I. Seed pre-processing
Before sowing, it is necessary to shell the seeds in the sun and choose the sunny morning. Spread a thickness of 10 centimeters or so, flip once every 1 to 2 hours, and dry for 2 to 3 days. Peeling time is preferably 10 to 15 days before sowing. After shelling, the seeds were large and neat, the grains were full, and the color was good. There were no primary and secondary large grains for mechanical damage, and three small grains were eliminated.
Second, soil preparation, deep plowing
Peanuts are the crops that bloom on the ground. The roots are well-developed, and the soil is required to be deep, so it must be plowed deep in the winter or early spring. For clay soil, appropriate amount of fine sand can be added to improve the permeability of the resulting soil layer. For the thick layer of sand, the result was deep-turned, and 10-15 cm thick clay was pressed under the plow to create a soil for water retention and fertilizer conservation.
Third, ridging fertilization, cultivation of land
Due to the low number of nodules in the early stage of peanut growth and the weak ability of nitrogen fixation, the fruit needles in the middle and late stages have been buried and should not be fertilized. Therefore, it is very important for peanuts to apply sufficient basic fertilizer. In general, the combined ploughing and soil preparation before sowing, one-time application of basal fertilizer to meet the fertilizer demand during the whole growth period. Conditions apply as much as possible farmyard manure, mid-production land per acre applied farmyard manure 2000 to 3,000 kilograms, 45% compound fertilizer 30 to 40 kilograms, boron fertilizer 1 kilogram; high-yield fields per acre end of farm manure 3000 to 4000 kilograms , 45% compound fertilizer 40 ~ 50 kg, boron 1 ~ 1.5 kg. In addition, peanuts do not advocate the application of seed fertilizers, especially when boron fertilizer is used as a base fertilizer, it is strictly prohibited to apply into seeding trenches and avoid burning seedlings.
Fourth, appropriate sowing, seedlings and seedlings
When the ground temperature of 5 cm soil layer is stable at 12°C, it can generally be half a month earlier than bare soil cultivation. April 20 to May 5. Two rows of large ridges, 16 to 18 cm from the hole, 8000 to 10,000 holes per acre, 2 sowing per hole; 3 to 4 cm deep.
V. Field Management
In the early stage (seedling stage), management should be strengthened, good roots should be established, pests and diseases should be prevented, and early-onset seedlings should be promoted.
Mid-term (flower needle-result period) is mainly to control the growth of the upper branches and leaves, promote the development of the following fruit needles and young fruit.
The later period (maturity period) is the period of filling of kernels with enlarged kernels, which mainly embodies the words “post-protectionâ€, focuses on the drought-relief and anti-rotting fruit, treats the insects with high yield, and prevents disease and leaves to promote fruit filling.
VI. Pest Control
Peanut leaf spot: Spray the following low toxicity fungicides before starting flowering, or use 70% mancozeb wettable powder 70-80 grams per mu, 400-600 times liquid, or use 50% thiophanate-methyl wettability Powder 70-100 grams per acre, 1000-1500 times liquid, optional one.
Flower rust disease: At the beginning of the disease, 75% chlorothalonil WP can be used per acre for 100-125 grams, and 60-75 kilograms of water can be sprayed. Or Bordeaux spray with a 2:2:200 ratio of copper sulfate, quicklime, and water. In severe cases, two fungicides are used alternately and sprayed once every 8 to 10 days.
Peanut root rot disease: Banned peanuts for planting. After sowing before sowing, 500 to 1000 grams of 50% carbendazim WP is applied per 100 kg of seed.
蛴螬: In July, 50% phoxim or 90% trichlorfon was used to irrigate the roots 1000 times.
Peanut meal: 50% anti-inflamy WP per acre 10 to 18 grams, watered into 2000 to 2500 times liquid; 40% Dimethoate 50 ml water 60 kg, dubbed 1000 to 1500 times liquid.
Gastrointestinal Tract Infection
Gastrointestinal tract infection
There are many kinds of intestinal diseases with complex causes, which have caused great harm to aquaculture production.
Porcine enterovirus infection, rotavirus infection, porcine proliferative bowel disease, Yersinia disease, porcine epidemic diarrhea, porcine colibacillosis, porcine Clostridium enteritis.
Bovine enterovirus infection: the main gastrointestinal diseases in cattle breeding are esophageal infarction, anterior gastric atony, rumen gas (commonly known as bloating), rumen food accumulation, traumatic reticulogastritis, omasum obstruction, Gastroenteritis and pericarditis.
Gastrointestinal infection in sheep: endometritis, mumps, pharyngitis, esophageal obstruction and salivation.
