During the summer, hot and rainy, silkmelons are prone to problems such as bending, deforming, diseased and low commercial rates. The tradition is free to grow by the silk melon, which is subject to uneven light and leaves are bent and sold at reduced prices. The melon re-emergence technology is a practical programme for low-cost upscaling of production, coupled with standardized thawing, hydro-fertilization and precision planting of pests and diseases, which can effectively reduce deformations, smooth greening of the melons, increase the commodity rate and extend the harvest period. The system describes the physical exercise process, the supporting field management, the high-prevalence pest identification and control programme。
I. Technological principles and core advantages of spinach rewinding
1. Rationale
The silk melons have gravity-oriented growth properties. Conventional natural growth, with the side of a melon fully lighted, side-stained, growing at inconsistent rates and prone to bending; the melons are exposed to vines, leaves are squeezed and deformities are exacerbated。
Back-to-back operation: the cucumbers that have just been sitting are fixed up, and the cucumbers naturally grow up vertically. The gravitational gravitational strips are used to balance growth speeds on both sides, avoid foliage and crushing, so that light is visible on all sides, and the strips are straight and clean。
Main strengths
1. Improvement of the fruit shape and increase of the purchase price: a substantial reduction in the number of bends, deformities and an increase of more than 30 per cent in the number of commodities
2. Ventilation and reduction of the disease: lasagna do not carry leaves to reduce the occurrence of frosting, anthrax and scavenging
3. Straight transmission of nutrients: vertical growth reduces nutrient consumption and faster expansion of the melon
4. The ease of farming operations: the use of drugs, harvests and utensils in order to save time
Reducing the risk of pests: lasagna, reducing the probability of harm for snails, snails, guacamole flies and guacamole。
Ii. Standardized earthwork techniques for spinach rewinding (generalized in daejeon/boom)
(i) pre-element: chowing, bottoming (reverse)
1. Literary requirements
It is proposed to use a high-season hanger at a height of 1. 8 metres, with a barbed wire fence and a staff frame. The vines are spread evenly on the shelf to avoid the foliage。
2. Whole-of-the-art management
- elimination of all sprouts and branches below 50 cm of the main chicken and the concentration of the feeding of the main chicken
- when the main chicken is on the shelf, the strong chicken is kept in excess of 10 knots and the weak branch is cut off in time
- one melon on each side and two or three functional leaves on top
- the timely removal of twigs, yellow leaves and sick leaves and increased ventilation
- plumbing: the removal of deformed females, excessive larvae, and the prevention of premature fall and fall。
(ii) rewind best operational timing
Female pollination is completed and the cucumbers grow up to 5-8 cm (bold fingers)。
It is premature: the cucumbers are too young to be strangulated; it is too late: the cucumbers have begun to bend and their effect has deteriorated。
(iii) three ways of doing it backwards
1. Rewinding of simple ropes (preferred to by farmers)
Use soft cloths, plastic bandages, cotton lines, softly tied to a melon handle (where the flower is located), fixed to the upper fence, and naturally emptied vertically。
Focus: ties cannot tighten the handle, leave space for growth, and prevent scavenging and scavenging of the melon from causing decay。
2. Web-based piping
The mini-soft network holds the upper end of the guacamole, with the ropes hanging over the shanty, without any harm, and suitable for long-line cultivation。
3. Pack + upside-down combinations (prefective silk melons)
Upon completion of the back-to-back, the melons are given a swivel-free bag, while the melon flies and sun spots are protected to further improve their appearance。
