Out-of-season planting techniques of balsam pear

Balsam pear is a kind of vegetable loved by consumers, its market season is summer, and with the continuous expansion of its market demand, in order to meet the needs of consumers in different seasons, so out-of-season planting has become the choice of farmers. So how to plant balsam pear out of season? Let's take a look at it with the editor.

1. Select improved varieties

Balsam pear itself is on the market in summer, so it has strong heat tolerance, but weak cold resistance, so out-of-season cultivation is the first to choose cold-resistant, low node position, mainly to the main vine melon varieties. For example, Hanzhong Changbai, Zidu 4, Yunnan Dabai balsam pear and so on, the melons of these films are straight and long, and the disease resistance and stress resistance are relatively strong, so they are suitable for out-of-season cultivation.

2. Cultivate strong seedlings

Off-season can choose to plant in winter and spring, and the temperature is generally low in these two seasons, so it is necessary to use greenhouse hot hotbed to raise seedlings. Because the balsam pear seeds have a thick shell, hard texture, and germinate very slowly at a low temperature, you can scald the seeds with warm water of 50-60 degrees before sowing, and keep stirring until the water temperature drops to 30 degrees, then soak them for one night, then put them in the environment of 30-35 degrees to promote germination, wash them with warm water once a day, drain them and continue to germinate, usually sprouting in about three days. Because

The seed coat is thick and the germination is irregular, so the first germinated seeds should be picked out in batches, wrapped in wet towels and squatted at low temperatures, and sown after most seeds germinate.

3. Soil deep ploughing

The root system of balsam pear is well developed, and the main root can be up to 3 meters deep, so the soil preparation is to turn the soil more than 40 cm deep. Combined with Fatie, 5000 kg of fully mature barnyard manure, 50 kg of potassium sulfate compound fertilizer and 150,200kg of bean cake are applied per mu to meet the nutrient needs of balsam pear during the whole growth period. After deep ploughing and soil preparation, irrigation is carried out, and the shed is closed half a month before planting, and the ground is covered with old film. It was braised in a high-temperature greenhouse for ten and a half days to kill most of the diseases and insect pests in the soil so as to prevent the occurrence of some diseases and insect pests during the growing period.

4. Post-planting management

First of all, it is necessary to control the temperature and humidity after planting, and to increase the temperature of the greenhouse in the slow seedling stage to promote slow seedlings. In addition to the work of heat preservation and anti-freezing, proper ventilation is needed during the day. With the temperature rising, it is necessary to do a good job of ventilation and humidity reduction. Remove the skirt membrane around the bottom of the greenhouse when the daily average temperature is stable at 25 degrees, and keep the roof film against rain. Balsam pear likes fertilizer and moisture, so it grows well under the condition of sufficient fertilizer and water, and its yield is high and quality is good, so on the basis of applying sufficient base fertilizer, it is necessary to strengthen fertilizer and water management during the growth period. However, fertilization should be light in front and heavy in the back, in order to prevent burning seedlings, thin manure should be applied when seedlings are slow, and should be re-applied in the period of vigorous growth and flowering and fruiting, and foliar fertilizer of urea and potassium dihydrogen phosphate should be sprayed after each harvest. In addition, because balsam pear has strong branching and high cultivation density in greenhouse, it is easy to cause luxuriant branches and leaves, poor permeability, more nutrients consumption and less melon, so it is necessary to strengthen pruning and set up a frame to introduce vines.
