1 morphological characteristics and economic value

Seed zucchini is a kind of Cucurbitaceae crop that collects seeds specially. The vine is thick, the leaf is shaped like heart, grows fast, the colony structure is good, the whole growth period is 98 D, the melon shape is round or oval, the immature is dark green, the ripe fruit is golden yellow, the weight of single melon is 2.0 ~ 3.5 kg, the number of single melon seeds is 320 ~ 680, the weight of 1000 seeds is 162 g, the seeds are dark green, and it has good commodity. Zucchini seeds are good dietary supplement because they are rich in vitamin C, Cucurbita B, potassium and phosphorus, it is also an ideal raw material for making cosmetics.

Get ready for 2

Zucchini is not strict with soil conditions. Heavy clay, low wetland, strong acid (pH 6-8) , strong alkaline (salt content not more than 0.3%) soil, can be planted. Most suitable for flat terrain, good drainage, deep sandy soil and loam. Afraid of water stains, avoid repeated cropping, continuous planting. The previous crop should not be melons.

The former crops should turn over in time after harvest, the mature soil can improve fertility, the whole layer fertilization can apply organic fertilizer 2-3.5 M3666.7 m2, diammonium hydrogen phosphate fertilizer 20-25 KG666.7 m2, potassium fertilizer 5 KG666.7 m2. After Spring Snow melts, soil moisture should be preserved in time, soil preparation should be done carefully, the ground should be leveled, soil should be broken, and soil moisture should be preserved for sowing.

3 variety selection

At present, the varieties planted in the peripheral division are Fuxin 2, Light Plate 1, Light Plate 2, golden apple, etc. This year, the experimental plant orders to plant the varieties of Tiger Brand 2, Hope 909,9, etc. . The selection of zucchini varieties should be based on the local climate conditions, select high yield, adapt to the region's fine zucchini varieties.

4 sowing

Generally in late April to early May sowing, appropriate early sowing can increase yield. When the soil temperature of 125PX is stable above 10 °C, the seeds can be sown.

The sowing quantity was calculated according to seed purity and germination rate. The general sowing quantity is 500-600g/666.7 m2.

It can be seeded by manual and mechanical precision. On-demand sowing can be divided into direct seeding and seed soaking to promote germination. This year we will carry out mechanical precision broadcasting. One point at a time.

0.7-0.9 m film, 1 film and 1 tube, 40-60 cm spacing can be used. The plant spacing was 35-40 cm, one seed was sown in each hole, and the depth was 2-3 cm. It can also be seeded with 2.05 m wide film and 4 rows of film. Then it's on demand. 2500-3500 plants/666.7 m2. Sowing end straight, row spacing consistent, seed uniform, consistent depth, width isometric, to the end to the edge.

5 post-broadcast management

After sowing, “Check seed, check film, check belt, check moisture, fill seed, fill film, fill belt, fill moisture” and so on. Drop out seedling water in time, the amount of dripping water is about 15m 3/666.7 m 2, to ensure the whole seedling, seedling evenness, seedling evenness. After the emergence of water drops, that is, plowing 1 time. The intertillage was carried out twice after the seedling and the depth was from L2 to 1200px, so as to increase temperature and retain moisture and loosen the soil and weed.

Six drops of water

The seedling stage control irrigates, squats the seedling suitably, raises the strong seedling. Generally in early June irrigation head water, the amount of water dripping 30-40 m3/666.7 m2, then according to the growth and moisture, 10 days about a drop of water. Dripping water 5-6 times during the whole growth period. The water drop was 100-160m3/666.7 m2.

7 fertilize

General 1 Water 1 fertilizer with water drop. Application of urea 2-3k666.7 m2 and Monopotassium phosphate 1-2k666.7 m2 at seedling stage promoted root development and shoot growth. Application of urea 2-3k666.7 m2 and Monopotassium phosphate 1-2k666.7 m2 at trailing stage promoted root development and shoot growth, in flowering and fruiting period, the application of urea 2-3 KG666.7 m2 and Monopotassium phosphate 2-3 KG666.7 m2, nitrogen fertilizer and phosphorus fertilizer should be controlled, so as to ensure the flower number is beneficial to increase yield In the period of fruit expansion, urea 3-4 KG666.7 m2 and Monopotassium phosphate 1-2 KG666.7 m2 were applied in order to promote fruit expansion and seed filling, while urea l-2 KG666.7 m2 was applied in the later period to keep plant bright green. After the 2 cotyledons were fully expanded and 1 heart leaf was exposed, and the melons were seated and sprayed 1 time each. Spraying foliar fertilizer and micro-fertilizer 1-2 times at seedling stage, trailing stage, flowering and fruit-bearing stage and fruit-expanding stage can improve the photosynthesis of the plant, which is beneficial to the healthy growth and increase the yield of zucchini.

8 artificial or bee pollination

Calabash is a cross-pollinated crop, which relies on insect vectors such as bees to transmit pollen. Under the condition of natural pollination, artificial assistant pollination is very advantageous to increase yield. Male flowers are usually picked at 06:00-10:00 in the morning along with their pedicels and corolla peeled off and then smeared on the female flowers. Pollen is directly smeared on the stigma, and the stigma should not be touched by hand. Usually leaves 1-2 melons per plant.

Nine pest control

The main diseases and pests of seed squash are fusarium wilt, powdery mildew, downy mildew, virus disease, ground tiger, aphid, red spider, etc. . Powdery mildew and virus diseases are the main diseases that harm the growth and affect the yield. During the whole growth period, it is mainly to prevent, spraying once every 7-10 days, spraying first and then dripping, spraying in time after rain, alternative use of fungicides to avoid plant resistance, reduce the efficacy. The main medicament has the grass fruit farmer, the suspension flow, methyl thiophanate, Mancozeb, triadimefon, chlorothalonil, carbendazim and so on.

10 timely harvest

Zucchini harvest time requirements are not strict, gourd yellow, branches withered, can be picked manually, placed in a cool ventilated place, after ripening about 15-20 days. Melon picking should also avoid too late to cause rotten melon or germination.
