I. Materials and methods
1. test base
Group 3, Village 8, Tuomuwusitang Township, the soil type is irrigated and silted soil with medium fertility, and the previous cotton is interplanted with almonds. The experimental site is irrigated in winter.
2. Varieties to be tested
Hongta Pepper, Yiduhong, Hongfeng Dried Pepper, Jinhong Dried Pepper, American Sweet Pepper, Pigment Sweet Pepper and Line Pepper are 7 varieties.
3. Experimental design
In this experiment, random block arrangement was used for seedling transplantation. The plot length is 7.5m, the width is 1.2m, the row spacing is (60+60)cm, the plant spacing is 25cm, and the plot area is 9m2. Each plot has two rows of membranes, repeated three times, totaling 2 1 plot, and the net plot area is 189m2.
Second, the test record content
1. Seedling situation
The experiment was carried out on February 27th, sowing and seedling raising, and transplanting on April 8th.
2. Test records
The experimental records include germination stage, flowering stage, fruit setting stage, fruit expansion stage and maturity stage. According to the actual yield, the single fruit weight, yield, plant height and incidence of umbilical rot in each plot were determined.
3. Tian Tuan management
Third, the results and analysis
Comparison of growth period of 1.7 pigment pepper varieties
American sweet pepper and pigment sweet pepper are 2-4 days earlier than other varieties; From the comparison of growth process: from the budding stage, flowering stage and maturity stage, line pepper is 5- 10d, 5- 12d and 2-5d earlier than other varieties.
2. Comparison of yield among treatments of 7 varieties of pigment pepper.
The yield difference is obvious. The highest yield is Hongfeng dried pepper, which grows steadily, followed by American sweet pepper, and the lowest yield is Jinhong dried pepper and linear pepper.
3. Comparison of Biological Characteristics of Seven Pigmented Pepper Varieties
3. 1 plant height: the plant height varies greatly among different varieties. Hongta pepper and American sweet pepper are higher than other varieties15-25 cm; The plant height of line pepper is the lowest, about 40cm lower than that of Hongta pepper and American sweet pepper on average.
3.2 Single fruit weight: This character is determined by variety characteristics. American sweet pepper and pigment sweet pepper have larger fruit types, which are 5-6g higher than other varieties on average.
3.3 Umbilical rot: There are significant differences among varieties, but no significant differences among repetitions. The resistance of Jinhong dried pepper to navel rot is better, and the incidence rate is lower than other varieties 14%, followed by Hongta pepper and Hongfeng dried pepper, and other varieties are less resistant to navel rot.
Four. conclusion
1. High yield: Hongfeng dry pepper has the highest yield, followed by American sweet pepper.
2. Stress resistance: Jinhong dried pepper has strong drought tolerance, and the incidence of umbilical rot is low, followed by Hongta dried pepper and Hongfeng dried pepper.
3. Production suggestions; Through the comparative test of seven varieties of pigment pepper, it can be seen that under the reasonable cultivation mode and current cultivation management conditions, it is easy to obtain high yield because of the early maturity of Hongfeng dry pepper and line pepper; In the current situation of water shortage, it is advisable to choose Hongfeng dried pepper with strong stress resistance and high yield; Hongfeng dry pepper and American sweet pepper should be selected in plots with good water and fertilizer conditions.
