What to do about false rooting in rose cuttings? Teach you effective prevention methods
Autumn is a great time for softwood cuttings of roses. At present, cuttings are still the main method of propagating roses. It can not only maintain the characteristics of superior rose varieties, but also has a high propagation coefficient, a short production cycle, low input and quick results, and is still adopted by many flower growers. However, in the process of rose cuttings, "false rooting" often occurs due to lack of experience or improper methods. That is to say, 5-10 days after the rose is cut, the axillary buds on the cutting have already sprouted or produced shoots and leaves, and it looks as if it has taken root, but soon it wilts and dies. To avoid rose cut

How to control wheat aphids? Three measures to improve control effectiveness
Wheat aphids are one of the main pests currently harming wheat. In recent years, due to changes in climatic conditions, a decrease in the number of natural enemies, and improper control measures in wheat fields, the harm caused by wheat aphids has become increasingly serious, resulting in reduced wheat yield and declining quality. In response to farmers' situations in controlling wheat aphids, taking the following three measures can improve the control effectiveness of wheat aphids. Determine whether to control based on the control threshold. The control threshold for wheat aphids is 500 aphids per 100 ears. As long as a field reaches the control threshold, pesticide control should be applied immediately. Controlling according to the control threshold not

What effect does airflow have on the growth of pigs?
The effect of airflow on the pig's body mainly influences heat loss from the pig. Under general environmental conditions, as long as airflow exists, it can promote convective heat loss and evaporative heat loss from the body. When the ambient temperature is below the lower limit of the pig's suitable temperature, the effect of airflow increases the amount of heat lost from the pig's body, making the pig feel cold; at this time, in order to maintain body temperature, more energy must be consumed. Conversely, when the ambient temperature is above the upper limit of the pig's suitable temperature, because airflow helps the pig's body dissipate heat, and when the airflow is strong more heat is lost, increasing the wind speed

Normal pre-winter use of tribenuron-methyl has little effect on succeeding cotton
Liu Wenzhang from Hengjing Town, Gaoyou City called to say that he sprayed tribenuron-methyl in his wheat field for chemical weed control, using the product according to the instructions, with the per-mu rate of 10% tribenuron-methyl at less than 15 grams. He heard that tribenuron-methyl, chlorsulfuron and metsulfuron-methyl belong to the same class of herbicides, and that chlorsulfuron and metsulfuron-methyl both have very long residual activity periods, often causing residual phytotoxicity to succeeding crops. He did not know how long the residual period of tribenuron-methyl is, and whether a field sprayed with tribenuron-methyl before winter would suffer from herbicide residue effects when cotton is planted as the succeeding crop. Tribenuron-methyl is a commonly used herbicide for controlling broadleaf weeds in wheat fields. Wheat, large

Secondary bagging of edible fungi can effectively prevent infection
In the production of shiitake mushrooms (Lentinula edodes), lion's mane mushrooms (Hericium erinaceus), wood ear mushrooms (Auricularia heimuer) and others, the secondary bagging technique is applied (that is, when the mushroom logs come out of the sterilization chamber, an extra layer of thin film bag is put on, so that the mushroom logs inside the bag do not come into direct contact with the ambient air), which effectively solves the problem of cross-infection during the log production process and keeps the strain survival rate above 97%. The technique is described below: 1. Preparation of the outer bag The outer bag should preferably be a low-density polyethylene film bag with a circumference 2 cm larger than the inner bag, a length 5 cm longer than the inner bag, and a thickness of 0.2 silk, with one end tied and sealed for later use.

Which insecticide is effective for controlling the rice stem maggot?
The rice stem maggot has broken out and caused disasters in most rice-growing areas in China in recent years, making it a serious pest. At present, an insecticide for controlling pests such as the rice stem maggot has been successfully invented. The purpose of this invention is to provide a highly effective and low-toxicity insecticide specifically for controlling the rice stem maggot pest. The insecticide of this invention is prepared by mixing two agents, fipronil and imidacloprid, in a weight ratio of (1:0.1) to (0.1:1), and can be made into various formulations such as seed coating agents, seed dressing agents, suspension concentrates, powders, and emulsifiable concentrates. The advantages are: its insecticidal effect on the rice stem maggot

How effective is Huoxiang Zhengqi Shui (Agastache Rugosa Qi-Correcting Liquid) in treating a cow's cold?
A draft cow suffered from uninterrupted diarrhea and dysentery due to exposure to wind-cold in winter. The next day it was fed an appropriate amount of charcoal powder, which took effect at the time, but it soon relapsed. On the third day its hair stood on end and its body trembled, and it still had uninterrupted diarrhea; it was diagnosed with a gastrointestinal-type wind-cold cold. Based on an estimated cow weight of 250 kg, it was given 5 vials of Huoxiang Zhengqi Shui, mixed into warm feed water for drinking. Within a few minutes the cow's bowel movements returned to normal, and its muzzle was no longer dry. Also, because the cow had previously been harmed by doufu jiangshui (drinking too much water), and this substance is cold and cooling in nature, Fuzi Lizhong Wan was therefore given at 5 times the human dosage, used for 2 consecutive days, to
