields; mastering the method is key
Experiments have shown that pruning aging honeysuckle in early autumn can achieve a bumper harvest of honeysuckle the following year. In the production of Chinese medicinal materials, pruning honeysuckle, especially pruning it in early autumn, is an effective technical measure for regulating stem and vine growth, promoting flower bud differentiation, extending plant lifespan, and ensuring stable, high yields. Pruned honeysuckle can generally increase yields by 35-45%, with some reaching more than double. After pruning measures are taken for honeysuckle plants entering the aging stage, their flowering period can also be extended by 5-6 years. When honeysuckle enters the aging stage

How to prevent and treat selenium deficiency in raccoon dogs? Farmers need to master these methods
Selenium deficiency has obvious regional characteristics. Generally, a selenium-deficient geological environment causes selenium deficiency in humans and livestock, especially in years with abundant autumn rain, when selenium in the surface soil is lost with the rainwater, and herbivorous or omnivorous animals find it difficult to obtain enough selenium from plants, thus causing selenium deficiency. The narrow belt from Northeast to Southwest China is all selenium-deficient areas, with western Heilongjiang Province and Liangshan in Sichuan being the most deficient. In selenium-deficient animals, the selenium concentration in the organs and tissues of the body decreases. Under actual production conditions, liver necrosis may occur, or it may appear together with muscular dystrophy, mulberry heart, and white muscle disease. Clinically, various animals show different manifestations, but the common manifestations are decreased productivity, reduced number of offspring, infertility, movement disorders, and in mammals, retained placenta. When raising animals in selenium-deficient areas, attention should be paid to selenium supplementation.

How can fox farming profits be increased? Master these measures
1. Lower feeding costs. First, establish reasonable feeding standards and prepare daily rations according to those standards. Do not arbitrarily raise the ration level. During the fox's breeding period, meat, egg and milk feeds should be used rationally, while during the non-breeding period, cheap marine trash fish and meat by-products may be used appropriately, but the nutritional needs of the fox must never be ignored. For example, feeding poor-quality feed during the winter fur growth period will lower pelt quality, or cause delayed pelt harvesting, which instead results in greater economic loss. Second, feed losses in quantity and quality during purchasing, transport, storage and processing

How to prevent rabbit breed degeneration? Master these practical methods
Causes of degeneration: Extensive management and inbreeding. Only emphasizing the rabbit's trait of eating grass without supplementing with concentrated feed causes nutritional deficiency and breed degeneration. Ignoring the blood relationship of breeding rabbits and mating closely related animals causes poor disease resistance in offspring rabbits, slow growth, smaller body size, deformities, and breed degeneration. Lack of strict selection measures: not paying attention to selecting and retaining breeding rabbits according to breed characteristic requirements, often selling off the large, fast-growing, well-conditioned ones first and keeping the small, thin, weak ones to continue raising, causing gradual breed degeneration. Mating

How Do You Identify an Excellent Racing Pigeon? Master These Selection Techniques
Selecting excellent racing pigeons is like picking athletes. Internationally, there are two major categories of pigeon racing: one is the "evaluation show," and the other is the speed race, that is, the performance race, which is further divided into short and medium distance, and long distance and ultra-long distance. An excellent racing pigeon must be moderate in size. Balance and coordination are the most critical conditions shown by the appearance of an excellent racing pigeon, and length and weight are closely related to the balance and coordination of the whole body. Among champion pigeons, there may be racing pigeons that are too large or too small in body type, but most champion pigeons are moderate in size.
