Technical Points for Spraying Foliar Fertilizer on Cotton to Increase the Boll Setting Rate
This year, the summer-ripening crops in Haimen City were delayed in maturity due to climate effects, and after the summer harvest there was a continuous drought until mid-July, when it rained heavily for several consecutive days. This weather pattern of drought followed by rain was very unfavorable for the survival and growth of the already delayed transplanted cotton, and the growth process was delayed by about 10 days compared with normal years. To increase the formation speed of flower buds in the late stage of cotton and improve the boll setting rate, it is recommended to strengthen fertilizer management in the late stage by means of foliar spraying. 1. Combine pest control with proper timing of fertilizer application. Not every pest control treatment requires

How to prevent and control cotton seedling-stage diseases? Detailed prevention and control measures for Binzhou City
There are many types of cotton seedling-stage diseases, and the most serious ones at the cotton seedling stage in our city are damping-off, anthracnose and red rot. In recent years, the first two diseases in particular have been more severe than in previous years. Doing a good job in preventing and controlling cotton seedling-stage diseases is the key to whether our city's cotton can increase both yield and income. At present, the key to preventing and controlling cotton seedling-stage diseases is to implement the plant protection policy of "prevention first, integrated control." 1 Symptoms of cotton seedling-stage diseases 1.1 Damping-off The obvious symptom of field infection is the appearance of elongated

How to prevent and control cotton seedling diseases? Detailed spring prevention and control methods
In recent years, due to low temperatures in spring, seedling diseases in direct-seeded cotton fields have occurred severely, causing large numbers of dead seedlings in cotton fields. In order to improve the economic benefits of cotton farmers and reduce the losses caused by diseases, the symptoms and prevention and control methods of several cotton seedling diseases are introduced as follows: 1. Symptoms of damaged cotton seedlings 1. Anthracnose: Both leaves and stems can be affected. After the seedlings are damaged, reddish-brown spindle-shaped streaks appear at the base of the stem, with longitudinal cracking. In severe cases, the lesions expand, turn brown, blacken, and rot, leading to seedling death. When the weather is humid, the lesions produce orange-red sticky substances.

Getting the five key steps right in Gastrodia elata cultivation can effectively increase yield
To achieve stable and high yields of Gastrodia elata, the first thing is to get the five pre-planting steps right: First, choose the site. Gastrodia elata cultivation can be adapted to local conditions, whether indoors, in air-raid shelters, semi-basements, or chicken coops. Because Gastrodia elata likes dark, damp, and cool environments, choose places with good ventilation and shade as much as possible, with semi-basements and outdoor trenches giving the best results. You can lay a layer of bricks before use, or increase the thickness of the bottom sand layer to enhance its water permeability. Second, if the indoor floor is concrete, use high-quality Armillaria mellea fungal material (spawn). Armillaria mellea fungal material

How to Increase Gastrodia elata Yield? The Three-Switch Measures Are Key
Gastrodia elata is a fine medicinal herb and has been selling well in the market in recent years. The farmers of Chalu Village, Baoshan Town, Fengcheng City, Liaoning Province, regard developing Gastrodia elata production as an important path to wealth; more than 40 households in the village grow Gastrodia elata and earn considerable income every year. Li Jingrong, a retired cadre of the village, has grown Gastrodia elata for 14 consecutive years and accumulated rich experience. He found that the yield of artificially cultivated Gastrodia elata tends to decline year by year. There are mainly 3 reasons: first, because self-bred and self-propagated tuber seeds are used year after year, the degeneration is severe; second, because self-bred and self-propagated fungal strains are used year after year,

The broken-planting technique for oyster mushroom logs helps increase yield
For oyster mushrooms cultivated in mushroom bags, the yield drops greatly after 2-3 flushes of mushrooms. If the temperature rises, the quality will also be reduced. How can later flushes be cultivated to equal or even exceed the yield of the previous flushes? Below is a simple and practical method - the broken-planting method. Remove the plastic bags from mushroom bags that have produced 2-3 flushes, then scrape the old surface layer once, and soak in 5% lime water. If the mushroom logs are relatively dry, also soak in 1% salt water for half a minute. Before soaking, poke a hole through the mushroom log from top to bottom so

Causes of Lily Disease Epidemics and Integrated Control Techniques
I. Symptoms: They appear on leaves, stems and bulbs. When leaves are infected, leaf blight results. At first the leaf tip turns brown, with a length of 1-2 mm, then gradually worsens, and the lesion expands into a nearly triangular shape, becomes thinner, and takes on a dried-up appearance with cloud-like patterns on it. Lesions are generally 17-28 mm long and 5-8 mm wide; the largest lesion is 56 mm long and 12 mm wide. Eventually the leaf dies. Some also occur at the leaf margin as semi-elliptical brown lesions, which can also cause leaf death. Ground

A Detailed Guide to the Control Strategies and Methods for Lily Diseases
Control of Phytophthora blight (1) Adopt high-ridge, deep-furrow cultivation or ridge planting, and keep the bed surface level to facilitate drainage. When diseased plants are found, dig them out early and burn them in a centralized manner or bury them deep. (2) Adopt a balanced fertilization technique, appropriately increase the application of potassium fertilizer, and improve disease resistance. (3) At the early stage of the disease, spray 40% fosetyl-aluminum wettable powder at 250 times dilution, or 58% metalaxyl and mancozeb wettable powder, 64% oxadixyl and folpet wettable powder at 500 times dilution, 72% DuPont Curzate wettable powder at 800 times dilution.

Symptom Identification and Control Methods of Lily Viral Diseases
Common lily viral diseases include the yellowing-wilt type and the mosaic type. In the yellowing-wilt type, no special lesions appear on the leaves; the entire plant takes on a yellow color, and the internodes shorten. The plant becomes dwarfed, and the leaves yellow and shrivel. In the mosaic type, irregular pale green mottling appears on the leaves, then the small pale green areas join and expand, forming slender yellow streaks along the veins, which later become slightly sunken and turn pale yellowish-brown to reddish-brown. The virus mainly overwinters in the bulbs and becomes the source of primary infection the following year; secondary infection in the field is mainly caused by transmission by aphids. When there are many diseased bulbs, the weather is dry, and aphid populations are
