What are the key points of cultivation and management of fragrant peas?

1. Sow seeds and raise seedlingsThe weight of the seeds is about 80 grams. The optimal germination temperature of seeds is 20; Budding occurs in about 13 days at alternating temperatures of 29 days and 21 nights. Soak the seeds with 65 warm water before sowing, and about 30% of the hard seeds do not swell after soaking, and it is difficult to germinate.

To use a knife to gently scratch the seed coat one by one, pay attention not to hurt the seed umbilicus during the operation, and then soak the hard seeds in warm water for 1-2 hours, and then expand rapidly and are easy to germinate. <>

2. Land preparationContinuous cropping should be avoided in the planting area. Appropriate basal fertilizer should be applied before land preparation. Fragrant pea is a less fertilizer crop, but the proportion of phosphorus and potassium should be increased appropriately, and the total amount of fertilizer is about 1 20 of more fertilizer plants (such as caryophyllus), and it can be applied per 100 square meters of planting area

Kilograms of nitrogen fertilizer, kilograms of phosphate fertilizer, kilograms of potassium fertilizer. The type used as a base fertilizer: compost or manure with humus 200-300 kg and add 3 kg of superphosphate.

In acidic soil areas, lime can be used to adjust the pH. <

Cultivation management of fragrant peas: When the potted seedlings are about 10 cm high in the warm land in the south, they can be depotted and planted in the cold room. Row spacing 30-40 cm, plant spacing 15-20 cm.

Many potted plants in the north, cultivated in the greenhouse in winter, placed in a sunny place, changed from a small pot to a large pot with the growth of the plant, the main vine can be removed when the main vine is elongated to 15 cm, and the side vines can increase the flower buds. And use thin bamboo vertical lure to tie the branches one after another.

During the cultivation period, the temperature should not be too high, 9 13 during the day and 5 8 at night before flowering; The temperature can be slightly increased during flowering, from 15 to 20 during the day and 10 to 13 at night. The cultivation environment must be so that it can see direct sunlight and good ventilation, otherwise it is easy to cause plant growth and bud dropping. Before flowering, liquid fertilizer should be applied once every 7 10 days, and potassium dihydrogen phosphate should be applied 2 or 3 times in the early stage of flower bud formation, and flowers can be seen in spring and early spring.

If only 1 side branch is left in each leaf axil when used as cut flowers, the quality of cut flowers can be improved.

Cut flowers should be selected for full bloom, and the buds that have not yet opened cannot be re-opened once they are cut. Fragrant peas are self-pollinated, and there is no risk of hybridization, and the seeds are ripe in different sequences, and the pods turn yellow respectively.

The thing that needs to be paid attention to when sowing fragrant peas is to disinfect the seeds of fragrant peas, and to ensure the growth temperature of fragrant peas, and to ensure the density of planting when planting, to fertilize the soil after planting, and to strictly control the water and fertilizer management of fragrant peas, which are all things that need to be paid attention to.

It is necessary to pay attention to reasonable water and fertilizer management, but also need to be watered regularly, when sowing should also choose some good quality seeds, but also pay attention to providing relatively high-quality fertile soil, but also should pay attention to the environmental management of pea sowing, and regularly spray pesticides to prevent and control pests and diseases.

Be sure to sterilize the soil and seeds when planting, because this will be beneficial to their growth, and then you must not water too much water in the summer, because too much water will cause root rot and make the yield particularly low.

It is necessary to pay attention to the time of planting, the soil and seeds, and later after the seedlings are pruned, flowering, watering, fertilizing, and sun bathing.

Peas are prone to grass shortage at the seedling stage, and must be cultivated and weeded 2 3 times. Creeping peas must be erected when the plant height is about 30 cm, otherwise the stems and vines creeping on the ground, which is not only inconvenient for field management and harvesting, but also the lower stems and leaves are easy to rot and cause diseases. Pea fertilization should be based on basal fertilizer.

In addition to the application of compost and manure, more phosphorus and potassium fertilizers, such as plant ash and bone meal, should be applied. If you can use rhizobia to dress seeds when sowing, the effect is better. Peas are poor drought tolerant and should be irrigated to keep the soil moist during the growing period.

In the event of drought after sowing, it is necessary to irrigate quickly to facilitate seed germination and emergence. It requires more water during the flowering and podding stage.

1) Land preparation: northern peas are sown in spring, after the previous harvest, stubble weeding, deep turning, full organic fertilizer, irrigation in winter, and rake to protect moisture after thawing the soil surface in the following year. In areas with more rain in the south, ditches should be opened to make drainage and irrigation smooth.

2) Sowing: early spring sowing in the north, sowing date 3-4 months; The winter sowing period in the south is 10 to 12 months, and the autumn sowing period is 8 to September. Under the general soil fertility level, 751,050,000 peas per hectare; Plots of semi-leafless peas with medium fertility or above, 1.2 million 2 million plants per hectare.

3) Water and fertilizer management: based on base fertilizer, in addition to compost and manure, more phosphorus and potassium fertilizers should be applied, such as plant ash, bone meal, etc. Diammonium phosphate can also be applied as basal fertilizer and seed fertilizer.

Spraying boron, manganese, molybdenum and other trace element fertilizers at the flowering and podding stage had a significant effect on increasing yield. In the northern spring sowing area, peas should be watered 2 3 times during the flowering and pod-setting stage, and once every 10 days or so. In the rainy areas in the south, deep ditches and high furrows should be paid, and attention should be paid to drainage.

4) Cultivating and weeding: the first tillage when the plant height is 5 7 cm, the second tillage when the plant height is 15 20 cm, and the third time can be flexibly mastered according to the growth of peas. Weeds should be pulled out in time in the later stages of growth.

The field management of pea cultivation should first grasp the sowing time, the sowing time is different according to the climate, and the peas cultivated in the winter are generally sown from late October to mid-November.

Soil: Fertile, well-drained soil should be used for cultivating peas. Watering:

During the growth stage, water should be replenished in time, and it can be watered once every 2-3 days. Light: Sufficient light should be given during the vigorous growth period, and it should not be exposed to direct sunlight.

Temperature: It should be given a growth environment of 9-13 before flowering, and the temperature should be controlled at 15-20 during the flowering period.

1. Soil. Fertile and well-drained soil should be used for cultivating fragrant peas, and humus, garden soil and cake fertilizer can be used for preparation.

2. Watering. In the stage of its growth, it is necessary to replenish water in time, and it can be said that the parsley should be watered once every 2-3 days and properly ventilated. It does not like to grow in too humid environments and should be watered sparingly. If there is water accumulation due to excessive watering, it will cause the roots of the Keibi plant to rot.

3. Illumination. Fragrant peas should be given sufficient light during the vigorous growth period, and the temperature is high and the light is strong in summer, so shading measures should be taken in time. Do not let it be exposed to direct sunlight, you can spray water into the breeding environment appropriately, which can reduce the temperature and enhance the humidity of the air.

Fourth, temperature. It should be given a 9-13 growing environment before flowering, and the temperature should be controlled at about 5-8 at night. If the temperature is too high, it will affect its growth. It is best to control the temperature at 15-20 during the flowering period.