(iv) backward management attention
1. High temperature does not work at noon and opts to reduce the infection by 9 a. M. And after 4 p. M.
2. A wind weather check to check the ropes in order to prevent the disguising of the pickles resulting in the fall of the melon
3. Continuous observation of the growth of the melons and detection of the timely release of the ropes embedded in the melon handle
4. Severe deformities and the direct removal of the sick and sick, and not to be forced upside down and waste of nutrients
5. Roast and trim to avoid the rainy weather and reduce the risk of infection。
Iii. Polio management (inflating, preventing premature decay)
1. Sitting in front of a melon: control of nitrogen fattening, increase of phosphorus fattening, avoidance of the use of melon by vines and vines; application of potassium phosphate + boron fat on the leaves to promote female division。
2. After the first rewinding of cucumbers (critical period of expansion)
Pouring of high potassium water soluble, in small quantities, once in 7-10 days
Leaf formulation: potassium dihydrophosphate + sequestering to prevent fibrous, umbilical, premature decay。
3. Water management
The silkmelon is wet but the soil is wet; it is so hot and dry that it is not allowed to overflow at noon; and it is drained in a timely manner after the rain, with oxygen-deficit root causes of corruption and disease。
Rewinding plants produce large amounts of evaporation of melon bars, and persistent droughts are prone to melon wrinkles and timely recharge of water。
Iv. Programme for the identification and prevention of illnesses in the ribbon
1. Froscilosis (hot, high-wet, no. 1 disease, leaves, piercing)
Symptoms: there are irregular spots of yellow and brown on the leaves, grey and black corrosive on the large back of the wetness, rapid onset of disease, resulting in insufficient photocolumn and thinness of the melon。
Prevention: rotation of esters, propsenzig, dyson manganese zinc
Treatment: fluoroethylene ketone, frosted manganese zinc, cascadium, black tubing combination, 7 days, 2 consecutive times。
2. Anthrax (harming leaves + guacamole, creating dents)
Symptoms: brown dents on the melon face, decomposition of the melon at a later stage; round brown spots on the leaves. Rewinding can significantly reduce ventilation。
Pharmacy: ethylene acetate, ethodeol, meshamine, mesmeric combination, haze; drug rotation to avoid resistance。
3. Epidemic diseases (cranium, rotten melon, rotting water)
After high temperature rains, the chicken cortex shrunk and the larvae quickly softened。
Precautionary: athrax, densen manganese zinc; early onset: fluorine, fungus ketone manganese zinc, black tubing。
4. Pinky
The leaves are covered with white powder, which hinders light co-operation and the planting of plants。
Pharmacies: ethylene ester, ethyl, ethylenephenol sulfate, methacone combination, haze。
5. Decay
The staves, fluids, gradually dried up, causing the whole strain to decay。
Formulation: ethylene acetylene + esters, with a focus on root root。
6. Virus disease (aphids, lice transmission)
New leaf wrinkles, deformations, small sittings, twisted bars。
Control cores: pre-treatment of insects; pharmaceutical agents: amino-vagina + zinc fertilizer, viral vitro, increasing resistance of plants。
V. Main pest identification and precision medicines for melons
One, the guacamole
The larvae eat the melon, the leaves, which cause the melon hole to rot。
Prevention and control: chlorine benzomide, methachlor, best applied in the evening。
2. Gorgeous flies (muggles, commercials are dead)
Insects lay their eggs on the skin of the larvae, inside the larvae, and the larvae smelts。
Integrated programmes: cedar booby traps; pharmaceutical agents: bromocythylene, ethylidoccicides; co-opt + packs, significant increase in effectiveness。
Three, aphids, pink lice
Sorrowing fluid, spreading viral disease。
Pharmacies: furflammide, amphetamine acetone, fluoridamine, white flying combination。
Four, the horse
It endangers young, ferocious, rough scars on the skin。
Pharmacy: excretion, equidoxin + aphidium。
5 red spiders
High-temperature drought erupted and leaves lost green and white。
Pharmacy: acetamide, acetamide (filled) and squirming of the leaves on their opposite sides。
Vi. A full-time programme of retreading melons
1. Roast length (prevent disease + pest control)
Package: zinc + furanamine + potassium phosphate
Roles: prevention of disease, eradication of early aphids and promotion of thawing。
Ii. Initial repositioning of cucumbers (key melon periods)
Package: bacillus ester + ether acetate + methaline + 硼钙 leaf fat
Impacts: prevention of anthrax, carcasses and guacamole, reduction of deformity and promotion of expansion。
3. Ongoing harvest period (7-10 days round, drug rotation)
Disease prevention: exchange of dyson manganese zinc/polymer ester
Rotation of pests: rotation of chlorflammide, equidoctoxin, furachlor。
Vii. Practice of application (focus on back-to-back cultivation)
1. The spray must be equilibrated on the opposite side of the leaf and on the top and down of the bar; the plume is suspended and the liquid is more easily covered
The summer heat avoids the application of 11 p. M.-15 p. M. To prevent the burning of melons and the formation of plasters
3. Precise the use of emulsifiable concentrates for guacamole, which can easily induce melon lacquers; preference is given to suspension and water dispersion particles
Multi-pharmaceutical amalgamation is based on the principle of “diplomatic dilution” and does not randomly mix various types of cream
5. Strictly observe the pesticide safety interval before harvest
6. Timely application of protective microbicides after the rains to prevent outbreaks of disease as a result of storming。
Viii. Common error alarms
1. Not all silk melons are suitable for rewinding: too short a corrugated melons have the same effects and the most visible effects are the long wires, the fragrance melons
2. Insistence and incorruptibility of the branches: the leaves are constricted, the disease erupts and the deformity continues to spread
3. Overstretching: swelling, strangling, falling, rotten
4. Nitrogen overweight: vines and vines are long and sit low, even if they are hung upside down, and the bars grow slowly。
