With the increasing demand in the market in recent years, the effectiveness of growing cucumbers is good. The average grower has about 5,000 kilograms of cucumber per mu, and Zhang Minghua of Dongba Town, Binhai City, Jiangsu Province has planted cucumbers for 7 years at 7500 kilograms per acre, and the maximum mu yield can reach 10,000 kilograms. In fact, Zhang Minghua's cucumbers are similar to other types of melons in selecting soils for cultivation, fertilizing and controlling insects. The difference is that he has done fine on three links. Specific experience is:
One is to recapture three stages of childbirth. Seeds are sown at the end of December each year. Select early-maturing varieties that are resistant to low temperature, low light, and low melon stage, which are dense in code and resistant to disease. Before sowing, the seeds were first sterilized with hot boiled water at a temperature of about 50°C for 10 minutes, and the seeds were continuously stirred to prevent scalding. Then soaked in warm water of about 30 °C for 4 to 6 hours, washed away the seed film picked up and drained, sown in greenhouses, greenhouse temperature is generally controlled between 25 °C ~ 30 °C. Followed by their own nutrition group or buy a special nutrition cup. The ratio of nutritional groups is 6 to 7 parts of fertile disease-free soil, 2 to 3 parts of decomposed cow (sheep, rabbit) manure, and 1 part of decomposed cyclization. After mixing, add 15-30 kilograms of pig manure or chicken and duck manure per cubic meter of fully roasted and finely sifted, 0.5 to 1 kilograms of phosphate fertilizer, 5 to 10 kilograms of plant ash, and 80 grams of 50% wettable carbendazim powder. Evenly. Put a seedling bud in each group or cup when sowing, and put it in the greenhouse or in a small shed to raise the seedlings. The temperature should be 22°C to 28°C. The third is to wait until the cucumber seedlings grow to two leaves and one core and begin transplanting and planting. The greenhouse is planted with about 2,200 litters per mu, and each litter is put into a group (cup). It is best to transplant in sunny evenings. Do not carry out bad weather with low temperatures and low temperatures. Otherwise it will be difficult to survive. Pay attention to protecting the root system in order.
The second is stressing cultivation of vines. In the vine extension, the following parts of the scaffolding are generally free of branches. In addition to the rest of the trunk, all the buds must be erased. After the cucumbers are climbed on the shelves, they are tipped, leaving two to three robust branches for their development. Cut it all. Because bearing cucumbers will increase the burden on the vines, more foliage will reduce the light and permeability of the base of the cucumber, affecting the whole vine growth and cucumber yield.
The third is to change the land for melons. Continuously grow cucumbers up to a maximum of 3 years. Since continuous cropping will inevitably leave no bacteria, it will be difficult for cucumbers to resist. Every year they use those drugs to prevent and control those similar pests. These pests will produce resistance to insecticides. The use of pesticides will be difficult to achieve and the high yield and stability of cucumbers cannot be guaranteed. .
