Cucumber is a vegetable crop that can be grown all year round. It can be cultivated in an open field at moderate temperatures, and can be cultivated in different ways during the low temperature stage. Due to the different levels of cultivation among different households, some cucumber plants grow well in nutrition and can produce few fruits, but the yield is not high and the efficiency is not good. One of the important reasons is that the proportion of female flowers is less. In order to promote cucumber multi-fruiting, large melons, high yield and high quality, summarizing local production practices, agricultural and chemical methods can be used to increase female flowers. The methods are as follows.
First, use fine varieties every other year. Optional part of the seeds for good storage for one year for seeding.
Second, adjust the cucumber dendrite plant type. When the main vine of cucumber grows to 25 leaves, it can pick the main heart, that is, topping, and the side vines can produce melon varieties. When the lower leaves grow to about 30 days, some old leaves are picked. More female flowers can be produced.
Third, optimize fertilizer application technology.
Cucumber grows in the neutral soil more prone to female flowers, increased organic fertilizer can neutralize the acidity of the soil and promote female flower differentiation. The carbon dioxide released by organic fertilizer during the decomposition process is also conducive to multiple female flowers. At the same time, the application of new fertilizers can also effectively promote the growth of female flowers. The first is the spraying of Huimanfeng Active Liquid Fertilizer, and 50 kg of water in 100 ml per mu can be activated. Soil can promote the balanced supply of nutrients in cucumber plants, which is beneficial to multiple female flowers. Second, spraying chemical fertilizer, 100 grams per mu water 50 kg, can stimulate the growth of female flowers in large quantities; Third, spray photosynthetic fertilizer, inhibit Photorespiration consumes nutrients and promotes the growth and development of female flowers. 200 grams of powder can be used per mu, 80-100 kg of water, or 200 ml of liquid fertilizer and 25-30 kg of water.
Fourth, adjust the light, add carbon monoxide. Cucumbers are short-day crops. Absorption of carbon monoxide can alkalinize cell contents and can significantly increase female flower proportions. Therefore, when cucumbers are cultivated in greenhouses, shades can be used to adjust the number of hours of light exposure during sunny high temperatures. When it is continuously on cloudy days, female flowers are more likely to be produced. At this time, fertilizer and water management should be particularly strengthened to increase the rate of seated cucumbers. When it is found that there are not many female flowers in the greenhouse, incomplete combustion can be performed with coal or a little firewood in the shed, and carbon monoxide can be added. However, the time is short and the amount of smoke is diluted to prevent smoke.

Shiitake is known as the "Queen of Plants" and is rich in amino acids and a lot of nutrients that are good for the human body. According to analysis, every 100 grams of fresh mushrooms contain 12 to 14 grams of protein, which is far more than the protein content of ordinary plant foods. In addition, it is an excellent source of calcium, phosphorus, iron, zinc and other micronutrients.
