How to strengthen cultivation and management during the cotton bud stage? Keep these technical key points in mind
After cotton transplanting this year, continuous drought and little rain, unstable temperatures, and a long seedling-hardening period seriously affected plant development. In addition, large populations of aphids and red spider mites caused severe damage, leading to a second seedling-hardening in cotton seedlings, with a few seedlings showing red stems all the way to the top and true leaves drying up and falling off. Recent rainfall has alleviated the drought, and seedling conditions have begun to improve. Transplanted cotton now has 7-9 true leaves and has begun to form buds, and cotton after wheat (rapeseed) has also begun to develop, but overall seedling conditions are not as good as in previous years. The bud stage is the most important period in the life of cotton, and the following cultivation and management measures should be emphasized

What are the taboos of growing bonsai in summer? Keep these five points firmly in mind
1. Avoid fertilizing. In the high temperatures of midsummer, the leaves lose water quickly. Fertilizing at this time will make the solute concentration of the trunk's cells lower than that of the surrounding environment, causing water in the plant cells to flow back into the soil, and the trunk will die of dehydration due to fertilizer damage. 2. Avoid drought. Watering when you remember and not watering when you forget, sometimes leaving it alone for several days in a row, and only quickly replenishing water once the leaves are found to be wilting, after which the leaves return to normal - this is a response of the trunk to adapt to the environment, but if this goes on for a long time, the excessively strong transpiration will eventually make the trunk difficult to recover from serious damage and die of dehydration. 3. Avoid water

How to classify and manage cotton during the flowering and boll stage? Jinnan District Agriculture and Forestry Bureau reminds cotton farmers
The period from when 50% of cotton plants flower to when 50% of cotton plants mature and open their bolls is called the flowering and boll stage. Cotton in Tianjin generally enters the flowering and boll stage in early July and finishes at the end of August. This period is the key period that determines cotton yield, and cotton farmers are urged to pay attention to the growth trend of cotton in the field and adjust technical management measures at any time. According to Gao Qingming and others of the Cotton Research Institute of the Hebei Academy of Agriculture and Forestry Sciences, based on morphological indicators such as cotton plant growth during the flowering and boll stage, cotton fields are classified into 4 grades: excessive vegetative growth, robust, ordinary, and weak. The main indicators of the 4 grades are as follows: ①

How to manage cotton during the flowering and boll-setting stage? Jinnan District Agriculture and Forestry Bureau reminds cotton farmers to master the techniques
The flowering and boll-setting stage of cotton in Tianjin generally begins in early July and ends at the end of August, lasting 55 days. According to surveys, most of the cotton fields in our district have entered the flowering and boll-setting stage. Field management during the flowering and boll-setting stage is very important. This period is when cotton grows and develops most vigorously, and it is a period of intricate and complex contradictions among vegetative growth and reproductive growth, individuals and populations, and the cotton crop and the environment, so it is the period that determines yield. Cotton field management during this period should focus on doing the following key tasks well: 1. Increase potassium fertilizer application. Increasing

After the Start of Autumn, don't relax on Welsh onion management - keep these key points in mind
Summer goes and autumn comes, and Welsh onion growth enters its vigorous stage. At this time, the main management goal is to promote more leaves and rapid growth, elongate, thicken and increase the weight of the leaf sheaths (the white stalk), and keep the root system strong and firmly established. The field management technical measures can be summarized in four farming proverbs: After the Start of Autumn, don't relax on Welsh onion care, four fertilizers and seven waterings attack in succession, three hoeings and two earthings drain rain and waterlogging, and prevent and control three diseases and six insects. 1. Four fertilizers and seven waterings attack in succession. The four fertilizers refer to the tillering fertilizer (early August), applying 2000-2500 kg of high-quality decomposed barnyard manure, 10 kg of urea or 20-25 kg of ammonium bicarbonate per mu

There's an art to feeding pigs with homemade feed: keep these three precautions in mind

What are the medication precautions for dogs? Owners should keep these points in mind
There are 4 commonly used methods of administration: oral, injection, enema and topical, and each of them has several ways. (1) Oral administration 1) Mixing with feed.

This method is suitable when the sick dog still has an appetite and the drug has no unusual taste, is non-irritating and the dose is not large. 2) Oral dosing. When the dose of tablets, pills or capsules is not large, they can be wrapped directly in soft paper, the sick dog's mouth opened, and the packet placed over the tongue

Four precautions for autumn fishing to keep in mind
First, choose a good fishing time. Fishing should be done on sunny days, around dawn before the fish surface for air. At this time, fishing has the least impact on the pond fish, and the freshly caught fish can be supplied to the morning market in time. In overcast, muggy weather, or when pond fish are surfacing for air or there is an outbreak of fish disease, it is not advisable to seine and catch fish, so as to avoid causing a large number of fish deaths and unnecessary economic losses. Second, stop feeding or feed less before fishing. One day before fishing, feeding should be stopped or the amount of feed reduced, and one must by no means feed large amounts of concentrated feed just to increase the weight of the fresh fish for market. Because

There's a right way to inject medication into a sick turtle, and the precautions must be kept in mind
Because turtles have a very hard shell, once a turtle gets sick, its treatment is very different from that of other animals. Practice has proven that when medicating a sick turtle, injection is the most effective method. The following technical points should be noted when injecting a turtle. 1. Never use long or thick needles. A turtle has little exposed muscle, generally only slightly more muscle at the base of the front and hind limbs, but the area is not large. Therefore, choose a thinner and shorter needle. The injection depth is generally about 0.5 cm for a small turtle, 0.8 cm for a medium turtle, and 1.2-1.8 cm for a large turtle.
