Potato and scallion multiple cropping can achieve two harvests from one field
I. Cultivation of the preceding potato crop 1. Variety selection The potato variety suitable for potato-scallion multiple cropping in the Xiongyue area is "Dongnong 303", with 15 kg of seed used per mu, maintaining 4500 plants. 2. Deep plowing and fertilization In autumn, plow the soil to a depth of 15-20 cm, harrow the soil in spring, and apply 4000 kg of high-quality organic fertilizer per mu as base fertilizer. 3. Seed potato sprouting In early March, place the selected seed potatoes in a greenhouse or on a heated kang to sprout for about 10 days. Cut the seed potatoes into pieces of 20-30 g, and after cutting, air-dry the seed pieces for 6-12 d, then they are ready

How to handle a sick pig that shows no improvement after multiple drug injections
In daily veterinary practice, it is common to encounter sick pigs that have been given multiple symptomatic injections of penicillin, streptomycin, analgin and other drugs without any improvement. We suggest handling the situation as follows: Basic method: calculated per 30 kg of pig body weight per dose (the same below), dexamethasone sodium phosphate 6 ml, nikethamide 2 ampoules, kanamycin hydrochloride 10 ml, each injected intramuscularly separately. If coughing and gasping do not stop, use the basic formula plus 3% ephedrine 2 mg injected intramuscularly. After 10 minutes, inject sulfadiazine sodium 0.5 mg intramuscularly

Detailed Explanation and Application of the New Muskmelon-Rice Multiple Cropping Technique
I. First Crop Muskmelon 1. Seed selection and land preparation: Choose high-yield, high-quality muskmelon varieties with a growing period of about 90 days, such as Chaozhao Tangwang and Hongchengcui No. 1. Before the ground freezes the previous year, plow the paddy field well, harrow, press and form ridges with a ridge spacing of 50-60 cm, and press firmly to preserve soil moisture. Along with land preparation, apply 5000 kg of high-quality farmyard manure per mu. 2. Seedling raising and transplanting: Soak seeds to promote germination in late February, raise seedlings in a greenhouse in late February to early March. You may use seedbed seedling raising followed by pricking out into seedling bowls, or directly raise seedlings in seedling bowls. For planting melons in the main field, transplant the melon seedlings into the main field before April 15.

How to prevent and control cotton seedling diseases? Take multiple measures to ensure strong seedlings
Because rain kept falling continuously during the cotton sowing period and after emergence, this year's seedling death is more serious than in previous years, and the most severe cases have already begun to be destroyed and replanted. 1. Main symptoms After cotton seedlings emerge, yellow-brown lesions appear at the base of the stem (where it meets the soil surface), gradually expand, become sunken and rotten, turn dark brown in color, and the cotton seedlings wither and die. This is typical "damping-off," commonly known by cotton farmers as "black neck" disease. 2. Causes of seedling death 1. Early sowing date and low temperature. According to forecasts from the meteorological department, the temperature in April 2008 was on average

Detailed explanation of year-round production technology for multiple mushroom species in one greenhouse
In 2001, our county began large-scale promotion of white beech mushroom (Pleurotus nebrodensis) production technology throughout the county. The white beech mushroom belongs to the medium-low temperature type of edible fungi, fruiting within the range of 5-20°C. Before fruiting, the white beech mushroom must undergo a low-temperature stimulation process, which determines that the fruiting period in our county is from late November to late March of the following year, causing the mushroom greenhouse to sit idle from April to November around summer, and the biological conversion rate of the white beech mushroom is also relatively low. Starting from 2002, our county began trial

Prevention and Control Methods and Technical Key Points for Common Multiple Diseases in Pigs
The common multiple diseases of pigs mainly include: piglet Escherichia coli disease, transmissible gastroenteritis, epidemic diarrhea, asthma, and piglet hypoglycemia. These five common diseases of pigs seriously affect the normal growth and development of pigs, hinder the development of the pig industry, and often cause massive pig deaths. Therefore, the prevention-oriented policy of prevention and control must be implemented, and careful prevention and treatment must be carried out to take preventive measures, and one must never take it lightly, so as to ensure the smooth development of the pig industry. Piglet Escherichia coli disease Piglet Escherichia coli disease has the following three manifestations: early-onset

How to Handle Sick Pigs That Do Not Respond to Multiple Drug Injections
In daily veterinary practice, it is common to encounter sick pigs that have been given repeated symptomatic injections of penicillin, streptomycin, analgin and other drugs without any improvement. We suggest the following approach: Basic method: calculated per 30 kg of pig body weight per dose (the same below), dexamethasone sodium phosphate 6 ml, nikethamide 2 ampoules, kanamycin hydrochloride 10 ml, injected intramuscularly separately. For persistent coughing and wheezing, use the basic regimen plus intramuscular injection of 3% ephedrine 2 mg. After 10 minutes, inject sulfadiazine sodium 0.5 mg intramuscularly.

Cotton shows disease symptoms, integrated control with multiple measures
Symptom identification of cotton Fusarium wilt and Verticillium wilt. Cotton Fusarium wilt can occur throughout the entire growth and development period of cotton, but it occurs more severely at the seedling stage. If favorable conditions occur, it can also break out heavily at the adult plant stage. Sudden wilt type: leaves suddenly lose water, droop and wilt, leaf color is dark green, leaves become soft and thin, the whole plant dries green and dies, but leaves generally do not fall off, and petioles bend. Yellowing type: can occur at both the seedling stage and the adult plant stage. The yellowing type mostly starts from the leaf margins, with part or all of the leaf turning yellow, and finally the leaf dies or falls off, while the petiole

Pinching Technique for Robinia hispida: Promoting Multiple Blooming Cycles
Robinia hispida, also known as Jiangnan locust, under natural growing conditions blooms only once a year. A large amount of nutrients is devoted to shoot growth, and water sprouts can reach over one meter. When summer arrives, strong winds can blow the tender shoots off their growth direction, forming a lopsided crown. This not only reduces the ornamental value of Robinia hispida but also increases the workload of winter pruning. During winter pruning, many branches that have grown rampant for a year are removed or cut back as useless branches, and the cut-back branches will continue to grow rampant the following year. By utilizing the multiple-growth

Multiple high-yield, multi-resistant, high-quality hybrid japonica rice varieties successfully bred in Tianjin
After several years of research, the Rice Research Institute of the Tianjin Academy of Agricultural Sciences has successfully bred 9 new high-yield, multi-resistant, high-quality hybrid japonica rice varieties. At present, 6 of the new varieties have been designated as nationally approved high-quality hybrid japonica rice varieties, with an annual promotion area of more than 1 million mu, accounting for 20% of the total hybrid japonica rice area in China. It is understood that the Rice Research Institute of the Tianjin Academy of Agricultural Sciences, through independent innovation, successfully solved the worldwide problem of hybrid japonica rice breeding, and was the first in China to establish a hybrid japonica rice breeding technology system and seed production system, raising hybrid seed purity
