The chayote has a long growth period. It is cultivated in the early spring in the north, the frost is finally planted on the ground, the flowers are seen when the heat is applied, and the results before and after the white dewfall are harvested before the thick frost. Chayote vines are highly branched and spread, and their descendants are numerous. As long as the water is full, the children and grandchildren will see leaves and melons, and there will be few opportunities.
The technique of northern cultivation of chayote is as follows.
1 In order to raise nests for the winter season, three 60-square-meter octopus nests with a width of 1m were dug on the ground. Within 70 cm of the lower layer, apply 50 kg of human urine or earth-fertilizer, or 1 kg of compound fertilizer and mix with the soil to allow it to fully decompose. The upper layer is covered with 30 cm of soda or soil in the middle of the forest, and it will be cultivated for the next year.
2 Priming Seedling (a) Three methods of simple and germinating seedlings of Northern Chayote: - It is a kind of germination and seedling raising in sweet potato kiln. The temperature in the sweet potato kiln in December is 8 - 10 degrees Celsius, which is suitable for the heat preservation and germination of chayote; Second, it is the germination and growth of vegetable greenhouses. The temperature of vegetable greenhouses in winter is 15 - 30 degrees Celsius, which is the best temperature for chayote's germination. In the middle and late January of the month, the seeds will be transplanted into the shed to germinate. When the germs grow fibrous roots, planting in the shed, breeding Planting chayote in the shed in October to plant seedlings directly on the shelves, early flowering and squashing, spring sheds in spring, early May to early June in Kuching City, and the third is to raise the seedlings in the heating room, choose - In a normal heated room, nursery pots, flower pots or wooden boxes are used to maintain the seedlings. The room temperature is maintained at 15 - 25 degrees Celsius. (b) Intensive embryonic nursery. When the embryonic fetus grows well, when it starts to take root and shoots, gently pull the seed melon suture, use a sterile forceps to move the embryo, gently remove it, and plant it in a small nutrient bowl or in a nutritious soil with good seedlings. (c) Cluster bud cutting seedlings. - A chayote can grow many cluster buds, ranging from two to three seedlings, and as many as six or seven seedlings. These cluster buds can grow to about 10 cm in April and May.
3 Set up scaffolds (a) to lay 2.5 to 3.0 meters of flat or arch corridor scaffolds; (b) Orchard sets of chayote can be borrowed from grapevines, apples, and other types of canopy. The trees are stretched; (c) The courtyards are connected to each other according to the natural conditions of the walls and bamboos; (d) The melons at the top of the tower are only 1 meter high. Regardless of any scaffolding, the main vines of the Chayote only remain - two, to promote the growth of offspring, increase production.
4 Strengthen Water and Fertilizer Management Chayote seedlings planted in the soil in the early spring in Guasuo Su, insisting on watering around the roots every day to keep the ground moist. Seedling period must not rely on melon body fertilize urine to prevent burning seedlings. When the main vine grows to about 1 meter, open the ditch at a distance of 30 cm from the guajava seedlings and apply a small amount of human waste, soil fertilizer or chemical fertilizer. Into the dog days, every 10 days under the flood irrigation racks, with the human body excrement and compound fertilizer, tapping vines, hot weather, pay attention to leaf spray, both cooling and increase leaf fertilizer. After the beginning of autumn, the leaves were sprayed once every 10 days.
5 Timely storage of preserved melons During the early period, melons growing for 15 days should be harvested in a timely manner. Picking melons should be done lightly and gently. People should put them in the room at about 5 degrees Celsius after winter so as to avoid freezing damage. As long as they are properly stored, the melons harvested in September and October can be stored for 7 - 8 months.
6 choose to stay in the melon can be selected in the 3rd and 4th pick melons. Chayote growth period is more than 25 days. The melons should be selected as the sutures of the melon body, and the arches of the two fingers should be highlighted with yellow and green colors. The selected melons still need to prevent warming and early budding before winter.
Cultivation of Northern Chayote
Chayote in the country of origin and southern China's warm and humid climate conditions, the underground roots will not die in winter, renewable vines in the spring of next year, flowering results, can be continued for more than 3 years, and in the north from the south's perennial become - annual. Planting in the northern open field - annual chayote is feasible, suitable temperature from the nursery to the growth period of 20 - 30 degrees Celsius. The growth period has a large demand for water and fertilizer, moisture resistance and yin, not drought, but it is also not resistant to waterlogging. Due to the developed root system of chayote, it has strong adaptability to soil, fertile soil and deep soil layer. Well-drained sandy loam soil cultivation is more conducive to root development.
