The latest summer squash winter seedling technology tutorial

Zucchini is suitable for spring sowing or autumn sowing, when the climate is suitable for its growth and development, and in order to meet the market demand, many plants often use greenhouse technology to plant in winter, zucchini planting in winter should first do a good job in seedling technology. So how to raise zucchini seedlings in winter? Let's get to know it with the editor.

1. Soil preparation and fertilization

The varieties with strong disease resistance, high yield and good appearance should be selected before planting, which is the basis of high yield. Zucchini first slightly acidic soil, the suitable soil pH value between 5.56.8, so in the selection of this point should be taken into account. In addition, zucchini like fertility is strong, if the application of too much nitrogen fertilizer, then it is very easy to lead to excessive growth of stems and leaves, resulting in serious flower and fruit drop and high incidence of diseases and insect pests, so try to be reasonable nitrogen, phosphorus and potassium fertilizer. In general, if you don't produce 1000 kilograms of zucchini, you need to consume 3.92kg of pure nitrogen, 2.13kg of phosphorus and 7.29kg of potassium.

2. Sowing and raising seedlings

No matter using seedling bed or nutrition bowl to raise seedlings, the preparation of nutritious soil should be done before sowing, which is the key to cultivate strong seedlings of zucchini. Generally take one-third of the fertile garden soil that has not been planted with melons and fruits in 3-4 years, a rotten ring fertilizer, add a small amount of plant ash, sift it, put it into a nutrition bowl or make a bed, and then prepare to sow, and cover two centimeters of soil after sowing. In addition, in order to control underground pests, you can sprinkle a small amount of wheat bran with methamidophos on the border, and then use a small arch shed to keep warm and moisturize until seedling emergence.

3. Strong seedling standard

After emergence, it is necessary to strengthen management and cultivate strong seedlings, in which the standard of strong seedlings is about 30 days old, with 3-4 true leaves and a plant height of about 10 cm. The stem diameter is about 0.5 cm, the petiole length is equal to the leaf length, the leaf color is dark green, the cotyledons are intact, and the root system is well developed. such strong seedlings have strong growth, high survival rate after planting, and higher yield.

4. Temperature management

The temperature is relatively low in winter, and temperature control is the key to the normal growth of zucchini. Through greenhouse technology, the temperature should be kept between 20 and 25 degrees during the day, and more than 25 degrees should be ventilated and cooled down. It should be kept between 10-15 degrees at night, and the lowest should not be less than 6 degrees. At the same time, watering should be controlled during this period. Small water can be irrigated appropriately when there is a shortage of water, but attention should be paid to ventilation after watering to reduce air humidity and prevent diseases.
