What does a pineapple whole plant look like?

Pineapple plant adaptability is strong, barren and drought tolerant, less pests and diseases, is an important pioneer crop in the new reclamation mountains, easy to cultivate, high yield, can also be intercropped, is a good tree species for the development of southern hilly and mountainous areas, the development of rural economy and the prosperity of farmers. 3800 4000 pineapple plants are planted per mu, and the number of seedlings is large, and three methods are commonly used: plastic resin germination propagation, vegetative body propagation and tissue culture. Germination time and method:

5 In November, plants with 40 cm long green leaves, usually 40 leaves of caine species, 35 leaves of Philippine varieties. Each plant was filled with 250 mg of ethephon plus 1 urea and potassium chloride mixture 25 ml of germination, and then 1200 times and 600 times and 25 ml of 750 times plasticin solution were used on the 5th and 12th days after treatment, respectively. Vegetative body propagation, commonly used seedling cultivation, that is, the use of small parietal buds in the field pineapple, small support buds, small sucking buds and fruit nodules buds are classified and planted in nurseries and then go abroad.

Seedlings were cultivated by using small buds left on the fruit stalk after fruit picking, and old stems were used to cut into pieces to propagate and renew old stems. Tissue culture seedlings were cultured in MS medium at room temperature for 30 hours, 12 hours of light or natural light culture room. Technical points of pineapple quality and abundant yield:

The first is to choose a good garden land, choose a place facing south in the north, with abundant sunshine, abundant water sources and convenient transportation as a commodity production base. The second is scientific planting, before planting, improve the barren soil and apply sufficient base fertilizer; Select strong seedlings for planting. Density, 3000 4000 plants per mu of caine and 4000 5000 plants of queen species.

The third is to strengthen fertilizer and water management after planting, and the amount of fertilizer is applied to each mu in Guangxi, with kilograms of nitrogen, phosphorus, potassium, and N P2O5 K2O 1; During the fertilization period, usually from December to February of the following year, before budding, bud promotion fertilizer is applied, and strong bud fertilizer is applied in July and August after fruit picking; Apply strong fruit germination fertilizer between bud promotion fertilizer and bud strengthening fertilizer; Apply foliar fertilizer once a month and top dressing twice a month, with 1 urea plus potassium sulfate solution; Apply basal fertilizer after fruit picking. Water management should be carried out in a timely manner to prevent waterlogging and drought control. Fourth, do a good job in other management, such as in order not to affect the growth and development of fruits, should be appropriate to remove buds and leave buds; In order to promote flowering, it is necessary to promote flowering; In order to improve the weight and quality of the fruit, spray the fruit, spray the fruit with 50 milliliters of gibberellin and urea solution after all the florets have flowered, and spray 70 milliliters of gibberellin plus urea solution for the second time after 20 days.

In order to make the fruit ripen consistently, when the fruit has developed to seven ripeness, spray the fruit with ethephon 300 mg liters to ripen the fruit. The more serious infectious diseases of pineapple mainly include heart rot, black rot and small fruit brown rot; Non-infectious diseases include sunburn and nutrient deficiency. Pests include pineapple mealybugs, Chinese crickets and grubs.

The method of growing pineapples is actually very simple!

lz, isn't cultivation just planting......

Pineapple is native to Liangguang and Yunnan in China and is a tropical crop. The plant is 70-80 cm tall, the leaves are narrow and long, with serrated edges, and the weight of a single fruit is generally kilograms. In 1997, the northern greenhouse was successfully introduced, with a yield of more than 5,000 kilograms per mu, and the shape, color and taste of the fruit were better than those of origin, and it was resistant to disease and insects, and had strong fecundity.

1. Planting method Before land preparation, apply 5,000 kg of fermented and rotted farmhouse fertilizer and 25 kg of soybean cake per mu. Ploughing depth 25-30 cm, leveling, adjusting the north and south furrows. Two meters for a planting belt, 50 cm back, 150 cm furrow surface, the height difference of the back furrow can be watered, not too large.

Each furrow is planted in 4 rows, the plant spacing is about 30 cm, and the density per mu is 4000 4500 trees. Ditching and watering or plowing holes can be used for planting.

Second, the management method of the seedling stage to appropriate watering, pay attention to soil breaking, weeding, and promote the growth of stems and leaves (Jin Leaves and Jin Fruit). The requirements for fertilizer during the growth period are not strict, and according to the situation, according to the situation, according to the nitrogen, phosphorus and potassium 2:1:

3 administration. Cover a greenhouse before the frost falls. In the severe winter season at night and in windy and snowy days, the shed should be covered with straw, and when it is very cold, the temperature must be raised with heating facilities, and the shed should be kept above 5 to prevent the plants from being frozen.

In the beginning of summer, the shed must be drained in the rainy season to prevent rotten fruits. Before flowering and fruiting, a wire should be pulled in the middle of every two rows to fix the fruit stalk and prevent the fruit from lodging. The tender concave heart at the upper end of the pineapple fruit is easy to hide insects, and it can be prevented by breaking off the tender heart or covering it with grass.

Pesticides are basically not used throughout the growing season. Cultivated in the north, the fruit ripens for 11 months from planting, and the ripe pineapple has a flat, yellow peel and exudes a fragrance.

3. Reproduction After picking fruits, leave a side bud closest to the ground to cultivate, for the next year's fruit, the remaining 6 7 side buds and top buds can be broken down and cultivated, the first year of planting 1 acre, the second year can develop 7 acres.

Pineapple, also known as pineapple, belongs to the bromeliad family, bromeliads, and is a perennial monocotyledonous herb. Pineapple is a tropical fruit, native to Central and South America, introduced to China in the 17th century, and has been planted in the 18th century. As a fresh food, pineapple has a golden flesh color, rich fragrance, sweet and sour taste, crisp and juicy.

Processed products canned pineapple is known as "international canned fruit", and can also be made into a variety of processed products, which are widely welcomed by consumers.

Pineapple leaves are the leaves of the pineapple plant and belong to the perennial herbaceous plants. Originally discovered in South America, pineapples subsequently spread to the United Kingdom and the United States, where they became a fairly popular fruit. The leaves of the pineapple plant are arrow-shaped, withered, dark green, and have many needle-like spikes.

The ** part of the pineapple leaf is fibrous due to the fact that the plant needs to collect water in order to grow, and these fibers help the plant store water.

In addition to being a fruit, the leaves and roots of the pineapple plant have many medicinal properties. In many places, people use pineapple leaves for pain, anti-inflammatory, and digestive problems. Pineapple leaves are rich in enzymes and nutrients, including vitamin C and manganese, which can help improve the body's immune system and cellular health.

In addition to its medicinal properties, pineapple leaves are widely used in the textile industry. Because they can be processed into very thin fibers, the latter can be spun into yarn and woven into satin and other textiles. These textiles are not only soft and comfortable, but they are also very tough and durable.

In conclusion, pineapple leaves are a very important component of the pineapple plant, which can not only be eaten as a delicious fruit, but also have great medicinal value and a wide range of industrial applications. <>
