Planting technique of ground pineapple

It is estimated that many people are very confused. They have only heard of pineapple. What is there in pineapple? In fact, the ground pineapple is the pineapple on the long ground, because there are two kinds of pineapple, one growing on the tree and the other growing on the ground, so the ground pineapple is the pineapple we often eat. So how to grow pineapples?

Planting technique of ground pineapple

1. Planting method

Before soil preparation, 5000 kg of fermented farm manure and 25 kg of bean cake were applied per mu. The depth of ploughing is 25ml / 30cm, leveling and adjusting the border between the north and the south. Two meters for a planting belt, 50 cm back, 150 cm border surface, back border height difference to be able to water, does not require too large. 4 rows were planted in each border, the distance between plants was about 30 cm, and the density was 4000Mu / mu. Ditching and watering or planing and watering can be done.

2. Management methods

The seedling stage should be watered properly, pay attention to breaking the soil, weeding, and promoting the growth of stems and leaves (Jack leaves and fruits). Growth period of fertilizer requirements are not strict, according to the situation, according to nitrogen, phosphorus and potassium at 2:1:3 application. A greenhouse will be built in front of Frosts Descent. In the severe winter night and snowy days, grass mulch should be used to cover the sheet. when it is very cold, the temperature must be increased by using a heating device to keep the greenhouse above 5 ℃ to prevent the plant from freezing. The Beginning of Summer removed the shed and must be drained in the rainy season to prevent rotten fruit. Before blooming and fruiting, pull an iron wire between every two rows to fix the fruit stalk to prevent fruit lodging. The tender concave heart at the top of the pineapple is easy to hide insects, which can be prevented by breaking off the tender heart or covering it with grass. Pesticides are basically free of pesticides throughout the growing period. Cultivated in the north, from planting to fruit ripening for 11 months, the mature pineapple peel is flat, yellow and gives off fragrance.

3. Reproduction

After fruit picking, a lateral bud closest to the ground is left for cultivation in preparation for fruit in the coming year. The remaining 6-7 lateral buds and terminal buds can be broken off and cultivated, planting 1 mu in the first year and 7 mu in the second year.

Technology of Pineapple in potted planting Field

1. Choose healthy pineapples, because pineapples have been stored for some time, and some of the leaves are withered, so if you plan to plant pineapples, you must buy pineapples with fresh leaves, such as the white powder of the leaves are still there, the leaves are green, and so on. In order to improve the success rate, you can buy one more, two or three potted plants together.

2. After selecting the pineapple, cut off the top bud with a knife, tear off the lower layer of bracts, leave it cool for 3 days, wait for the incision to be dry, and then hang water for a few days mainly to wait for the plant to collect water and not rot so easily.

3. Take a transparent bottle and fill it with about half of the water, and insert the top bud into the induced root. You can see the root tip in about 7 days, and then plant it in a flowerpot. Potted pineapples have no special requirements for soil, and do not need to be watered too hard until they are dry. It doesn't matter whether you use the rooting agent or not, because pineapple is easy to grow, and a pot of 30 centimeters in diameter is enough.

4. After potted pineapple is planted, it should be sunny enough. If you manage it well for more than half a year, you can start a bud, from flower to fruit for about 200 days. In winter, the outdoor temperature should be about 5 ℃ to enter the room for the winter, keep the light and often moist leaves, and wait for the spring to move outside.

Where is the suitable place to grow pineapple?

Pineapple is a tropical perennial herbaceous fruit tree, which likes to be warm and humid, avoid low temperature frost, strong drought resistance, but good growth and development requires sufficient moisture, insufficient or excessive or uneven rainfall, which should be regulated by drainage and irrigation. Pineapple is native to tropical rain forests and tropical plateaus, with strong shade tolerance, like diffuse light, avoid direct light, but high yield and high quality still need sufficient light. Pineapple is widely suitable for soil, but it is not suitable for neutral or alkaline soil, clayey or unstructured silt. PH5~6 is required. The pineapple plant is short and less harmed by the wind, but the strong wind above 6 °can also cause damage.

Temperature is the most important ecological factor affecting the growth, development, yield and quality of pineapple. According to the study, pineapple can grow at 15-40 ℃, 28-32 ℃ is the most suitable, 10 ℃ grows slowly or stops, chilling injury occurs if it lasts less than 5 °℃, 1-2 ℃ can survive for 1-2 days, and if it is too long, it will be seriously damaged. Compared with other tropical herbaceous fruit trees (such as banana and papaya), pineapple has stronger tolerance to low temperature and short frost. The response of different pineapple varieties to temperature was different. The average temperature of the day was about 13 ℃, but it did not blossom until 16 ℃. Drought and extreme heat can also inhibit the blooming of flowers or lead to incomplete flowering. The length of fruit ripening period and quality are also closely related to temperature. From budding to maturity, the average temperature increased by 1 ℃, and the days of maturity decreased by about 5-8 days. If the temperature is high, the sunshine is strong, and the moisture is sufficient, the ripening period is short and the quality is good. Therefore, in general, the ripening period of summer and autumn fruit is shorter than that of winter and spring fruit, and the flavor is good.

Pineapple is a drought-tolerant crop. According to the study, the daily evapotranspiration of pineapple is about 4.5 mm. Even if the original water content of the soil is relatively high, as long as there is no precipitation for 3-4 weeks, the soil water can be exhausted. Therefore, attention should be paid to the proper supply of water in the growth and development of pineapple. In order to ensure its normal growth and development. However, pineapple is a shallow-rooted aerobic crop with too much water and too much soil moisture, which will cause poor soil ventilation, hinder nutrient absorption and utilization, and seriously cause root rot and death.

Pest control

1. Fusarium wilt of Sri Lanka pineapple: after the disease of the plant, the leaves became soft and drooping, the leaves were light green to red, the base rotted, and finally the whole plant withered. The disease is caused by pink beetle insects.

Prevention and control methods: first of all, we should pay strict attention to the propagation of diseased seedlings. Secondly, the beetle should be extinguished in time. Soak the head with 500 times dimethoate solution when planting, then plant it upside down and dry. If it is found that the beetle is harmful after planting, it is necessary to spray dimethoate 500x liquid in time, or 25% Zhong Ke Meiling 1500 times liquid. In addition, if diseased plants are found in pineapple orchards, they should be dug up in time to prevent them from spreading.

2. Black rot: the core of the damaged fruit blackened and gradually expanded to the whole fruit rot, and most of the germs invaded from the bud picking place and the fruit stalk wound.

Prevention and control methods: be careful not to top and pick fruit in rainy days, so as to reduce the chance of germs invading. This disease is also the main disease of storing pineapple fresh fruit.

3. Seedling heart rot: seedling heart rot and death. It is mainly caused by stacking heat or stagnant water.

Prevention and treatment: avoid stacking seedlings for too long, especially in the process of long-distance transportation, so as to avoid fever and injury caused by high temperature, high humidity or airtight. Spread out immediately after arriving at the destination and plant after a little sun for 1 ~ 2 days. Avoid planting in rainy days and pay attention to deep ploughing and shallow planting.

As mentioned above, the cultivation of pineapple is very simple, that is, it can be planted at home. Usually we throw away the pineapple leaves after eating the pineapple, and the discarded pineapple leaves are pineapple seedlings. Plant it in a pot and take good care of it. It will slowly take root and grow new leaves and even produce pineapples.
