Heading above: keep the leaves luminous, keep the optimal folic state and achieve high quality production, title: chicken drop technologies: longer-long-longer vegetables, text:
In the management of vegetable production in greenhouses, chickening is one of the important technical measures for the long-term growth of greenhouses ' vegetable production and high quality production. In order to help growers become more aware of the availability of chickening technology and apply it to production management, the current facility agriculture topic has been combing the relevant technology for a wide audience。
Understanding the role of the chicken
The role of the chicken
Roasted chickens provide high-quality, high-quality, high-quality, medium- and long-lived vegetable varieties that are growing with high-yielding growth. The chickens allow the leaves to be distributed evenly, maintain a reasonable light position, maintain optimal folic state, and increase light efficiency while facilitating farming operations。
Time for chicken
When the plant grows near the roof of the shed and removes the yellow and ill leaves from the lower part, the chicken must fall in time when it is above 30 cm above the ground. The chickens are chosen for the summer, when they have low water content and soft tissue, and do not fall in the mornings, mornings, evenings and after watering, to avoid and reduce the damage to the chickens。
Preparations
Water control. It would be preferable not to water 7 to 10 days before the chicken drops in order to reduce the amount of water in the chicken tissue and increase its resilience。
Reduce the source. An old yellow leaf should be removed from the lower part of the penis prior to its disappearance and taken out of the shed and buried or burned. The fruit of the site must also be fully harvested so as to avoid the emergence of a humid ground of leaves and fruit that form the centre of morbidity。
Technical requirements
The leash around the chicken. And lay loose the rope around the penis, and lay it on the ground, and do not pull hard. The empty chickens shall be in the same direction in an orderly manner, and they shall be gradually receded on both sides of the planting. When rounding the penis, bend the penis along the bend, do not bend hard or in the opposite direction, avoiding a break or a break in the opposite direction. At the beginning of the tubing, the length of the faller is short, the length of the circle is small, the length of the length is slightly longer, the length of the length is large, and the length of the faller is one third to one quarter。
Leave a few leaves and a few leaves. Maintaining a length of 15 centimetres from the aluminum, with more than 15-20 pieces of leaves per plant and a height of about 1. 5 metres。
After the chickens
Temperature. In the days following the fall of the chicken, the temperature of the greenhouse will be increased appropriately to facilitate the rapid healing of the injured penis。
Spray. In order to prevent the invasion of the fungus from the chickens and blades, it is used to spray the disease, depending on the type of crop, the season and the frequency of the disease。
Fat water. Despite reducing the location of the results of the plant, chickens are unable to reduce the physical distance between the area of the result and the root line, and the increasing availability of nutrients, such as insufficient supplies of fat water, can result in poorer quality outcomes. Sufficient fat water should therefore be supplied to meet the demand for plant-based reproduction。
Whole branch. When the chicken falls, the side branches issued by the secretary of state shall be removed in time to ensure the nutritional supply of the master。
What about the cucumber chicken
How to determine when the cucumber drops
In the case of greenhouse cucumbers, cucumbers should be treated in a timely manner when they reach the height of the cucumber plant to the point of touching the wire or exceeding the normal height of the farm management operation. Under normal conditions, cucumbers are cucumbers when the amount of cucumbers is about 1. 6 metres high and above
Best time to drop a chicken。
However, the timing of chicken landings cannot be general or blind, and the timing of chicken landings should be determined flexibly in relation to the actual growth of cucumbers. If a cucumber plant is relatively weak, it should be flexible to delay the fall of the chicken, and it is recommended that it should first be reinforced by the pursuit of fertilizing water and that it be delayed to about 1. 8 metres. In the case of cucumber plantations in the fallure period, which overlap with long, long, side-leaved leaves, cucumbers should be cucumbered well in advance, and it is recommended that the cucumbering period be moved from 1. 6 to 1. 5 metres。
Cucumber chicken
What's the problem
Water should be managed fairly before and after the fall. Avoiding watering during the 3-5 days before and after the cucumber drops, can reduce the water content of the penis, increase its softness, and prevent its breaking. Water management in the wake of cucumber chickens can be used to avoid the wetness of the soil in the field, the causing of various types of highly humid diseases, the slow healing of the chicken wounds and the infection of the wounds by the disease. In addition, the use of urea-like nitrogen fertilizer should be avoided within 3-5 days of cucumber chickening。
Reasonable selection of the chicken season. The cucumber-down chicken should be chosen in the middle of the sun, not in the rain, not in the morning, not in the morning, and not after watering the cucumber-down field, because the water content of the cucumber-dang is low and softer, and it is not easily sprained or fractured during the fallout, otherwise it will affect the growth and flowering of the later part of the cucumber。
Combining leaves is reasonable. When cucumbers grow to the end of the medium term, some old yellow leaves and pest leaves appear in the lower part of the plant. In order to reduce the inefficient consumption of the nutrients, the nutrients are concentrated in the development of flowers, and when the family grows chickens, they are combined with the removal of old yellow leaves and sick leaves. It should be noted, however, that cucumbers are generally carried out in the order of first leaf and then chicken, with a focus on removing the lower part of the plant, which has lost the old, dead, yellow, sick and overlapping leaves used to produce radiant co-operation. The removed blades are to be cleaned out of the field in a timely and thorough manner and treated in a concentrated and deep burial. In general, when picking leaves before falling, it is necessary to ensure that 15 to 20 strong leaves are left on each of the strains and that the leaves selected on the strain are evenly distributed. In addition, when cucumbers fall into chicken, new side branches, curls, male flowers, pests and deformities should be removed as soon as possible and in time。
Flexiblely adjust the height of cucumbers. In the case of cucumbers, there may be high, low, strong and weak strains. In order to ensure that the head of the chicken is well organized and grown, it should be adjusted flexibly to the different cucumbers ' actual strength. For strong and long cucumbers, it is possible to diversify and control the length of the penis, but for those that are weak and low, the cucumber should be cucumbered, as appropriate, so that the weak plant can grow as soon as possible。
(c) reasonable regulation of the tightness of the ropes. Whether it is a cucumber or a chicken, it should be properly regulated when it is tied to a cucumber. On the one hand, the upper end of the rope should be tied tightly to prevent the fall of the penis as a result of the cucumber's continuous outcome, and on the lower end of the rope should be moderately relaxed, leaving room for the main man to grow and grow thick, in case the main man of the cucumber is strangulated or strangulated as he grows. On the other hand, with respect to the growing and weaker cucumber plant, it is recommended that a straight-up, loose-tie approach be adopted, which would facilitate the growth of the weak plant as soon as possible. In the case of larger and more dynamic cucumber plants, it is suggested that a curved, tight-lined approach could serve as a deterrent。
Timely protection of wounds and prevention of illness. In order to protect the wounds from disease-infested bacteria during the chickening and leaf removal process, cucumber gardens are sprayed in a timely manner with wide spectrogen microbicides, such as polybacterium, bacillus and copper formulations, and quarantine and protective treatment of the wounds are performed。
