Chinese cabbage and radish in time for storage
As the saying goes: "If you don't cut vegetables in the winter, you must be victimized." Cabbage should be harvested in time before freezing, and the head should be aired in the south for 2 to 3 days and then refurbished for sale. If there are conditions, it can be dug and stored for sale. After drying, it is anti-freeze damage. It can be piled up in the round and piled up into the round pile for temporary storage. When the outside temperature is lower than 0 °C, it will be stored again. Radishes and carrots should be harvested before the frost arrives. Twist the tweezers, cover them with tweezers to ensure that they are not frozen and heated, and dig the storage oysters in advance. Store them in the oysters from November 15th to 20th; celery and rapeseed planted in the open field. Ukrainian vegetables, coriander and other leafy vegetables should be harvested in time before and after winter to prevent freezing.
The greenhouse vegetables are well pulled and harvested.
In the autumn greenhouse, tomato, cucumber, pepper, eggplant and other warm crops should be pulled in time, and the immature tomato fruits can be stored in the greenhouse for ripening; for cold-resistant cabbage, spinach, lettuce, rape and other crops to be done Good insulation and cold-proof measures, close the vents and doorways, cover the 1 meter high grass curtain or old insulation around the shed at night, and keep it in time for the best commodity period.
Strengthening cold insulation in solar greenhouse
For the weak parts of the greenhouse doors and windows, the back wall, the rear roof, etc., early insulation and cold protection measures are taken. The rear window and the exhaust fan port are sealed with foam board, straw curtain and other materials; the cotton curtain is installed at the door, and the windshield of 5 meters long is set at the entrance of the greenhouse; the cold weather ditch is filled into the insulation material such as straw and leaves in time. The front roof of the shed is placed on the ground with a 100 cm high agricultural film to prevent cold; the rear roof is too thin to cover 2 to 3 layers of straw curtains or old insulation is insulated; the back wall is made of soil or covered old straw to increase insulation Sex, two layers of agricultural film or non-woven fabric are set in the shed at night.
Warm-temperature vegetables increase light-tolerant cold-type vegetables, batch sowing or planting open roots, leeks, timely pouring frozen water
Greenhouse lettuce, rapeseed, spinach, garnish, cherry radish, fennel, buckwheat and other fast-growing leafy vegetables and root vegetables can be sown or planted in batches to supply the winter market. Spinach, fennel, and cherry radish are directly sown; lettuce, rapeseed, and sauerkraut are taken by means of seedling transplanting. For celery, radish, cabbage, cauliflower and other crops that are in the growth period, it is necessary to manage the suitable environmental conditions, cultivating loose soil, topdressing, watering, and controlling pests and diseases.
For greenhouse plants such as tomatoes, cucumbers, eggplants, sweet peppers, etc., it is necessary to adjust the temperature, light, air humidity and other growth conditions, especially to increase the light, and often scrub and clean the greenhouse film. Light transmittance; timely ventilation and ventilation, strengthen the management of pruning, assisting pollination, thinning and fruit thinning, scientific topdressing, watering, timely control of pests and diseases, etc., to promote plant growth and health, more results, good results.
Over-winter spinach, shallots, etc., wintering root leeks, etc., timely pouring frozen water and cultivating loose soil, and pouring the frozen water at the time of “night freezing and freezing†(ie, freezing at night and thinning during the day) is most suitable. After pouring the frozen water, the ploughing of the soil will be done, and the surface cracks formed by the watering will be tightened to ensure the safe wintering of the seedlings.
Shed room vegetable rushing fertilizer seven attention
First, it is necessary to use a fertilizer that is not volatile or has poor volatility for ground application. The ventilation in the shed is relatively small, it is easy to collect harmful gases, and harmful gas poisoning occurs. Therefore, it is not advisable to use volatile fertilizer for ground application.
Second, the application method should be appropriate. When fertilizing the fertilizer, the solid fertilizer should be dissolved into the water in advance to form a mother liquid, and then applied with water (the organic fertilizer should be sprayed about 10 days before the application of the organic fertilizer, and the supernatant is taken with water). Do not directly spread the fertilizer, and then water the application, so as not to cause uneven fertilization, local concentration is too high, rooting occurs.
Third, the concentration of fertilizer solution should be appropriate. The amount of watering for flushing is generally large, and the fertilizer is highly diluted when fertilizing. If the amount of fertilizer is insufficient and the concentration of fertilizer is too low, the fertilizer effect is poor, and the effect of fertilization should not be achieved. If the amount of fertilizer is too large, or the amount of watering during fertilization is insufficient, causing the concentration of fertilizer to be too high, rooting is prone to occur. . For volatile fertilizers, when the concentration of the fertilizer is too high, the amount of harmful gases volatilized into the air is relatively increased, and the chance of harmful gas poisoning increases. Generally speaking, when watering according to the normal watering amount, the solid fertilizer can be applied according to about 120% of the conventional ground application amount. After the liquid fertilizer is mixed with the fertilizer liquid, the water is slightly turbid. The special flushing fertilizers currently on the market can be carried out according to the instructions.
Fourth, the amount of water should be appropriate. When fertilizing, it is not advisable to flood the water to avoid or reduce the loss of nutrients in the fertilizer. However, it is not possible to water too little to prevent the fertilizer from being too high in concentration. The specific amount of watering should be determined according to the type of soil, the type of cultivated alfalfa and the period of cultivation of the vegetables. The suitable amount of watering is that the water can wet the soil in the main distribution area of ​​the root system after watering. After watering, the wooden stick can be inserted into the ground to check the moisture of the soil layer to determine the appropriate degree of watering.
Fifth, pay attention to balanced fertilization. Some farmers' friends have identified a kind of fertilizer and used it as a "universal fertilizer" for regular application. As a result, too much single nutrients are caused, causing physiological diseases of vegetables. The correct method is to apply balanced fertilization according to different growth and development stages of vegetables, and apply various fertilizers alternately.
6. Pay attention to prevent gas damage after fertilization. In the winter, the shed is closed for a long time. If the ventilation is not paid attention to after the fertilization, the shed will easily accumulate harmful gases, which will cause gas damage to the vegetables. Therefore, in the winter when the cloudy days should pay attention to avoid using unfertilized chicken manure, fertilizer with high nitrogen content, etc., can apply bio-organic fertilizer to strengthen the roots. In addition, when the topdressing of vegetables needs to be topdressed in the middle and late stages of growth, it is possible to choose a sunny morning and a small wind after topdressing. In the event of gas damage, it is necessary to take remedial measures in a timely manner: First, loosen the soil in time, strengthen ventilation, and let the harmful gas shed the shed as soon as possible. Even the cloudy day should be properly ventilated, put it in the morning and evening, put it at noon, or put it at low temperature. Large at high temperatures. The second is to spray plant growth regulators to promote the recovery of the affected crops as soon as possible.
Seven, flush fertilizer should not be used. Fluctuating fertilization and over-expansion will cause unfavorable phenomena such as soil compaction, roots and wilting of vegetable greenhouses. The main fertilizers are nitrogen and potassium fertilizers, with less phosphorus, and trace elements such as calcium and magnesium are extremely low. Equilibrium; the effect of fertilization is limited to the surface layer of the soil, and the film is covered. The temperature in the shed is relatively high, and the surface roots are large. If you encounter low temperature and cold current or apply some inferior fertilizer, it is easy to burn roots and cause rotten roots. . In addition, the abuse of fertilization can lead to long vegetables, degraded quality, reduced fertilizer utilization, and increased salinization of greenhouse soil properties.
