Catalpa, also known as catalpa, Juglans mandshurica, Juglans mandshurica, Shuitong, Juglans mandshurica, smelly sycamore, Juglans mandshurica, Juglans mandshurica, Liriodendron mandshurica, is a tree plant of the genus Catalpa of the family Liriodendron, up to 15m high. What does it look like? What's the moral? How much is the seed price per jin? What are the planting methods? It is learned from Jiangxi seedling base that the price of catalpa seeds is about 28 yuan / jin. The sowing rate per mu is 5m / mu and 6jin / mu.

What does the catalpa tree look like?

1. Catalpa, Liriodendron, Catalpa. Belong to deciduous trees, generally 6 meters high, up to 15 meters. The crown is umbrella-shaped, the trunk is straight and smooth, dark gray or grayish brown, and the shoots are sparsely pilose.

2. Panicle terminal, 10-18 cm long, peduncle, puberulent, 12-28 cm long; pedicel 3-8 mm long, sparsely hairy; calyx globose, 2 lips dehiscent, 6-8 mm long; calyx 2-lobed, lobes broadly ovate, tip acute. Corolla campanulate, yellowish, ca. 2 cm, 2-lipped, upper lip 2-lobed, ca. 5 mm long, lower lip 3-lobed, middle lobe ca. 9 mm long, lateral lobes ca. 6 mm, margin undulate, tube with 2 yellow bands and dark purple spots, about 2.5 cm long and 2 cm in diameter.

Capsule linear, pendulous, dark brown, 20-30 cm long, 5-7 mm thick, not falling in winter; leaves opposite or nearly opposite, sometimes whorled, leaves broadly ovate, similar in length and width, ca. 25 cm long, apex acuminate, base cordate, entire or shallowly undulate, often 3-lobed, leaf blade upper and lower rough, puberulent or nearly glabrous, lateral veins 4-6 pairs, basal palmate veins 5-7; petiole 6-18 cm long Seeds long oval, densely pilose at both ends, with hairs about 3 cm long and 3 mm wide, back slightly raised. Fertile stamens 2, filaments inserted on Corolla tube, anthers diverging; staminodes 3. Ovary superior, clavate. Style filiform, stigma 2-lobed. The flowering period is from June to July and the fruiting period is from August to October.

3, strong adaptability, like warmth, but also can withstand cold. The soil is better with deep, moist and fertile sandy soil. Not resistant to drought and barren. It has strong anti-pollution ability and fast growth. It can be cultivated in edge and corner land. Born in low mountains and valleys at an altitude of 500-2500 meters above sea level, moist soil, wild people have been invisible, mostly cultivated near the village and on both sides of the road.

What is the moral of catalpa tree?

At the end of the Han Dynasty, Chen Lin's words "Liang Xiaowang, the first emperor, mother Kun, tomb revered; pine and cypress Sangzi, you should be respectful" can also be confirmed in the article "Yuan Shaoyi Yuzhou". This is because in the eyes of the ancients, mulberry trees with strong branch regeneration ability and catalpa trees with fast growth and good quality are all trees of life, and people regard them as spiritual trees. Therefore, people who are drifting and living abroad for various reasons often feel homesick, respectful and homesick when they see these two kinds of trees. Over time, mulberry and catalpa have become symbols of their hometown, and "Sangzi" has become synonymous with their hometown.

What are the planting methods of catalpa trees?

Suitable environment for catalpa tree

The quality of the soil not only directly affects the growth of catalpa seedlings, but also directly affects whether the seedlings thrive or not. if the soil is very good, the growth environment is very good, so it will be much easier to take care of, and the quality of the seedlings. The speed of development will also improve a lot. Catalpa trees do not have strict requirements on soil quality, and it does not matter that they can be planted in sandy soil, loess, clay and soil with high sand content. However, the breeding seedlings should choose high-quality fields with fluffy and ventilated soil, rich in organic matter, flat terrain and smooth drainage. There was a lot of rain in summer, and Rain Water should be able to drain it immediately, otherwise some seedlings would die. The main purpose of the terrain is to facilitate the discharge of stagnant water, the soil is almost fine, the sunshine time is enough, and the catalpa tree has a good ability to resist cold, drought and waterlogging.

Land preparation

1. Cultivated land: catalpa seedlings are very sensitive to soil nutrients. If the soil nutrients are enough, the growth will be greenish and the plants will be healthy. But the soil quality of individual fields is basically the same nutrient topography, because of this, in order to grow thick seedlings, it is also necessary to apply a sufficient amount of base fertilizer before sowing, sprinkle with 3-6.5 thousand kilograms of cow dung and sheep manure per mu, plough once after fertilization, rake flat once, so that the soil quality and fertilizer are evenly mixed with water, and there is no large piece of soil, which is convenient for sowing and sprouting.

2. Making beds: in order to facilitate the necessary conservation measures such as watering, pulling grass and fertilizing the catalpa seedlings during the whole growing period, Changjing Garden suggests that the land should be made into a fixed 1.4-meter-wide border with a total length of 1625 meters, depending on the geomorphology.

Species

The seed grain size of catalpa tree is average, and the soil breaking rate is very good, so we can do some germination method properly before sowing. In fact, part of the process is very simple. Soak in clean water for one day, then take out the dry surface and plant it. The sowing depth is moderate or very shallow, and the soil cover depth is not more than 4 cm. Most of them use strip sowing, and after sowing, moisturizing film or moisturizing materials such as wheat straw can be laid to improve the budding rate. After sowing, artificial soil mulching or mechanical soil mulching can be used, and the soil can be irrigated once after covering the soil, and it can germinate in about 7-12 days.

Raise

The maintenance of catalpa in seedling stage is relatively few, it has few diseases and strong development. The most critical work is to irrigate and pull grass to control insect pests. During the peak development period of Astragalus membranaceus, a large amount of water and fertilizer is required. During this period, 40 kilograms of chemical fertilizer can be used per mu, and sufficient water is required when catalpa is growing most rapidly. At this time, we should make reference to the weather conditions and choose the opportunity to water.
