To prevent the madness of greenhouse cucumbers, vegetable farmers can adopt the following technical measures:
1. Reasonably dense planting. Greenhouse cucumbers should be sparsely planted, and fertilizer and water management should be strengthened. The density of colonization should be determined according to species, soil strength, and season. Generally, 4000 to 4500 plants are planted per acre.
2 timely watering. Watering should be controlled between the two to promote the middle, that is, before the melon period, to increase the temperature of the soil by cultivating the soil to ensure that the see wet; dry period of water every 7 to 10 days, every watering should be in the pick Before proceeding to control the madness; control the watering after the top melon is harvested and promote new roots. When watering back, it will be watered in time.
3. Reasonable fertilizer. On the premise of ensuring the supply of soil nitrogen, appropriate application of phosphorus and potassium fertilizer. Top dressing is in liquid form, with water as fertilizer. Generally before the root melon vinegar recovery after 15 to 20 kg of urea, potassium sulfate 10 kg, 15 kg of diammonium phosphate, after each harvest two melons chase once fat. In the middle and later period, the water is used to chase the cooked manure for 2 to 3 times, each time about 1,000 kilograms per mu.
4. Control the temperature. The suitable temperature for the growth and development of cucumber is 25°C～30°C, and the growth of plants is faster than 30°C. Therefore, in the hot season, shaders and other nets should be used to cool down.
5. Control humidity. The suitable air humidity for cucumber growth and development is 60% to 80%. When the humidity in the booth exceeds 85%, immediately ventilate and dehumidify.
6. Look to tie the vines. The vine spreads when it reaches about 30 centimeters. At the beginning of the erection of the abduction, when the vines grow vigorously, the kidnappings can be bent around, and the degree of bending and tightness may depend on the growth of the guaguana. If there is a small amount of melons, the degree of bending must be large and it must be tight.
7. Hormones protect melons. After cucurbit cucumber, the vegetative growth of the plant was controlled. Therefore, it is necessary to try to make the first batch of flowers more sitting. If the first batch of flowers sits less, it can easily cause melons to grow mad. In order to make the cucumbers sit on melons, you can use the guava or the flower spray, which can be used in the morning market to increase the early yield and effectively prevent melons from going crazy.
8. Look at what you are collecting. When root melons are harvested later, the growth of melons is inhibited. Crab larvae should pick root cultivars at an appropriate time in order to play the role of falling plague to ease the madness. When the melon grows weak, it is necessary to harvest the root melon as early as possible to prevent falling, and take measures to promote growth as soon as possible.
