Cultivation Technique of Sweet Pepper

(1) Land selection: In order to harvest intact mature fruits, it is necessary to strengthen the development of the root groups. In order to make the fruits absorb sufficient water in the mature period, the well-drained, organic-rich materials should be selected, and the ventilation and water retention should be good. Sandy loam or loam, and no-roots nematode contaminated land cultivation. Soils that are easy to dry and have poor water retention are not suitable for cultivation. If they are cultivated in paddy fields, they should be used as sorghum (more than 30 cm) to facilitate drainage and increase the ventilation in the soil. Such soil conditions will not hinder inorganic nutrients and calcium. Absorption, and fruit shape, fruit top rot disease occurs less. The soil reaction is preferably about pH 6.5. Soils with low oxygen, poor ventilation, wet or dry soil, poorly developed root groups, affect the absorption of nutrient water, lead to a decline in photosynthesis, the plant potential can not be maintained for a long time, and are not suitable for the cultivation of mature fruits, so it is suitable Appropriateness is the first requirement.

(B) strong seedlings is the first step in the cultivation success: seedlings can be ordered to the nursery or workers to raise their own seedlings, suitable for the use of 80-hole plug, and the use of Montreal Wang No. 3 medium; nursery sites selected sufficient sunlight, In well-ventilated areas, if there is insufficient sunshine, the cotyledons are slender and the hypocotyls are long. The cotyledons will fall off early and affect the growth after rain. The healthy seedlings have large cotyledons and thick embryonic axes, so that the healthy seedlings survive quickly after colonization, and the carbohydrates or nitrogen compounds accumulate smoothly, producing auxin or stilbene and promoting flower bud differentiation. The flower buds of sweet peppers differentiated and spread in two leaves of this leaf. When the third leaf began to spread, flower buds differentiated into the interior and entered the reproductive growth period. In order to make flower buds differentiate well, it is better to spray phosphate seed 500 times in sufficient time to supply phosphoric acid, especially when the night temperature is higher (23 °C). In general, when the temperature is high at night, the respiratory rate is large, and the petiole is long; when the night temperature is low (18°C), the petiole is short and thick, and the seedlings are abundant.

(3) Density for planting: When harvesting mature fruits, the fruit is easy to weaken due to the long time and heavy load on the stems. In order to fully bathe the leaves under the fruit position, the plant spacing should be 65 cm and 45 cm, ie 130 cm wide (including sulcus) planted in two rows. In order to reduce bacterial wilt, it is advisable to control the ground temperature below 25C. To achieve this goal, a layer of rice straw shall be placed in the center (between rows and rows) of the earthworms and covered with silver plastic cloth. A layer of straw becomes a heat-insulating layer, and secondly, it reduces the evaporation of soil moisture so as to avoid excessive drying of the soil. In addition, less weeds occur, the locusts are lightly harmed, and virus diseases rarely occur, which does not hinder the operation of planting holes.
