There is a long history of pineapple cultivation in Chaoan County, Shantou City. Currently, the main varieties are Balinese (Dazhihongmaoli) and Cain (Saladue), which are mainly distributed in Dengtang Town and Guxiang Town. In the past 10 years, under the guidance of agricultural technicians, farmers in Chaoan County have carried out anti-season high-yielding cultivation of pineapple, and succeeded in planting, promptly urging and promoting fruit, and bagging and protecting fruits against cold. Through continuous experiments and practices, personnel and farmers have concluded a set of pineapple anti-season high-yield cultivation techniques, which have been popularized and applied, and have achieved good economic benefits.
First, according to local conditions, choose the land to build the park in accordance with the external environment of pineapple requirements, choose the lighter winter frost damage, no frost or less frost, soil pH value of 4.5-6.0 slopes for the garden. After the garden is selected, build horizontal terraces along the contour line, deepen 40-50 cm deep, thoroughly excavate the roots of thatch and weeds, and dig wells for flood protection and drainage according to the size of the lot.
Second, timely planting, reasonable close planting pineapple planting time is not very strict, in addition to the cold from December to next January drought should not be planted, the rest of the time can be planted. The pineapple cultivated in the off-season should be marketed in the March-April of the following year in the off-season fruit season. Therefore, it must be planted in March, and the thick-stemmed, dense-leaved and robust old mature buds or large buds should be planted. When planting, it is required that the bud has more than 10 large leaves and more than 200 grams of fresh weight. According to the production practice, the local planting density is preferably 1000-1200 strains per mu.
Third, the reuse of potash fertilizer, application of basal pineapple fast-growing high-yield, need a large amount of potassium, so the application of base fertilizer, reuse of potassium is an important measure to seize the high yield of pineapple. Basal fertilizer is dominated by grass ash and soil miscellaneous fertilizers, with a small amount of superphosphate, 0.25-0.5 kg per hole. Practice has shown that the application of base fertilizer can help improve the structure of soil aggregates, enhance soil permeability and water retention and fertility, and create a favorable soil environment conducive to the growth of pineapple roots; at the same time, nutrients can be absorbed and accelerated after the seedlings survive. The growth of the leaves promotes robust growth and early yield. In addition, the application of base ash such as grass ash can improve the cold resistance of plants.
Fourth, timely fertilizer, strengthen management
1. When the top-dressing seedlings are alive at a proper time, top dressing is applied once every 1-2 months during vegetative growth, and 25 g of urea per plant is applied. The topdressing should be carried out after rain. In July, we reapplied one flower fertilizer and applied 50-100 grams of compound fertilizer per plant. In addition, dressings were applied 1-2 times (0.2%-0.4% aqueous urea solution) outside the roots during fruit enlargement. The weather warms up after February every year. We must strengthen fertilization management and timely perform extra-root fertilizers to promote rapid plant growth.
2, between the rows covered shallow pineapple root group, in order to protect the root groups, to keep the soil moist, inhibit the growth of weeds, reduce the summer and autumn temperatures to improve the soil temperature in winter, which will help the root group grow robustly, we must seriously do a good job among small businesses Year covered. Cover can use straw or mountain grass, covering a thickness of 3-4 cm.
3, the cultivator weeding pineapple root system is a good qi, we must maintain the soil loose air. Between small rows and under the crown of leaves, the root groups are densely superficial, and if grass covered without straw, weeds should be promptly plucked. When weeding weeds, we should pay attention to shallow weeds so as not to damage the roots. The cultivating and weeding operations are usually performed 1-2 times before and after weeping and wetting of the weeds in May. After October, when the weather becomes drier, it should also be cultivating loose soil, drought protection and moisture, in addition to net weeds.
V. promptly urge flowers and adjust fruit collection period
1. The pineapple planted in March is planted after 5-6 months of fast-growing cultivation. In August, when the plant grows to 35 cm or more and has 25-28 blades 35 cm or more, the fruit can be obtained in the following year. In March and April, the market is relatively concentrated and the harvest period must be elicited with ethephon, with a concentration of 0.025%-0.05% (with 40% ethephon 100 ml plus fresh water 80-160 liters). When the temperature is high, the concentration is lower, The concentration is higher when the temperature is low. Adding 1% urea to the ethephon dilution results in better results. Each strain is poured into (perfused) 20-50 ml of the prepared diluent, or the sprayer cap is removed with a backpack sprayer and the liquid is sprayed from the heart of the plant. Ethephon flowering should be done before 10:00 am or after 5:00 pm on a sunny day, and usually after 28-30 days. The following problems should be noted when ethephon is used: (1) Plants that promote flowers must have robust plants based on a certain vegetative growth. That is, there must be 25-28 leaves of 35 cm or more in length if the plants are too small. Or too weak, although the results will be fruit after treatment, but if the small yield is low, the value of the goods is lost. (2) Ethephon is a plant growth regulator rather than a fertilizer, so it is necessary to increase fertilization before and after flowering to achieve the purpose of increasing production. (3) Grasp the appropriate concentration of the drug solution, the concentration is too high, it will not only waste the drug, but also inhibit growth.
2. Promote large-fruit expansion with 0.2%-0.4% urea aqueous solution for extra-root dressing, promote fruit development, in order to achieve high yield and quality purposes.
6. After topping the buds and shoots, they should be topped in time, remove crown buds and excessive suckers, concentrate the nutrient supply of small fruit growth, and also keep 1-3 strong buds near the ground as the replacement mother after fruit picking. Strains.
Seven, bagging pineapple care warmth, fear of frost, should be in front of "Xiaohan" bagging protection against cold. The pineapple fruit bag is generally used vest bag, easy to tie. When bagging, care should be taken not to break the bag and add a layer of paper or cloth in the bag to facilitate absorption of moisture and moisture while preventing ice formation. Practice has proved that after the bagging treatment, the fruit size is large without cracking the fruit and the economic value is high. The fruit without the bagging protection is small and cracked, and the economic value is low, losing the significance of anti-season cultivation.
Eight, pest control pineapple off-season cultivation, due to lower temperature when the fruit matures, less pests and diseases. Therefore, in addition to the prevention and treatment of rat larvae during fruiting and fruit ripening period, the rest of the time can be controlled without chemicals, so that the product meets the pollution-free requirements.
Nine, timely harvest pineapple off-season planting, planting after a year of cultivation and management, to the next year in March and April can enter the harvest period, when the fruit at the base of 2-3 rows of small fruit is yellow, slightly wrinkled fruit handle The fruit can be harvested when it is slightly tilted on the stem. Pineapple fruit harvesting should be carried out in batches in stages, first harvesting first.
After harvesting fruit, it will enter the management of the second growth cycle. The productive period of pineapple is generally 2-4 years, and the output is sharply reduced after the 5th year.
First, according to local conditions, choose the land to build the park in accordance with the external environment of pineapple requirements, choose the lighter winter frost damage, no frost or less frost, soil pH value of 4.5-6.0 slopes for the garden. After the garden is selected, build horizontal terraces along the contour line, deepen 40-50 cm deep, thoroughly excavate the roots of thatch and weeds, and dig wells for flood protection and drainage according to the size of the lot.
