35 芭乐 2. 健康益处

36 Medicinal properties of Guava fruit

37 1. Cancer prevention( 防癌 ) 2. Lower Blood pressure( 降血压 ) 3. Reduce Blood sugar( 降血糖 )

38 1. ( 防癌 ) Cancer prevention

40 纤维 Xiānwéi 钾叶酸番茄红素

41 叶酸 Some studies have found that folic acid taken by women before they become pregnant and during early pregnancy may reduce the chances of certain birth defects (neural tube defects).

42 番茄红素 Lycopene may cause low blood pressure. Caution is advised in people who have low blood pressure or those taking drugs or herbs and supplements that lower blood pressure. Cancer prevention (general) Although it has not been well studied in humans, early research suggests that lycopene may help prevent a number of different cancers, including bladder cancer and skin cancer. However, the reason behind this potential benefit remains unclear.

43 Intravenous (IV) vitamin C was studied in patients with breast cancer who were treated with adjuvant chemotherapy and radiation therapy. The study found that patients who received vitamin C had better quality of life and fewer side effects than those who did not. The U.S. Food and Drug Administration (FDA) has not approved the use of highdose vitamin C as a treatment for cancer or any other medical condition.

47 但是, 我们没有直接证据吃番石榴可以预防癌症 But we do not have direct evidence that eating guava could prevent cancer

48 2. 降血压 Lower Blood pressure

49 J Hum Hypertens Feb;7(1):33-8. Direct evidence: Can guava fruit intake decrease blood pressure and blood lipids? Singh RB1, Rastogi SS, Singh NK, Ghosh S, Gupta S, Niaz MA. Author information Abstract A randomized, single-blind, controlled trial was conducted to examine the effects of guava fruit intake on BPs and blood lipids in patients with essential hypertension. Of 145 hypertensives that entered the trial, 72 patients were assigned to take a soluble fibre and a potassium-rich diet containing kg of guava daily (group A) and 73 patients to their usual diet (group B), while salt, fat, cholesterol, caffeine and alcohol intake were similar in both groups. Mean age, mean body weight and male sex, were similar, and so were risk factors, mean BPs, mean serum sodium, potassium, calcium, magnesium, triglycerides, cholesterol and HDL-cholesterol in both groups. Dietary adherence to guava intake was checked by a questionnaire. After four weeks of follow-up on an increased consumption of dietary potassium and low sodium/potassium ratio, group A patients were associated with 7.5/8.5 mmhg net decrease in mean systolic and diastolic pressures compared with group B. Increased intake of soluble dietary fibre (47.8 +/ vs / g/day) was associated with a significant decrease in serum total cholesterol (7.9%), triglycerides (7.0%) and an insignificant increase in HDL-cholesterol (4.6%) with a mild increase in the ratio of total cholesterol/hdl-cholesterol in group A patients compared with group B. It is possible that an increased consumption of guava fruit can cause a substantial reduction in BPs and blood lipids with a lack of decrease in HDL-cholesterol due to its higher potassium and soluble fibre content, respectively.

50 1. Cancer prevention( 防癌 ) 2. Lower Blood pressure( 降高血压 ) 3. Reduce Blood sugar( 降血糖 )?

51 Note this is Tea and not Guava fruit

52 True for Guava Tea But not guava fruit!!

55 3. 气候和光周期 Climate and photoperiod

56 芭乐树销售地带 Guava Tree for Sale

57 Minimum temperature

58 芭乐树 1. 热带到亚热带 (Tropical to sub-tropical) 2. 可达 20 英尺的高度 3. 冷天和冰冻时需要保护

59 3. 气候和光周期

60 光合作用 Photosynthesis

61 Stomata located underneath the leaf

62 水肥可以从气孔进入叶子吸收 Water and fertilizer could enter the leaf via the Stomata Water Fertilizer

66 Various points of entry of Iron and phosphorus as foliar spray

67 Minimum 6 to 8 hrs of sunlight

69 Knowledge of time of stomatal opening allows one to determine what day of sunlight is optimum for plant growth

70 6 am to 3 p.m 叶子 0, 3, 6, 9, 12, 3, 6, 9, 12

71 Stomata opening and photosynthesis share same rhythms :-Time of opening of stomata is the same as time of food synthesis Best time is 6 am to 3 p.m

72 需要至少 6-8 个小时的光照时间最好的光照时间是 6am-3pm 位置向东南避免西北冷风

73 4. 土壤 The guava will tolerate many soil conditions, but will produce better in rich soils high in organic matter. They also prefer a well-drained soil in the ph range of 5 to 7. The tree will take temporary waterlogging but will not tolerate salty soils.

83 Different grades of gardening sol earthworm

84 地膜, 以保持水 Mulch to keep moisture

86 5. 种植 (Planting)

87 昨天看了种树积水的讨论, 赶紧把新种的三角梅挖出来重种果然是水坑呀

89 新移栽的果树要在土壤线以上 New plant should be placed above the soil line in Houston

90 Plant receive water, oxygen and nutrient via small root hairs

93 Break up the root system Almost no soil

94 Break up the root system

95 Good root system 1. Buy small plant 2. Break up root 3. Do not buy root bound plant

96 用 Mulch 保持湿度 Where to buy rice straw?
