The setting of the summer squash is very important. Do you know that the road setting should pay attention to it? Next, I will introduce you to the detailed question of the value of the zucchini.
The problem of the value of the zucchini needs to be noted:
1. After 30-35 days of seedling management, seedlings with 3-4 true leaves can be cultivated for colonization.
2. Apply enough base fertilizer before planting. Acre of high-quality farmyard manure 3000-5000 kg, can also be applied to horse manure, sheep manure and so on.
3. After the whole land is completed, the ridges with a distance of 60-65 cm will be planted at a distance of 40-50 cm, and 2000-2500 plants per acre will be planted. It can also be made into a 1.3-meter-wide flat raft, with two rows per raft.
4. When planting the seedlings, sit on the water planting. After the water seeps, seal and fix the melons.
5. The planting safety period is above 13 °C, and the nighttime temperature is not lower than 10 °C.
6. After the slow seedlings should be topdressed (apply 150-200 kg of cake fertilizer, or 50-60 kg of ternary compound fertilizer), and poured "revitalized water", but because of the low ground temperature, it is not appropriate to water too much. After that, the soil should be ploughed in time, no water and fertilizer should be applied, and the first melon should be watered until it reaches 10-12 cm. After the melon is dried, it is usually watered once every 5-7 days to keep the topsoil moist, and the rainy season needs to be drained.
7. The seasoning of the melon is followed by the top dressing, and the general topdressing is 2-3 times. Each application of manure is 1000-1500 kg/mu, or ammonium carbonate 10-15 kg/mu.
8. Pay attention to the management of water and fertilizer. When the seedling stage or the first female flower is in the fruit setting period, the water will be too long. If the water and fertilizer are not kept up, the yield will decrease. In addition, excessive fruit retention in the early stage is likely to cause poor development of the pupa and affect the total yield.
9. For early maturity and high yield, artificial pollination should also be carried out (especially when there is no insect pollination). Every day from 6-8 am, the male flowers that are being opened are taken down, the corolla is peeled off, the stamens are exposed, and the female flower stigma is applied several times.
10. If you need to keep the seeds, you should generally select the melons in the later stage, otherwise the yield will be affected; the plants that are specially kept will not be subject to this limitation.
Solar water heating system is a cost-effective system for residential hot water application. This system is designed according to thermosiphon principle and operating with proportion difference between cold and hot water. The water heated by vacuum tubes is held in the stainless steel storage tank where the insulation preserves the heat.
The thermosiphon Solar Water Heater uses the sun to heat the working fluid (mostly water) in the Vacuum Tubes. The Solar Collector absorbs solar radiation, and converts the sunlight to heat and transfer it to the water. The heated water naturally rises through the solar collector into the water tank where the cooler water at the bottom of the tank is forced out and descends to the bottom of the collector (thermosiphon circulation). The circulation will be interrupted when there is no solar radiation.
