Israeli Stingless Cactus


The use of conservation facilities in the Central Plains and the North to cultivate cactuses is still a new life. The vegetable cactus has the characteristics of tolerance to drought and drought, requires lower cultivation techniques than planting fruits and vegetables, and has a shelf life of up to 2 weeks. Now its research and development of cooking technology has become more mature, salad, stir-fry, stew, roasted can be, not only nutritious and there is a certain amount of therapeutic effects, development prospects are considerable.

In 1997, we introduced Israel's Pachycereus pringlei from Israel. After several years of trial planting and propagation, the existing plants grown in greenhouses have a plant height of nearly 2 m and a stem diameter of 10 cm, and have entered flowering and fruiting stages. It shows that it can adapt to protected cultivation under saline saline soil conditions (pH>8.0). In north China and other northern regions, trial planting and promotion can also be conducted.

First, form and nutrients

The palm piece was circular when introduced, but the shape of the palm piece was a long ellipse due to the light conditions after introduction. According to another test, under long-term drought conditions, 2 to 3 5-mm-thick stings and 1 1-piece cluster of hairy hair appear on the seat. The contents of amino acids and other nutrients are shown in Table 1.

Compared with Mibangta's cactus, Yu Dongping's data: the content of water-soluble amino acid and tyrosine is 0.465% (dry mass), which is much higher. Compared with the data of Wu Kexian and others, each 100g is fresh. The masses of aspartic acid, serine, and glycine were 38.40 mg, 14.82 mg, and 12.24 mg, respectively, while those of valine, isoleucine, leucine, and histidine were 18.44 mg and 18.44 mg, respectively. 18 mg, 16.76 mg and 14.96 mg, and how much the other 10 amino acids are mutually different (the difference being ≤100 mg/kg fresh mass).

II. Precautions for cultivation in northern protected areas

1. The cutting and cutting propagation is the most convenient and practical. After selecting the robust palm piece, it needs a little drying to make the wound heal. The substrate used is clean sandy loam soil and suitable humidity is required (water holding capacity is about 20%). The cutting depth should not be less than 1/3 of the palm. Never use unfermented organic fertilizers and cuttings that have not yet dried on the excised wounds for cutting.

2. In greenhouses or plastic film solar greenhouse cultivation, in order to take advantage of the open conditions in the summer, it is advisable to plant the plants two weeks after the end of the night cream, and then cover them with protection after the fall. The way of planting shall be such that the back (side) surface of the palm piece is north-south, so that the palm piece is evenly received on both sides of the palm, and it is beneficial for inserting the support in the future. In addition, it is best to adopt a wide and narrow row dense planting, wide row spacing 50cm, narrow row spacing 30cm, spacing 40cm, about 667m2 per plant can be planted 4100.

3. Prior to planting, appropriate amount of basal fertilizer should be added. Because it has been cultivated for many years, it is necessary to appropriately control the ammonia fertilizer and increase the application of phosphorus and potassium fertilizers. In addition, decomposed organic fertilizers are added every year or every other year between rows.

4. Vegetables should not be over watered with cactus, especially in the rainy season should pay attention to flood control. Low-lying land can be cultivated on high ridges.

5. The maximum temperature in the daytime in the facility is controlled at 30°C, which should not exceed 35°C; the minimum temperature at night should not be lower than 10°C, and strives to maintain 15°C. Under the premise of properly grasping the temperature, it is necessary to strengthen ventilation as much as possible, especially after watering, in order to reduce the humidity.

6. The newly planted cactus must be harvested after it has grown to the third layer of palm. The harvesting standard was timely harvested when the 3rd to 4th rows of scales at the base of the young palm were removed. The harvesting method should be cut with a knife instead of hand. In order to improve the quality and flavor of the palm piece, it is necessary to harvest it after 15 o'clock so that the acidity of the palm piece will be much lower than that obtained in the morning or in the morning.
