Stingless micro cucumbers, also known as Dutch cucumbers, generally start harvesting in October, and the proper management harvest period can be extended to 2-3 months of the following year, which can be used for the New Year's Day and Spring Festival markets.
First, temperature management
When the average daily temperature drops to 16°C, the membrane is buckled. After the membrane is trapped, the room temperature rises. Attention should be paid to ventilation, air exchange, and humidity removal during the period. The temperature control in the early stage should not be too high, keep it at 25°C-30°C during the day, 13°C-15°C at night, and 20°C-22°C at cloudy days. When the average ambient temperature drops to 12°C-14°C, insulation measures should be taken, such as Cover grass and so on. In winter, the temperature is controlled at 23°C-25°C during the day and cannot exceed 28°C. The minimum temperature is controlled at 12°C-14°C in the morning and the temperature can be lowered appropriately in cloudy days.
Second, water and fertilizer management
In the early stage of melon harvesting, the outside temperature was relatively high. Generally, the water was poured once every 10 days. After that, the temperature was lowered and the water was poured in about 15 days. Every 1-2 ounces of water is topdressed with fertilizer, and 100-200 kg of decomposed organic fertilizer or 10-20 kg of diammonium is used per acre. It is better to use the two alternately, so that the quail can be kept until the following February-March 2-3. The melon period should also be matched with foliar fertilizer. Generally, 0.2% potassium dihydrogen phosphate solution can be sprayed and combined with carbon dioxide gas fertilizer.
Third, hang vine, pruning management
The thornless micro cucumbers began to hang when the plants grew about eighty-nine leaves and stems around 40 centimeters. In terms of plant adjustment, single branching and branching of 2-3 vines, that is to say, all the lateral branches below the 7th section of the plant were removed, and more than 8.2 branches of the lateral branches were retained after more than 7 knots, when the side branches reached 10-12 knots. Tips, the main vine when the top of the 22-25. In order to prevent the roots from falling, one should be reserved when the root melons are more, and the rest should be removed. In the process of growth and development, some varieties of micro-cucumber often show a section of two melons or a section of multiple melons, which shows that reproductive growth is stronger than vegetative growth. Fruits and vegetables should be thinned to regulate the vegetative growth of plants. Balance with reproductive growth.
