A pumpkin
seed, also known as a pepita, is the edible seed of a pumpkin or certain other cultivars of squash. The
seeds are typically rather flat and asymmetrically oval, and light green in color and may have a
white outer hull. The seeds are nutrient-rich, with especially high content of protein, dietary
fiber and numerous micronutrients. Chinese pumpkin seed grow in Northwest and Northeast of China.
Our company has our own factory processing the pumpkin seed. The word can refer either to the hulled kernel or
unhulled whole seed, and most commonly refers to the roasted end product.

Control methods:
1. Soil testing and formula fertilization: According to the content of nutrients in the soil, reasonable application of organic fertilizers and chemical fertilizers to increase soil calcium content.
2. Apply topdressing as appropriate: According to the growth of cabbage, topdressing nitrogen fertilizer at the appropriate time, do not apply too much nitrogen fertilizer, otherwise it will affect the root absorption of calcium.
3. Reasonable irrigation: If the soil is too dry and the air humidity is too high, it will affect the absorption and operation of calcium. Therefore, we must irrigate according to soil moisture.
4. Extra-calcium supplement: When the leaf ball begins to form, spray 0.5% calcium chloride solution to the new leaf every 5 to 7 days, and spray 3 to 5 times.
5. The use of hormones to "activate" calcium: spraying naphthalene acetic acid on the leaves promotes the absorption and transport of calcium.

Prevention and cure of dry heart disease in Chinese cabbage
Cabbage dry heart disease known as "dry heart" is also one of the diseases that affect cabbage production. The main reasons for this are the lack of calcium in the soil, dryness, excessive application of nitrogen fertilizer, excessive air humidity, and the antagonistic effects of sodium, potassium, and ammonium on calcium, which can lead to calcium deficiency in Chinese cabbage and eventually produce dry heart disease.
