What plants can be planted in soil and water?

Plants that can be planted in soil and water include Phyllostachys pubescens, Lysimachia christinae and hyacinthus orientalis.

First, abundant bamboo.

1, soil culture

Because Phyllostachys pubescens is an ornamental plant that likes humidity, it is suitable for cultivation in paddy fields with loose and fertile soil.

2. Hydroponics

Before planting, the leaves at the base of the cuttings should be cut off, and the base should be cut into oblique mouths with a sharp knife, and the incision should be smooth so as to absorb water and nutrients. Change clean water every 3 to 4 days 1 time, keep the direction unchanged for 10 days, and grow silvery white fibrous roots in about 15 days.

Water should not be changed after rooting, and water can be added in time after water evaporation is reduced. Changing water frequently can easily lead to yellowing of leaves. After rooting, a small amount of compound fertilizer should be applied in time to make the leaves oily green and the branches stout. If fertilization is not applied for a long time, the plants will grow very thin and the leaves will turn yellow easily. However, fertilization should not be too much, so as not to cause "root burning" or ineffective growth.

Second, Lysimachia christinae

1, soil culture

It is advisable to choose fertile sandy loam and cool and humid plots for planting, or use corners of houses and shady wetlands beside ponds and dams for sporadic cultivation.

2. Hydroponics

Lysimachia christinae has strong adaptability to the pH of water, but it is best to control it between 6.5 and 7.5. Like humidity, it is more common in places with running water. Born at an altitude of1300-1980m, on slopes, grasslands, roadsides or ditches. It likes warmth, avoids high temperature and endures low temperature. It grows well in the temperature range of 16 ~ 24℃, and the overwintering temperature is not lower than 5℃. When the room temperature exceeds 30℃, the growth of plants will be inhibited.

Third, soil culture and hydroponics in hyacinthus orientalis.

1, soil culture

Hyacinthus orientalis should choose sandy loam with good drainage and not too dry, which requires fertile soil, high organic matter content, good aggregate structure, neutral to slightly alkaline and pH value of 6-7; The ratio of humus soil 5∶ garden soil 3∶ coarse sand 1.5∶ bone meal 0.5 can be used to prepare culture soil.

Before planting, after the soil temperature reaches 10- 15℃, the soil surface can be covered with a thin film with formalin and other chemicals immediately. After three days of warm weather, the film can be uncovered and planted in the air for 1 day to keep the soil moist. Apply sufficient base fertilizer before planting and cultivate in the field to avoid continuous cropping.

2. Hydroponics

Water conservation in hyacinthus orientalis requires that the water level should be 1-2cm away from the bulb bottom, so that the roots can breathe. It is forbidden to inject water without passing through the bottom of the bulb. Seed balls can be placed in wide-mouth glass bottles in June+February, 5438, and adding a little charcoal is helpful for anti-corrosion and disinfection.

Its seed balls can only be soaked to the bottom of the ball, but they are placed in the dark and covered with black cloth, so that they germinate in a completely black environment for about 20 days, and then they are exposed to the sun outdoors. At first, they glow 1-2 hours a day, and then gradually increase to 7-8 hours. Most of them can bloom in the Spring Festival when the weather is fine.

Extended data:

The core of hydroponics is to directly soak the roots of plants in nutrient solution, which can replace soil and provide growth factors such as water, nutrients and oxygen for plants to grow normally.

In order to make plants get balanced nutrition, various substances in the soil must reach the best proportion. Unfortunately, this "perfect" soil is rare in nature.

After hydroponics, plants can directly absorb nutrients and water in nutrient solution through roots, and people can manually mix nutritionally balanced solutions to achieve a balanced "diet" of plants, which is obviously much easier than finding perfect soil. Because these solutions are packed in containers, they can be recycled, will not flow into the soil, affect the environment, and are safe, reliable and sustainable.
